Long Gamma-Ray Bursts (GRBs) are the most dramatic examples of massive stellar deaths, usually associated with supernovae ( Woosley et al. 2006). They release...
H1517+656 is an unusual source, even for a BL Lac object. It is one of the most luminous BL Lac objects known, with extreme emission properties at radio...
Hubble Space Telescope Observations of the Optical Jets of PKS 0521-365, 3C 371, and PKS 2201+044
Hubble Space Telescope (HST) observations have led to the discovery of the optical counterpart of the radio jet of PKS 2201+044 and to a detailed analysis of...
In-situ particle acceleration in extragalactic radio hot spots: observations meet expectations
We discuss, in terms of particle acceleration, the results from optical VLT observations of hot spots associated with radio galaxies. On the basis of...
Insights into the emission of the blazar 1ES 1011+496 through unprecedented broadband observations during 2011 and 2012
Context. 1ES 1011+496 (z = 0.212) was discovered in very high-energy (VHE, E> 100 GeV) γ rays with MAGIC in 2007. The absence of simultaneous data at lower...
Interactions between large-scale radio structures and gas in a sample of optically selected type 2 quasars
Context. The role of radio mode feedback in non radio-loud quasars needs to be explored in depth to determine its true importance. Its effects can be identified...
Investigating the Blazar TXS 0506+056 through Sharp Multiwavelength Eyes During 2017-2019
The blazar TXS 0506+056 got into the spotlight of the astrophysical community in 2017 September, when a high-energy neutrino detected by IceCube (IceCube...
Investigating the multiwavelength behaviour of the flat spectrum radio quasar CTA 102 during 2013-2017
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...
Jet-induced molecular gas excitation and turbulence in the Teacup
In order to investigate the impact of radio jets on the interstellar medium (ISM) of galaxies hosting active galactic nuclei (AGN), we present subarcsecond...
