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…
Investigation of Primordial Black Hole Bursts using Interplanetary Network Gamma-ray Bursts
T. N. Ukwatta, K. Hurley, J. H MacGibbon +22
The detection of a gamma-ray burst (GRB) in the solar neighborhood would have very important implications for GRB phenomenology. The leading theories for cosmological GRBs would no…
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…
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…
Primordial Black Holes: Observational Characteristics of The Final Evaporation
T. N. Ukwatta, D. R. Stump, J. T. Linnemann +4
Many early universe theories predict the creation of Primordial Black Holes (PBHs). PBHs could have masses ranging from the Planck mass to 10^5 solar masses or higher depending on…
