Scrutinizing the 2020 multiwavelength outburst of PKS 0903-57 through observations with H.E.S.S

A. Acharyya, F. Aharonian, F. Ait Benkhali +138

The blazar PKS 0903-57 has recently been classified as a flat spectrum radio quasar at a redshift of . In March and April 2020, Fermi-LAT and AGILE reported tremendous ac…

Laboratory observation of collective beam-plasma instabilities in a relativistic pair jet

J W D Halliday, C D Arrowsmith, A M Goillot +37

We report on a measurement of collective behavior in a relativistic electron-positron pair plasma produced in the laboratory. Using the Fireball platform at CERN's HiRadMat facilit…

H.E.S.S. detection of the PSR J0855-4644 nebula

F. Aharonian, H. Ashkar, M. Backes +131

HESS J0852-463 is a TeV γ-ray source located in the Galactic plane. The region consists of a supernova remnant (SNR, RX J0852.0-4622) with a shell-like morphology, commonly referre…

Dynamic shocks powered by a wide, relativistic, super-Eddington outflow launched by an accreting neutron star in the mid-20th century

F. J. Cowie, R. P. Fender, I. Heywood +11

Accreting systems can launch powerful outflows which interact with the surrounding medium. We combine new radio observations of the accreting neutron star X-ray binary (XRB) Circin…

Constraining the nature of the most extreme Galactic particle accelerator. H.E.S.S. observations of the microquasar V4641 Sgr

A. Acharyya, F. Aharonian, H. Ashkar +131

Microquasars have emerged as promising candidates to explain the cosmic-ray flux at petaelectronvolt energies. LHAASO observations revealed V4641~Sgr as the most extreme example so…

Deciphering the gamma-ray emission in the Cygnus region

L. Haerer, T. Vieu, F. Schulze +2

The Cygnus region is a vast star-forming complex harbouring a population of powerful objects, including massive star clusters and associations, Wolf-Rayet stars, pulsars, and super…
