The RXTE has been monitoring the new transient X-ray source MAXI J1409-619 since its discovery on October 20, 2010 (Yamaoka et al 2010, ATEL # 2959) . We...
Discovery of 1 Hz quasi-periodic oscillations in an RXTE observation of MAXI J1543-564
We report on an RXTE follow-up observation of the ongoing outburst of the newly discovered transient X-ray source MAXI J1543-564 (ATELs #3330 and #3331). At ~2...
Discovery of 10 mHz quasi-periodic oscillations likely from IGR J17091-3624
We report the discovery of ~10 mHz quasi-periodic oscillations (QPOs) in a 3.5 ks RXTE observation of the black hole candidate IGR J17091-3624 (ATELs #3144,...
Discovery of 11 Hz burst oscillations from the 11 Hz Eclipsing Pulsar in Terzan 5
An RXTE pointed observation of the ongoing outburst of of the transient source in the globular cluster Terzan 5 (ATEL #2919, #2920, #2922, #2924, #2929) began...
Discovery of a Giant Planet Candidate Transiting a White Dwarf
We report the discovery of a giant planet candidate transiting a white dwarf star. The planet candidate orbits its host star every 1.4 days, is about the size...
Discovery of a lensed ultrabright submillimeter galaxy at z=2.0439
We report an ultra-bright lensed submillimeter galaxy (SMG) at z=2.0439, WISE J132934.18+224327.3, identified as a result of a full-sky cross-correlation of the...
Discovery of a wide planetary-mass companion of a brown dwarf in the Upper Scorpius association
We present the discovery of a 14-8+2 MJup companion located at 670 AU from UScoC-TIO 108, a 60+/-20 MJup brown dwarf of the very young Upper Scorpius...
