Origin of Fe nuclei in cosmic rays: the contribution of local OB associations
Nicolas de Séréville, Vincent Tatischeff, Pierre Cristofari +2
The presence of live Fe nuclei (lifetime of 3.8~Myr) in cosmic rays detected by the ACE/CRIS instrument suggests a nearby nucleosynthesis source. Fe is primarily prod…
The e-ASTROGAM gamma-ray space mission
V. Tatischeff, M. Tavani, P. von Ballmoos +48
The e-ASTROGAM is a gamma-ray space mission to be proposed as the M5 Medium-size mission of the European Space Agency. It is dedicated to the observation of the Universe with unpre…
Soft X-ray absorption excess in gamma-ray burst afterglow spectra: Absorption by turbulent ISM
M. Tanga, P. Schady, A. Gatto +5
Two-thirds of long duration gamma-ray bursts (GRBs) show soft X-ray absorption in excess of the Milky Way. The column densities of metals inferred from UV and optical spectra diffe…
How did globular clusters lose their gas?
C. Charbonnel, M. Krause, T. Decressin +3
We summarize the results presented in Krause et al. (2012) on the impact of supernova-driven shells and dark-remnant accretion on gas expulsion in globular cluster infancy.
Quasi-Periodic Pulsations in Solar Flares: new clues from the Fermi Gamma-Ray Burst Monitor
D. Gruber, P. Lachowicz, E. Bissaldi +14
In the last four decades it has been observed that solar flares show quasi-periodic pulsations (QPPs) from the lowest, i.e. radio, to the highest, i.e. gamma-ray, part of the elect…
Rest-frame properties of 32 gamma-ray bursts observed by the Fermi Gamma-Ray Burst Monitor
D. Gruber, J. Greiner, A. von Kienlin +27
Aims: In this paper we study the main spectral and temporal properties of gamma-ray bursts (GRBs) observed by Fermi/GBM. We investigate these key properties of GRBs in the rest-fra…
Particle Acceleration in Cosmic Sites - Astrophysics Issues in our Understanding of Cosmic Rays
Roland Diehl
Laboratory experiments to explore plasma conditions and stimulated particle acceleration can illuminate aspects of the cosmic particle acceleration process. Here we discuss the cos…
SPI/INTEGRAL observation of the Galactic central radian: contribution of discrete sources and implication for the diffuse emission
L. Bouchet, J. P. Roques, P. Mandrou +4
The INTEGRAL observatory has been performing a deep survey of the Galactic central radian since 2003, with the goal of both extracting a catalog of sources and gaining insight into…
SPI Measurements of Galactic 26Al
R. Diehl, J. Knödlseder, G. Lichti +7
The precision measurement of the 1809 keV gamma-ray line from Galactic Al is one of the goals of the SPI spectrometer on INTEGRAL with its Ge detector camera. We aim for det…
COMPTEL upper limits for the 56Co gamma-ray emission from SN1998bu
R. Georgii, S. Plüschke, R. Diehl +6
Supernova 1998bu in the galaxy M96 was observed by COMPTEL for a total of 88 days starting 17 days after the explosion. We searched for a signal in the 847 keV and 1238 keV lines o…
The Crab pulsar in the 0.75-30 MeV range as seen by CGRO COMPTEL
L. Kuiper, W. Hermsen, G. Cusumano +5
We present the time-averaged characteristics of the Crab pulsar in the 0.75-30 MeV energy window using data from the imaging Compton Telescope COMPTEL aboard the Compton Gamma-Ray…
Gamma-Ray Line Emission from Superbubbles in the Interstellar Medium: The Cygnus Region
S. Plueschke, R. Diehl, K. Kretschmer +2
The star forming process in the Milky Way is non-uniform in time and space. The scale of star forming regions ranges from groups within a few pc to large segments of spiral arms wi…
Tests of Galactic Cosmic Ray Source Models
L O'C Drury, D C Ellison, F A Aharonian +9
This report discusses the possibilities for observational tests of current models and ideas regarding the origin of the Galactic Cosmic Rays using facilities which are already avai…
Radioactivities in Population Studies: 26Al and 60Fe from OB Associations
S. Plueschke, R. Diehl, K. Kretschmer +2
The observation of the interstellar 1.809 MeV decay-line of radioactive 26Al by the imaging gamma-ray telescope COMPTEL have let to the conclusion, that massive stars and their sub…
The first COMPTEL Source Catalogue
V. Schoenfelder, the COMPTEL Collaboration
The imaging Compton telescope COMPTEL aboard NASA's Compton Gamma-Ray Observatory has opened the MeV gamma-ray band as a new window to astronomy. COMPTEL provided the first complet…
26Al in the local interstellar medium
J. Knoedlseder, K. Bennett, H. Bloemen +6
We estimate the 1.8 MeV luminosity of the Sco-Cen association due to radioactive decay of 26Al to (4-15) 10e-5 ph cm**-2 s**-1. We propose a low surface brightness, limb brightened…
Constraints from Al Measurements on the Galaxy's Recent Global Star Formation Rate and Core Collapse Supernovae Rate
F. X. Timmes, R. Diehl, D. H. Hartmann
Gamma-rays from the decay of Al offer a stringent constraint on the Galaxy's global star formation rate over the past million years, supplementing other methods for quantify…
