Unveiling Hidden Lyman Alpha Emitters in the DESI DR1 Data
Jui-Kuan Chan, Ting-Wen Lan, J. Xavier Prochaska +39
We present an automatic method based on machine-learning convolutional neural network (CNN) architecture to detect Lyman alpha emitters (LAE) hidden in the Data Release 1 spectrosc…
Tracing the Cosmic Evolution of the Cool Circumgalactic Medium of Luminous Red Galaxies with DESI Year 1 Data
Yu-Ling Chang, Ting-Wen Lan, J. Xavier Prochaska +44
We investigate the properties of the cool circumgalactic medium (CGM) of massive galaxies and their cosmic evolution. By using the year 1 dataset of luminous red galaxies (LRGs) an…

DESI Collaboration, M. Abdul Karim, A. G. Adame +306
In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving three-dimensional s…
A Comprehensive Characterization of Galaxy-cool CGM Connections at with DESI Year 1 Data
Yu Voon Ng, Ting-Wen Lan, J. Xavier Prochaska +41
We investigate the relationships between the cool circumgalactic medium (CGM), traced by Ca II absorption lines, and galaxy properties at using galaxy-quasa…
A Deep Search for a Strong Diffuse Interstellar Band in the Circumgalactic Medium
Chih-Yuan Chang, Ting-Wen Lan
We investigate the absorption signals of a strong diffuse interstellar band, DIB, in the circumgalactic medium (CGM) traced by MgII absorption lines. To this end, we m…
DESI 2024 VII: Cosmological Constraints from the Full-Shape Modeling of Clustering Measurements
