Probing Periodic and Aperiodic Variability of X-ray Sources in M31, M81 and Centaurus A with Chandra
Jiachang Zhang, Zhiyuan Li, Ziqian Hua +1
Based on archival Chandra observations, we present a systematic timing survey of several hundred X-ray sources in M31, M81, and Centaurus A, mostly low-mass X-ray binaries (LXMBs),…
The first extragalactic ultra-compact X-ray binary : a candidate black hole-white dwarf system
Qian-Qi Ma, Jiachang Zhang, Wei-Min Gu +3
M31 UCXB-1 is one of the brightest X-ray point sources in the bulge of M31, with a peak X-ray luminosity $ L_{\mathrm{0.5-10 \: keV}} = 2.9^{+0.2}_{-0.2} \times 10^{38} \: \mathrm{…
Ring or no ring -- Revisiting the Multiphase Nuclear Environment in M31
Zongnan Li, Zhao Su, Sumin Wang +9
Nuclear rings, prevalent in barred galaxies, are essential to understanding gas transport toward galactic nuclei. However, the peculiar nuclear ring in our neighboring galaxy M31 r…
A Chandra Search for Periodic X-ray Sources in the Bulge of M31
Jiachang Zhang, Tong Bao, Zhiyuan Li
We present a systematic search for periodic X-ray sources in the bulge of M31, using ~ 2 Ms of archival Chandra observations spanning a temporal baseline of 16 years. Utilizing the…
