Gamma-Ray emission from SN2014J near maximum optical light
J. Isern, P. Jean, E. Bravo +17
The optical light curve of Type Ia supernovae (SNIa) is powered by thermalized gamma-rays produced by the decay of 56Ni and 56Co, the main radioactive isotopes synthesized by the t…
Observation of SN2011fe with INTEGRAL. I. Pre--maximum phase
J. Isern, P. Jean, E. Bravo +19
SN2011fe was detected by the Palomar Transient Factory on August 24th 2011 in M101 a few hours after the explosion. From the early optical spectra it was immediately realized that…
The sky distribution of 511 keV positron annihilation line emission as measured with INTEGRAL/SPI
G. Weidenspointner, J. Knoedlseder, P. Jean +10
The imaging spectrometer SPI on board ESA's INTEGRAL observatory provides us with an unprecedented view of positron annihilation in our Galaxy. The first sky maps in the 511 keV an…
The sky distribution of positronium annihilation continuum emission measured with SPI/INTEGRAL
G. Weidenspointner, C. R. Shrader, J. Knoedlseder +15
We present a measurement of the sky distribution of positronium (Ps) annihilation continuum emission obtained with the SPI spectrometer on board ESA's INTEGRAL observatory. The onl…
The all-sky distribution of 511 keV electron-positron annihilation emission
J. Knödlseder, P. Jean, V. Lonjou +11
We present a map of 511 keV electron-positron annihilation emission, based on data accumulated with the SPI spectrometer aboard ESA's INTEGRAL gamma-ray observatory, that covers ap…
SPI observations of positron annihilation radiation from the 4th galactic quadrant: sky distribution
G. Weidenspointner, V. Lonjou, J. Knoedlseder +14
During its first year in orbit the INTEGRAL observatory performed deep exposures of the Galactic Center region and scanning observations of the Galactic plane. We report on the sta…
