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…

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…

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…

ODIN: Spectroscopic Validation of Ly-Emitting Galaxy Samples with DESI

Ethan Pinarski, Govind Ramgopal, Nicole Firestone +65

The One-hundred-deg^2 DECam Imaging in Narrowbands (ODIN) survey is conducting the widest-field deep narrow-band imaging of the equatorial and southern skies. ODIN uses three custo…

Highly Efficient Selection of High-Redshift Emission-Line Galaxies for future DESI-like surveys with Deep Multi-band Imaging

Yoquelbin Salcedo Hernandez, Jeffrey A. Newman, Brett. H. Andrews +53

Emission-line galaxies (ELGs) are an important tracer of baryon acoustic oscillations (BAO) and large-scale structure (LSS) at . In this work, we investigate the feasibility…
