Ultraluminous X-ray bursts in two ultracompact companions to nearby elliptical galaxies
Jimmy A. Irwin, W. Peter Maksym, Gregory R. Sivakoff +8
An X-ray flaring source was found near the galaxy NGC 4697. Two flares were seen, separated by four years. The flux increased by a factor of 90 on a timescale of about one minute.…
Discovery of the Candidate Off-nuclear Ultrasoft Hyper-luminous X-ray Source 3XMM J141711.1+522541
Dacheng Lin, Eleazar R. Carrasco, Natalie A. Webb +8
We report the discovery of an off-nuclear ultrasoft hyper-luminous X-ray source candidate 3XMM J141711.1+522541 in the inactive S0 galaxy SDSS J141711.07+522540.8 (z=0.41827, d_L=2…
Suzaku X-ray Observations of the Nearest Non-Cool Core Cluster, Antlia: Dynamically Young but with Remarkably Relaxed Outskirts
Ka-Wah Wong, Jimmy A. Irwin, Daniel R. Wik +4
We present the results of seven Suzaku mosaic observations (>200 ks in total) of the nearest non-cool core cluster, the Antlia Cluster (or Group), beyond its degree-scale virial ra…
