Discovery of a Redback Millisecond Pulsar Candidate: 3FGL J0212.1+5320
Kwan-Lok Li, Albert K. H. Kong, Xian Hou +4
We present a multi-wavelength study of the unidentified Fermi object, 3FGL J0212.1+5320. Within the 95% error ellipse, Chandra detects a bright X-ray source (i.e., F(0.5-7keV) = 1.…
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.…
The Gamma-ray Blazar Quest: new optical spectra, state of art and future perspectives
F. Massaro, N. Álvarez Crespo, R. D'Abrusco +13
We recently developed a procedure to recognize gamma-ray blazar candidates within the positional uncertainty regions of the unidentified/unassociated gamma-ray sources (UGSs). Such…
A new gamma-ray loud, eclipsing low-mass X-ray binary
Jay Strader, Kwan-Lok Li, Laura Chomiuk +5
We report the discovery of an eclipsing low-mass X-ray binary at the center of the 3FGL error ellipse of the unassociated Fermi/Large Area Telescope gamma-ray source 3FGL J0427.9-6…
The first low-mass black hole X-ray binary identified in quiescence outside of a globular cluster
B. E. Tetarenko, A. Bahramian, R. M. Arnason +9
The observed relation between the X-ray and radio properties of low-luminosity accreting black holes has enabled the identification of multiple candidate black hole X-ray binaries…
Identifying IGR J14091-6108 as a magnetic CV with a massive white dwarf using X-ray and optical observations
John A. Tomsick, Farid Rahoui, Roman Krivonos +3
IGR J14091-6108 is a Galactic X-ray source known to have an iron emission line, a hard X-ray spectrum, and an optical counterpart. Here, we report on X-ray observations of the sour…
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…
