description: We present a method which uses colour-colour cuts on SDSS photometry to select white dwarfs with hydrogen rich (DA) atmospheres without the recourse to spectroscopy. This method results in a sample of DA white dwarfs that is 95% complete at an efficiency of returning a true DA white dwarf of 62%. The approach was applied to SDSS Data Release 7 for objects with and without SDSS spectroscopy. This lead to 4636 spectroscopically confirmed DA white dwarfs with g<=19; a ~70% increase compared to Eisenstein et al.'s 2006 sample. Including the photometric-only objects, we estimate a factor of 3 increase in DA white dwarfs. We find that the SDSS spectroscopic follow-up is 44% complete for DA white dwarfs with effective temperature >~ 8000K. We further cross-correlated the SDSS sample with Data Release 8 of the UKIDSS Large Area Survey. The spectral energy distributions of both subsets, with and without SDSS spectroscopy, were fitted with white dwarf models to determine the fraction of DA white dwarfs with low-mass stellar companions or dusty debris discs via the detection of excess near-infrared emission. From the spectroscopic sample we find that 2.0% of white dwarfs have an excess consistent with a brown dwarf type companion, with a firm lower limit of 0.8%. From the white dwarfs with photometry only, we find that 1.8% are candidates for having brown dwarf companions. Similarly, both samples show that ~1% of white dwarfs are candidates for having a dusty debris disc.

description: Writing multithreaded software for multicore computers confronts many developers with the difficulty of finding parallel programming errors. In the past, most parallel debugging techniques have concentrated on finding race conditions due to wrong usage of synchronization constructs. A widely unexplored issue, however, is that a wrong usage of non-parallel programming constructs may also cause wrong parallel application behavior. This paper presents a novel defect-localization technique for multithreaded shared-memory programs that is based on analyzing execution anomalies. Compared to race detectors that report just on wrong synchronization, this method can detect a wider range of defects affecting parallel execution. It works on a condensed representation of the call graphs of multithreaded applications and employs data-mining techniques to locate a method containing a defect. Our results from controlled application experiments show that we found race conditions, but also other programming errors leading to incorrect parallel program behavior. On average, our approach reduced in our benchmark the amount of code to be inspected to just 7.1% of all methods.
Formation of collapsing cores in subcritical magnetic clouds: three-dimensional MHD simulations with ambipolar diffusion

description: We employ the three-dimensional magnetohydrodynamic simulation including ambipolar diffusion to study the gravitationally-driven fragmentation of subcritical molecular clouds, in which the gravitational fragmentation is stabilized as long as magnetic flux-freezing applies. The simulations show that the cores in an initially subcritical cloud generally develop gradually over an ambipolar diffusion time, which is about a few $\times 10^7$ years in a typical molecular cloud. On the other hand, the formation of collapsing cores in subcritical clouds is accelerated by supersonic nonlinear flows. Our parameter study demonstrates that core formation occurs faster as the strength of the initial flow speed in the cloud increases. We found that the core formation time is roughly proportional to the inverse of the square root of the enhanced density created by the supersonic nonlinear flows. The density dependence is similar to that derived in quasistatically contracting magnetically supported clouds, although the core formation conditions are created by the nonlinear flows in our simulations. We have also found that the accelerated formation time is not strongly dependent on the initial strength of the magnetic field if the cloud is highly subcritical. Our simulation shows that the core formation time in our model subcritical clouds is several $\times 10^6$ years, due to the presence of large-scale supersonic flows ($\sim 3$ times sound speed). Once a collapsing core forms, the density, velocity, and magnetic field structure of the core does not strongly depend on the initial strength of the velocity fluctuation. The infall velocities of the cores are subsonic and the magnetic field lines show weak hourglass shapes.

description: Analytical expressions for spectra and wave functions are derived for a Bohr Hamiltonian, describing the collective motion of deformed nuclei, in which the mass is allowed to depend on the nuclear deformation. Solutions are obtained for separable potentials consisting of a Davidson potential in the beta variable, in the cases of gamma-unstable nuclei, axially symmetric prolate deformed nuclei, and triaxial nuclei, implementing the usual approximations in each case. The solution, called the Deformation Dependent Mass (DDM) Davidson model, is achieved by using techniques of supersymmetric quantum mechanics (SUSYQM), involving a deformed shape invariance condition. Spectra and B(E2) transition rates are compared to experimental data. The dependence of the mass on the deformation, dictated by SUSYQM for the potential used, reduces the rate of increase of the moment of inertia with deformation, removing a main drawback of the model.

title: Additive Manufactured Antennas and Novel Frequency Selective Sensors
Creators: name: Njogu, Peter
Publisher: name: University of Kent
Year: 2023

description: The research work carried out and reported in this thesis focuses on the application of additive manufacturing (AM) for the development antennas and novel frequency selective surfaces structures. Various AM techniques such as direct writing (DW), material extrusion, nanoparticle conductive inks are investigated for the fabrication of antennas and FSS based sensors. This research has two parts. The first involves the development of antennas at the microwave and millimetre wave bands using AM techniques. Inkjet printing of nanoparticle silver inks on paper substrate is employed in the fabrication of antennas for an origami robotic bird. This provides an exploration on the practicability of developing foldable antennas which can be integrated on expendable robots using low-cost household inkjet printers. This is followed using Aerosol jet printing in the fabrication of fingernail wearable antennas. The antennas are developed to operate at microwave and millimetre wave bands for potential use in 5G Internet of Things (IoT) or body-centric networks. The second part of the research work involves the development of frequency selective sensors. Trenches have been incorporated on an FSS structure to produce a new concept of liquid sensor. The sensor is fabricated using standard etching techniques and then using FDM method in conjunction with nanoparticle conductive ink. Finally, a new concept displacement sensor using an FSS coupled with a retracting substrate complement is introduced. The displacement sensor is a 3D structure which is conveniently fabricated using AM techniques.

description: We use VLT/FLAMES intermediate resolution (R~6500) spectra of individual red giant branch stars in the near-infrared CaII triplet (CaT) region to investigate the wide-area metallicity properties and internal kinematics of the Sextans dwarf spheroidal galaxy (dSph). Our final sample consists of 174 probable members of Sextans with accurate line-of-sight velocities (+- 2 km/s) and CaT [Fe/H] measurements (+- 0.2 dex). We use the MgI line at 8806.8 Å\, as an empirical discriminator for distinguishing between probable members of the dSph (giant stars) and probable Galactic contaminants (dwarf stars). Sextans shows a similar chemo-dynamical behaviour to other Milky Way dSphs, with its central regions being more metal rich than the outer parts and with the more metal-rich stars displaying colder kinematics than the more metal-poor stars. Hints of a velocity gradient are found along the projected major axis and along an axis at P.A.=191 deg, however a larger and more spatially extended sample may be necessary to pin down the amplitude and direction of this gradient. We detect a cold kinematic substructure at the centre of Sextans, consistent with being the remnant of a disrupted very metal poor stellar cluster. We derive the most extended line-of-sight velocity dispersion profile for Sextans, out to a projected radius of 1.6 deg. From Jeans modelling of the observed line-of-sight velocity dispersion profile we find that this is consistent with both a cored dark matter halo with large core radius and cuspy halo with low concentration. The mass within the last measured point is in the range 2-4 x 10^8 M_sun, giving very large mass-to-light ratios, from 460 to 920 (M/L)_(V,sun).

Computational studies on functional materials

Publisher: name: University of British Columbia
Year: 2021

description: Carbon nanotubes (CNTs) are of great significance due to their almost unlimited potential applications. Transition metal doped CNTs in particular can be developed into small molecule sensors or CNT based catalysis and theoretical studies are important methods to predict their structures and properties. The Project I of this thesis focused on the development of a model that is specifically used for the study of transition metal doped single wall CNT (SWCNT) systems at a reduced computational cost for neutrally charged systems. Longer SWCNT segments of about 20 layers of carbon and terminated by hydrogen or nitrogen atoms with single transition metals doped in exo and endo modes as well as the transition state of the exo-endo transformation were utilized to benchmark our new model. Numerical results show that the new model with a shorter length of SWCNT segment is able to accurately represent geometrical and electronic structures of longer ones based on conventional termination schemes. Computational results further indicate that the transition barrier heights between the exo and endo modes of various metal-doped systems are ranging from 0.1 to 5 eV. Further research work include the study of other elements or metal clusters as dopants, the ionized version of our doped SWCNT systems, as well as to test with other functional methods. Finding the weakest bond within a molecule is crucial for understanding the mechanisms behind chemical reactions and the bond dissociation energy (BDE) is used frequently for locating the weakest bond. However, it requires one to perform tedious calculations of BDEs for all bonds within a molecule. To save time and computational resources, we made attempts to design reasonable yet simple structural indicators to identify weak chemical bonds in Project II. Based on the commonly available structural property indicators for bond strength, such as bond length, the Mulliken interatomic electron number, and the Wiberg bond order, we have created several new bond-strength indicators that can be directly used to efficiently identify almost all weak bonds. In the future, different chemical systems will be analyzed by the new indicators to test their reliabilities.

description: The lifetimes of spin excitations of Mn adsorbates on CuN/Cu(100) are computed from first-principles. The theory is based on a strong-coupling T-matrix approach that evaluates the decay of a spin excitation due to electron-hole pair creation. Using a previously developed theory [Phys. Rev. Lett. {\bf 103}, 176601 (2009) and Phys. Rev. B {\bf 81}, 165423 (2010)], we compute the excitation rates by a tunneling current for all the Mn spin states. A rate equation approach permits us to simulate the experimental results by Loth and co-workers [Nat. Phys. {\bf 6}, 340 (2010)] for large tunnelling currents, taking into account the finite population of excited states. Our simulations give us insight into the spin dynamics, in particular in the way polarized electrons can reveal the existence of an excited state population. In addition, it reveals that the excitation process occurs in a way very different from the deexcitation one. Indeed, while excitation by tunnelling electrons proceeds via the s and p electrons of the adsorbate, deexcitation mainly involves the d electrons.

description: The constant curvature (CC) black holes are higher dimensional generalizations of BTZ black holes. It is known that these black holes have the unusual topology of ${\cal M}_{D-1}\times S^1$, where $D$ is the spacetime dimension and ${\cal M}_{D-1}$ stands for a conformal Minkowski spacetime in $D-1$ dimensions. The unusual topology and time-dependence for the exterior of these black holes cause some difficulties to derive their thermodynamic quantities. In this work, by using globally embedding approach, we obtain the Hawking temperature of the CC black holes. We find that the Hawking temperature takes the same form when using both the static an global coordinates. Also it is identical to the Gibbons-Hawking temperature of the boundary de Sitter spaces of these CC black holes. Employing the same approach, we obtain the Hawking temperature for the counterparts of CC black holes in de Sitter spaces.

description: A pair of bronze greaves – dated to the beginning of the 5th century BC – is preserved at the Antikensammlungen in Munich. On one of them it is possible to read the graffiti epigraph – Denda – that is most probably the anthroponym of their owner. The comparison with a pair of greaves found in a necropolis in the Sikel centre of Montagna di Marzo (Enna), that is generally identified with the ancient city of Herbessus, suggests that the original location of the greaves preserved in Munich can be identified with the same archaeological context. The anthroponym attested by the inscription has been interpreted both as Greek and as Sikel.

description: Carbon foams are hypothetical carbon allotropes that contain graphite-like (sp$^2$ carbon) segments, connected by sp$^3$ carbon atoms, resulting in porous structures. In this work the DFTB (Density Functional based Tight-Binding) method with periodic boundary conditions (PBC) was employed to study energetics, the stability and electronic properties of this unusual class of carbon systems. Concerning the most stable phases of carbon (graphite and diamond), foams show high structural stability at very low mass density. The electronic band structure and electronic DOS (density of states) of foams indicate a similar size dependence as carbon nanotubes. The calculated bulk moduli are in the range between that of graphite (5.5 GPa) and diamond (514 GPa). These structures may represent novel stable carbon modifications with sp$^2$+sp$^3$ hybridization.

Die Inhibition von GSK-3 löst Apoptose in Tumorzellen aus und hemmt das Tumorwachstum im Tiermodell
Creators: name: Marinescu, Gabriela
Publisher: name: Karlsruhe
Year: 2008

description: Die Glykogen Synthase Kinase-3 (GSK-3) ist eine Serin/Threonin Kinase, die eine zentrale Rolle in vielen Signalwegen (Insulinsynthese, Wnt-Signalweg u.s.w.) spielt. In meiner Arbeit konnte ich zeigen, dass die Inhibition von GSK-3, Apoptose in p53- positiven und -negativen Tumorzellen induzierte. Die Inaktivierung von GSK-3 führt unter anderem zur Stabilisierung des p53-Proteins, das als Transkriptionsfaktor für antiproliferative und pro-apoptotische Gene einen wesentlichen Einfluss auf die Zellproliferation ausübt.
In proliferierenden Zellen ist die p53-Proteinmenge niedrig und das Protein inaktiv. Wird die Menge des p53-Proteins erhöht, indem zum Beispiel sein Abbau verhindert wird, so werden die p53-abhängigen Zielgene transkribiert und Zellzyklusarrest oder Apoptose ausgelöst.
Da die Inaktivierung von GSK-3 in vorausgehenden Experimenten zur Mengenzunahme von transkriptionell aktivem p53 führte, lag die Hypothese nahe, dass die Inhibition von GSK-3 die Zellproliferation inhibieren könnte.
Die Behandlung unterschiedlicher p53-positiver und -negativer Zelllinien mit den gängigen GSK-3-Inhibitoren Lithiumchlorid oder Alsterpaullon hat eine entscheidende Wirkung auf die Zellproliferation, da sie den programmierten Zelltod in Tumorzellen einleiten.
In Anwesenheit von LiCl zeigten die Zellen die typischen Apoptosemerkmale wie Caspase-3-Aktivierung, PARP-Spaltung und DNS-Fragmentierung. Eine eindeutige p53-Abhängigkeit konnte ich in meinen Experimenten nicht feststellen, obwohl die Caspase-3-, PARP-Aktivierung und DNS-Fragmentierung in den p53-negativen Zellen schwächer war. Das Ausschalten der beiden Isoformen GSK-3α und -β-durch Transfektion spezifischer siRNA-Sequenzen führte ebenfalls zur Aktivierung von Caspase-3, was mich schlussfolgern ließ, dass die Inhibition dieser Kinase die Apoptose hervorruft.
Um dieses Ergebnis auch in vivo nachweisen zu können, habe ich syngene Ratten mit LiCl und NaCl vorbehandelt, mit MT450-Mammakarzinomzellen gespritzt, um die Tumorentwicklung zu stimulieren, und anschließend das Tumorwachstum über mehrere Wochen verfolgt. Die tägliche Behandlung der Tiere mit LiCl hat ihr Tumorwachstum stark beeinträchtigt und löste Apoptose in den Tumorzellen aus. Die anschließenden histologischen Untersuchungen der Tumore zeigten, dass die mit LiCl behandelten Ratten, im Vergleich zu den mit NaCl behandelten beziehungsweise den Kontrolltieren, eine erhöhte Apoptoserate aufwiesen.
Diese Reaktion der Tumorzellen lässt hoffen, dass die Inhibition von GSK-3 eines Tages in der Tumortherapie eingesetzt werden kann, um selektiv die malignen Zellen in einem Organismus zu töten.

description: The spectra of B-type and early A-type stars show numerous unidentified lines in the whole optical range, especially in the 5100 - 5400 A interval. Because Fe II transitions to high energy levels should be observed in this region, we used semiempirical predicted wavelengths and gf-values of Fe II to identify unknown lines. Semiempirical line data for Fe II computed by Kurucz are used to synthesize the spectrum of the slow-rotating, Fe-overabundant CP star HR 6000. We determined a total of 109 new 4f levels for Fe II with energies ranging from 122324 cm^-1 to 128110 cm^-1. They belong to the Fe II subconfigurations 3d^6(^3P)4f (10 levels), 3d^6(^3H)4f (36 levels), 3d^6(^3F)4f (37 levels), and 3d^6(^3G)4f (26 levels). We also found 14 even levels from 4d (3 levels), 5d (7 levels), and 6d (4 levels) configurations. The new levels have allowed us to identify more than 50% of the previously unidentified lines of HR 6000 in the wavelength region 3800-8000 A. Tables listing the new energy levels are given in the paper; tables listing the spectral lines with loggf>/=-1.5 that are transitions to the 4f energy levels are given in the Online Material. These new levels produce 18000 lines throughout the spectrum from the ultraviolet to the infrared.

description: The horos was reported to Hiller von Gaertringer in June 1930 by Franz Gabriel Welter, engaged in excavations during the 1920s in the areas of Hyria and Livadi (Naxos). The document is remarkable for the definition of the concept of apotimema, the estimated value of properties given as security for the lease of property of a subject protected by the eponymous archon (orphans, widows and epikleroi). In this specific case, we have a pupillary apotimema: lands and the house, with the tiled roof, valued and placed as apotimema for the goods capitalised by the epitropos of Epiphron’s children. The capital loaned is 3,500 drachmas and the children would have obtained 400 drachmas as annual interest. Among the land pledged to guarantee the sum, the possessions in the localities of Elaious and Melanes are also mentioned, the latter’s toponym still in use for the village that is located in the north-central area of the island of Nassia.

Thymos and Metis in Medea by Euripides
Creators: name: Lentini, Giuseppe
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2020

description:

This paper argues that Euripides’ Medea is characterised by μῆτις (cunning intelligence), and reveals significant analogies with Homer’s Odysseus, the πολύμητις hero: the plot of the tragedy itself seems to be modelled on the Cyclops’ adventure in the Odyssey; also, Medea’s tendency to deliberative monologues (as many as five in the drama) is to be considered a defining element of her μῆτις. This aspect of Medea’s character should be weighed in relation to her ‘spirit’, that is, θυμός (rage), especially since θυμός and μῆτις are seen as more or less polar opposites in the Homeric poems. Medea’s monologues in the tragedy (including her ‘great monologue’ at ll. 1021-80) are then analyzed on the basis of such assumptions.

Characterizing canonical and non-canonical roles of telomerase reverse transcriptase in transformed human cells and cancer
Creators: name: Thompson, Connor Alexander
Publisher: name: University of British Columbia
Year: 2017

description: Telomerase is the ribonucleoprotein reverse transcriptase that catalyzes the synthesis of TTAGGG nucleotide repeats at the ends of linear chromosomes, contributing to proper telomeric structure and cap formation. Most human somatic cells have low or undetectable telomerase expression. In contrast, telomerase overexpression is found in over 85% of human cancers allowing cancer cells to replicate indefinitely. Telomerase inhibition by GRN163L (Imetelstat) has previously been observed to potentiate genotoxic stress in a cell-cycle (S/G2) specific manner, through an unknown mechanism. We hypothesized that GRN163L treatment alters cell-cycle kinetics and that this effect depends upon active signaling through ataxia telangiectasia mutated (ATM). Here we tested the effects of combining GRN163L and the topoisomerase II inhibitor etoposide, together with pharmacological ATM inhibition on MCF-7 breast cancer cells, to assess dependence of telomerase’s cyto-protective function on this DNA-damage repair transducer. Additive increased cytotoxicity and cell-cycle profile alterations depended upon the order of treatment addition. Investigating possible causes of these cell-cycle distribution changes we observed that telomerase inhibition alone induces γH2AX DNA-damage foci in a subset of telomerase-positive cells but not telomerase-negative primary human fibroblasts. Additional FACS and immunocytochemistry experiments indicate that GRN163L-treated cells were reversibly stalled but not arrested at G2/M. Our results suggest that treatment with GRN163L sensitizes telomerase-positive cells to cell-cycle specific DNA-damaging agents through the engagement of an ATM-dependent DNA-damage signal, which may represent a separate mechanism by which telomerase inhibition could affect DNA repair homeostasis in telomerase-positive cancer cells. In addition to its telomere-maintenance function telomerase has recently been reported to participate in non-canonical activities such as protection from DNA-damaging agents, apoptosis, cellular proliferation rate, and resistance to oxidative stress. In a separate study, we hypothesized that overexpression of telomerase in transformed human cells would increase their survival following exposure to DNA-damaging agents. Our results indicate that telomerase expression protects cells from a variety of DNA-damaging drugs by improving the kinetics of DNA-repair. Telomerase expression also allows surviving cells to tolerate increased levels of chromosomal instability following drug exposure. This work has implications on improving the design of future telomerase inhibition strategies to also target non-canonical effects of this enzyme.
Memorial from Delphi for Archon of Pella

description: The Delphic monument dedicated to Archon, general of Alexander, bears three inscriptions. The epigram b (prior to 333 B.C.) celebrates Archon’s victories in the Pythian and Isthmic agons. The decree c (333-332 B.C.) grants Archon and his family a series of privileges. The epigram a, following Archon’s death (321 B.C.), serves as a dedication of the statues of Archon’s family members, now lost. The inscriptions confirm what is already known from ancient historiography (his association with Alexander), and provide otherwise unknown information (family ties, his participation in pan-Hellenic games, relations with the city of Delphi).

Assessment of the biodistribution of aluminum-based vaccine adjuvants using ¹¹¹/¹¹⁵In-AlO(OH)
Creators: name: Esposito, Tullio Vito Francesco
Publisher: name: University of British Columbia
Year: 2018

description: Aluminum-based adjuvants are found in a wide range of non-living vaccines to enhances antibody-mediated immune responses. Alhydrogel is one of the most common aluminum-based adjuvants and consists of 1-12 μm clusters of loosely aggregated aluminum oxyhydroxide (AlO(OH)) nanoparticles. Despite widespread use since in 1930s, the biodistribution of this adjuvant is poorly understood. The current assumption within the field is that AlO(OH) particles remain at the site of injection and slowly dissolve over time. However, rare neurological and muscle adverse effects, such as macrophagic myofasciitis, are thought to be due to the bio-persistence of the adjuvant at the site of injection and the distribution of AlO(OH) nanoparticles throughout the body. The objective of this thesis was to examine if component nanoparticles of Alhydrogel distribute following administration. In order the test this hypothesis, traceable forms of AlO(OH) were synthesized by doping the adjuvant’s crystal structure with different indium isotopes. Various physical, morphological and functional assessments showed that the doped adjuvant closely matched commercial Alhydrogel. Using a radioactive version of the tracer, ¹¹¹In-AlO(OH), the biodistribution of the adjuvant was assessed using serial SPECT/CT imaging. Approximately 20% of the tracer was released from the site of injection over 15 days and could be found in organs like the draining lymph nodes and liver. A novel application of mass cytometry was used to examine the kinetics and cellular distribution of ¹¹⁵In-AlO(OH) particles within the draining lymph nodes; the adjuvant appeared at this site within 1 day and reached peak levels 15 days post-injection. The adjuvant was sequestered into antigen presenting cells and induced the up-regulation of maturation markers in adjuvant-positive dendritic cells within the draining lymph node. Finally, electron microscopy coupled with atomic mapping confirmed the presence of Alhydrogel component nanoparticles in the draining lymph node and liver. This thesis presents the most detailed assessment to date of the biodistribution of aluminum-based adjuvants. Understanding Alhydrogel’s biodistribution can help shed light on the adjuvant’s immunostimulatory mechanisms and adverse events. Lessons learnt from one of the world oldest adjuvants can be applied to the design of next generation of immunopotentiators.

description: We consider the possible anomaly free Abelian discrete symmetries of the MSSM that forbid the mu-term at perturbative order. Allowing for anomaly cancellation via the Green-Schwarz mechanism we identify discrete R-symmetries as the only possibility and prove that there is a unique Z_4^R symmetry that commutes with SO(10). We argue that non-perturbative effects will generate a mu-term of electroweak order thus solving the mu-problem. The non-perturbative effects break the Z_4^R symmetry leaving an exact Z_2 matter parity. As a result dimension four baryon- and lepton-number violating operators are absent while, at the non-perturbative level, dimension five baryon- and lepton-number violating operators get induced but are highly suppressed so that the nucleon decay rate is well within present bounds.

description:

This essay focuses on the unpublished comparison between Heracles’ banquet in the fourth episode of the Alcestis and the Orestes’ one, in the second episode of Iphigenia in Tauris. For the first time, these scenes will be also juxtaposed to the Choes, the feast celebrated during the Anthesteria, in which laughter and pain coexist. The common feature between banquets and feasting is the value of xenia.

The near-infrared reflected spectrum of source I in Orion-KL

description: Source I in the Orion-KL nebula is believed to be the nearest example of a massive star still in the main accretion phase. It is thus one of the best cases for studying the properties of massive protostars to constrain high-mass star formation theories. Near-infrared radiation from source I escapes through the cavity opened by the OMC1 outflow and is scattered by dust towards our line of sight. The reflected spectrum offers a unique possibility of observing the emission from the innermost regions of the system and probing the nature of source I and its immediate surroundings. We obtained moderately high spectral-resolution (R~9000) observations of the near-infrared diffuse emission in several locations around source I/Orion-KL. We observed a widespread rich absorption line spectrum that we compare with cool stellar photospheres and protostellar accretion disk models. The spectrum is broadly similar to strongly veiled, cool, low-gravity stellar photospheres in the range Teff~3500-4500 K, luminosity class I-III. An exact match explaining all features has not been found, and a plausible explanation is that a range of different temperatures contribute to the observed absorption spectrum. The 1D velocity dispersions implied by the absorption spectra, sigma~30 km/s, can be explained by the emission from a disk around a massive, mstar~10 Msun, protostar that is accreting at a high rate, mdot~3x10^{-3} Msun/yr. Our observations suggest that the near-infrared reflection spectrum observed in the Orion-KL region is produced close to source I and scattered to our line of sight in the OMC1 outflow cavity. The spectrum allows us to exclude source I being a very large, massive protostar rotating at breakup speed. We suggest that the absorption spectrum is produced in a disk surrounding a ~10 Msun protostar, accreting from its disk at a high rate of a few 10^{-3} Msun/yr.

description: We conducted the astrometry of H2O masers in the Galactic star-forming region Onsala 1 (ON1) with VLBI Exploration of Radio Astrometry (VERA). We measured a trigonometric parallax of 0.404+/-0.017 mas, corresponding to a distance of 2.47+/-0.11 kpc. ON1 is appeared to be located near the tangent point at the Galactic longitude of 69.54 deg. We estimate the angular velocity of the Galactic rotation at Sun, the ratio of the distance from Sun to the Galactic center and the Galactic rotation velocity at Sun, to be 28.7+/-1.3 km/s/kpc using the measured distance and proper motion of ON1. This value is larger than the IAU recommended value of 25.9 km/s/kpc, but consistent with other results recently obtained with the VLBI technique.
