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…
DESI DR2 Results IV: Alcock-Paczyński Measurements from the Lyman Alpha Forest and Cosmological Constraints
DESI Collaboration, A. G. Adame, J. Aguilar +164
The DESI DR2 analysis measures the Alcock‑Paczynski effect using the full shape of Lyman‑α forest auto‑ and cross‑correlations, achieving 1% precision at redshift 2.33 and providin…
1000 cataclysmic variables identified from DESI spectroscopy
K. Inight, B. T. Gänsicke, A. Aungwerojwit +41
Most cataclysmic variables (CVs) are discovered when they have an outburst generating an inherent selection bias against CVs that rarely, or never, outburst. CVs discovered by virt…
Probing the matter-dominated expansion with multi-redshift Lyman- BAO from DESI DR2
Hiram K. Herrera-Alcantar, Julien Guy, Alma X. Gonzalez-Morales +60
We present a multi-redshift Baryon Acoustic Oscillations (BAO) analysis of the DESI Data Release 2 (DR2) Lyman- (Ly) forest, splitting the forest auto-correlation and its c…
First planetesimals from DESI DR1: 12 highly metal-rich white dwarfs
Paula Izquierdo, Andrew Swan, Boris T. Gänsicke +43
The paper analyzes 12 highly metal‑rich white dwarfs from DESI DR1, measuring their photospheric metal abundances to infer the bulk composition of the accreted planetary debris, wh…
Clustering of high-redshift quasars with DESI DR2
M. Charles, P. Martini, A. J. Ross +46
We present clustering measurements for high-redshift quasars using data from the Dark Energy Spectroscopic Instrument Data Release 2. Our sample consists of quasars with $2.0 < z <…
