Gamma rays from the quasar PKS 1441+25: story of an escape
A. U. Abeysekara, S. Archambault, A. Archer +103
Outbursts from gamma-ray quasars provide insights on the relativistic jets of active galactic nuclei and constraints on the diffuse radiation fields that fill the Universe. The det…
Multiwavelength Study of Quiescent States of Mrk 421 with Unprecedented Hard X-Ray Coverage Provided by NuSTAR in 2013
M. Baloković, D. Paneque, G. Madejski +305
We present coordinated multiwavelength observations of the bright, nearby BL Lac object Mrk 421 taken in 2013 January-March, involving GASP-WEBT, Swift, NuSTAR, Fermi-LAT, MAGIC, V…
Deep XMM Observations of Draco rule out at the 99% Confidence Level a Dark Matter Decay Origin for the 3.5 keV Line
Tesla E. Jeltema, Stefano Profumo
We searched for an X-ray line at energies around 3.5 keV in deep, ~1.6 Msec XMM-Newton observations of the dwarf spheroidal galaxy Draco. No line was found in either the MOS or the…
Chandra counterparts of CANDELS GOODS-S sources
N. Cappelluti, A. Comastri, A. Fontana +18
Improving the capabilities of detecting faint X-ray sources is fundamental to increase the statistics on faint high-z AGN and star-forming galaxies. We performed a simultaneous Max…
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…
Search for Gamma-Ray Lines towards Galaxy Clusters with the Fermi-LAT
B. Anderson, S. Zimmer, J. Conrad +3
We report on a search for monochromatic -ray features in the spectra of galaxy clusters observed by the \emph{Fermi} Large Area Telescope. Galaxy clusters are the largest struct…
Flows of X-ray gas reveal the disruption of a star by a massive black hole
Jon M. Miller, Jelle S. Kaastra, M. Coleman Miller +18
Tidal forces close to massive black holes can violently disrupt stars that make a close approach. These extreme events are discovered via bright X-ray and optical/UV flares in gala…
Putting Things Back Where They Belong: Tracing Cosmic-Ray Injection with H2
Eric Carlson, Tim Linden, Stefano Profumo
At present, all physical models of diffuse Galactic gamma-ray emission assume that the distribution of cosmic-ray sources traces the observed populations of either OB stars, pulsar…
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…
Happy Birthday Swift: Ultra-long GRB141121A and its broad-band Afterglow
A. Cucchiara, P. Veres, A. Corsi +27
We present our extensive observational campaign on the Swift-discovered GRB141121A, al- most ten years after its launch. Our observations covers radio through X-rays, and extends f…
The X-ray through Optical Fluxes and Line Strengths of Tidal Disruption Events
Nathaniel Roth, Daniel Kasen, James Guillochon +1
Observations of luminous flares resulting from the possible tidal disruption of stars by supermassive black holes have raised a number of puzzles. Outstanding questions include the…
Thermonuclear detonations ensuing white dwarf mergers
Marius Dan, James Guillochon, Marcus Brüggen +2
The merger of two white dwarfs (WDs) has for many years not been considered as the favoured model for the progenitor system of type Ia supernovae (SNe Ia). But recent years have se…
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…
The central engine of GRB 130831A and the energy breakdown of a relativistic explosion
M. De Pasquale, S. R. Oates, J. L. Racusin +37
Gamma-ray bursts (GRBs) are the most luminous explosions in the universe, yet the nature and physical properties of their energy sources are far from understood. Very important clu…
First NuSTAR Observations of Mrk 501 within a Radio to TeV Multi-Instrument Campaign
A. Furniss, K. Noda, S. Boggs +273
We report on simultaneous broadband observations of the TeV-emitting blazar Markarian 501 between 1 April and 10 August 2013, including the first detailed characterization of the s…
Search for TeV Gamma-Ray Emission from Point-like Sources in the Inner Galactic Plane with a Partial Configuration of the HAWC Observatory
A. U. Abeysekara, R. Alfaro, C. Alvarez +95
A survey of the inner Galaxy region of Galactic longitude l in [+15, +50] degree and latitude b in [-4,+4] degree is performed using one-third of the High Altitude Water Cherenkov…
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…
