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…
Spectroscopy of Supernova Remnants and Candidates in M31
Nelson Caldwell, John C. Raymond, Knox S. Long +1
With a star formation rate of order 0.4 M yr, M31 should have significant population of supernova remnants (SNRs), and, in fact, 156 SNR and SNR candidates have bee…
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 Distance to the S147 Supernova Remnant
C. S. Kochanek, J. C. Raymond, N. Caldwell
In the absence of a parallax distance to a pulsar or a surviving binary in a supernova remnant (SNR), distances to Galactic SNRs are generally very uncertain. However, by combining…
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…
