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…
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…
Standing Shock Instability in Advection-Dominated Accretion Flows
Truong Le, Kent S. Wood, Michael T. Wolff +2
Depending on the values of the energy and angular momentum per unit mass in the gas supplied at large radii, inviscid advection-dominated accretion flows can display velocity profi…
The Transient Accereting X-Ray Pulsar XTE J1946+274: Stability of the X-Ray Properties at Low Flux and Updated Orbital Solution
Diana M. Marcu-Cheatham, Katja Pottschmidt, Matthias Kühnel +19
We present a timing and spectral analysis of the X-ray pulsar XTE J1946+274 observed with Suzaku during an outburst decline in 2010 October and compare with previous results. XTE J…
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…
