| Title: |
Astrophysical Probe of New Physics: Cosmological Dark Matter and Anisotropy
|
| Abstract: |
I introduce several attempts to probe new physics using astrophysical and cosmological signatures. In this talk, I will focus on particle dark matter and primordial anisotropy of the Universe. The former is one of the biggest unresolved mysteries in cosmology, and the latter is about the hypothesis that one always assumes but should be tested. These approaches include:
- (1) Anisotropy signature of cosmic gamma-ray background from dark matter annihilation;
- (2) Detection of charged massive particles produced by atmospheric and astrophysical neutrinos at neutrino telescopes;
- (3) Effect of nonlinear evolution of primordial anisotropy in the Universe.
All these are related to currently running or upcoming projects such as (1) GLAST, (2) IceCube, and (3) 2dF/SDSS galaxy surveys, respectively.
