Discovery of a gas-enshrouded broad-line AGN at z 7
Qianqiao Zhou, Xin Wang, Hang Zhou +9
The Lyman-alpha (Ly) absorption profile in star-forming galaxies serves as a powerful tracer of the extended, dense neutral hydrogen in their surroundings during the Epoch of Re…
Galaxy Metallicity Gradients in the Reionization Epoch from the FIRE-2 Simulations
Xunda Sun, Xin Wang, Fangzhou Jiang +10
We employ the high-redshift suite of FIRE-2 cosmological hydrodynamic zoom-in simulations to investigate the evolution of gas-phase metallicity radial gradients in galaxies in the…
Baryonic Ecosystem IN Galaxies (BEINGMgII) -- III. Cool gas reservoirs at in the Dark Energy Survey
Reena Chaudhary, Ravi Joshi, Sarbeswar Das +5
We investigate the origin of intervening cool MgII absorption detected in the spectra of background quasars and the nature of associated galaxies across a broad redshift range of $…
Overmassive Black holes live in compact galaxies in the early Universe
Yuxuan Wu, Tao Wang, Daizhong Liu +9
A significant population of quasars have been found to exist within the first Gyr of cosmic time. Most of them have high black hole (BH) masses ($M_{\rm BH} \sim 10^{8-10} M_{\odot…
The Dichotomy in the Nuclear and Host Galaxy Properties of High-redshift Quasars
Ruancun Li, Luis C. Ho, Chang-Hao Chen
The early growth of high-redshift quasars and their host galaxies raises critical questions about their cosmic evolution. We exploit the angular resolution and sensitivity of NIRCa…
The Complete Spitzer Survey of Stellar Structure in Galaxies (CSG)
P. M. Sánchez-Alarcón, H. Salo, J. H. Knapen +25
The Spitzer Survey of Stellar Structure in Galaxies (SG), together with its Early Type Galaxy (ETG) extension, stand as the most extensive dataset of deep, uniform mid-infrared…
Clumps as multiscale structures in cosmic noon galaxies
Boris S Kalita, Tomoko L Suzuki, Daichi Kashino +31
Star-forming clumps have been found to significantly influence the star formation of gas-rich galaxies. Using public data from JWST/NIRCam (COSMOS-Web) and ALMA (FMOS-COSMOS)…
Baryonic Ecosystem in Galaxies (BEINGMgII). Host Galaxies of Ultra-strong MgII Absorbers in Subaru Hyper Suprime-Cam Survey
Ravi Joshi, Sarbeswar Das, Michele Fumagalli +5
We study the galaxies hosting ultra-strong MgII (USMgII) absorbers at small impact parameters of 2" (5 - 20 kpc), spanning a redshift range of , using deep…
Star-Formation in Neutral Hydrogen Gas Reservoirs at Cosmic Noon
Dharmender, Ravi Joshi, Michele Fumagalli +3
We aim to constrain the average star formation associated with neutral hydrogen gas reservoirs at cosmic noon. Using a unprecedented sample of 1716 high column density Damped Ly-$α…
