What's Missing in AGN Feedback? Lessons learnt from Magneticum, IllustrisTNG and Simba
D. T. Mazengo, P. Popesso, I. Marini +20
Accurately balancing gas reservoirs, star formation, and feedback across cosmic time remains a central challenge for galaxy formation models in modern hydrodynamical simulations. W…
A Decade to Map the Diffuse Universe: FRB-QSO Pairs with HST/COS Spectroscopy
Jessica Werk, Matthew McQuinn, J. Xavier Prochaska +16
Jointly analyzing the sightlines of arcsecond-localized fast radio bursts (FRBs) and UV-bright quasars (QSOs) nearby in projection has the potential to provide strong constraints o…
Multimodal Transformer Based Generic Mixture Density Network for Scattering Timescale Estimation of Fast Radio Bursts
Bikash Kharel, Emmanuel Fonseca, Srinjoy Das +5
The discovery rate of fast radio bursts (FRBs) continues to increase with the advent of new radio facilities and yet extracting their astrophysical parameters such as scattering ti…
Discovery of 30 Repeating Fast Radio Burst Sources and Uniform Population Statistics of 80 Repeating Sources from CHIME/FRB
Amanda M. Cook, Kaitlyn Shin, Ziggy Pleunis +44
We present 30 newly discovered repeating fast radio burst (FRB) sources from the second catalog of bursts detected by the FRB backend on the Canadian Hydrogen Intensity Mapping Exp…
Constraining Gas Mass Fractions in Galaxy Groups and Clusters with the First CHIME/FRB Outrigger
Adam E. Lanman, Sunil Simha, Kiyoshi W. Masui +16
In recent years, localized fast radio bursts (FRBs) have emerged as a powerful tool to study the structure of the baryonic matter in the universe. Their dispersion measures (DMs) s…
Constraining the mass of the M31 ionized baryon Halo using CHIME/FRB Catalog 2
Lordrick A. Kahinga, J. Xavier Prochaska, Sunil Simha +21
The circumgalactic medium (CGM) surrounding galaxies is believed to be a significant reservoir of baryons, yet its total mass remains poorly constrained. We present a novel approac…
