A Census of Compact Elliptical Galaxies in the Coma Cluster
Aleksandra V. Sharonova, Kirill A. Grishin, Igor V. Chilingarian +3
Compact elliptical (cE) galaxies are compact stellar systems with stellar masses of and radii typically < 0.6 kpc. Here we investigate the prop…
Our Halo of Ice and Fire: Strong Kinematic Asymmetries in the Galactic Halo
Jiwon Jesse Han, Charlie Conroy, Dennis Zaritsky +4
The kinematics of the stellar halo hold important clues to the assembly history and mass distribution of the Galaxy. In this study, we map the kinematics of stars across the Galact…
Measuring M31 globular cluster ages and metallicities using both photometry and spectroscopy
Christopher Usher, Nelson Caldwell, Ivan Cabrera-Ziri
The ages and metallicities of globular clusters play an important role not just in testing models for their formation and evolution but in understanding the assembly history for th…
The colour magnitude relation for galaxies in the Coma cluster
A. I. Terlevich, N. Caldwell, R. G. Bower
We present a new photometric catalogue of the Coma galaxy cluster in the Johnson U- and V- bands. We cover an area of 3360arcmin2 of sky, to a depth of V=20 mag in a 13 arcsec diam…
A Black Hole of > 6 Solar Masses in the X-ray Nova XTE J1118+480
J. E. McClintock, M. R. Garcia, N. Caldwell +3
Observations of the quiescent X-ray nova XTE J1118+480 with the new 6.5-m MMT have revealed that the velocity amplitude of the dwarf secondary is 698 +/- 14 km/s and the orbital pe…
