X-RAY ASTROPHYSICS
List of Publications
Press Releases
My research interest is X-ray astronomy,
the study of X-ray emitting objects in the universe,
utilizing observations with current X-ray space telescopes
on board Chandra X-Ray Observatory, XMM-Newton Observatory,
and Suzaku X-Ray Observatory. I will also use future
missions such as Astro-H and International X-Ray Observatory.
I have been working on Galactic X-ray sources, primarily
hot interstellar medium (ISM).
Before arriving at UT Arlington in 2010,
at Penn State, I worked for the
Chandra
/ACIS
group led by
Dr.
Gordon P. Garmire, where I primarily worked for the
supernova remnant
group with
Dr. David N. Burrows.
I also worked on various extended X-ray emission in the
Galactic center
as a member of the Chandra Galactic center
group led by Dr. Frederick Baganoff at MIT.
At Laboratory for High Energy
Astrophysics (LHEA) of
NASA/GSFC,
with
Dr. Lorella Angelini and Dr. Nicholas E. White,
I have worked on completing WGACAT
and search/analysis of the WGA variable sources
.
My thesis at Purdue,
under the direction of
Dr.
John P. Finley, in collaboration with
Dr. Steven L. Snowden at
NASA/Goddard Space Flight Center
(GSFC),
was on the study of the soft X-ray background in the
Galactic plane
utilizing ROSAT PSPC observations.
The Galactic soft X-ray background
is still very interesting subject and I continue to explore its nature
utilizing data from
ROSAT,
ASCA,
and XMM-Newton observatories, hoping that,
in the long run, we may understand the global structure and the origins of the
X-ray emitting hot interstellar medium within our own Milky Way
Galaxy.
A brief summary of some of my previous/current works is described
