Broadly speaking, my main interests are in theoretical
astrophysics, high energy physics and cosmology.
I have worked on large scale structure, the intergalactic medium,
gravitational lensing, extra-solar planets, gravitational waves,
inflation, cosmological soft theorems, dark matter, dark energy,
effective field theory for hydrodynamics and black hole perturbation theory.
You can find my publications at the astro-ph,
hep-ph and hep-th archives.
This is a Math afterschool program for Kindergarteners to Third
Graders in Harlem - the
Reading Team Math Program.
for computing velocity two-point correlations, and the associated
magnitude covariance for standard candles (such as supernovae). The
code also contains portions useful for computing power spectrum,
growth factor and cosmic distances.
A series of 3 introductory lectures
