PublicationOptical 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...

PublicationOptical 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...
