Absorption lines from magnetically-driven winds in X-ray binaries
S. Chakravorty, P-O. Petrucci, J. Ferreira +8
High resolution X-ray spectra of black hole X-ray binaries (BHBs) show blueshifted absorption lines from disk winds which seem to be equatorial. Winds occur in the Softer (disk-dom…
Modeling high-energy pulsar lightcurves from first principles
Benoît Cerutti, Alexander A. Philippov, Anatoly Spitkovsky
Current models of gamma-ray lightcurves in pulsars suffer from large uncertainties on the precise location of particle acceleration and radiation. Here, we present an attempt to al…
High-energy monitoring of Seyfert galaxies: the case of NGC 4593
F. Ursini, P. -O. Petrucci, G. Matt +6
We discuss preliminary results from a joint XMM-Newton and NuSTAR monitoring program on the active galactic nucleus NGC 4593, consisting of 5x20 ks observations, spaced by two days…
Anatomy of the AGN in NGC 5548: V. A clear view of the X-ray narrow emission lines
M. Whewell, G. Branduardi-Raymont, J. S. Kaastra +15
Context. Our consortium performed an extensive multi-wavelength campaign of the nearby Seyfert 1 galaxy NGC 5548 in 2013-14. The source appeared unusually heavily absorbed in the s…
Variation of bulk Lorentz factor in AGN jets due to Compton rocket in a complex photon field
Thomas Vuillaume, Gilles Henri, Pierre-Olivier Petrucci
Radio-loud active galactic nuclei are among the most powerful objects in the universe. In these objects, most of the emission comes from relativistic jets getting their power from…
Shining in the Dark: the Spectral Evolution of the First Black Holes
Fabio Pacucci, Andrea Ferrara, Marta Volonteri +1
Massive Black Hole (MBH) seeds at redshift are now thought to be key ingredients to explain the presence of the super-massive () bla…
Anatomy of the AGN in NGC 5548 IV. The short-term variability of the outflows
L. Di Gesu, E. Costantini, J. Ebrero +16
During an extensive multiwavelength campaign that we performed in 2013-14 the prototypical Seyfert 1 galaxy NGC 5548 has been found in an unusual condition of heavy and persistent…
Modelling the high-energy emission from gamma-ray binaries using numerical relativistic hydrodynamics
Guillaume Dubus, Astrid Lamberts, Sébastien Fromang
Detailed modeling of the high-energy emission from gamma-ray binaries has been propounded as a path to pulsar wind physics. Fulfilling this ambition requires a coherent model of th…
Infrared study of H1743-322 in outburst: a radio-quiet and NIR-dim microquasar
S. Chaty, A. J. Muñoz Arjonilla, G. Dubus
The X-ray binary, black hole candidate, and microquasar H1743-322 exhibited a series of X-ray outbursts between 2003 and 2008. We took optical/infrared (OIR) observations with the…
Discovery of variable VHE gamma-ray emission from the binary system 1FGL J1018.6-5856
H. E. S. S. Collaboration, :, A. Abramowski +230
Re-observations with the H.E.S.S. telescope array of the very-high-energy (VHE) source HESS J1018-589 A coincident with the Fermi-LAT -ray binary 1FGL J1018.6-5856 have resulted…
Constraints on an Annihilation Signal from a Core of Constant Dark Matter Density around the Milky Way Center with H.E.S.S
HESS Collaboration, A. Abramowski, F. Aharonian +223
An annihilation signal of dark matter is searched for from the central region of the Milky Way. Data acquired in dedicated ON/OFF observations of the Galactic center region with H.…
X-ray Transients: Hyper- or Hypo-Luminous?
Jean-Pierre Lasota, Andrew R. King, Guillaume Dubus
The disk instability picture gives a plausible explanation for the behavior of soft X-ray transient systems if self-irradiation of the disk is included. We show that there is a sim…
The 2012 flare of PG 1553+113 seen with H.E.S.S. and Fermi-LAT
A. Abramowski, F. Aharonian, F. Ait Benkhali +224
Very high energy (VHE, 100 GeV) -ray flaring activity of the high-frequency peaked BL Lac object \pg\ has been detected by the \hess\ telescopes. The flux of the source incr…
Anatomy of the AGN in NGC 5548: III. The high-energy view with NuSTAR and INTEGRAL
F. Ursini, R. Boissay, P. -O. Petrucci +15
We describe the analysis of the seven broad-band X-ray continuum observations of the archetypal Seyfert 1 galaxy NGC 5548 that were obtained with XMM-Newton or Chandra, simultaneou…
Anatomy of the AGN in NGC 5548: I. A global model for the broadband spectral energy distribution
M. Mehdipour, J. S. Kaastra, G. A. Kriss +24
An extensive multi-satellite campaign on NGC 5548 has revealed this archetypal Seyfert-1 galaxy to be in an exceptional state of persistent heavy absorption. Our observations taken…
