Measurements of Variability of Low Mass X-ray Binary Candidates in the Early-Type Galaxy NGC 4697 from Multi-Epoch Chandra X-ray Observations
Gregory R. Sivakoff, Andrés Jord'an, Adrienne M. Juett +2
Multi-epoch Chandra X-ray observations of nearby massive early-type galaxies open up the study of an important regime of low-mass X-ray binary (LMXB) behavior -- long term variabil…
Deep Chandra X-ray Observations of Low Mass X-ray Binary Candidates in the Early-Type Galaxy NGC 4697
Gregory R. Sivakoff, Andrés Jordán, Adrienne M. Juett +2
Chandra X-ray observations routinely resolve tens to hundreds of low-mass X-ray binaries (LMXBs) per galaxy in nearby massive early-type galaxies. These studies have raised importa…
On the nature of the z=0 X-ray absorbers: I. Clues from an external group
Smita Mathur, Gregory R. Sivakoff, Rik J. Williams +1
Absorption lines of OVII at redshift zero are observed in high quality Chandra spectra of extragalactic sightlines. The location of the absorber producing these lines, whether from…
A Photometric Survey for Variables and Transits in the Field of Praesepe with KELT
Joshua Pepper, K. Z. Stanek, Richard W. Pogge +5
The Kilodegree Extremely Little Telescope (KELT) project is a small aperture, wide-angle search for planetary transits of solar-type stars. In this paper, we present the results of…
