Bright radio emission from an ultraluminous stellar-mass microquasar in M31
Matthew J. Middleton, James C. A. Miller-Jones, Sera Markoff +34
A subset of ultraluminous X-ray sources (those with luminosities < 10^40 erg/s) are thought to be powered by the accretion of gas onto black holes with masses of ~5-20 M_solar, pro…
Measurement of the extragalactic background light imprint on the spectra of the brightest blazars observed with H.E.S.S

Binary Millisecond Pulsar Discovery via Gamma-Ray Pulsations
H. J. Pletsch, L. Guillemot, H. Fehrmann +150
Millisecond pulsars, old neutron stars spun-up by accreting matter from a companion star, can reach high rotation rates of hundreds of revolutions per second. Until now, all such "…
The dynamic ejecta of compact object mergers and eccentric collisions
S. Rosswog
Compact object mergers eject neutron-rich matter in a number of ways: by the dynamical ejection mediated by gravitational torques, as neutrino-driven winds and probably also a good…
Search for Galactic PeV Gamma Rays with the IceCube Neutrino Observatory
IceCube collaboration, M. G. Aartsen, R. Abbasi +274
Gamma-ray induced air showers are notable for their lack of muons, compared to hadronic showers. Hence, air shower arrays with large underground muon detectors can select a sample…
Identification of HESS J1303-631 as a Pulsar Wind Nebula through gamma-ray, X-ray and radio observations
The H. E. S. S. Collaboration, :, A. Abramowski +196
The previously unidentified very high-energy (VHE; E > 100 GeV) γ-ray source HESS J1303-631, discovered in 2004, is re-examined including new data from the H.E.S.S. Cherenkov teles…
The Unusually Luminous Extragalactic Nova SN 2010U
Ian Czekala, E. Berger, R. Chornock +10
We present observations of the unusual optical transient SN 2010U, including spectra taken 1.03 days to 15.3 days after maximum light that identify it as a fast and luminous Fe II…
Probing the extent of the non-thermal emission from the Vela X region at TeV energies with H.E.S.S
A. Abramowski, F. Acero, F. Aharonian +196
Vela X is a region of extended radio emission in the western part of the Vela constellation: one of the nearest pulsar wind nebulae (PWNe), and associated with the energetic Vela p…
Observation of Cosmic Ray Anisotropy with the IceTop Air Shower Array
IceCube Collaboration, M. G. Aartsen, R. Abbasi +273
We report on the observation of anisotropy in the arrival direction distribution of cosmic rays at PeV energies. The analysis is based on data taken between 2009 and 2012 with the…

IceCube collaboration, R. Abbasi, Y. Abdou +268
We report on searches for neutrino sources at energies above 200 GeV in the Northern sky of the galactic plane, using the data collected by the South Pole neutrino telescopes IceCu…
The runaway instability in general relativistic accretion disks
O. Korobkin, E. Abdikamalov, N. Stergioulas +4
When an accretion disk falls prey to the runaway instability, a large portion of its mass is devoured by the black hole within a few dynamical times. Despite decades of effort, it…
Supernova 2008J: early time observations of a heavily reddened SN 2002ic-like transient
F. Taddia, M. D. Stritzinger, M. M. Phillips +19
