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…
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…
Optical and X-ray observations of the neutron star soft X-ray transient XTE J1709-267
P. G. Jonker, D. K. Galloway, J. E. McClintock +3
We report on the discovery of the optical counterpart to the neutron star soft X-ray transient (SXT) XTE J1709-267 in outburst and quiescence. We further report the detection of ty…
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…
