A bright X-ray transient was detected by Chandra on 2002 June 2 with a series of 5 HRC-I snapshots. The new source CXOU J004154.6+405648 (R.A.=00h41m54s.64, Dec...
Chandra observations on Jan 16, 2002 surveyed M31 with a series of 5 short (1ks) HRC images. Preliminary analysis yields the following info on new transients...
On Nov 19, 2001, The Chandra X-ray Observatory surveyed M31 with 5 overlapping very short (1ks) HRC exposures and a single short (5ks) ACIS-S exposure...
We propose to observe the peculiar neutron star low mass X-ray binary (NS/LMXB) 2S 1803-245 in quiescence. Together with EXO 1745-248, it is the only transient...
Following our optical monitoring of the halo black-hole candidate XTE J1118+480 (ATELs #383, #402, #424), we have obtained time-resolved R-band photometry with...
XTE J1752-223 has faded to quiescence: optical and infrared magnitudes
We have been regularly monitoring the outburst decay of the black hole candidate X-ray binary XTE J1752-223 (discovered by RXTE; ATel #2258) with the 2-m...
We observed the black hole candidate XTE J1752-223 (ATel #2258) with the William Herschel Telescope (WHT) and the ACAM imager/spectrograph at the Observatorio...
