A Spitzer Space Telescope Infrared Survey of Supernova Remnants in the Inner Galaxy (2005)

Reach, William T., Rho, Jeonghee, Tappe, Achim, Pannuti, Thomas G., Brogan, Crystal L., Churchwell, Edward B., ...

Using Infrared Array Camera (IRAC) images at 3.6, 4.5, 5.8, and 8 microns from the GLIMPSE Legacy science program on the Spitzer Space Telescope, we searched for infrared counterparts to the 95 known...

Dark Matter and Cold Fractal Clouds (2000)

Tappe, Achim

There is strong evidence for a large fraction of dark matter in the Universe. Some of the evidence and candidates for dark matter are reviewed. Dark matter in spiral galaxies may be in the form of...
