Systematic uncertainties on DESI Tully-Fisher distances constrained with Integral Field Spectroscopy

Utsav Siwakoti, Lluis Galbany, Kelly A. Douglass +40

The Tully--Fisher (TF) relation is an empirical tool for estimating distances to spiral galaxies. The Dark Energy Spectroscopic Instrument (DESI) Peculiar Velocity (PV) Survey uses…

Luminosity function of quasars at from SDSS and DESI

Gaocheng Yin, Linhua Jiang, Zhiwei Pan +54

We present a study of the evolution of type 1 quasars at , covering the peak epoch of quasar activity. The quasar evolution has been extensively explored by a variety of…

Quiescent Host Galaxies of Extended Quasars Revealed by Spectrophotometric Decomposition

Shengxiu Sun, Linhua Jiang, Zhiwei Pan +27

Previous works of low-redshift quasar host galaxies have focused on compact quasars and found that their host galaxies are mainly star-forming galaxies. Here we present a study of…

Stacked Reverberation Mapping of High Redshift Quasars in DESI. I. Feasibility Analysis

Rahma Alfarsy, R. E. A. Canning, Eva-Maria Mueller +49

The broad line region of quasars has long been probed by reverberation mapping techniques that measure time lags between continuum and broad emission line variations. Stacked rever…

Beyond traditional emission-line diagnostics: using autoencoders to uncover active galactic nuclei in DESI spectra

J. A. Alcolea, M. Siudek, M. Eriksen +49

The growing volume of spectroscopic data in modern surveys motivates data-driven approaches that complement traditional emission-line diagnostics for active galactic nuclei (AGN) i…

Disentangling the Distant Stellar Halo Using K-Giants in the DESI Year 3 Data

Namitha Kizhuprakkat, Andrew P. Cooper, Wenting Wang +42

We present a sample of 88,959 K-giants from DESI Milky Way Survey Year 3 data, which we use to characterize the chemo-dynamical properties of the stellar halo at Galactocentric dis…
