Formation & evolution of cosmic superstrings: a short review
cosmic superstrings cosmic strings brane inflation M-theory
2010/3/19
I will briefly review the formation and evolution of cosmic superstrings, in the context of brane-world cosmological models within M-theory. These objects can play the role of cosmic strings, offering...
The Cosmological Evolution of Blazars and the Extragalactic Gamma-Ray Background in the Fermi Era
Cosmological Evolution Blazars Extragalactic Gamma-Ray Background
2010/3/8
The latest determination of the extragalactic gamma-ray background (EGRB) radiation by Fermi is compared with the theoretical prediction of the blazar component by Inoue & Totani (2009; hereafter IT09...
Evolution of Infrared Luminosity functions of Galaxies in the AKARI NEP-Deep field: Revealing the cosmic star formation history hidden by dust

Molecular clouds have a hierarchical structure from few tens of
parsecs for giants to few tenth of a parsec for proto-stellar cores. Nowadays, our
observational techniques are so advanced that it ha...
