Spatially-Resolved Spectra of Diffuse Galactic Light using 10.8 M DESI Sky Fibers

Andrew K. Saydjari, Bruce T. Draine, Timothy D. Brandt +49

Using 10.8 million ``blank'' sky spectra from the DESI Year 3 dataset, we measure the diffuse galactic light (DGL) spectrum in the optical at spectral resolution by c…

The Composite Spectrum of QSO Absorption Line Systems in DESI DR2

Lucas Napolitano, Adam D. Myers, Adam Tedeschi +43

We present details regarding a composite spectrum of quasar (QSO) absorption line systems. In this composite spectrum we identify more than 70 absorption lines, and observe oxygen…

Effect of local environment on Ly line profile in DESI/ODIN LAEs

Ana Sofía M. Uzsoy, Arjun Dey, Anand Raichoor +51

Lyman-Alpha Emitters (LAEs) are star-forming galaxies with significant Ly emission and are often used as tracers of large-scale structure at high redshift. We explore the relati…

A New Way to Discover Strong Gravitational Lenses: Pair-wise Spectroscopic Search from DESI DR1

Yuan-Ming Hsu, Xiaosheng Huang, Christopher J. Storfer +47

We present a new method to search for strong gravitational lensing systems by pairing spectra that are close together on the sky in a spectroscopic survey. We visually inspect 26,6…

The atomic gas sequence and mass-metallicity relation from dwarfs to massive galaxies

D. Scholte, A. Saintonge, J. Moustakas +43

Galaxy scaling relations provide insights into the processes that drive galaxy evolution. The extension of these scaling relations into the dwarf galaxy regime is of particular int…

Probing the impact of radio-mode feedback on the properties of the cool circumgalactic medium

Yu-Ling Chang, Ting-Wen Lan, J. Xavier Prochaska +33

We explore the influence of radio-mode feedback on the properties of the cool circumgalactic medium (CGM). To this end, we assemble a statistical sample of approximately 30,000 rad…
