DESI survey validation data in the COSMOS/HSC field: Cool gas trace main sequence star-forming galaxies at the cosmic noon
Siwei Zou, Linhua Jiang, Zheng Cai +23
We present the first result in exploring the gaseous halo and galaxy correlation using the Dark Energy Spectroscopic Instrument (DESI) survey validation data in the Cosmic Evolutio…
Target Selection and Validation of DESI Quasars
Edmond Chaussidon, Christophe Yèche, Nathalie Palanque-Delabrouille +54
The Dark Energy Spectroscopic Instrument (DESI) survey will measure large-scale structures using quasars as direct tracers of dark matter in the redshift range 0.9<z<2.1 and using…
Deep Learning of DESI Mock Spectra to Find Damped Lyα Systems
Ben Wang, Jiaqi Zou, Zheng Cai +14
We have updated and applied a convolutional neural network (CNN) machine learning model to discover and characterize damped Ly systems (DLAs) based on Dark Energy Spectroscopic…
The PAU Survey: Measurements of the 4000 Å spectral break with narrow-band photometry
Pablo Renard, Małgorzata Siudek, Martin B. Eriksen +19
The D4000 spectral break index is one of the most important features in the visible spectrum, as it is a proxy for stellar ages and is also used in galaxy classification. However,…
Analytic Spectra of CMB Anisotropies and Polarization Generated by Scalar Perturbations in Synchronous Gauge
Zheng Cai, Yang Zhang
We present a detailed analytical calculation of CMB temperature anisotropies α_k and polarization β_k generated by scalar metric perturbations in synchronous gauge, parallel to our…
