An empirical model of the Gaia DR3 selection function
Tristan Cantat-Gaudin, Morgan Fouesneau, Hans-Walter Rix +11
Interpreting and modelling astronomical catalogues requires an understanding of the catalogues' completeness or selection function: objects of what properties had a chance to end u…
Mass Segregation in the Hyades Cluster
N. Wyn Evans, Semyeong Oh
Using the Gaia colour-magnitude diagram, we assign masses to a catalogue of 979 confirmed members of the Hyades cluster and tails. By fitting the cumulative mass profile, stars wit…
Spectroscopy of the Young Stellar Association Price-Whelan 1: Origin in the Magellanic Leading Arm and Constraints on the Milky Way Hot Halo
David L. Nidever, Adrian M. Price-Whelan, Yumi Choi +7
We report spectroscopic measurements of stars in the recently discovered young stellar association Price-Whelan 1 (PW 1), which was found in the vicinity of the Leading Arm (LA) of…
Testing the presence of multiple photometric components in nearby early-type galaxies using SDSS
Semyeong Oh, Jenny E. Greene, Claire N. Lackner
We investigate two-dimensional image decomposition of nearby, morphologically selected early-type galaxies (ETGs). We are motivated by recent observational evidence of significant…
The AGN Population in X-ray Selected Galaxy Groups at
Semyeong Oh, John S. Mulchaey, Jong-Hak Woo +6
We use Chandra data to study the incidence and properties of Active Galactic Nuclei (AGN) in 16 intermediate redshift () X-ray-selected galaxy groups in the Chandra…
