Extra-planar Diffuse Hot Gas Around Normal Disk Galaxies
Q. Daniel Wang
I review results from {\sl Chandra} observations of nearby normal edge-on galaxies (Sd to Sa types). These galaxies have a broad range of star formation rate, but none of them is d…
Exploring the Nature of Weak Chandra Sources near the Galactic Centre
R. M. Bandyopadhyay, K. M. Blundell, Ph. Podsiadlowski +5
We present early results from the first IR imaging of the weak X-ray sources discovered in a recent Chandra survey towards the Galactic Centre. From our VLT observations we will id…
A new population of X-ray transients in the Galactic Centre
Masaaki Sakano, Robert S. Warwick, Anne Decourchelle +1
A comparison of the XMM-Newton and Chandra Galactic Centre (GC) Surveys has revealed two faint X-ray transients with contrasting properties. The X-ray spectrum of XMM J174544-2913.…
Chandra Observations of the Galactic Center and Nearby Edge-on Galaxies
Q. Daniel Wang
I review our recent Chandra surveys of the center region of the Milky Way and other nearby edge-on galaxies. Our Galactic center survey provides an unprecedented high-resolution, b…
On the Nature of the X-ray Emission from the Galactic Center Region
Q. D. Wang, E. V. Gotthelf, C. C. Lang
The origin of the X-ray emission from the central region of the Galaxy has remained a mystery, despite extensive study over the past two decades. A fundamental question is the rela…
Hiccups in the night: X-ray monitoring of the two Crab-like LMC pulsars
E. V. Gotthelf, W. Zhang, F. E. Marshall +2
We are undertaking an extensive X-ray monitoring campaign of the two Crab-like pulsars in the Large Magellanic Clouds, PSR B0540-69 and PSR J0537-6910. We present our current phase…
