My current research interests are in the areas of Gamma Ray Bursts and Star
Formation. With the launch of NASA's SWIFT satellite,
there is added urgency to make detailed calculations of the broad band
emission in radio, optical and X-rays immediately following the burst of
gamma rays, on time scales that SWIFT is sensitive to, namely,
minutes to hours. Early emission should help us pin down the mass
distribution surrounding gamma ray bursters, which has implications for
the nature of their progenitors.
In the area of star formation, I am working on three projects. The first is to determine how stellar clusters are formed in the presence of feedback from protostellar outflows, which may dominate the dynamics of cluster formation. In the second project, I explore the global properties of magneto-centrifugal outflows from protostellar disks, aiming at connecting the observable flow quantities on large scales to the launching conditions at the disk surface. The goal is to understand the origin of protostellar jets and winds. Lastly, I am investigating how protostellar disks are formed in the collapse of magnetized molecular cores, focusing on the effects of magnetic braking. |
