Rapid growth in a dual AGN during a gas-rich merger at z~4.5
Hyewon Suh, Roberto Decarli, Emanuele Paolo Farina +15
The late stages of galaxy mergers - when two supermassive black holes (SMBHs) reach kiloparsec-scale separations - represent a critical phase for understanding SMBH growth, galaxy…
Primordial Black Holes Formation Beyond the Standard Cosmic QCD Transition
Maël Gonin, Oleksii Ivanytskyi, David Blaschke +1
We review the role of primordial black holes (PBHs) for illuminating the dark ages of the cosmological evolution and as dark matter (DM) candidates. We elucidate the role of phase…
Primordial black-hole formation and heavy r-process element synthesis from the cosmological QCD transition. Two aspects of an inhomogeneous early Universe
M. Gonin, G. Hasinger, D. Blaschke +2
We review the role of primordial black holes (PBHs) for illuminating the dark ages of the cosmological evolution and as dark matter candidates. We elucidate the role of phase trans…
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…
Tracing High-z Galaxies in X-rays with JWST and Chandra
A. Kaminsky, N. Cappelluti, G. Hasinger +14
We leverage JWST data from the COSMOS-Web Survey in order to provide updated measurements on the auto-power spectrum of the now resolved Cosmic Infrared Background (CIB) and its co…
