Enhancing Multiplet Alignment Measurements with Imaging
Alexus Annika Kumwembe, Claire Lamman, Daniel Eisenstein +35
We demonstrate that measurements of the gravitational tidal field made with spectroscopic redshifts can be improved with information from imaging surveys. The average orientation o…
Combined tracer analysis for DESI 2024 BAO
D. Valcin, M. Rashkovetskyi, H. Seo +64
This paper demonstrates how the Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) and future baryon acoustic oscillations (BAO) analyses can optimally combine overla…
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…
Bayesian Component Separation for DESI LAE Automated Spectroscopic Redshifts and Photometric Targeting
Ana Sofía M. Uzsoy, Andrew K. Saydjari, Arjun Dey +37
Lyman Alpha Emitters (LAEs) are valuable high-redshift cosmological probes traditionally identified using specialized narrow-band photometric surveys. In ground-based spectroscopy,…
Dynamical Dark Energy in light of the DESI DR2 Baryonic Acoustic Oscillations Measurements
Gan Gu, Xiaoma Wang, Yuting Wang +57
Understanding whether cosmic acceleration arises from a cosmological constant or a dynamical component is a central goal of cosmology, and the Dark Energy Spectroscopic Instrument…
DESI Spectroscopy of HETDEX Emission-line Candidates I: Line Discrimination Validation
Martin Landriau, Erin Mentuch Cooper, Dustin Davis +50
The Hobby-Eberly Dark Energy Experiment (HETDEX) is an untargeted spectroscopic galaxy survey that uses Ly emitting galaxies (LAEs) as tracers of 1.9 < z < 3.5 large scale struc…
Iron-corrected Single-epoch Black Hole Masses of DESI Quasars at low redshift
Zhiwei Pan, Linhua Jiang, Wei-Jian Guo +31
We present a study on the possible overestimation of single-epoch supermassive black hole (SMBH) masses in previous works, based on more than 55,000 type 1 quasars at $0.25 < z < 0…
DESI Mg II Absorbers: Extinction Characteristics & Quasar Redshift Accuracy
Lucas Napolitano, Adam D. Myers, Vicky Fawcett +32
In this paper, we study how absorption-line systems affect the spectra and redshifts of quasars (QSOs), using catalogs of Mg II absorbers from the early data release (EDR) and firs…
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…
The DESI One-Percent survey: exploring the Halo Occupation Distribution of Emission Line Galaxies with AbacusSummit simulations
Antoine Rocher, Vanina Ruhlmann-Kleider, Etienne Burtin +50
The One-Percent survey of the Dark Energy Spectroscopic Instrument collected ~ 270k emission line galaxies (ELGs) at 0.8 < z < 1.6. The high completeness of the sample allowed the…
