Reconstructing the Accretion History of the Galactic Stellar Halo from Chemical Abundance Ratio Distributions
Duane M. Lee, Kathryn V. Johnston, Bodhisattva Sen +1
Observational studies of halo stars during the last two decades have placed some limits on the quantity and nature of accreted dwarf galaxy contributions to the Milky Way stellar h…
A Mass-Dependent Yield Origin of Neutron-Capture Element Abundance Distributions in Ultra-Faint Dwarfs
Duane M. Lee, Kathryn V. Johnston, Jason Tumlinson +2
One way to constrain the nature of the high-redshift progenitors of the Milky Way is to look at the low-metallicity stellar populations of the different Galactic components today.…
Hot and Cold Galactic Gas in the NGC 2563 Galaxy Group
Jesper Rasmussen, Xue-Ning Bai, John S. Mulchaey +7
The role of environmentally induced gas stripping in driving galaxy evolution in groups remains poorly understood. Here we present extensive Chandra and Very Large Array mosaic obs…
Measuring Transverse Motions for Nearby Galaxy Clusters
Erika T. Hamden, Christine M. Simpson, Kathryn V. Johnston +1
Measuring the full three-dimensional motions of extra-galactic objects in the Universe presents a seemingly insurmountable challenge. In this paper we investigate the application o…
The Coincidence of Nuclear Star Clusters and Active Galactic Nuclei
Anil Seth, Marcel Agueros, Duane Lee +1
We study galaxies that host both nuclear star clusters and active galactic nuclei (AGN) implying the presence of a massive black hole. We select a sample of 176 galaxies with previ…
Deep spectroscopy of 9C J1503+4528: a very young CSS radio source at z=0.521
K. J. Inskip, D. Lee, Garret Cotter +7
9C J1503+4528 is a very young CSS radio galaxy, with an age of order 10^4 years. This source is therefore an ideal laboratory for the study ofthe intrinsic host galaxy/IGM properti…
