The South Pole Telescope AGN Monitoring Campaign: First Release of SPTpol Bright AGN Light Curves
J. C. Hood, P. A. R. Ade, A. J. Anderson +66
The South Pole Telescope (SPT) collaboration has recently embarked upon a campaign to monitor the brightness of a sample of active galactic nuclei (AGN), both in real time and in a…
First detection of VHE gamma-ray signal from the FSRQ TON 0599
MAGIC Collaboration, K. Abe, S. Abe +245
TON\,0599 (z=0.7247) belongs to the few flat spectrum radio quasars (FSRQs) detected in the very high energy (VHE, \,GeV) gamma-ray band. Its redshift makes it currently o…
NOCTURNE. III. Unidentified variable emission in the nuclear regions of PKS 2153-69
Miguel Coloma Puga, Marco Berton, Pierpaolo Condò +4
Historically, the study of the central regions of Type 1 AGN has been limited by the combination of the host galaxy spectrum with strong emission from the accretion disk and NLR/BL…
Investigating the origin of radio emission in candidate super-Eddington accreting black holes
Marie-Lou Gendron-Marsolais, Paola Marziani, Marco Berton +8
Recent works show that the radio power of quasars accreting at very high rates can reach surprisingly high values. These studies suggest that this radio emission might originate fr…
NOCTURNE. I. The radio spectrum of narrow-line Seyfert 1 galaxies
M. Berton, E. Järvelä, S. Chen +8
The origin of the radio emission in active galactic nuclei (AGN) is still debated. Multiple physical mechanisms can contribute to the spectrum at these frequencies, including relat…
Revised optical classification of a sample of gamma-ray emitting AGN with GTC and VLT
B. Dalla Barba, L. Foschini, M. Berton +10
We report the results of the optical follow-up of a sample of -ray-emitting active galactic nuclei (AGN). New high-quality optical spectra were obtained using Gran Telescopio C…
