NuSTAR/XMM-Newton monitoring of the Seyfert 1 galaxy HE 1143-1810. Testing the two-corona scenario
F. Ursini, P. -O. Petrucci, S. Bianchi +11
We test the two-corona accretion scenario for active galactic nuclei in the case of the `bare' Seyfert 1 galaxy HE 1143-1810. We perform a detailed study of the broad-band UV--X-ra…

Gamma-ray bursts (GRBs) are brief flashes of gamma rays, considered to be the most energetic explosive phenomena in the Universe. The emission from GRBs comprises a short (typicall…
Physical constraints from near-infrared fast photometry of the black-hole transient GX 339-4
F. M. Vincentelli, P. Casella, P. Petrucci +9
We present results from the first multi-epoch X-ray/IR fast-photometry campaign on the black-hole transient GX 339--4, during its 2015 outburst decay. We studied the evolution of t…
H.E.S.S. detection of very-high-energy gamma-ray emission from the quasar PKS 0736+017
H. E. S. S. Collaboration, :, H. Abdalla +225
Flat-spectrum radio-quasars (FSRQs) are rarely detected at very-high-energies (VHE; E>100 GeV) due to their low-frequency-peaked SEDs. At present, only 6 FSRQs are known to emit VH…
Incoherent fast variability of X-ray obscurers. The case of NGC 3783
B. De Marco, T. P. Adhikari, G. Ponti +22
Context. Obscuration events caused by outflowing clumps or streams of high column density, low ionisation gas, heavily absorbing the X-ray continuum, have been witnessed in a numbe…
Magnetically-driven jets and winds from weakly magnetized accretion disks
J. Jacquemin-Ide, J. Ferreira, G. Lesur
Semi-analytical models of disk outflows have successfully described magnetically-driven, self-confined super-Alfvénic jets from near Keplerian accretion disks. These Jet Emitting D…
NuSTAR observations of the unidentified INTEGRAL sources: constraints on the Galactic population of HMXBs

The NuSTAR Legacy program 'Unidentified INTEGRAL sources' targeted faint hard X-ray sources revealed by INTEGRAL in the Galactic plane in order to provide conclusive identification…
Proton acceleration in pulsar magnetospheres
C. Guépin, B. Cerutti, K. Kotera
Pulsars have been identified as good candidates for the acceleration of cosmic rays, up to ultra-high energies. However, a precise description of the acceleration processes at play…
The impact of thermal winds on the outburst lightcurves of black hole X-ray binaries
G. Dubus, C. Done, B. E. Tetarenko +1
The observed signatures of winds from X-ray binaries are broadly consistent with thermal winds, driven by X-ray irradiation of the outer accretion disc. Thermal winds produce mass…
Discovery of the Galactic High-Mass Gamma-ray Binary 4FGL J1405.1-6119
R. H. D. Corbet, L. Chomiuk, M. J. Coe +8
We report the identification from multi-wavelength observations of the Fermi Large Area Telescope (LAT) source 4FGL J1405.1-6119 (= 3FGL J1405.4-6119) as a high-mass gamma-ray bina…
Relations between phenomenological and physical parameters in the hot coronae of AGNs computed with the MoCA code
R. Middei, S. Bianchi, A. Marinucci +4
The primary X-ray emission in active galactic nuclei (AGNs) is widely believed to be due to Comptonisation of the thermal radiation from the accretion disc in a corona of hot elect…
