On searches for pulsed emission with application to four globular cluster X-ray sources - NGC 1851, 6441, 6624, and 6712
We present the results of searches for periodic pulsations in the X-ray emission from four globular cluster sources, NGC 1851, NGC 6441, NGC 6624, and NGC 6712. The data were obtained by the Monitor…
A Hydrogen Atmosphere Spectral Model Applied to the Neutron Star X7 in the Globular Cluster 47 Tucanae
Current X-ray missions are providing high-quality X-ray spectra from neutron stars (NSs) in quiescent low-mass X-ray binaries (qLMXBs). This has motivated us to calculate new hydrogen atmosphere…
High-Resolution X-ray Imaging of a Globular Cluster Core: Compact Binaries in 47Tuc
These observations provide the first x-ray “color-magnitude” diagram for a globular cluster and census of its compact object and binary population.
HARD X-RAY EMISSION FROM LOW-MASS X-RAY BINARIES
We report on Rossi X-Ray Timing Explorer observations of four type I X-ray bursters, namely, 1E 1724-3045, GS 1826-238, SLX 1735-269, and KS 1731-260. The first three were in a low state, with 1-200…
A relativistic type Ibc supernova without a detected γ-ray burst
The discovery of luminous radio emission from the seemingly ordinary type Ibc SN 2009bb, which requires a substantial relativistic outflow powered by a central engine, is reported.
The Einstein galactic plane survey : statistical analysis of the complete X-ray sample.
Analysis of the Quiescent Low-Mass X-Ray Binary Population in Galactic Globular Clusters
Quiescent low-mass X-ray binaries (qLMXBs) containing neutron stars have been identified in several globular clusters using Chandra or XMM X-ray observations, via their distinctive soft thermal…
A DEEP CHANDRA SURVEY OF THE GLOBULAR CLUSTER 47 TUCANAE: CATALOG OF POINT SOURCES
We have detected 300 X-ray sources within the half-mass radius (279) of the globular cluster 47 Tucanae in a deep (281 ks) Chandra exposure. We perform photometry and simple spectral fitting for our…
The prospects for X-ray detection of inverse-Compton emission from radio source electrons and photons of the microwave background
