X-ray Constraints on Wandering Black Holes in Stripped Galaxy Nuclei in the Halo of NGC 5128
S. L. Feyan, R. Urquhart, J. Strader +6
A subset of galaxies have dense nuclei, and when these galaxies are accreted and tidally stripped, the nuclei can masquerade as globular clusters in the halos of large galaxies. If…
Cloud-scale elemental abundance variations and the CO-to-dust-mass conversion factor in M31
Chloe Bosomworth, Jan Forbrich, Charles J. Lada +3
From a spectroscopic survey of candidate H II regions in the Andromeda galaxy (M31) with MMT/Hectospec, we have identified 294 H II regions using emission line ratios and calculate…
The Faint Satellite System of NGC 253: Insights into Low-Density Environments and No Satellite Plane
Burçin Mutlu-Pakdil, David J. Sand, Denija Crnojević +12
We have conducted a systematic search around the Milky Way (MW) analog NGC 253 (D=3.5 Mpc), as a part of the Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS) - a Magella…
Hubble Space Telescope Imaging of the Ultra-Compact High Velocity Cloud AGC 226067: A stripped remnant in the Virgo Cluster
D. J. Sand, A. C. Seth, D. Crnojević +10
We analyze the optical counterpart to the ultra-compact high velocity cloud AGC 226067, utilizing imaging taken with the Advanced Camera for Surveys (ACS) on the Hubble Space Teles…
Resolving the extended stellar halos of nearby galaxies: the wide-field PISCeS survey
D. Crnojević, D. J. Sand, N. Caldwell +6
In the wide-field Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS), we investigate the resolved stellar halos of two nearby galaxies (the elliptical Centaurus A and the…
Symbiotic stars in the Local Group of Galaxies
J. Mikolajewska, M. M. Shara, N. Caldwell +3
Preliminary results of the ongoing search for symbiotic binary stars in the Local Group of Galaxies are presented and discussed.
