Very-high-energy gamma-rays from the Universe's middle age: detection of the z=0.940 blazar PKS 1441+25 with MAGIC
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +246
The flat-spectrum radio quasar PKS 1441+25 at a redshift of z = 0.940 is detected between 40 and 250 GeV with a significance of 25.5 σ using the MAGIC telescopes. Together with the…
Fermi-LAT Observations of High-Energy Gamma-Ray Emission Toward the Galactic Center
LAT Collaboration
The Fermi Large Area Telescope (LAT) has provided the most detailed view to date of the emission towards the Galactic centre (GC) in high-energy gamma-rays. This paper describes th…
Resolving the Extragalactic -ray Background above 50 GeV with Fermi-LAT
LAT Collaboration
The Fermi Large Area Telescope (LAT) Collaboration has recently released a catalog of 360 sources detected above 50 GeV (2FHL). This catalog was obtained using 80 months of data re…
Very high energy gamma-ray follow-up observations of novae and dwarf novae with the MAGIC telescopes
R. López-Coto, J. Sitarek, W. Bednarek +4
In the last few years the Fermi-LAT instrument has detected GeV gamma-ray emission from several novae. Such GeV emission can be interpreted in terms of inverse Compton emission fro…
INFN Camera demonstrator for the Cherenkov Telescope Array
G. Ambrosi, M. Ambrosio, C. Aramo +46
The Cherenkov Telescope Array is a world-wide project for a new generation of ground-based Cherenkov telescopes of the Imaging class with the aim of exploring the highest energy re…
Deep view of the Large Magellanic Cloud with 6 years of Fermi-LAT observations
LAT Collaboration
The nearby Large Magellanic Cloud (LMC) provides a rare opportunity of a spatially resolved view of an external star-forming galaxy in gamma-rays. The LMC was detected at 0.1-100Ge…
Very-high-energy γ-ray observations of novae and dwarf novae with the MAGIC telescopes
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +148
Context. In the last five years the Fermi Large Area Telescope (LAT) instrument detected GeV γ-ray emission from five novae. The GeV emission can be interpreted in terms of an inve…
PSR J1906+0722: An Elusive Gamma-ray Pulsar
C. J. Clark, H. J. Pletsch, J. Wu +117
We report the discovery of PSR J1906+0722, a gamma-ray pulsar detected as part of a blind survey of unidentified Fermi Large Area Telescope (LAT) sources being carried out on the v…
Search for Gamma-ray Production in Supernovae Located in a Dense Circumstellar Medium with the Fermi-LAT
A. Franckowiak, K. Murase, E. O. Ofek
Supernovae (SNe) exploding in a dense circumstellar medium (CSM) are predicted to accelerate cosmic rays in collisionless shocks and emit GeV gamma rays and TeV neutrinos on a time…
Search for Early Gamma-ray Production in Supernovae Located in a Dense Circumstellar Medium with the Fermi LAT
M. Ackermann, I. Arcavi, L. Baldini +108
Supernovae (SNe) exploding in a dense circumstellar medium (CSM) are hypothesized to accelerate cosmic rays in collisionless shocks and emit GeV gamma rays and TeV neutrinos on a t…
Updated Search for Spectral Lines from Galactic Dark Matter Interactions with Pass 8 Data from the Fermi Large Area Telescope
LAT Collaboration
Dark matter in the Milky Way may annihilate directly into gamma rays, producing a monoenergetic spectral line. Therefore, detecting such a signature would be strong evidence for da…
Searching for Dark Matter Annihilation from Milky Way Dwarf Spheroidal Galaxies with Six Years of Fermi-LAT Data
LAT Collaboration
The dwarf spheroidal satellite galaxies (dSphs) of the Milky Way are some of the most dark matter (DM) dominated objects known. We report on gamma-ray observations of Milky Way dSp…
Very high energy gamma-ray follow-up observations of novae and dwarf novae with the MAGIC telescopes
J. Sitarek, W. Bednarek, R. Lopez-Coto +1
In the last few years the Fermi -LAT instrument has detected GeV gamma-ray emission from a few novae. Such GeV emission can be interpreted in terms of an inverse Compton process of…
Analysis of the Impulsive Phase of Solar Flares with Pass 8 LAT data
R. Desiante, F. Longo, N. Omodei +2
We show the results of analyses performed on high-energy gamma-ray emission during the impulsive phase of solar flares detected by the LAT using Pass 8 data. We compare results obt…
