CURRENT RESEARCH
My research interests are primarily in low-frequency gravitational wave
astrophysics and data analysis, but I'm also interested in various aspects
of cosmology, binary star evolution, and gravitational dynamics in
exoplanetary systems.
Here are a few things that I am currently working on:
- Considering what information about the structure of the galaxy is
embedded in the confusion background of low frequency G-waves (with
Taylor and Benacquista).
- Considering the self-gravity influence on gravitational wave emission
from isolated magnetars (with Purdue).
- Characterizing the Integrated Sachs Wolfe effect on gravitational
wave signals and the resulting impact in science analysis (with
Laguna and Yunes).
- Development of gravitational wave analysis techniques for detecting
eccentric binary systems (with Hellings).
- Simulation of Roche Lobe overflow in compact (gravitational wave
emitting) binary systems (with Knight).
- Full simulation of the "zero signal solution" using LISA simulators,
like Vallisneri and Armstrong's "Synthetic LISA" (with Tinto,
Vallisneri and Drasco).
- Extending, enhancing and applying the gCLEAN algorithm (for
subtracting binary gravitational wave sources from LISA data streams) to
mock LISA data.
RECENTLY COMPLETED
- Reexamination of the overlap reduction function that characterizes
using multiple gravitational wave observatories to detect cosmological
backgrounds (paper submitted to Physical Review D, with
Romano and Finn.
- Estimated the contribution to the gravitational wave confusion
foreground from mass transferring binaries in the galaxy (paper submitted to
Astrophysical Journal, with
Benacquista, Belczynski and Ruiter).
- Paper describing development of university based high altitude
balloon systems for student access to near space (paper
submitted to American Journal of Physics, with
Hiscock and Armstrong).
