Unveiling the Gamma-ray Source Count Distribution Below the Fermi Detection Limit with Photon Statistics
Hannes-S. Zechlin, Alessandro Cuoco, Fiorenza Donato +2
The source-count distribution as a function of their flux, dN/dS, is one of the main quantities characterizing gamma-ray source populations. We employ statistical properties of the…
Radio detection prospects for a bulge population of millisecond pulsars as suggested by Fermi LAT observations of the inner Galaxy
Francesca Calore, Mattia Di Mauro, Fiorenza Donato +2
Analogously to globular clusters, the dense stellar environment of the Galactic center has been proposed to host a large population of as-yet undetected millisecond pulsars (MSPs).…
Sensitivity of the JEM-EUSO telescope to gravity effects in neutrino-induced air showers
Stefan Mladenov, Galina Vankova, Roumen Tsenov +2
We examine the JEM-EUSO sensitivity to gravity effects in the context of Randall-Sundrum (RS) model with a single extra dimension and small curvature of the metric. Exchanges of re…
4.5 years multi-wavelength observations of Mrk 421 during the ARGO-YBJ and Fermi common operation time
B. Bartoli, P. Bernardini, X. J. Bi +68
We report on the extensive multi-wavelength observations of the blazar Markarian 421 (Mrk 421) covering radio to gamma-rays, during the 4.5 year period of ARGO-YBJ and Fermi common…
The 1st Fermi Lat Supernova Remnant Catalog
Fabio Acero, Markus Ackermann, Marco Ajello +156
To uniformly determine the properties of supernova remnants (SNRs) at high energies, we have developed the first systematic survey at energies from 1 to 100 GeV using data from 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…
The Extragalactic Gamma-ray Sky in the Fermi era
F. Massaro, D. J. Thompson, E. C. Ferrara
The Universe is largely transparent to rays in the GeV energy range, making these high-energy photons valuable for exploring energetic processes in the cosmos. After seven year…
Multiwavelength Evidence for Quasi-periodic Modulation in the Gamma-ray Blazar PG 1553+113
The Fermi LAT collaboration, M. Ackermann, M. Ajello +139
We report for the first time a gamma-ray and multi-wavelength nearly-periodic oscillation in an active galactic nucleus. Using the Fermi Large Area Telescope (LAT) we have discover…
Search for extended gamma-ray emission from the Virgo galaxy cluster with Fermi-LAT
M. Ackermann, M. Ajello, A. Albert +118
Galaxy clusters are one of the prime sites to search for dark matter (DM) annihilation signals. Depending on the substructure of the DM halo of a galaxy cluster and the cross secti…
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…
Prospects for Indirect Dark Matter Searches with the Cherenkov Telescope Array (CTA)
J. Carr, C. Balazs, T. Bringmann +20
The Cherenkov Telescope Array (CTA) will have a unique chance of discovery for a large range of masses in Weakly Interacting Massive Particles models of dark matter. The principal…
2FHL: The Second Catalog of Hard Fermi-LAT Sources
LAT Collaboration
We present a catalog of sources detected above 50 GeV by the {\it Fermi}-Large Area Telescope (LAT) in 80 months of data. The newly delivered Pass 8 event-level analysis allows the…
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…
Classical and relativistic conservation of momentum flux in radio-galaxies
L. Zaninetti
A new set of laws of motion for turbulent jets propagating in an intergalactic medium characterized by a decreasing density is derived by applying conservation of momentum flux bot…

The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +448
The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared…
