The distribution of radioactive Ti in Cassiopeia A
Brian W. Grefenstette, Chris L. Fryer, Fiona A. Harrison +28
The distribution of elements produced in the inner-most layers of a supernova explosion is a key diagnostic for studying the collapse of massive stars. Here we present the results…
The e-ASTROGAM mission (exploring the extreme Universe with gamma rays in the MeV-GeV range)
Alessandro De Angelis, Vincent Tatischeff, Marco Tavani +71
e-ASTROGAM (`enhanced ASTROGAM') is a breakthrough Observatory mission dedicated to the study of the non-thermal Universe in the photon energy range from 0.3 MeV to 3 GeV. The miss…
First flight of the Gamma-Ray Imager/Polarimeter for Solar flares (GRIPS) instrument
Nicole Duncan, P. Saint-Hilaire, A. Y. Shih +16
The Gamma-Ray Imager/Polarimeter for Solar flares (GRIPS) is a balloon-borne telescope designed to study solar-flare particle acceleration and transport. We describe GRIPS's first…
First NuSTAR observations of the BL Lac - type blazar PKS~2155-304: constraints on the jet content and distribution of radiating particles
G. M. Madejski, K. Nalewajko, K. K. Madsen +35
We report the first hard X-ray observations with NuSTAR of the BL Lac type blazar PKS 2155-304, augmented with soft X-ray data from XMM-Newton and gamma-ray data from the Fermi Lar…
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…
NuSTAR Hard X-ray Survey of the Galactic Center Region II: X-ray Point Sources
JaeSub Hong, Kaya Mori, Charles J. Hailey +41
We present the first survey results of hard X-ray point sources in the Galactic Center (GC) region by NuSTAR. We have discovered 70 hard (3-79 keV) X-ray point sources in a 0.6 deg…
