The Science

Most of the research done by members of the IRA is performed at the Hale 200-inch Telescope at Palomar Observatory near San Diego, California, the two 10-m Keck Telescopes atop Mauna Kea in Hawaii and the Spitzer Space Telescope. From the ground, we work in the "near infrared" range of the electromagnetic spectrum between wavelengths of 1 and 10 microns. With Spitzer, we use all the data from the different instruments.

Some Research projects include:
