We study the change in cosmic-ray pressure, the change in cosmic-ray density, and the level of cosmic-ray induced heating via Alfven-wave damping when cosmic rays move from a hot ionized plasma to a c...
Diffuse emission measurement with INTEGRAL/SPI as indirect probe of cosmic-ray electrons and positrons
Galaxy: general ?Galaxy structure ?gamma rays observations
2011/8/24
Significant advances have been made in the understanding of the diffuse Galactic hard X-ray continuum emission using data from the INTEGRAL observatory. The diffuse hard power-law component seen with ...
"Discrepant hardenings" in cosmic ray spectra: a first estimate of the effects on secondary antiproton and diffuse gamma-ray yields
Discrepant hardenings cosmic ray spectra the effects on secondary antiproton
2011/1/11
Recent data from CREAM seem to confirm early suggestions that primary cosmic ray spectra at few TeV/nucleon are harder than in the 10-100 GeV range. Also, helium and heavier nuclei spectra appear syst...
Studies of Diffuse Interstellar Bands. V. Pairwise Correlations of Eight Strong DIBs and Neutral Hydrogen, Molecular Hydrogen, and Color Excess
ISM lines and bands − ISM molecules
2010/11/15
We establish correlations between equivalent widths of eight diffuse interstel-lar bands (DIBs), and examine their correlations with atomic hydrogen, molec-ular hydrogen, and EB−V . The DIBs are...
Identification of H$_2$CCC as a diffuse interstellar band carrier
general lines and bands ISM molecules methods laboratory techniques spectroscopic
2010/11/9
We present strong evidence that the broad, di use interstellar bands (DIBs) at 4881 and
5450A are caused by the B 1B1 X 1A1 transition of H2CCC (l-C3H2). The large widths of the
bands are due to th...
A survey of diffuse interstellar bands in the Andromeda galaxy: optical spectroscopy of M31 OB stars

2010/11/10
We present the largest sample to-date of intermediate-resolution blue-to-red optical spectra of B-type supergiants in M31 and undertake the first survey of diffuse interstellar bands (DIBs) in this ga...
Diffuse Hard X-ray Emission in Starburst Galaxies as Synchrotron from Very High Energy Electrons
High Energy Astrophysical Phenomena (astro-ph.HE) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
The origin of the diffuse hard X-ray emission of starburst galaxies is a long-standing problem. We suggest that synchrotron emission of 10 - 100 TeV electrons and positrons can contribute significantl...
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...
Diffuse light and galaxy interactions in the core of nearby clusters
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
The kinematics of the diffuse light in the densest regions of the nearby clusters can be unmasked using the planetary nebulae (PNs) as probes of the stellar motions.
