A NuSTAR observation of the center of the Coma Cluster
F. Gastaldello, D. R. Wik, S. Molendi +13
We present the results of a 55ks NuSTAR observation of the core of the Coma Cluster. The global spectrum can be explained by thermal gas emission, with a conservative 90% upper lim…
Reconciling models of luminous blazars with magnetic fluxes determined by radio core shift measurements
Krzysztof Nalewajko, Marek Sikora, Mitchell C. Begelman
Estimates of magnetic field strength in relativistic jets of active galactic nuclei (AGN), obtained by measuring the frequency-dependent radio core location, imply that the total m…
The spectrum of isotropic diffuse gamma-ray emission between 100 MeV and 820 GeV
The Fermi LAT collaboration, M. Ackermann, M. Ajello +142
The γ-ray sky can be decomposed into individually detected sources, diffuse emission attributed to the interactions of Galactic cosmic rays with gas and radiation fields, and a res…
X-ray cavities in a sample of 83 SPT-selected clusters of galaxies: Tracing the evolution of AGN feedback in clusters of galaxies out to z=1.2
J. Hlavacek-Larrondo, M. McDonald, B. A. Benson +16
X-ray cavities are key tracers of mechanical (or radio mode) heating arising from the active galactic nuclei (AGN) in brightest cluster galaxies. We report on a survey for X-ray ca…
The Optical Luminosity Function of Gamma-ray Bursts deduced from ROTSE-III Observations
X. H. Cui, X. F. Wu, J. J. Wei +16
We present the optical luminosity function (LF) of gamma-ray bursts (GRBs) estimated from a uniform sample of 58 GRBs from observations with the Robotic Optical Transient Search Ex…
Time-correlation between the radio and gamma-ray activity in blazars and the production site of the gamma-ray emission
W. Max-Moerbeck, T. Hovatta, J. L. Richards +12
In order to determine the location of the gamma-ray emission site in blazars, we investigate the time-domain relationship between their radio and gamma-ray emission. Light-curves f…
The NuSTAR View of Nearby Compton-thick AGN: The Cases of NGC 424, NGC 1320 and IC 2560

We present X-ray spectral analyses for three Seyfert 2 active galactic nuclei, NGC 424, NGC 1320, and IC 2560, observed by NuSTAR in the 3-79 keV band. The high quality hard X-ray…
The Spectrum and Morphology of the Fermi Bubbles
LAT Collaboration
The Fermi bubbles are two large structures in the gamma-ray sky extending to above and below the Galactic center. We analyze 50 months of Fermi Large Area Telescope data…
