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…
Asymptotic behaviour of galactic small-scale dynamos at modest magnetic Prandtl number
Frederick A. Gent, Mordecai-Mark Mac Low, Maarit J. Korpi-Lagg +2
Magnetic fields are critical at many scales to galactic dynamics and structure, including multiphase pressure balance, dust processing, and star formation. Dynamo action determines…
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…
COSMOS-Web: Estimating Physical Parameters of Galaxies Using Self-Organizing Maps
Fatemeh Abedini, Ghassem Gozaliasl, Akram Hasani Zonoozi +38
The COSMOS-Web survey, with its unparalleled combination of multiband data, notably, near-infrared imaging from JWST's NIRCam (F115W, F150W, F277W, and F444W), provides a transform…
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…
Computational approaches to modeling dynamos in galaxies
Maarit J. Korpi-Lagg, Mordecai-Mark Mac Low, Frederick A. Gent
Galaxies are observed to host magnetic fields with a typical total strength of around 15microgauss. A coherent large-scale field constitutes up to a few microgauss of the total, wh…
Transition from small-scale to large-scale dynamo in a supernova-driven, multiphase medium
Frederick A. Gent, Mordecai-Mark Mac Low, Maarit J. Korpi-Lagg
Magnetic fields are widely recognised as critical at many scales to galactic dynamics and structure, including multiphase pressure balance, dust processing, and star formation. Usi…
The small-scale dynamo in a multiphase supernova-driven medium
Frederick A. Gent, Mordecai-Mark Mac Low, Maarit J. Korpi-Lagg +1
Magnetic fields grow quickly, even at early cosmological times, suggesting the action of a small-scale dynamo (SSD) in the interstellar medium (ISM) of galaxies. Many studies have…
