SSL Colloquium on Nov. 1st: Martin White

Cosmic sound, near and far The coupling of baryons and photons by Thomson scattering in the early universe leads to a rich structure in the power spectra of the cosmic microwave background photons and the matter.  The study of the former has revolutionized cosmology and allowed precise measurement of a host of important cosmological parameters. The study of the latter

SSL Colloquium: Christoph Weniger

Christoph Weniger (Max-Planck-Institut für Physik, Germany) will present the SSL colloquium on May 3rd: `Recently, we identified a tentative gamma-ray line in the Galactic center observations of the Fermi LAT, which would be an unequivocal smoking-gun signature for dark matter annihilation in the Universe. One year after discovery, the signature is still as ambiguous as
