The ANITA (ANtarctic Impulsive Transient Antenna) experiment is an innovative balloon-borne radio telescope, designed to detect coherent Cherenkov emission from cosmogenic ultra high-energy neutrinos with energy greater than 10^18 eV. The second flight of the ANITA experiment launched on December 21st, 2008, and collected data for 30 days. This new data set allows for the most sensitive...

Our understanding of the Universe today includes overwhelming observational evidence for the existence of an elusive form of matter that is generally referred to as dark. Although many theories have been developed to describe its nature, very little is actually known about its properties. The launch of the Fermi Gamma-ray Space Telescope in 2008 opened a new window for the indirect...

In some classes of WIMP models, the Higgs boson could be copiously produced in association
with a photon from dark matter annihilations in the center of our galaxy. The resulting photon spectrum
possesses a line whose energy reflects the mass of the Higgs and of the WIMP and whose intensity
depends on the WIMP spin and statistics. I will discuss how gamma-ray telescopes such as Fermi
could...

The propagation of high energy photons across the Universe is hindered by various radiation fields with which they interact. In this talk we will explain how the presence of an axion like particle can change this propagation and make the Universe more transparent. This results in high energy photons making it across cosmic gulfs we would normally not expect them to be able to traverse. We...
