A Possible Detection of M31* with Chandra
M. R. Garcia, B. F. Williams, F. Yuan +5
Two independent sets of Chandra and HST images of the nuclear region of M31 allow registration of X-ray and optical images to 0.1''. This registration shows that none of the bright…
Discovery of an X-ray Nova in M31
Benjamin F. Williams, Michael R. Garcia, Albert K. H. Kong +2
We have obtained snapshot images of an X-ray nova in M31 from Chandra ACIS-I and the Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS). The Chandra position of the X-r…
X-ray/Optical/Radio Observations of a Resolved Supernova Remnant in NGC 6822
A. K. H. Kong, L. O. Sjouwerman, B. F. Williams
The supernova remnant (SNR), Ho 12, in the center of the dwarf irregular galaxy NGC 6822 was previously observed at X-ray, optical, and radio wavelengths. By using archival Chandra…
Two New X-ray/Optical/Radio Supernova Remnants in M31
B. F. Williams, L. O. Sjouwerman, A. K. H. Kong +3
We compare a deep (37 ks) Chandra ACIS-S image of the M31 bulge to Local Group Survey narrow-band optical data and Very Large Array (VLA) radio data of the same region. Our precise…
Why are X-ray sources in the M31 Bulge so close to Planetary Nebulae?
Benjamin F. Williams, Michael R. Garcia, Jeffrey E. McClintock +1
We compare a deep (37 ks) Chandra ACIS-S image of the M31 bulge to deep [O III] Local Group Survey data of the same region. Through precision image alignment using globular cluster…
