cds-question@unistra.frquasarsvisible-astronomyspectroscopysurveysredshiftedline-intensitiesintergalactic-mediumWe present the first result in exploring the gaseous halo and galaxy correlation using the Dark Energy Spectroscopic Instrument survey validation data in the Cosmic Evolution Survey (COSMOS) and Hyper Suprime-Cam field. We obtain multiphase gaseous halo properties in the circumgalactic medium by using 115 quasar spectra (signal-to-noise ratio > 3). We detect MgII absorption at redshift 0.6<z<2.5, CIV absorption at 1.6<z<3.6, and HI absorption associated with the MgII and CIV. By crossmatching the COSMOS2020 catalog, we identify the MgII and CIV host galaxies in 10 quasar fields at 0.9<z<3.1. We find that within the impact parameter of 250kpc, a tight correlation is seen between the strong MgII equivalent width and the host galaxy star formation rate. The covering fraction fc of the strong MgII selected galaxies, which is the ratio of the absorbing galaxy in a certain galaxy population, shows significant evolution in the main-sequence galaxies and marginal evolution in all the galaxy populations within 250kpc at 0.9<z<2.2. The fc increase in the main-sequence galaxies likely suggests the coevolution of strong MgII absorbing gas and the main-sequence galaxies at the cosmic noon. Furthermore, MgII and CIV absorbing gas is detected out of the galaxy virial radius, tentatively indicating the feedback produced by the star formation and/or the environmental effects.2024ApJ...960...34Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/960/34CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/289 : SDSS quasar catalog, sixteenth data release (DR16Q) (Lyke+, 2020)J/MNRAS/371/495 : Catalog of 1806 MgII absorbers from SDSS DR3 (Bouche+, 2006)J/ApJ/639/766 : SDSS-DR3 strong MgII absorbers (Prochter+, 2006)J/ApJ/714/1521 : Spectroscopy of galaxies around distant QSOs (Chen+, 2010)J/ApJ/724/L176 : MgII absorbing gas around galaxies (Chen+, 2010)J/A+A/530/A50 : Principal Component Analysis of QSO UV sp.
