Investigating ChaMPlane X-ray sources in the Galactic Bulge with Magellan LDSS2 spectra
Xavier Koenig, Jonathan E. Grindlay, Maureen van den Berg +4
We have carried out optical and X-ray spectral analyses on a sample of 136 candidate optical counterparts of X-ray sources found in five Galactic-bulge fields included in our Chand…
The Brightest Serendipitous X-ray Sources in ChaMPlane
Kyle Penner, Maureen van den Berg, JaeSub Hong +3
The Chandra Multiwavelength Plane (ChaMPlane) Survey is a comprehensive effort to constrain the population of accretion-powered and coronal low-luminosity X-ray sources (L_X < 10^3…
X-ray Processing of ChaMPlane Fields: Methods and Initial Results for Selected Anti-Galactic Center Fields
JaeSub Hong, Maureen van den Berg, Eric M. Schlegel +4
We describe the X-ray analysis procedure of the on-going Chandra Multiwavelength Plane (ChaMPlane) survey and report the initial results from the analysis of 15 selected anti-Galac…
Chandra Multiwavelength Plane (ChaMPlane) Survey: an Introduction
J. E. Grindlay, J. Hong, P. Zhao +7
We introduce the Chandra Multiwavelength Plane (ChaMPlane) Survey, designed to measure or constrain the populations of low-luminosity (Lx > ~10^31 erg/s) accreting white dwarfs, ne…
New spectral classification technique for X-ray sources: quantile analysis
Jaesub Hong, Eric M. Schlegel, Jonathan E. Grindlay
We present a new technique called "quantile analysis" to classify spectral properties of X-ray sources with limited statistics. The quantile analysis is superior to the conventiona…
Cathode depth sensing in CZT detectors
J. Hong, E. C. Bellm, J. E. Grindlay +1
Measuring the depth of interaction in thick Cadmium-Zinc-Telluride (CZT) detectors allows improved imaging and spectroscopy for hard X-ray imaging above 100 keV. The Energetic X-ra…
Optimizing wide-field coded aperture imaging: radial mask holes and scanning
J. Grindlay, J. Hong
Imaging at hard X-ray energies (~10-600 keV) over very large fields of view (~60 deg per telescope) is required to conduct a high sensitivity all-sky and all-time survey for black…
Instability of the 13.8 day period in X-ray emission from 4U1700-377
JaeSub Hong, Charles J. Hailey
We present a new result on long-term periodicity searches of the X-ray emission from 4U1700-377 using RXTE ASM and CGRO BATSE data. The hard X-ray data (20 - 200 keV) from early BA…
