Internal shocks driven by accretion flow variability in the compact jet of the black hole binary GX 339-4
S. Drappeau, J. Malzac, J. Belmont +2
In recent years, compact jets have been playing a growing role in the understanding of accreting black hole engines. In the case of X-ray binary systems, compact jets are usually a…
The - relation and the internal shock model
R. Mochkovitch, L. Nava
The validity of the - correlation in gamma-ray bursts and the possibility of explaining the prompt emission with internal shocks are highly debated questi…

The pulsar IGR J16393-4643 belongs to a class of highly absorbed supergiant HMXBs, characterised by very high column density of absorbing matter. We present the results of the simu…
Source identification in the IGR J17448-3232 field: discovery of the Scorpius galaxy cluster

We use a 43-ks XMM-Newton observation to investigate the nature of sources first distinguished by a follow-up Chandra observation of the field surrounding INTEGRAL source IGR J1744…
On the radio properties of the intermediate-mass black hole candidate ESO 243-49 HLX-1
D. Cseh, N. A. Webb, O. Godet +8
We present follow-up radio observations of ESO 243-49 HLX-1 from 2012 using the Australia Telescope Compact Array (ATCA) and the Karl G. Jansky Very Large Array (VLA). We report th…
Discovery of the VHE gamma-ray source HESS J1832-093 in the vicinity of SNR G22.7-0.2
H. E. S. S. Collaboration, :, A. Abramowski +218
The region around the supernova remnant (SNR) W41 contains several TeV sources and has prompted the H.E.S.S. Collaboration to perform deep observations of this field of view. This…
A hadronic origin for ultra-high-frequency-peaked BL Lac objects
M. Cerruti, A. Zech, C. Boisson +1
Current Cherenkov telescopes have identified a population of ultra-high-frequency peaked BL Lac objects (UHBLs), also known as extreme blazars, that exhibit exceptionally hard TeV…
Consistent neutron star models with magnetic field dependent equations of state
Debarati Chatterjee, Thomas Elghozi, Jerome Novak +1
We present a self-consistent model for the study of the structure of a neutron star in strong magnetic fields. Starting from a microscopic Lagrangian, this model includes the effec…
The high-energy -ray emission of AP Librae
H. E. S. S. Collaboration, Fermi-LAT collaborations
The -ray spectrum of the low-frequency-peaked BL Lac (LBL) object AP Librae is studied, following the discovery of very-high-energy (VHE; ) -ray emission up…
Comparing the spectral lag of short and long gamma-ray bursts and its relation with the luminosity
M. G. Bernardini, G. Ghirlanda, S. Campana +14
We investigated the rest frame spectral lags of two complete samples of bright long (50) and short (6) gamma-ray bursts (GRB) detected by Swift. We analysed the Swift/BAT data thro…
Search for dark matter annihilation signatures in H.E.S.S. observations of Dwarf Spheroidal Galaxies
H. E. S. S. Collaboration, :, A. Abramowski +229
Dwarf spheroidal galaxies of the Local Group are close satellites of the Milky Way characterized by a large mass-to-light ratio and are not expected to be the site of non-thermal h…
Equilibrium solutions of relativistic rotating stars with mixed poloidal and toroidal magnetic fields
Koji Uryu, Eric Gourgoulhon, Charalampos Markakis +3
Stationary and axisymmetric solutions of relativistic rotating stars with strong mixed poloidal and toroidal magnetic fields are obtained numerically. Because of the mixed componen…
Discovery of X-ray Pulsations from the INTEGRAL Source IGR J11014-6103
J. P. Halpern, J. A. Tomsick, E. V. Gotthelf +6
We report the discovery of PSR J1101-6101, a 62.8 ms pulsar in IGR J11014-6103, a hard X-ray source with a jet and a cometary tail that strongly suggests it is moving away from the…
Circular polarization in the optical afterglow of GRB 121024A
K. Wiersema, S. Covino, K. Toma +37
Gamma-ray bursts (GRBs) are most probably powered by collimated relativistic outflows (jets) from accreting black holes at cosmological distances. Bright afterglows are produced wh…
High-energy gamma-ray and neutrino backgrounds from clusters of galaxies and radio constraints
Fabio Zandanel, Irene Tamborra, Stefano Gabici +1
Cosmic-ray protons accumulate for cosmological times in clusters of galaxies as their typical radiative and diffusive escape times are longer than the Hubble time. Their hadronic i…
