Abstract The China Space Station Telescope (CSST) is a forthcoming space-based optical telescope designed to co-orbit with the Chinese Station. With planned slitless spectroscopic survey spanning broad wavelength range of 255 − 1000 nm and an average spectral resolution exceeding 200, CSST holds significant potential for cosmic large-scale structure analysis. In this study, we focus on redshift determinations from spectra through emission line analysis within framework. Our tailored...
Abstract In this study, we present the construction of a new proper-motion catalog utilizing photometric data from Sloan Digital Sky Survey (SDSS) and Dark Energy Spectroscopic Instrument (DESI) imaging surveys, with median time baseline about 13 yr. To mitigate systematic errors, DESI galaxy positions are employed to establish reference frame correct position-, magnitude-, color-dependent discrepancies between SDSS sets. Spanning 12,589 deg 2 , encompasses 223.7 million non-Gaia objects...
Abstract We present the identification of changing-look active galactic nuclei (CL-AGNs) from Dark Energy Spectroscopic Instrument First Data Release and Sloan Digital Sky Survey 16 at z ≤ 0.9. To confirm CL-AGNs, we utilize spectral flux calibration assessment via an [O iii ]-based calibration, pseudophotometry examination, visual inspection. This rigorous selection process allows us to compile a statistical catalog 561 encompassing 527 H β , 149 α 129 Mg ii CL behaviors. In this sample,...
