Experiments on Generalizability of BERTopic on Multi-Domain Short Text
Muriël de Groot, Mohammad Aliannejadi, Marcel R. Haas
Topic modeling is widely used for analytically evaluating large collections of textual data. One of the most popular topic techniques is Latent Dirichlet Allocation (LDA), which is…
Stellar Signatures of AGN Jet Triggered Star Formation
Zachary Dugan, Sarah Bryan, Volker Gaibler +2
To investigate feedback between relativistic jets emanating from Active Galactic Nuclei (AGN) and the stellar population of the host galaxy, we analyze the long-term evolution of t…
Damped Lyα Absorption Systems in Semi-Analytic Models with Multiphase Gas
Michael Berry, Rachel S. Somerville, Marcel R. Haas +4
We investigate the properties of damped Lyα absorption systems (DLAs) in semi-analytic models of galaxy formation, including partitioning of cold gas in galactic discs into atomic,…
Physical properties of simulated galaxy populations at z=2 - II. Effects of cosmology, reionization and ISM physics
Marcel R. Haas, Joop Schaye, C. M. Booth +4
We use hydrodynamical simulations from the OWLS project to investigate the dependence of the physical properties of galaxy populations at redshift 2 on the assumed star formation l…
Physical properties of simulated galaxy populations at z=2 - I. Effect of metal-line cooling and feedback from star formation and AGN
Marcel R. Haas, Joop Schaye, C. M. Booth +4
We use hydrodynamical simulations from the OWLS project to investigate the dependence of the physical properties of galaxy populations at redshift 2 on metal-line cooling and feedb…
Jet interactions with a giant molecular cloud in the Galactic centre and ejection of hypervelocity stars
Joseph Silk, Vincenzo Antonuccio-Delogu, Yohan Dubois +4
The hypervelocity OB stars in the Milky Way Galaxy were ejected from the central regions some 10-100 million years ago. We argue that these stars, {as well as many more abundant bo…
