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 conduct the largest systematic search for active galactic nuclei (AGN) signa…

DESI EDR: Calibrating the Tully-Fisher Relationship with the DESI Peculiar Velocity Survey

K. Douglass, S. BenZvi, N. Uberoi +45

We calibrate the Tully-Fisher relation (TFR) with data from the DESI Peculiar Velocity (PV) Survey taken during the Survey Validation (SV) period of the DESI galaxy redshift survey…

Beyond Traditional Diagnostics: Identifying Active Galactic Nuclei with Spectral Energy Distribution Fitting in DESI Data

M. Siudek, M. Mezcua, C. Circosta +36

Active galactic nuclei (AGN) are typically identified through their distinctive X-ray or radio emissions, mid-infrared (MIR) colors, or emission lines. However, each method capture…

DESI Emission-line Galaxies: Clustering Dependence on Stellar Mass and [OII] Luminosity

T. Hagen, K. S. Dawson, Z. Zheng +49

We measure the projected two-point correlation functions of emission-line galaxies (ELGs) from the Dark Energy Spectroscopic Instrument (DESI) One-Percent Survey and model their de…

Tripling the Census of Dwarf AGN Candidates Using DESI Early Data

Ragadeepika Pucha, S. Juneau, Arjun Dey +46

Using early data from the Dark Energy Spectroscopic Instrument (DESI) survey, we search for AGN signatures in 410,757 line-emitting galaxies. By employing the BPT emission-line rat…

DESI Emission Line Galaxies: Unveiling the Diversity of [OII] Profiles and its Links to Star Formation and Morphology

Ting-Wen Lan, J. Xavier Prochaska, John Moustakas +34

We study the [OII] profiles of emission line galaxies (ELGs) from the Early Data Release of the Dark Energy Spectroscopic Instrument (DESI). To this end, we decompose and classify…

A Large Sample of Extremely Metal-poor Galaxies at Identified from the DESI Early Data

Hu Zou, Jipeng Sui, Amélie Saintonge +32

Extremely metal-poor galaxies (XMPGs) at relatively low redshift are excellent laboratories for studying galaxy formation and evolution in the early universe. Much effort has been…
