    Multiwavelength observations of a VHE gamma-ray flare from PKS 1510-089 in 2015
    Context. PKS 1510-089 is one of only a few flat spectrum radio quasars detected in the very-high-energy (VHE, > 100 GeV) gamma-ray band. Aims: We study the...

    MUSE-AO view of the starburst-AGN connection: NGC 7130
    We present the discovery of a small kinematically decoupled core of 0.″2 (60 pc) in radius as well as an outflow jet in the archetypical AGN-starburst...

    Optical jets in blazars and radio galaxies.
    The authors have used HST/WFPC2 to observe the optical jet of the two extragalactic radio sources PKS 0521-365 (z = 0.055) and 3C 371 (z = 0.050). For PKS 0521...
