Science with e-ASTROGAM (A space mission for MeV-GeV gamma-ray astrophysics)
A. De Angelis, V. Tatischeff, I. A. Grenier +248
e-ASTROGAM (enhanced ASTROGAM) is a breakthrough Observatory space mission, with a detector composed by a Silicon tracker, a calorimeter, and an anticoincidence system, dedicated t…
Magnetar nebulae can be rotationally powered
D. F. Torres
A wind nebula generating extended X-ray emission was recently detected surrounding Swift 1834.9-0846. This is the first magnetar for which such a (pulsar) wind nebula (PWN) was fou…
MAGIC VHE Gamma-Ray Observations Of Binary Systems
Daniela Hadasch, Wlodek Bednarek, Oscar Blanch +13
There are several types of Galactic sources that can potentially accelerate charged particles up to GeV and TeV energies. We present here the results of our observations of the sou…
Constraining Lorentz invariance violation using the Crab Pulsar emission observed up to TeV energies by MAGIC
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +142
Spontaneous breaking of Lorentz symmetry at energies on the order of the Planck energy or lower is predicted by many quantum gravity theories, implying non-trivial dispersion relat…
Performance of the MAGIC telescopes under moonlight
D. Guberman, P. Colin
MAGIC, a system of two imaging atmospheric Cherenkov telescopes, achieves its best performance under dark conditions, i.e. in absence of moonlight or twilight. Since operating the…
GeV detection of HESS J0632+057
Jian Li, Diego F. Torres, K. -S. Cheng +4
HESS J0632+057 is the only gamma-ray binary that has been detected at TeV energies, but not at GeV energies yet. Based on nearly nine years of Fermi Large Area Telescope (LAT) Pass…
MAGIC observations of the microquasar V404 Cygni during the 2015 outburst
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +142
The microquasar V404 Cygni underwent a series of outbursts in 2015, June 15-31, during which its flux in hard X-rays (20-40 keV) reached about 40 times the Crab Nebula flux. Becaus…
Observation of the Black Widow B1957+20 millisecond pulsar binary system with the MAGIC telescopes
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +145
B1957+20 is a millisecond pulsar located in a black widow type compact binary system with a low mass stellar companion. The interaction of the pulsar wind with the companion star w…
Cosmic-ray electron+positron spectrum from 7 GeV to 2 TeV with the Fermi Large Area Telescope
LAT Collaboration, S. Abdollahi, M. Ackermann +97
We present a measurement of the cosmic-ray electron+positron spectrum between 7 GeV and 2 TeV performed with almost seven years of data collected with the Fermi Large Area Telescop…
Prospects for CTA observations of the young SNR RX J1713.7-3946
The CTA Consortium, :, F. Acero +381
We perform simulations for future Cherenkov Telescope Array (CTA) observations of RX~J1713.73946, a young supernova remnant (SNR) and one of the brightest sources ever discovere…
The Fermi Galactic Center GeV Excess and Implications for Dark Matter
LAT Collaboration
The region around the Galactic center (GC) is now well established to be brighter at energies of a few GeV than expected from conventional models of diffuse gamma-ray emission and…
Performance of the MAGIC telescopes under moonlight
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +143
MAGIC, a system of two imaging atmospheric Cherenkov telescopes, achieves its best performance under dark conditions, i.e. in absence of moonlight or twilight. Since operating the…
First Multi-wavelength Campaign on the Gamma-ray-loud Active Galaxy IC 310
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +160
The extragalactic VHE gamma-ray sky is rich in blazars. These are jetted active galactic nuclei viewed at a small angle to the line-of-sight. Only a handful of objects viewed at a…
An XMM-Newton and INTEGRAL view on the hard state of EXO 1745-248 during its 2015 outburst
M. Matranga, A. Papitto, T. Di Salvo +10
CONTEXT - Transient low-mass X-ray binaries (LMXBs) often show outbursts lasting typically a few-weeks and characterized by a high X-ray luminosity (…
Search for Cosmic-Ray Electron and Positron Anisotropies with Seven Years of Fermi Large Area Telescope Data
LAT Collaboration
The Large Area Telescope on board the Fermi Gamma-ray Space Telescope has collected the largest ever sample of high-energy cosmic-ray electron and positron events since the beginni…
MAGIC detection of very high energy gamma-ray emission from the low-luminosity blazar 1ES 1741+196
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +159
We present the first detection of the nearby (z=0.084) low-luminosity BL Lac object 1ES 1741+196 in the very high energy (VHE: E100 GeV) band. This object lies in a triplet of i…
Fermi-LAT Observations of High-energy Behind-the-limb Solar Flares
