Home of Dr. DarkMatter

NUTS at MOO (a.k.a. DrDarkMatter) is actually a tenured faculty member in the Physics Department at the University of Oregon who engages mostly in observational astronomy. Dr. DarkMatter is known to work at all hours under a variety of conditions. This is the only known photo of Dr. DarkMatter at work

Dr. DarkMatter's interest are primarily in galaxy evolution and large scale structure, although he is also quite committed to trying to improve the quality of science education not to mention trying to deal with the various aspects of the energy crises on this planet.

Indeed here is a current cv

He also serves as a UNIX system administrator and is involved in trying to use the Network as an Educational Outreach instrument between the University and local area schools as well as the general public. He is the current director of the Pine Mountain Observatory , a facility that offers weekend public programs on the Electronic Universe in which the general public can use a 32-inch telescope with CCD to acquire images and take them home. Our Wide Field CCD Camera (cowcam) is now in place and taking data and we are doing several resarch and outreach projects with it.

Listed below are most of the collected works of Dr. DarkMatter as they represent his "contribution" to Astronomy (and perhaps other areas). These works are arranged by Subject Matter and Year. They are linked to the Journal Title Page Abstract when that is available from the Abstract Service
