On the triple nature of the X-ray source 4U2129+47 (= V1727 Cyg)
M. S. Bothwell, M. P. Torres, M. R. Garcia +1
Context. In quiescence, the proposed optical counterpart to the neutron star low mass X-ray binary 4U 2129+47 (V1727 Cyg) shows a spectrum consistent with a late F-type subgiant an…
A Catalog of Transient X-ray Sources in M31
Benjamin F. Williams, S. Naik, Michael R. Garcia +1
From October 1999 to August 2002, 45 transient X-ray sources were detected in M31 by Chandra and XMM-Newton. We have performed spectral analysis of all XMM-Newton and Chandra ACIS…
UBVRI Light Curves of 44 Type Ia Supernovae
Saurabh Jha, Robert P. Kirshner, Peter Challis +2
We present UBVRI photometry of 44 type-Ia supernovae (SN Ia) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the…
Chandra and Hubble Study of a New Transient X-ray Source in M31
Benjamin F. Williams, Michael R. Garcia, Jeffrey E. McClintock +2
We present X-ray and optical observations of a new transient X-ray source in M31 first detected 23-May-2004 at R.A.=00:43:09.940 +/- 0.65'', Dec.=41:23:32.49 +/- 0.66''. The X-ray…
A Potential Supernova Remnant/X-ray Binary Association in M31
Benjamin F. Williams, Robin Barnard, Michael R. Garcia +3
The well-studied X-ray/Optical/Radio supernova remnant DDB 1-15 (CXOM31 J004327.8+411829; r3-63) in M31 has been investigated with archival XMM-Newton and Chandra observations. The…
On the binary nature of 1RXS J162848.1-415241
M. A. P. Torres, M. R. Garcia, D. Steeghs +1
We present spectroscopy of the optical counterpart to 1RXS J162848.1-41524, also known as the microquasar candidate MCQC J162847-4152. All the data indicate that this X-ray source…
