Research Interests:
Structure and observable properties of accretion columns in
X-ray pulsars.
Production of radio emission in solar noise storms.
Time-dependent models for particle acceleration in astrophysical
plasmas.
Thermal and bulk Comptonization in accretion flows onto compact objects.
Radiation-dominated shock waves in astrophysical sources.
Particle acceleration and the production of outflows from accretion
disks around black holes.
Stability and structure of cosmic-ray modified shock waves
produced by supernova explosions.
Production of radio emission in cooling-flow clusters
of galaxies.
Attenuation of gamma-rays via photon-photon collisions
in compact sources.
Effects of general relativity on the propagation of
particles near rotating black holes.
Properties of solutions to Heun's and Whittaker's differential
equations, including normalization integrals.
Large-scale automated symbolic computational methods
for solving integro-partial differential equations.
I am currently working with CSI doctoral students
Juan Luna
and Ken Wolfram.
I also continue to collaborate with my former students,
Dr. Truong Le,
who holds an NRC Postdoctoral Fellowship at the Naval Research Laboratory
in Washington, DC, and Dr. Prasad Subramanian, who is now an Assistant Professor at the
Indian Institute of Astrophysics in Bangalore, India.
