Fermi-LAT Observations of the Diffuse Gamma-Ray Emission: Implications for Cosmic Rays and the Interstellar Medium
Fermi-LAT Observations Diffuse Gamma-Ray Emission Implications Cosmic Rays the Interstellar Medium
2012/2/23
The gamma-ray sky >100 MeV is dominated by the diffuse emissions from interactions of cosmic rays with the interstellar gas and radiation fields of the Milky Way. Observations of these diffuse emissio...
The Galactic dust-to-metals ratio and metallicity using gamma-ray bursts
Gamma-ray burst: general – ISM: abundances – dust, extinction – Galaxy: abundances – X-rays: ISM
2011/10/18
The metallicity and dust-to-metals ratio of the Galaxy are fundamental parameters in understanding the ISM, but there is still uncertainty surrounding these parameters. In this paper, the dust-to-meta...
T Tauri stars are young, low mass, pre-main sequence stars surrounded by an accretion disk. These objects present strong magnetic activity and powerful magnetic reconnection events. Strong shocks are ...
Probing bulk viscous matter-dominated models with Gamma-ray bursts
Probing viscous matter-dominated Gamma-ray bursts
2011/9/27
In this paper we extend the range of consistency of a constant bulk viscosity model to redshifts up to $z\sim 8.1$. In this model the dark sector of the cosmic substratum is a viscous fluid with press...
