Stellar populations of galaxies in the LAMOST spectral survey
Li-Li Wang, Shi-Yin Shen, A-Li Luo +7
We firstly derive the stellar population properties: age and metallicity for 43,000 low redshift galaxies in the seventh data release (DR7) of the Large Sky Area Multi-Objec…
Do current X-ray observations capture most of the black-hole accretion at high redshifts?
Guang Yang, Vicente Estrada-Carpenter, Casey Papovich +4
The cosmic black hole accretion density (BHAD) is critical for our understanding of the formation and evolution of supermassive black holes (BHs). However, at high redshifts (…
The XMM-SERVS survey: XMM-Newton point-source catalogs for the W-CDF-S and ELAIS-S1 fields
Q. Ni, W. N. Brandt, C. -T. Chen +30
We present the X-ray point-source catalogs in two of the XMM-Spitzer Extragalactic Representative Volume Survey (XMM-SERVS) fields, W-CDF-S (4.6 deg) and ELAIS-S1 (3.2 deg)…
Photometric Redshifts in the W-CDF-S and ELAIS-S1 Fields Based on Forced Photometry from 0.36 -- 4.5 Microns
Fan Zou, Guang Yang, W. N. Brandt +10
The W-CDF-S and ELAIS-S1 fields will be two of the LSST Deep Drilling fields, but the availability of spectroscopic redshifts within these two fields is still limited on deg^2 scal…
Measuring Stellar Masses of Emission Line Galaxies at 1.2<z<1.9
Gautam Nagaraj, Robin Ciardullo, Alex Lawson +4
The accurate measurement of stellar masses over a wide range of galaxy properties is essential for better constraining models of galaxy evolution. Emission line galaxies (ELGs) ten…
A Multi-Band Forced-Photometry Catalog in the ELAIS-S1 Field
Fan Zou, W. N. Brandt, Mark Lacy +11
The ELAIS-S1 field will be an LSST Deep Drilling field, and it also has extensive multiwavelength coverage. To improve the utility of the existing data, we use The Tractor to perfo…
