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...
Discovery and follow-up studies of the extended, off-plane, VHE gamma-ray source HESS J1507-622
follow-up studies off-plane VHE gamma-ray source HESS J1507-622
2011/1/10
Context: The detection of gamma-rays in the very-high-energy (VHE) range (100 GeV-100 TeV) offers the possibility of studying the parent population of ultrarelativistic particles found in astrophysica...

2011/1/13
Large mosaic multiCCD camera is the key instrument for modern digital sky survey. DECam is an extremely red sensitive 520 Megapixel camera designed for the incoming Dark Energy Survey (DES). It is con...
The Bolocam Galactic Plane Survey IV: 1.1 and 0.35 mm Dust Continuum Emission in the Galactic Center Region
Galactic Plane Survey Galactic Center Region
2010/11/10
The Bolocam Galactic Plane Survey (BGPS) data for a six square degree region of the Galactic plane containing the Galactic center is analyzed and com-pared to infrared and radio continuum data. The BG...

2010/11/11
We estimated the dynamical surface mass density () at the solar Galactocentric distance between 2 and 4 kpc from the Galactic plane, as inferred from the observed kinematics of the thick disk. We fin...

2010/11/16
We present X-ray, infrared, optical and radio observations of four previously unidentified Galactic plane Xray sources, AX J163252–4746, AX J184738–0156, AX J144701–5919 and AX J144547–5931. Detection...
Biases in the Quasar Mass-Luminosity Plane
black hole physics — galaxies evolution — galaxies nuclei — quasars general — accretion accretion discs
2010/11/11
We report that the reported sub-Eddington boundary in the quasar mass-luminosity plane (a departure from the Eddington luminosity limit for the highest quasar black hole masses at a given redshift) is...

We present the Bolocam Galactic Plane Survey (BGPS), a 1.1 mm continuum survey at 3300 e ective resolution of 170 square degrees of the Galactic Plane visible from the northern hemisphere.The BGPS is ...
Dust in the diffuse emission of the galactic plane - The Herschel/Spitzer SED fitting
Galaxy Astrophysics (astro-ph.GA)
2011/1/4
The first Herschel Hi-Gal images of the galactic plane unveil the far-infrared diffuse emission of the interstellar medium with an unprecedented angular resolution and sensitivity. In this paper, we p...
Dynamics of Viscous Dissipative Plane Symmetric Gravitational Collapse
Gravitational collapse Dissipation Junction conditions Dynamical equations Transport equations
2010/3/18
We present dynamical description of gravitational collapse in view of Misner and Sharp's formalism. Matter under consideration is a complicated fluid consistent with plane symmetry which we assume to ...
