description: We calculate the primordial spectrum of scalar perturbations of the 3-form inflation and we find that the curvature perturbations decay at late times. As as result, although a non-minimally coupled massive 3-form field may drive inflation at early times, it should be assisted by other fields in order to reproduce the observed temperature fluctuations of the CMB sky.

description: Author order: Waight, Yang, Yuan, Messing, Roberts, Stewart, Tucker. Bias in large language models is particularly concerning because of the capacity of generative AI to translate these biases into seemingly objective text (Benjamin, 2020). This project considers a special case of AI bias: propaganda bias. Governments with control over the information environment are able to disseminate propagandist texts through print and digital news, which then can potentially be utilized as training data for LLMs (Yang and Roberts, 2023). These models can then potentially reproduce propaganda in their outputs.

We design our study based on Metaxa et al. (2022) and Metaxa et al. (2024), prompting a sociotechnical system with queries that vary along the dimension of interest and having human coders evaluate the results. We conduct an audit of GPT 3.5 chat, a commonly used generative AI model, by comparing the completions returned by GPT 3.5 when prompted in Chinese vs. English. We expect that GPT completions are more likely to be favorable to mainland China institutions, leaders, and systems when we prompt in Chinese rather than English. We expect this because we anticipate that large language models like GPT and Llama will draw more on their Chinese language training texts when prompted in Chinese about China-related topics. These training texts will be more likely to have their contents affected by propaganda interventions from the Chinese propaganda apparatus than English language texts. We do not expect the same degree of learning to occur from propaganda affected Chinese language texts for completions from English prompts or for completions from Chinese or English prompts about non-China related topics.

description: We have performed a systematic first-principles investigation to calculate the electronic structures, mechanical properties, and phonon dispersion curves of NpO$_{2}$. The local density approximation$+U$ and the generalized gradient approximation$+U$ formalisms have been used to account for the strong on-site Coulomb repulsion among the localized Np $5f$ electrons. By choosing the Hubbard \emph{U} parameter around 4 eV, the orbital occupancy characters of Np 5\emph{f} and O 2\emph{p} are in good agreement with recent experiments [J. Nucl. Mater. \textbf{389}, 470 (2009)]. Comparing with our previous study of ThO$_{2}$, we note that stronger covalency exists in NpO$_{2}$ due to the more localization behavior of 5\emph{f} electrons of Np in line with the localization-delocalization trend exhibited by the actinides series.

Long range Coulomb interaction in bilayer graphene

description: We report on our studies of interacting electrons in bilayer graphene in a magnetic field. We demonstrate that the long range Coulomb interactions between electrons in this material are highly important and account for the band asymmetry in recent optical magneto-absorption experiments. We show that in the unbiased bilayer (where both layers are at the same electrostatic potential), the interactions can cause mixing of Landau levels in moderate magnetic fields. For the biased bilayer (when the two layers are at different potentials), we demonstrate that the interactions are responsible for a change in the total spin of the ground state for half-filled Landau levels in the valence band.

description: Using Noether's procedure we present a complete solution for the trilinear interactions of arbitrary spins $s_{1},s_{2}, s_{3}$ in a flat background, and discuss the possibility to enlarge this construction to higher order interactions in the gauge field. Some classification theorems of the cubic (self)interaction with different numbers of derivatives and depending on relations between the spins are presented. Finally the expansion of a general spin $s$ gauge transformation into powers of the field and the related closure of the gauge algebra in the general case are discussed.

description: We consider the high energy limit of the colour ordered one-loop five-gluon amplitude in the planar maximally supersymmetric N=4 Yang-Mills theory in the multi-Regge kinematics where all of the gluons are strongly ordered in rapidity. We apply the calculation of the one-loop pentagon in D=6-2 eps performed in a companion paper to compute the one-loop five-gluon amplitude through to O(eps^2). Using the factorisation properties of the amplitude in the high-energy limit, we extract the one-loop gluon-production vertex to the same accuracy, and, by exploiting the iterative structure of the gluon-production vertex implied by the BDS ansatz, we perform the first computation of the two-loop gluon-production vertex up to and including finite terms.

The OPTX Project III: X-ray versus Optical Spectral Type for AGNs

description: We compare the optical spectral types with the X-ray spectral properties for a uniformly selected (sources with fluxes greater than the 3 sigma level and above a flux limit of f_2-8 keV > 3.5x10^-15 erg/cm2/s), highly spectroscopically complete (>80% for f_2-8 keV > 10^-14 erg/cm2/s and >60% below) 2-8 keV X-ray sample observed in three Chandra fields (CLANS, CLASXS, and the CDF-N) that cover ~1.2 deg^2. For our sample of 645 spectroscopically observed sources, we confirm that there is significant overlap of the X-ray spectral properties, as determined by the effective photon indices, Geff, obtained from the ratios of the 0.5-2 keV to 2-8 keV counts, for the different optical spectral types. For example, of the broad-line AGNs (non-broad-line AGNs), 20% +/- 3% (33% +/- 4%) have Geff<1.2 (Geff > 1.2). Thus, one cannot use the X-ray spectral classifications and the optical spectral classifications equivalently. Since it is not understood how X-ray and optical classifications relate to the obscuration of the central engine, we strongly advise against a mixed classification scheme, as it can only complicate the interpretation of X-ray AGN samples. We confirm the dependence of optical spectral type on X-ray luminosity, and for z<1, we find a similar luminosity dependence of Geff. However, this dependence breaks down at higher redshifts due to the highly redshift-dependent nature of Geff. We therefore also caution that any classification scheme which depends on Geff is likely to suffer from serious redshift bias.

An improved analytical description of inspiralling and coalescing black-hole binaries

description: We present an analytical formalism, within the Effective-One-Body framework, which predicts gravitational-wave signals from inspiralling and coalescing black-hole binaries that agree, within numerical errors, with the results of the currently most accurate numerical relativity simulations for several different mass ratios. In the equal-mass case, the gravitational wave energy flux predicted by our formalism agrees, within numerical errors, with the most accurate numerical-relativity energy flux. We think that our formalism opens a realistic possibility of constructing a sufficiently accurate, large bank of gravitational wave templates, as needed both for detection and data analysis of (non spinning) coalescing binary black holes.

description: Faraday Rotation Measure (RM) Synthesis, as a method for analyzing multi-channel observations of polarized radio emission to investigate galactic magnetic fields structures, requires the definition of complex polarized intensity in the range of the negative lambda square. We introduce a simple method for continuation of the observed complex polarized intensity into this domain using symmetry arguments. The method is suggested in context of magnetic field recognition in galactic disks where the magnetic field is supposed to have a maximum in the equatorial plane. The method is quite simple when applied to a single Faraday-rotating structure on the line of sight. Recognition of several structures on the same line of sight requires a more sophisticated technique. We also introduce a wavelet-based algorithm which allows us to consider a set of isolated structures. The method essentially improves the possibilities for reconstruction of complicated Faraday structures using the capabilities of modern radio telescopes.

Excitation dependence of resonance line self-broadening at different atomic densities

description: We study the dipole-dipole spectral broadening of a resonance line at high atomic densities when the self-broadening dominates. The selective reflection spectrum of a weak probe beam from the interface of the cell window and rubidium vapor are recorded in the presence of a far-detuned pump beam. The excitation due to the pump reduces the self-broadening. We found that the self-broadening reduction dependence on the pump power is atomic density independent. These results provide experimental evidence for the disordered exciton based theory of self-broadening, and can be useful for the description of the interaction of a strong optical field with a dense resonance medium.

title: Auswertung der Umfrage „Nutzerforschung in wissenschaftlichen Bibliotheken - Regionalnutzende an der ULB Darmstadt“
Creators: name: Grund, Heiko

description: Dienstleistungs- und Zielgruppenorientierung spielen im Alltag wissenschaftlicher Bibliotheken mittlerweile eine entscheidende Rolle. Im Gegensatz zu Hochschulbibliotheken, bei denen sich die Zielgruppen relativ klar definieren lassen, ist das Umfeld der Nutzer:innen von Regional- und Landesbibliotheken sehr heterogen. Die ULB Darmstadt erfüllt hierbei eine klassische Doppelaufgabe: Als Hochschulbibliothek ist sie für die Medienversorgung aller Angehörigen der TU Darmstadt zuständig und in ihrer Funktion als Landesbibliothek zugleich auch Ansprechpartnerin für alle interessierten Nutzer:innen aus der Region Südhessen. Während die Bedürfnisse der Studierenden und Beschäftigten der TU an der ULB bereits mehrfach durch Befragungen erhoben wurden, waren die Wünsche und Bedürfnisse der Nutzer:innen aus der Region lange weitgehend unbekannt. Neben der Heterogenität stellte die schwierige Erreichbarkeit dieser Zielgruppe eine besondere Herausforderung dar. Gemeinsam mit der Hochschule Darmstadt führte die ULB im Sommersemester 2022 schließlich ein Forschungsprojekt durch, um mittels Onlinebefragung die folgenden Fragen bzgl. (potentiellen) Nutzer:innen aus der Region zu beantworten: Welche Veranstaltungs- und Lernangebote sind von Interesse? Wann, wo und wie sollten sie vermittelt und beworben werden? Mit welchen Einrichtungen sollte die ULB in diesem Bereich kooperieren? Die Antworten hierauf sind in dieser ausführlichen Auswertung der Befragung zu finden.

description: We have recently completed a 64-night spectroscopic monitoring campaign at the Lick Observatory 3-m Shane telescope with the aim of measuring the masses of the black holes in 12 nearby (z < 0.05) Seyfert 1 galaxies with expected masses in the range ~10^6-10^7 M_sun and also the well-studied nearby active galactic nucleus (AGN) NGC 5548. Nine of the objects in the sample (including NGC 5548) showed optical variability of sufficient strength during the monitoring campaign to allow for a time lag to be measured between the continuum fluctuations and the response to these fluctuations in the broad Hbeta emission. We present here the light curves for the objects in this sample and the subsequent Hbeta time lags for the nine objects where these measurements were possible. The Hbeta lag time is directly related to the size of the broad-line region, and by combining the lag time with the measured width of the Hbeta emission line in the variable part of the spectrum, we determine the virial mass of the central supermassive black hole in these nine AGNs. The absolute calibration of the black hole masses is based on the normalization derived by Onken et al. We also examine the time lag response as a function of velocity across the Hbeta line profile for six of the AGNs. The analysis of four leads to ambiguous results with relatively flat time lags as a function of velocity. However, SBS 1116+583A exhibits a symmetric time lag response around the line center reminiscent of simple models for circularly orbiting broad-line region (BLR) clouds, and Arp 151 shows an asymmetric profile that is most easily explained by a simple gravitational infall model. Further investigation will be necessary to fully understand the constraints placed on physical models of the BLR by the velocity-resolved response in these objects.

Sustaining Digital Scholarship: keeping research data alive

description: The need to sustain data and outputs from research projects well beyond their initial grant-funded period is commonplace within academia, particularly so within the Humanities. We often find that these semi-active or warm data collections have value and require care beyond the life of the original hosting, system, or platform they were conceived upon. With the increasing demand to make data more open, and research funding bodies increasing requirements and time periods for which research data must remain available, institutions need to be ready to offer researchers the tools and platforms to comply. Compliance is one lens through which to view this particular challenge. Yet we believe that institutions should and can be motivated to sustain data by celebrating the research they develop, and through reaping the continued scholarly benefits and impact gained through research data being hosted and shared for as long as possible. Our poster present practical insights into the methods employed at the University of Oxford to support digital humanities scholars (and others) safeguard their digital legacies. We concentrate and focus on 3 areas of ‘People’, ‘Process’ & ‘Technology’ to highlight how the Sustainable Digital Scholarship (SDS) service at Oxford is helping researchers and their projects secure the long-term future of their research data outputs.

description: We present evidence for the first observation of electromagnetically bound $π^\pm K^\mp$-pairs ($πK$-atoms) with the DIRAC experiment at the CERN-PS. The $πK$-atoms are produced by the 24 GeV/c proton beam in a thin Pt-target and the $π^\pm$ and $K^\mp$-mesons from the atom dissociation are analyzed in a two-arm magnetic spectrometer. The observed enhancement at low relative momentum corresponds to the production of 173 $\pm$ 54 $πK$-atoms. The mean life of $πK$-atoms is related to the s-wave $πK$-scattering lengths, the measurement of which is the goal of the experiment. From these first data we derive a lower limit for the mean life of 0.8 fs at 90% confidence level.

description: Hyper-velocity stars (HVSs) were first predicted by theory to be the result of the tidal disruption of a binary system by a super-massive black hole (SMBH) that accelerates one component to beyond the Galactic escape velocity (the Hills mechanism). Because the Galactic centre hosts such a SMBH it is the suggested place of origin for HVSs. However, the SMBH paradigm has been challenged recently by the young HVS HD271791 because its kinematics point to a birthplace in the metal-poor rim of the Galactic disc. Here we report the atmosphere of HD271791 to indeed show a sub-solar iron abundance along with an enhancement of the alpha-elements, indicating capture of nucleosynthesis products from a supernova or a more energetic hypernova. This implies that HD271791 is the surviving secondary of a massive binary system disrupted in a supernova explosion. No such run-away star has ever been found to exceed the Galactic escape velocity, hence HD271791 is the first hyper-runaway star. Such a run-away scenario is an alternative to the Hills mechanism for the acceleration of some HVSs with moderate velocities. The observed chemical composition of HD271791 puts invaluable observational constraints on nucleosynthesis in a supernova from the core-collapse of a very massive star (M_ZAMS >= 55 M_Sun), which may be observed as a gamma-ray burst of the long-duration/soft-spectrum type.
