On the origin of X-ray spectra in luminous blazars
Marek Sikora, Mateusz Janiak, Krzysztof Nalewajko +2
Gamma-ray luminosities of some quasar-associated blazars imply jet powers reaching values comparable to the accretion power even if assuming very strong Doppler boosting and very h…
Discovery of GeV Emission from the Circinus galaxy with the Fermi-LAT
Masaaki Hayashida, Lukasz Stawarz, Chi C. Cheung +7
We report the discovery of gamma-ray emission from the Circinus galaxy using the Large Area Telescope (LAT) onboard the Fermi Gamma-ray Space Telescope. Circinus is a nearby (~4 Mp…
First Results from NuSTAR Observations of Mkn 421
M. Baloković, M. Ajello, R. D. Blandford +34
Mkn 421 is a nearby active galactic nucleus dominated at all wavelengths by a very broad non-thermal continuum thought to arise from a relativistic jet seen at a small angle to the…
The Nuclear Spectroscopic Telescope Array (NuSTAR) Mission
Fiona A. Harrison, William W. Craig, Finn E. Christensen +77
The Nuclear Spectroscopic Telescope Array (NuSTAR) mission, launched on 13 June 2012, is the first focusing high-energy X-ray telescope in orbit. NuSTAR operates in the band from 3…
