Extracting Photometric Redshift from Galaxy Flux and Image Data using Neural Networks in the CSST Survey
Xingchen Zhou, Yan Gong, Xian-Min Meng +6
The accuracy of galaxy photometric redshift (photo-) can significantly affect the analysis of weak gravitational lensing measurements, especially for future high-precision surve…
Calibrating photometric redshift measurements with the Multi-channel Imager (MCI) of the China Space Station Telescope (CSST)
Ye Cao, Yan Gong, Zhen-Ya Zheng +1
The China Space Station Telescope (CSST) photometric survey aims to perform a high spatial resolution (~0.15'') photometric imaging for the targets that cover a large sky area (~17…
Anisotropies of Cosmic Optical and Near-IR Background from China Space Station Telescope (CSST)
Ye Cao, Yan Gong, Dezi Liu +3
Anisotropies of the cosmic optical background (COB) and cosmic near-IR background (CNIRB) are capable of addressing some of the key questions in cosmology and astrophysics. In this…
Self-calibrating interloper bias in spectroscopic galaxy clustering surveys
Yan Gong, Haitao Miao, Pengjie Zhang +1
Contamination of interloper galaxies due to misidentified emission lines can be a big issue in the spectroscopic galaxy clustering surveys, especially in future high-precision obse…
A global view on star formation: The GLOSTAR Galactic plane survey III. 6.7 GHz methanol maser survey in Cygnus X
Gisela N. Ortiz-León, Karl M. Menten, Andreas Brunthaler +16
The Cygnus X complex is covered by the Global View of Star Formation in the Milky Way (GLOSTAR) survey, an unbiased radio-wavelength Galactic plane survey, in 4--8 GHz continuum ra…
Discovery of 22 GHz Water Masers in the Serpens South Region
Gisela N. Ortiz-León, Adele Plunkett, Laurent Loinard +5
Using the Karl G. Jansky Very Large Array (VLA), we have conducted a survey for 22 GHz, 6_{1,6}-5_{2,3} H2O masers toward the Serpens South region. The masers were also observed wi…
Dense gas in local galaxies revealed by multiple tracers
Fei Li, Junzhi Wang, Feng Gao +6
We present 3 mm and 2 mm band simultaneously spectroscopic observations of HCN 1-0, HCO 1-0, HNC 1-0, and CS 3-2 with the IRAM 30 meter telescope, toward a sample of 70 sourc…
Spectroscopic and Photometric Redshift Estimation by Neural Networks For the China Space Station Optical Survey (CSS-OS)
Xingchen Zhou, Yan Gong, Xian-Min Meng +6
The estimation of spectroscopic and photometric redshifts (spec-z and photo-z) is crucial for future cosmological surveys. It can directly affect several powerful measurements of t…
