Widespread Inflows Reveal Baryonic Cycling in Star-forming and Quiescent Galaxies
Hassen M. Yesuf, Ravi Joshi, Yuxuan Zou +8
Cool-gas inflows, required to sustain star formation, have been fundamental in simulations yet remained observationally elusive. Using DESI spectroscopy of ~30,000 galaxies, we ide…
Feeding and Feedback in Dwarf Galaxies (FeeD) -- I. Evidence of nuclear ultra-fast and galaxy-scale outflows in the dwarf galaxy Arp 151
Santanu Mondal, Ankit Patel, Mar Mezcua +5
Feeding and feedback regulated by supermassive black holes (SMBHs) play a central role in galaxy growth and evolution, yet these processes remain poorly understood in low-mass gala…
DESI as sparse Integral Field Spectrograph I: Spatially resolved chemical enrichment in star-forming galaxies at
Vibhore Negi, Ravi Joshi, B. Vishnupriya +8
We present a spatially resolved chemical abundance analysis of 2291 star-forming galaxies at , spanning nearly four orders of magnitude in stellar mass ($8 \le \rm log…
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 $…
Baryonic Ecosystem in Galaxies (BEINGMgII). Host Galaxies of Ultra-strong MgII Absorbers in Subaru Hyper Suprime-Cam Survey
Ravi Joshi, Sarbeswar Das, Michele Fumagalli +5
We study the galaxies hosting ultra-strong MgII (USMgII) absorbers at small impact parameters of 2" (5 - 20 kpc), spanning a redshift range of , using deep…
Star-Formation in Neutral Hydrogen Gas Reservoirs at Cosmic Noon
Dharmender, Ravi Joshi, Michele Fumagalli +3
We aim to constrain the average star formation associated with neutral hydrogen gas reservoirs at cosmic noon. Using a unprecedented sample of 1716 high column density Damped Ly-$α…
Baryonic Ecosystem in Galaxies (BEINGMgII) -- II. Unveiling the Nature of Galaxies Harboring Cool Gas Reservoirs
S. Das, R. Joshi, R. Chaudhary +4
We search for the galaxies associated with the intervening MgII absorbers over a redshift range of using imaging data from DESI Legacy Imaging Surveys and measu…
