    Multiwavelength periodicity search in a sample of γ-ray bright blazars
    We present the results of a long-term periodicity search in a sample of γ-ray blazars within a multiwavelength context. These blazars have been selected from...

    Multiwavelength study of Cygnus A. IV. Proper motion and location of the nucleus
    Context. Cygnus A, as the nearest powerful FR II radio galaxy, plays an important role in understanding jets and their impact on the surrounding intracluster...

    Multiwavelength study of OT 081: broadband modelling of a transitional blazar
    OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source, which includes...

    Multiwavelength study of the gravitationally lensed blazar QSO B0218+357 between 2016 and 2020
    We report multiwavelength observations of the gravitationally lensed blazar QSO B0218+357 in 2016-2020. Optical, X-ray, and GeV flares were detected. 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...

    Near-infrared/optical counterparts of hotspots in radio galaxies
    We present new high spatial resolution Very Large Telescope (VLT) and Very Large Array (VLA) observations of a sample of nine low-power (P1.4GHz

    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...

    Optical spectral characterization of the TeV extreme blazar 2WHSP J073326.7+515354
    The emission from the relativistic jets in blazars usually outshines their host galaxies, challenging the determination of their distances and the...

    Optical variability of the blazar 3C 371: From minute to year timescales
    Context. The BL Lac object 3C 371 was observed by the Transiting Exoplanet Survey Satellite (TESS) for approximately a year, between July 2019 and July 2020...
