RESEARCH HIGHLIGHTS

H-alpha image of the well-known objects M81 and M82, a pair of interacting galaxies at redshift z=0.0 (less than 10 million light years away -- almost our back yard), taken with the KPNO Burrell-Schmidt telescope.

I-band image of a pair of interacting galaxies at redshift z=0.408 (about 4 billion light years away), taken at the 10-meter Keck telescope. Click here to see a spectrum.

Spectrum of the Coup Fourre galaxy, a Lyman-alpha galaxy at z=2.3 (about 12 billion light years away), from the Multiple Mirror Telescope.
