Cultural habits : The travel writing of Isabella Bird, Max Dauthendey and Ai Wu, 1850-1930
Creators: name: Ng, Maria Noelle
Publisher: name: University of British Columbia
Year: 2009

description: Edward Said’s Orientalism (1978) has generally been recognized as an influential study of western literary perceptions of the East, but numerous critics have also challenged his geographical parameters as too narrow and his conceptual framework as insufficiently complex. This thesis further expands the study of Orientalism (1) by focussing on a colonized area generally overlooked in this context, namely Southeast Asia; (2) by including a writer of German background, a nationality frequently omitted in the discussion of colonial history in general and of Orientalism in particular; and (3) perhaps most importantly, by juxtaposing the views of a Chinese author with those of western writers. This thesis is the critical study of three authors about their travels in Southeast Asia: Isabella Bird (1831-1904), Max Dauthendey (1867-1918) and Ai Wu (1904-1992). Since postcolonial criticism does not generally concern itself with the cultural habits which are formed in a traveller’s native society prior to his or her departure, this approach alone does not provide the tools for the differentiated kind of investigation I wish to conduct. I therefore draw on the cultural criticism of Pierre Bourdieu (1972, 1979, 1993), Johannes Fabian (1983, 1991), and Walter Benjamin (1969, 1974, 1985), to focus on a decisive moment in each traveller’s background, which may be said to have shaped his or her perception of other cultures. In Bird’s case, this event was the 1851 Exhibition which encapsulated the Victorian ideals of industrial progress, imperial expansion, and Christian philanthropy. By contrast, Dauthendey’s responses were shaped by the Art Nouveau sensibilities he bad acquired in the German, French, and Scandinavian bohème. Finally, Al Wu derived his outlook from the May Fourth Movement, a brief period when western ideas were welcomed into Chinese social and literary history. Said’s Orietalism posits the homogeneous cultural entity of an imperial West in contradistinction to a victimized East. This thesis does not reverse these categories, but it does provide the space for an equal discussion of Chinese and western writings within a differentiated historical context.

description: The main task of the Target Tracker detector of the long baseline neutrino oscillation OPERA experiment is to locate in which of the target elementary constituents, the lead/emulsion bricks, the neutrino interactions have occurred and also to give calorimetric information about each event. The technology used consists in walls of two planes of plastic scintillator strips, one per transverse direction. Wavelength shifting fibres collect the light signal emitted by the scintillator strips and guide it to both ends where it is read by multi-anode photomultiplier tubes. All the elements used in the construction of this detector and its main characteristics are described.

description: In the first half of this article, we review the Steinberg theory for double flag varieties for symmetric pairs. For a special case of the symmetric space of type AIII, we will consider $ X = GL_{2n}/P_{(n,n)} \times GL_n / B_n^+ \times GL_n / B_n^- $ on which $ K = GL_n \times GL_n $ acts diagonally. We give a classification of $ K $-orbits in $ X $, and explicit combinatorial description of the Steinberg maps. In the latter half, we develop the theory of embedding of a double flag variety into a larger one. This embedding is a powerful tool to study different types of double flag varieties in terms of the known ones. We prove an embedding theorem of orbits in full generality and give an example of type CI which is embedded into type AIII.

description: Self-oscillating systems, described in classical dynamics as limit cycles, are emerging as canonical models for driven dissipative nonequilibrium open quantum systems, and as key elements in quantum technology. We consider a family of models that interpolates between the classical textbook examples of the Rayleigh and the van der Pol oscillators, and follow their transition from the classical to the quantum domain, while properly formulating their corresponding quantum descriptions. We derive an exact analytical solution for the steady-state quantum dynamics of the simplest of these models, applicable to any bosonic system---whether mechanical, optical, or otherwise---that is coupled to its environment via single-boson and double-boson emission and absorption. Our solution is a generalization to arbitrary temperature of existing solutions for very-low, or zero, temperature, often misattributed to the quantum van der Pol oscillator. We closely explore the classical to quantum transition of the bifurcation to self-oscillations of this oscillator, while noting changes in the dynamics and identifying features that are uniquely quantum.
Hyperfine Interactions in the Heavy Fermion CeMIn_5 Systems

description: The CeMIn_5 heavy fermion compounds have attracted enormous interest since their discovery six years ago. These materials exhibit a rich spectrum of unusual correlated electron behavior, and may be an ideal model for the high temperature superconductors. As many of these systems are either antiferromagnets, or lie close to an antiferromagnetic phase boundary, it is crucial to understand the behavior of the dynamic and static magnetism. Since neutron scattering is difficult in these materials, often the primary source of information about the magnetic fluctuations is Nuclear Magnetic Resonance (NMR). Therefore, it is crucial to have a detailed understanding of how the nuclear moments interact with conduction electrons and the local moments present in these systems. Here we present a detailed analysis of the hyperfine coupling based on anisotropic hyperfine coupling tensors between nuclear moments and local moments. Because the couplings are symmetric with respect to bond axes rather than crystal lattice directions, the nuclear sites can experience non-vanishing hyperfine fields even in high symmetry sites.

For the first time the magnetized volume qualified for electron cyclotron resonance at 2.45 GHz and 87.5 mT has been analyzed in highly detailed 3D simulations with unprecedented resolution. New results were obtained from the numerical simulation of 25211 electron trajectories. The evident characteristic ion sputtering trident of hexapole confined ECR sources has been identified with the field and electron trajectory distribution. Furthermore, unexpected long electron trajectory lifetimes were found.

description: The climate on early Mars is one of the major unsolved problems. It is unclear whether early Mars was warm and wet or cold and icy. Morphological features on Mars such as sinuous ridges could provide critical constraints to address this issue. Here we investigate several sinuous ridges to the east of Tempe Terra, Mars and find they may have recorded persistent fluvial activity on early Mars. Our analysis indicates that these ridges may represent exhumation of the channel belts and overbank deposits formed from meander rivers over significant geologic time. Layered smectite-bearing minerals, distributed along the ridge flanks, could be detrital or authigenic floodplain clays. Our interpretation of the stratigraphic relationships indicates that the layered smectite-bearing materials lie between channel belt deposits, supporting the floodplain interpretation. Our results suggest that a persistent warming event has persisted for a geologically significant interval (>1500 yr) during the Noachian period of Mars.

description: The inclusion of the quantum fluctuations of the metric in the geometric action is a promising avenue for the understanding of the quantum properties of gravity. In this approach the metric is decomposed in the sum of a classical and of a fluctuating part, of quantum origin, which can be generally expressed in terms of an arbitrary second order tensor, constructed from the metric, and from the thermodynamic quantities describing matter fields. In the present paper we investigate the effects of the quantum fluctuations on the spherically symmetric static black hole solutions of the modified field equations, obtained from a variational principle, by assuming that the quantum correction tensor is given by the coupling of a scalar field to the metric tensor. After reformulating the field equations in a dimensionless form, and by introducing a suitable independent radial coordinate, we obtain their solutions numerically. We detect the formation of a black hole from the presence of a singularity in the metric tensor components. Several models, corresponding to different functional forms of the scalar field potential, are considered. The thermodynamic properties of the black hole solutions (horizon temperature, specific heat, entropy and evaporation time due to Hawking luminosity) are also investigated.

Neural and hormonal control of blood pressure and vascular conductance during hemorrhage in hypertensive rabbits
Creators: name: Weichert, Gabriele Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: The cardiovascular response to hemorrhage has been well characterized in conscious normotensive rabbits. When the autonomic nervous system is intact, baroreflex mechanisms cause peripheral vasoconstriction and tachycardia, thereby maintaining blood pressure. When the autonomic nervous system is blocked, the vasoconstrictor hormones vasopressin (AVP) and angiotensin II (ANG Il) are released early during hemorrhage, and have significant effects on peripheral vascular tone and maintenance of blood pressure. In hypertension, the reflex control of blood pressure in response to hemorrhage is not well understood. It was the goal of the experiments performed in this thesis to characterize the control of blood pressure and vascular conductance during hemorrhage in conscious renal wrap hypertensive rabbits. In particular, direct blood flow measurements allowed the control of hindlimb, mesenteric and renal vascular conductance to be characterized. In addition, a morphological analysis of hindlimb, mesenteric and renal blood vessels from renal wrap hypertensive rabbits was performed in order to further understand functional alterations to the vasculature in this hypertensive model. During hemorrhage, renal wrap hypertensive rabbits had an impaired ability to control blood pressure. When the autonomic nervous system was intact, this was associated with an impaired ability to control heart rate and hindlimb conductance. When the autonomic nervous system was pharmacologically blocked, the impaired ability to control blood pressure was associated with an impairement in hormonally mediated (AVP and ANG II) control of hindlimb vascular conductance. There was no evidence to suggest that neural or hormonal control of renal and mesenteric vascular conductance was impaired in the hypertensive rabbits during hemorrhage. Morphological analysis of hypertensive blood vessels showed that the hindlimb, renal and mesenteric blood vessels had an increased wall-to-lumen ratio indicative of non-specific vascular hyper-responsiveness. The impaired ability of the hypertensive rabbits to control blood pressure during hemorrhage was associated with an impaired ability to control the hindlimb, but not the mesenteric and renal vascular beds. These findings suggest that, in renal wrap hypertensive rabbits, there is either a differential control of sympathetic nerve activity or that there is a differential degree of vascular reactivity to these individual vascular beds.
Formation and early evolution of massive black holes

description: The astrophysical processes that led to the formation of the first seed black holes and to their growth into the supermassive variety that powers bright quasars at redshift 6 are poorly understood. In standard LCDM hierarchical cosmologies, the earliest massive holes (MBHs) likely formed at redshift z~15 at the centers of low-mass (M>5e5 solar masses) dark matter ``minihalos'', and produced hard radiation by accretion. FUV/X-ray photons from such ``miniquasars'' may have permeated the universe more uniformly than EUV radiation, reduced gas clumping, and changed the chemistry of primordial gas. The role of accreting seed black holes in determining the thermal and ionization state of the intergalactic medium depends on the amount of cold and dense gas that forms and gets retained in protogalaxies after the formation of the first stars. The highest resolution N-body simulation to date of Galactic substructure shows that subhalos below the atomic cooling mass were very inefficient at forming stars.

description: Macroscopic polarity and its dynamic response to external electric fields and temperature in the nominally ergodic relaxor phase of pristine lead magnesium niobate crystals and ceramics, Pb(Mg1/3Nb2/3)O3 (PMN), were investigated. Dynamic pyroelectric measurements provide evidence for persistent macroscopic polarity of the samples. Annealing experiments below and above Burns temperature of polarized samples relate this polarity to the presence of polar nano entities and their dynamics. The dc electric field strength required for macroscopic polarization reversal is similar to the amplitude of the ac field where dynamic nonlinear dielectric permittivity reaches maximum. Consequently, the aforementioned maximum is related to the reorientation of polar nano entities. The results question the existence of an ergodic state in PMN below Burns temperature.

Unconstrained Astrometric Orbits for Hipparcos Stars with Stochastic Solutions

Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: A considerable number of astrometric binaries whose positions on the sky do not obey the standard model of mean position, parallax and linear proper motion, were observed by the Hipparcos satellite. Some of them remain non-discovered, and their observational data have not been properly processed with the more adequate astrometric model that includes nonlinear orbital motion. We develop an automated algorithm based on "genetic optimization", to solve the orbital fitting problem with no prior information about the orbital elements is available (from, e.g., spectroscopic data or radial velocity monitoring). We test this method on Hipparcos stars with known orbital solutions in the catalog, and further apply it to stars with stochastic solutions, which may be unresolved binaries. At a confidence level of 99%, orbital fits are obtained for 65 stars, most of which have not been known as binary. A few of the new probable binaries with A-type primaries with periods 444-2015 d are chemically peculiar stars, including Ap and λBoo type. The anomalous spectra of these stars are explained as admixture of the light from the unresolved, sufficiently bright and massive companions. We estimate the apparent orbits of four stars which have been identified as members of the 300 Myr-old UMa kinematic group. Another four new nearby binaries may include low-mass M-type or brown dwarf companions. Similar astrometric models and algorithms can be used for binary stars and planet hosts observed by SIM PlanetQuest and Gaia.

description: We investigate the conditions under which the first low-mass stars formed in the universe by confronting theoretical predictions governing the transition from massive Population III to low-mass Population II stars with recent observational C and/or O abundance data of metal-poor Galactic stars. Based on an existing theory, we introduce a new "observer-friendly" function, the transition discriminant D_trans, which provides empirical constraints as well as a powerful comparison between the currently available data of metal-poor halo stars and theoretical predictions of the formation of the first low-mass stars (<1 M_sun). Specifically, we compare the empirical stellar results with the theory that fine-structure lines of C and O dominate the transition from Pop III to Pop II in the early universe. We find the observational data for halo objects as well as for dSph galaxies and globular clusters to be consistent with this theory. An explanation for the observed lack of metal-poor stars in dSph galaxies and globular clusters is also suggested. Finally, we predict that any star to be found with [Fe/H]

Local knowledge in physical design and planning : a case study of Chiangmai, Thailand
Creators: name: Vadhanasindhu, Pongsak
Publisher: name: University of British Columbia
Year: 2009

description: This study concerns “local knowledge” - the knowledge of local people - and the role it can play in improving development projects. The study adds to previous definitions of local knowledge, describes how Thai designers and planners treat this knowledge, and illustrates the consequences of including or excluding its consideration in planning development projects. The research approach is a case study of design and planning in Chiangmai, a province in northern Thailand. Both primary data and secondary data were collected and analyzed. Primary sources were personal observations, individual interviews and focus group discussions. Secondary sources included others’ studies of architectural knowledge and planning reports. The existing literature, including literature in local knowledge, planning, citizen participation and social impact assessment, is still grappling with the issue of local knowledge and its inclusion or exclusion in development project planning. The study found that local people have a powerful base of information that is potentially valuable to the design and planning of development projects. Local knowledge can be technical, descriptive, explanatory, prescriptive, subtle, dynamic, scattered and holistic. An often ignored form of local knowledge is local people’s perceptions and values which have been made explicit through the impact that development projects have had on their social organization, their economy and their natural environment. Although the knowledge held by local people could provide real benefit to the design and planning professions, it has been overlooked by many professionals who have a limited awareness of the richness and value of local knowledge. The study found that awareness and use of local knowledge are affected by professional training and by planning procedures. This thesis concludes that for local knowledge to be appropriately and effectively involved in design and planning, procedures need to be restructured to require or encourage professionals to actively seek local knowledge, to respect this knowledge and its owners, and to include this knowledge in their professional work through consultation with local people. In order for this restructuring to be effective, design and planning education must include opportunities for students to learn how to gain and apply local knowledge in a respectful manner.

description: The antivortex is a fundamental magnetization structure which is the topological counterpart of the well-known magnetic vortex. We study here the ultrafast dynamic behavior of an isolated antivortex in a patterned Permalloy thin-film element. Using micromagnetic simulations we predict that the antivortex response to an ultrashort external field pulse is characterized by the production of a new antivortex as well as of a temporary vortex, followed by an annihilation process. These processes are complementary to the recently reported response of a vortex and, like for the vortex, lead to the reversal of the orientation of the antivortex core region. In addition to its fundamental interest, this dynamic magnetization process could be used for the generation and propagation of spin waves for novel logical circuits.

description: We extend the recently introduced setting of coherent differentiation for taking into account not only differentiation, but also Taylor expansion in categories which are not necessarily (left)additive. The main idea consists in extending summability into an infinitary functor which intuitively maps any object to the object of its countable summable families. This functor is endowed with a canonical structure of bimonad. In a linear logical categorical setting, Taylor expansion is then axiomatized as a distributive law between this summability functor and the resource comonad (aka.~exponential), allowing to extend the summability functor into a bimonad on the Kleisli category of the resource comonad: this extended functor computes the Taylor expansion of the (nonlinear) morphisms of the Kleisli category. We also show how this categorical axiomatizations of Taylor expansion can be generalized to arbitrary cartesian categories, leading to a general theory of Taylor expansion formally similar to that of differential cartesian categories, although it does not require the underlying cartesian category to be left additive.We provide several examples of concrete categories which arise in denotational semantics and feature such analytic structures.

description: In this paper we explore an evolutionary Unified scenario involving super massive black hole and starburst with outflow, that seems capable of explaining most of the observational properties of at least part of AGNs. Our suggestion is explored inside the expectations of the Starburst model close associated with the AGN where the NLR, BLR and BAL region are produced in part by the outflow process with shells and in compact supernova remnants. The outflow process in BAL QSOs with extreme IR and Fe II emission is studied. In addition, the Fe II poblem regarding the BLR of AGN is analysed. Neither the correlations between the BAL, IR emission, FeII intensity and the intrinsic properties of the AGN are clearly understood. We suggest here that the behaviour of the BAL, IR and FeII emission in AGNs can be understood inside an evolutionary and composite model for AGNs. In our model, strong BAL systems and Fe II emission are present (and intense) in young IR objects. Orientation/ obscuration effects take the role of a second parameter providing the segregation between Sy1/Sy2 and BLRG/NLRG.

Antiferromagnetic resonance in a spin-gap magnet with strong single-ion anisotropy

description: Quasi-one-dimensional magnet NiCl$_2\cdot$4SC(NH$_2$)$_2$, usually abbreviated as DTN, does not order at zero field down to $T=0$: due to the strong single-ion anisotropy of the "easy plane" type acting on $S=1$ Ni$^{2+}$ ions, the $S_z=0$ ground state is separated from $S_z=\pm 1$ excitations by an energy gap. Once the magnetic field is applied along the main anisotropy axis, the gap closes at $B_{c1}=2.18$ T and the field-induced antiferromagnetic order arises. The low-energy excitations spectrum of this field-induced ordered state includes two branches of excitations, one of them have to be a gapless Goldstone mode. Recent studies of excitations spectrum in a field-induced ordered state of DTN (T.Soldatov et.al, Phys.Rev.B 101, 104410 (2020)) have revealed that Goldstone mode became gapped as magnetic field deviates from the main symmetry axis. This paper proposes simple description of antiferromagnetic resonance modes of quasi-one-dimensional quantum $S=1$ magnet with strong single-ion anisotropy. The approach used is based on a combination of the strong coupling model for the anisotropic spin chain with the conventional mean-field model of antiferromagnetic resonance. The resulting model fits to the known experimental results without additional tuning parameters.

description: The noise in physical qubits is fundamentally asymmetric: in most devices, phase errors are much more probable than bit flips. We propose a quantum error correcting code which takes advantage of this asymmetry and shows good performance at a relatively small cost in redundancy, requiring less than a doubling of the number of physical qubits for error correction.

Παρουσιάζει τη διαφορά μεταξύ των καναλιών και των μέσων και εξετάζει βαθύτερα κάποια λιγότερο γνωστά αλλά πιο σύγχρονα και δημοφιλή κανάλια. Επίσης, παρουσιάζει τη διαφορά μεταξύ της διήγησης και του transmedia - crossmedia στην παραγωγή των ειδήσεων. Υπογραμμίζει τη σημασία του διαδικτύου στην προώθηση και κυκλοφορία των transmedia δικαιοπαροχών, και καταδεικνύει ότι, μέσω της αισθητικής εμβύθισης, με τη χρήση της αρνητικής δυνατότητας, των αποδημητικών σημάτων, των ερμηνευτικών κωδικών και, κυρίως, την λεπτομερή και συνεπή δημιουργία κόσμων, τα transmedia έργα γίνονται επιτυχημένα και καλά αποδεκτά από το κοινό, με τη δυνατότητα να παραμείνουν ενεργά σε βάθος χρόνου. Καταγράφονται παραδείγματα επιτυχημένων transmedia συλλήψεων. Επιπροσθέτως, με μια πολυμεσική εφαρμογή, επιδεικνύεται ένα παράδειγμα στη διανομή των ειδήσεων. Η διατριβή επίσης παρουσιάζει την οικονομική πτυχή των transmedia δικαιοπαροχών και προτείνει λύσεις για τη βελτίωση στην παραγωγή τους. Τέλος, συζητείται το μέλλον της αφήγησης transmedia.
description: This thesis examines convergence and the nature of transmedia storytelling, comparing it with crossmedia and adaptation. It presents the difference between channels and media/platforms in transmedia and examines closer some of the less mainstream but new and popular channels. There is also a comparison between storytelling and crossmedia - transmedia in news distribution. It highlights the importance of the internet in the promotion and circulation of the transmedia franchises, and it evinces that through the immersion aesthetics with the use of negative capability, migratory cues, hermeneutical codes, and, most importantly, sophisticated world building, the transmedia works can be successful and well received from the audience, with the potential to remain active for years. Examples of successful transmedia works are registered. In addition, with a multimedia application an example in news distribution is demonstrated. This thesis also presents the economical aspects of the transmedia franchises and makes suggestions for the improvement of their production. Finally, the future of transmedia storytelling is discussed.

description: We review recent PIC simulation results which show that double-sided irradiation of a thin over-dense plasma slab with ultra-intense laser pulses from both sides can lead to sustained comoving Poynting flux acceleration of electrons to energies much higher than the conventional ponderomotive limit. The result is a robust power-law electron momentum spectrum similar to astrophysical sources. We discuss future ultra-intense laser experiments that may be used to simulate astrophysical particle acceleration.

description: The onset of the COVID-19 pandemic in 2020 has greatly impacted all forms of social activities globally, including traditional classroom activities across all levels of instruction (kindergarten to universities). While many countries have opted for suspension of lessons, this cannot continue indefinitely and alternative means to continue lessons must be developed. While online and blended learning (including MOOCs) have been an active subject of research and discourse during the pre-pandemic days, onset of the pandemic has suddenly created an immediacy to such means of course delivery, better than any administrator or teaching committee could have done. This creates both a gap and tension in terms of successful and engaging content delivery, where traditional modes of synchronous content delivery is now forced to be brought online. Yet, the situation provides educators with an opportunity to explore the merits and weaknesses of online learning. Thus, this article seeks to outline the challenges and paradigm shifts involved in such synchronous online learning as a replacement for traditional classroom learning, following our experience at SUTD of conducting a full 13-week online physics course between May to August 2020. At the same time, we reflect on the merits brought about by the availability of such technologies that can potentially be translated to the physical physics classrooms.

Στο υλικό περιλαμβάνονται όστρακα αγγείων και τμήματα αγγείων συγκολλημένα από επιμέρους όστρακα, ενώ δεν σώζεται κανένα ακέραιο αγγείο. Η κεραμική που εξετάζεται καλύπτει πιθανότατα το χρονικό διάστημα από β΄ τέταρτο του 7ου αι. π.Χ. ως τον πρώιμο 4ο αι. π.Χ., χρονολόγηση που προκύπτει βάσει στυλιστικών και μορφολογικών κριτηρίων, καθώς το παρόν σύνολο στερείται στρωματογραφικών και ανασκαφικών δεδομένων. Η μελέτη αυτού του συνόλου από το Καραμπουρνάκι, καθώς και της «χαλκιδικιώτικης» κεραμικής στο σύνολο της, οδηγεί σε μια χρήσιμη γενική θεώρηση αυτής της ιδιαίτερης γραπτής κεραμικής παραγωγής του βορειοελλαδικού χώρου, ενώ μέσα από αυτήν διαφαίνονται οι σχέσεις που είχαν αναπτύξει οι κάτοικοι της περιοχής με την Εύβοια, τα νησιά των Κυκλάδων και με περιοχές της Ανατολικής Ελλάδας. Τέλος, πραγματοποιείται μια προσπάθεια εντοπισμού πιθανών κέντρων παραγωγής της στη χερσόνησο της Χαλκιδικής.
description: The main object of this paper is the study of painted “chalkidic” pottery coming from the ancient settlement which was located at Karabournaki, Thessaloniki. The present material contains pottery sherds and fragments of vases made of numerous sherds, but there is no full vase. The pottery examined covers, in all probability, the period from the second quarter of the 7th century B.C. until the beginning of the 4th century B.C., chronology obtained using stylistic and morphological criteria as this material lacks stratigraphic and excavation data. The study of this material from Karabournaki, as well as the “chalkidic” pottery as a whole, leads to a useful overview of this painted category of northern Greece, while through this study one can trace the close relations which were developed between the local residents of this area and people of Euboia, the Cyclades and East Greece. Finally, an effort is made to detect potential centers of production of this pottery located in the peninsula of Chalkidike.

description: The Large Area Proportional Counter (LAXPC) instruments onboard the AstroSat Observatory has observed the X-ray binary system Her X-1 during AstroSat observing sessions AO2, AO3 and TO2. These include observations while Her X-1 is in different stages of its 35 day cycle: Low State, Turn-on to Main High State, peak of Main High State and early decline of Main High State. These observations also include a number of dips and one egress of neutron star eclipse. Here we present light curves and softness ratio analysis for these observations and discuss new features of the spectral changes with 35-day phase and orbital phase. We find a new phenomenon for dips during Main High state: About half of the dips show constant softness ratio as count rate decreases, which has not been seen before, and could be caused by highly ionized matter or very dense cold matter. The other half of the dips show the normal decrease of softness ratio as count rate decreases. These are caused by cold matter absorption and were previously known.

Celestial Eikonal Amplitudes in the Near-Horizon Region

description: We investigate the celestial description of an eikonal amplitude for the scattering of massless scalars mediated by soft gravitons in the near-horizon region of a large eternal Schwarzschild black hole. Our construction thus provides a celestial conformal field theory on the horizon corresponding to a non-perturbative scattering process that accounts for event horizons on asymptotically flat spacetimes. From the \emph{known} two-dimensional near-horizon scattering amplitude computed within the effective field theory framework, we first construct a four-dimensional amplitude in a flat spacetime frame around the bifurcation sphere strictly in a small angle approximation limit. While the kinematics of external particles in this frame at leading order are analogous to a Minkowski spacetime, the eikonal amplitude differs from those about flat spacetime due to the near-horizon scattering potential. We construct a celestial correlator following a Mellin transform that provides an all loop order result, with a universal leading ultraviolet (UV) soft scaling behavior of the conformally invariant cross-ratio, and an infrared (IR) pole for the scaling dimension at each loop order. We argue these properties manifest soft graviton exchanges in the near-horizon region and, consequently, the soft UV behavior of the amplitude.
