Greg Aldering's Homepage

I've just started this webpage, so it is very incomplete. It mostly contains information that is useful to me, and provides a means for me to exchange information with collaborators within the computer security constraints imposed by DOE.

Summary of Research Interests:

My research is centered on cosmology, including measurement of the cosmological parameters, the exploration of the nature of the "dark energy" and the large-scale distribution of matter in the universe. My current cosmological studies focus on the use Type Ia supernovae as tools for determining the cosmological parameters, through my participation in the Supernova Cosmology Project. I am also a co-investigator on the SuperNova/Acceleration Probe. In order to improve the calibration of supernovae, I have been deeply involved in the recent, highly successful, Spring 1999 Nearby Campaign, and am now the Porject Leader for the forthcoming Nearby Supernova Factory (SNfactory). I am also co-PI on an NSF-sponsored project to analyze a large (100 sq. deg.) survey for low-surface-brightness galaxies. For a glimpse at my paper trail, take a look at my curriculum vitae.
