Target Selection and Validation of DESI Quasars

open access: yesThe Astrophysical Journal, 2023
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 Ly α forests in quasar spectra at z > 2.1.

A Southern Photometric Quasar Catalog from the Dark Energy Survey Data Release 2

open access: yesThe Astrophysical Journal Supplement Series, 2022
We present a catalog of 1.4 million photometrically selected quasar candidates in the southern hemisphere over the ∼5000 deg ^2 Dark Energy Survey (DES) wide survey area. We combine optical photometry from the DES second data release (DR2) with available

Multiscale Stamps for Real-time Classification of Alert Streams

open access: yesThe Astrophysical Journal Letters, 2023
In recent years, automatic classifiers of image cutouts (also called “stamps”) have been shown to be key for fast supernova discovery. The Vera C.

Modeling and Simulation of Sky Survey

open access: yesApplied Sciences, 2021
Sky surveys with wide and deep field are the key direction of international astronomy research for the next decades. It is worthwhile to study how to design a sky survey algorithm to obtain the maximum scientific output in a limited period of observation.

DeepAstroUDA: semi-supervised universal domain adaptation for cross-survey galaxy morphology classification and anomaly detection

open access: yesMachine Learning: Science and Technology, 2023
Artificial intelligence methods show great promise in increasing the quality and speed of work with large astronomical datasets, but the high complexity of these methods leads to the extraction of dataset-specific, non-robust features.

Long-Term Optical Monitoring of Blazars

open access: yesGalaxies, 2019
Systematic monitoring of specific targets in the optical regime was historically applied on a very narrow sample of known variable stars. The discovery of blazars in the 20th century brought to the foreground the need for new global sky surveys, covering
