Constraints on a hadronic model for unidentified off-plane galactic gamma-ray sources
hadronic model unidentified off-plane galactic gamma-ray sources
2011/1/10
Recently the H.E.S.S. collaboration announced the detection of an unidentified gamma-ray source with an off-set from the galactic plane of 3.5 degrees: HESS J1507-622. If the distance of the object is...
Review: A Coherent and Comprehensive Model of the Evolution of the Outer Solar System
Comprehensive Model the Outer Solar System
2011/1/13
Since the discovery of the first extra-solar planets, we are confronted with the puzzling diversity of planetary systems. Processes like planet radial migration in gas-disks and planetary orbital inst...
A Halo Model of Local IRAS Galaxies Selected at 60 Micron Using Conditional Luminosity Functions
Local IRAS Galaxies Selected 60 Micron
2011/1/11
Using conditional luminosity functions (CLFs) which encode the luminosity distribution of galaxies as a function of halo mass, we construct a halo model of IRAS galaxies selected at 60 micron. An abun...

Macroscopic Geo-Magnetic Radiation Model Polarization effects finite volume calculations
2011/1/11
An ultra-high-energy cosmic ray (UHECR) colliding with the Earth's atmosphere gives rise to an Extensive Air Shower (EAS). Due to different charge separation mechanisms within the thin shower front co...
Cluster morphologies and model-independent Y_SZ estimates from Bolocam Sunyaev-Zel'dovich images
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We present initial results from our ongoing program to image the Sunyaev-Zel'dovich (SZ) effect in galaxy clusters at 143 GHz using Bolocam; five clusters and one blank field are described in this man...
3D hydrodynamical CO5BOLD model atmospheres of late-type giants: chemical abundances from molecular lines
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
We investigate the influence of convection on the formation of molecular spectral lines in the atmospheres of late-type giants. For this purpose we use the 3D hydrodynamical CO5BOLD and classical 1D L...
Modeling the evolution of infrared galaxies: A Parametric backwards evolution model
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We aim at modeling the infrared galaxy evolution in an as simple as possible way and reproduce statistical properties among which the number counts between 15 microns and 1.1 mm, the luminosity functi...
We propose a simple procedure for evaluating the main attributes
of a Schwarzschild's black hole: Bekenstein-Hawking entropy, Hawking temperature
and Bekenstein's quantization of the surface area. W...
