A Partial Lyman Limit Absorber in the Halo of a Galaxy Pair: A Possible Signature of Gas Inflow
Sumukha R. Bharadwaj, Anand Narayanan, Sowgat Muzahid +2
We present an analysis of a partial Lyman limit system at z = 0.87641 detected in the HST/COS spectrum of the background quasar LBQS 0107-0235. The absorber exhibits a simple kinem…
Cosmic ray heating of cold streams: Implications for the gas supply and growth of massive galaxies
Ellis R. Owen, Nicolas Ledos, Evangelia Ntormousi +3
Recent observations have demonstrated the presence of cosmic rays (CRs) in cosmic-web filaments. Cold streams supply gas inflows from these filaments into massive galaxies during t…
A quiescent galaxy in a gas-rich cosmic web node at z~3
Weichen Wang, Sebastiano Cantalupo, Marta Galbiati +11
Recent JWST observations have unveiled a large number of quiescent galaxies at , bringing potential challenges to current galaxy formation models. Since star formation i…
Strong environmental AGN enhancement among DSFGs in z > 2 protoclusters
Monica Natalia Isla Llave, Fabio Vito, Alberto Traina +17
Galaxy protoclusters (PCs) at z > 2 are dense regions in which cold gas availability and elevated galaxy interaction rates trigger intense, often dust-obscured, star formation. The…
The galaxy-halo connection and the dynamical evolution of a giant disc in a massive node of the Cosmic Web at z~3
G. Quadri, S. Cantalupo, C. Bacchini +9
Recent JWST observations revealed the surprising presence of a giant and massive disc galaxy in a Cosmic Web node at z. This galaxy, named the Big Wheel, has a size almost t…
A Comprehensive Study of Morphology and Kinematics in Extended Nebulae Around UV Luminous Quasars at
Zhuoqi Liu, Sean D. Johnson, Eric F. Bell +22
Gas flows between galaxies and the circumgalactic medium (CGM) play a central role in galaxy evolution and can become observable as giant nebulae when illuminated by the quasars. W…
