X-ray Characterization of Galaxy Groups and Hickson Groups in COSMOS-Web to z~3.8 I. X-ray Luminosity Function Evolution
Ghassem Gozaliasl, Günther Hasinger, Gavin Leroy +35
Galaxy groups are the dominant halo environment in the Universe and a sensitive laboratory for feedback and gas-cycling physics, yet a uniform, intermediate-redshift X-ray characte…
Forged by Feedback: Stellar Properties of Brightest Group Galaxies in Cosmological Simulations
Ruxin Barré, Arif Babul, Ghassem Gozaliasl +7
We investigate how different galaxy formation models impact the stellar properties of brightest group galaxies (BGGs) in four cosmological simulations: ROMULUS, SIMBA, SIMBA-C, and…
Universal Structure of Turbulent Radiative Mixing Layers
Prateek Sharma, Arnav Kumar, Dipayan Datta +3
Turbulent radiative mixing layers (TRMLs), where shear-driven turbulence between dense and diffuse gas produces rapidly cooling intermediate-temperature gas, are ubiquitous in the…
COSMOS Web: Morphological quenching and size-mass evolution of brightest group galaxies from z = 3.7
Ghassem Gozaliasl, Lilan Yang, Jeyhan Kartaltepe +47
We present a comprehensive study of the structural evolution of Brightest Group Galaxies (BGGs) from redshift to using the \textit{James Webb Space Telesc…
The COSMOS-Web deep galaxy group catalog up to
Greta Toni, Ghassem Gozaliasl, Matteo Maturi +41
Galaxy groups with and up to a few tens of members are the most common galaxy environment, marking the transition between field and massive clu…
Weak Lensing by Large-Scale Structure with the FIRST Radio Survey
A. Refregier, S. T. Brown, M. Kamionkowski +5
The coherent image distortions induced by weak gravitational lensing can be used to measure the power spectrum of density inhomogeneities in the universe. We present our on-going e…
