Weak Evolution of Cosmic Atomic Hydrogen over the Past 4.5 Billion Years

Chuan-Peng Zhang, Hong Guo, Yizhou Gu +49

The cosmic star formation rate density (CSFRD) has declined sharply toward the present day, but the roles of the atomic and molecular gas reservoirs remain uncertain. We measure th…

The largest sample of AGN outflows in dwarf galaxies using DESI DR1

V. Rodríguez Morales, M. Mezcua, Ragadeepika Pucha +40

In the last decade, the presence of active galactic nuclei (AGN) outflows and feedback in dwarf galaxies (<) has gained ground over supern…

Peering down the barrel with DESI DR2: 10 000+ inflows at < 0.6 reveal how galaxies accrete cold gas

S. Weng, A. Saintonge, M. Pieri +39

Direct observational constraints on how galaxies acquire their gas remain remarkably limited, hindering our understanding of the baryon cycle. We present a search for down-the-barr…

Joint Modeling of GD-1 and C-19 as Old Streams

Raymond G. Carlberg, Ting S. Li, Emma Jarvis +41

DESI observational data for the GD-1 and C-19 streams are compared to stream simulations in an evolving multi-halo potential of a Milky Way-like galaxy based on a cosmological Milk…

Mapping the nuclear environments of extreme coronal line emitting galaxies

Daniel Kynoch, Or Graur, Peter Clark +30

Extreme coronal line emitters (ECLEs) are a rare class of galactic nuclei exhibiting unusually strong high-ionisation forbidden emission lines, and several ECLEs have been linked t…

A New Record Census of Dwarf AGN and a Bimodal - Scaling Relation with DESI DR1

Ragadeepika Pucha, S. Juneau, M. Mezcua +48

Using the first spectroscopic data release from the Dark Energy Spectroscopic Instrument (DESI DR1), we search for AGN signatures in 1,678,787 low-redshift ()…
