On the origin of the metallicity dependence in dynamically formed extragalactic low-mass X-ray binaries
N. Ivanova, T. Fragos, D. -W. Kim +6
Globular clusters (GCs) effectively produce dynamically-formed low-mass X-ray binaries (LMXBs). Observers detect ~100 times more LMXBs per stellar mass in GCs compared to stars in…
Metallicity Effect on LMXB Formation in Globular Clusters
D. -W. Kim, G. Fabbiano, N. Ivanova +4
We present comprehensive observational results of the metallicity effect on the fraction of globular clusters (GC) that contain low-mass X-ray binaries (LMXB), by utilizing all ava…
A superburst candidate in EXO 1745--248 as a challenge to thermonuclear ignition models
D. Altamirano, L. Keek, A. Cumming +6
We report on Chandra, RXTE, Swift/BAT and MAXI observations of a ~1 day X-ray flare and subsequent outburst of a transient X-ray source observed in October-November 2011 in the glo…
No Evidence for Intermediate-Mass Black Holes in Globular Clusters: Strong Constraints from the JVLA
Jay Strader, Laura Chomiuk, Thomas Maccarone +4
With a goal of searching for accreting intermediate-mass black holes (IMBHs), we report the results of ultra-deep Jansky VLA radio continuum observations of the cores of three Gala…
A Transient Sub-Eddington Black Hole X-ray Binary Candidate in the Dust Lanes of Centaurus A
Mark J. Burke, Somak Raychaudhury, Ralph P. Kraft +18
We report the discovery of a bright X-ray transient, CXOU J132527.6-430023, in the nearby early-type galaxy NGC 5128. The source was first detected over the course of five Chandra…
The Future of X-ray Time Domain Surveys
Daryl Haggard, Gregory R. Sivakoff
Modern X-ray observatories yield unique insight into the astrophysical time domain. Each X-ray photon can be assigned an arrival time, an energy and a sky position, yielding sensit…
