2011/10/8
We report far-infrared (FIR) imaging of the Seyfert 2 galaxy NGC 3081 in the range 70-500 micron, obtained with an unprecedented angular resolution, using the Herschel Space Observatory instruments PA...
The Mass Distribution of the Great Attractor as Revealed by a Deep NIR Survey
Distribution Great Attractor Revealed Deep Survey
2011/9/28
This paper presents the analysis of a deep near-infrared J,H,Ks-imaging survey (37.5 sq deg) aimed at tracing the galaxy distribution of the Great Attractor (GA) in the Zone of Avoidance along the so-...
Evidence for mild deviation from power-law distribution of electrons in relativistic shocks: GRB 090902B
radiation mechanisms: non-thermal - methods: analytical - methods: numerical- gamma-rays: bursts, theory - gamma-ray burst: individual: GRB090902B
2011/9/29
Many previous studies have determined that the long lasting emission at X-ray, optical and radio wavelengths from gamma-ray bursts (GRBs), called the afterglow, is likely produced by the external forw...

Distribution High Mass X-ray Binaries Milky Way
2011/9/27
The INTEGRAL satellite, observing the sky at high energy, has quadrupled the number of supergiant X-ray Binaries known in the Galaxy and has revealed new populations of previously hidden High Mass X-r...
Evolution of the Distribution of Neutron Exposures in the Galaxy Disc: An Analytical Model
Nucleosynthesis—neutron exposures—abundances—stars AGB stars low-mass stars—galaxy evolution
2010/9/16
In this work, based on the analytical model with delayed production approximation developed by Pagel & Tautvaiˇsien˙e (1995) for the Galaxy, the analytic solutions of the distribution of neutron expos...
