H. E. S. S. Collaboration, H. Abdalla, R. Adam +222
PSR B1259-63/LS 2883 is a gamma-ray binary system consisting of a pulsar in an eccentric orbit around a bright Oe stellar-type companion star that features a dense circumstellar di…
Diagnosing pulsar winds in black-widow, redback, and other binary millisecond pulsar systems
Anne Zilles, Kumiko Kotera, Rene Rohrmann +1
Binary systems composed of a recycled millisecond pulsar and a stellar companion in close orbit could be excellent sites to diagnose pulsar winds. In such systems, the pulsar outfl…
Modeling spectral lags in active galactic nucleus flares in the context of Lorentz invariance violation searches
Perennes Cédric, Sol Hélène, Bolmont Julien
High-energy photons emitted by flaring active galactic nuclei (AGNs) have been used for many years to constrain modified dispersion relations in vacuum encountered in the context o…
A very-high-energy component deep in the Gamma-ray Burst afterglow
H. Abdalla R. Adam F. Aharonian F. Ait Benkhali E. O. Anguener M. Arakawa, C. Arcaro, C. Armand +219
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…
GRB 190114C in the nuclear region of an interacting galaxy -- A detailed host analysis using ALMA, HST and VLT
A. de Ugarte Postigo, C. C. Thöne, S. Martın +28
GRB 190114C is the first GRB for which the detection of very-high energy emission up to the TeV range has been reported. It is still unclear whether environmental properties might…
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…
Investigating the multiwavelength behaviour of the flat spectrum radio quasar CTA 102 during 2013-2017
F. D'Ammando, C. M. Raiteri, M. Villata +94
We present a multiwavelength study of the flat-spectrum radio quasar CTA 102 during 2013-2017. We use radio-to-optical data obtained by the Whole Earth Blazar Telescope, 15 GHz dat…
The first six months of the Advanced LIGO's and Advanced Virgo's third observing run with GRANDMA
S. Antier, S. Agayeva, V. Aivazyan +74
We present the Global Rapid Advanced Network Devoted to the Multi-messenger Addicts (GRANDMA). The network consists of 21 telescopes with both photometric and spectroscopic facilit…
Probing binary neutron star mergers in dense environments using afterglow counterparts
Raphaël Duque, Paz Beniamini, Frédéric Daigne +1
The only binary neutron star merger gravitational wave event with detected electromagnetic counterparts recorded to date is GRB170817A. This merger occurred in a rarefied medium wi…
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…
High-energy neutrinos from fallback accretion of binary neutron star merger remnants
Valentin Decoene, Claire Guépin, Ke Fang +2
Following the coalescence of binary neutron stars, debris from the merger which remains marginally bound to the central compact remnant will fallback at late times, feeding a susta…
Polarised radiative transfer, rotation measure fluctuations and large-scale magnetic fields
Alvina Y. L. On, Jennifer Y. H. Chan, Kinwah Wu +2
Faraday rotation measure at radio wavelengths is commonly used to diagnose large-scale magnetic fields. It is argued that the length-scales on which magnetic fields vary in large-s…
Radio emission from a pulsar's magnetic pole revealed by general relativity
Gregory Desvignes, Michael Kramer, Kejia Lee +7
Binary pulsars are affected by general relativity (GR), causing the spin axes of each pulsar to precess. We present polarimetric radio observations of PSR J1906+0746 that demonstra…
