Search for Axion-Like Particles from Nearby Pre-Supernova Stars
Saurabh Mittal, Thomas Siegert, Francesca Calore +7
Axion-like particles (ALPs) are hypothetical pseudoscalar bosons that arise in many extensions of the Standard Model and are well-motivated dark matter candidates. Nearby massive s…

Unification of Gravities with GUTs
Danai Roumelioti, Stelios Stefas, George Zoupanos
Within the gauge-theoretic approach of gravity, the gauging of an enlarged symmetry of the tangent space in four dimensions allows gravity to be unified with internal interactions.…
eROSITA-RU Tidal Disruption Events with Keck-I/LRIS: Sample Selection, Optical Properties, and Host Galaxy Demographics

We select seventy tidal disruption event (TDE) candidates among X-ray transients discovered during the eROSITA all-sky surveys in the Eastern Galactic hemisphere between December 2…
Rapid sinking and efficient mergers of supermassive black holes in compact high-redshift galaxies
Atte Keitaanranta, Peter H. Johansson, Alexander Rawlings +5
We present a cosmological zoom-in simulation targeting the high redshift compact progenitor phase of massive galaxies, with the most massive galaxy reaching a stellar mass of $M_{\…
Perturbative limits on axion-SU(2) gauge dynamics during inflation from the energy density of spin-2 particles
Koji Ishiwata, Eiichiro Komatsu
We investigate the conditions under which the perturbative treatment of the backreaction of spin-2 particles on the dynamics of an axion-SU(2) gauge field system breaks down during…
Characterization of debris disks observed with SPHERE
N. Engler, J. Milli, N. Pawellek +33
This study aims to characterize debris disks observed with SPHERE across multiple programs, with the goal of identifying systematic trends in disk morphology, dust mass, and grain…
Tighter constraints on the atmosphere of GJ 436 b from combined high-resolution CARMENES and CRIRES observations
A. Peláez-Torres, A. Sánchez-López, L. Nortmann +23
We aim to study the atmospheric properties of the warm Neptune GJ 436 b by combining a set of five transit events observed with the CARMENES spectrograph with one transit from CRIR…
The evolutionary history of ultra-compact accreting binaries. I. Chemical abundances and formation channel of the eclipsing AM CVn system ZTF J225237.05-051917.4 from HST spectroscopy
W. Yu, A. F. Pala, T. Kupfer +33
AM Canum Venaticorum (AM CVn) stars are ultra-compact binary systems composed of a white dwarf (WD) primary accreting from a H-deficient donor. They are important as potential prog…
The effect of baryons on the positions and velocities of satellite galaxies in the MTNG simulation
Sergio Contreras, Raul E. Angulo, Sownak Bose +5
Mock galaxy catalogues are often constructed from dark-matter-only simulations based on the galaxy-halo connection. Although modern mocks can reproduce galaxy clustering to some ex…
Probing jet base emission of M87* with the 2021 Event Horizon Telescope observations
