ANNZ+: an enhanced photometric redshift estimation algorithm with applications on the PAU Survey
Imdad Mahmud Pathi, John Y. H. Soo, Mao Jie Wee +16
ANNZ is a fast and simple algorithm which utilises artificial neural networks (ANNs), it was known as one of the pioneers of machine learning approaches to photometric redshift est…
DESI Massive Post-Starburst Galaxies at have compact structures and dense cores
Yunchong Zhang, David J. Setton, Sedona H. Price +33
Post-starburst galaxies (PSBs) are young quiescent galaxies that have recently experienced a rapid decrease in star formation, allowing us to probe the fast-quenching period of gal…
The first identification of Lyman Changing-look Quasars at high-redshift in DESI
Wei-Jian Guo, Zhiwei Pan, MaÅgorzata Siudek +38
We present two cases of Ly changing-look (CL) quasars (J1306 and J1512) along with two additional candidates (J1511 and J1602), all discovered serendipitously at through…
DESIVAST: A Catalog of Low-Redshift Voids using Data from the DESI DR1 Bright Galaxy Survey
Hernan Rincon, Segev BenZvi, Kelly Douglass +40
We present three separate void catalogs created using a volume-limited sample of the DESI Year 1 Bright Galaxy Survey. We use the algorithms VoidFinder and V2 to construct void cat…
The rate of extreme coronal line emitting galaxies in the Sloan Digital Sky Survey and their relation to tidal disruption events
Joseph Callow, Or Graur, Peter Clark +27
High-ionization iron coronal lines (CLs) are a rare phenomenon observed in galaxy and quasi-stellar object spectra that are thought to be created by high-energy emission from activ…
The Atacama Cosmology Telescope DR6 and DESI: Structure growth measurements from the cross-correlation of DESI Legacy Imaging galaxies and CMB lensing from ACT DR6 and Planck PR4
Frank J. Qu, Qianjun Hang, Gerrit Farren +51
We measure the growth of cosmic density fluctuations on large scales and across the redshift range through the cross-correlation of the ACT DR6 CMB lensing map and gala…
