The Blazar Sequence and Its Physical Understanding
Galaxies, 2022 Introduced in 1998 to attempt a first unified view of the broad-band emission properties of blazars, the blazar sequence has been extensively used in the past 25 years to guide observations as well as the physical interpretation of the overall emission ...Elisa Prandini, Gabriele Ghisellinidoaj +1 more sourceBasic properties of Fermi blazars and the ‘blazar sequence’ [PDF]

Astronomische Nachrichten, Volume 344, Issue 4, May 2023., 2023 Abstract
We are carrying out the densest and longest multiyear, multiwavelength monitoring project of OJ 287 ever done. The project MOMO (Multiwavelength Observations and Modeling of OJ 287) covers wavelengths from the radio to the high‐energy regime. A few selected observations are simultaneous with those of the Event Horizon Telescope (EHT).S. Komossa, A. Kraus, D. Grupe, M.L. Parker, A. Gonzalez, L.C. Gallo, M.A. Gurwell, S. Laine, S. Yao, S.

Journal of Computer Assisted Learning, Volume 39, Issue 2, Page 578-590, April 2023., 2023 Abstract Background
The growth of teaching practices conducted to promote cognitive activation and active participation in the classroom in recent years has become the epicentre of an active debate regarding their effectiveness. Objectives
This study is aimed to shed some light on this topic by empirically analysing the causes and consequences of more ...Adriano Villar‐Aldonzawiley +1 more sourceBlazar Optical Variability in the Palomar-QUEST Survey [PDF]

flux [PDF]
, 2016 The recent discovery of a diffuse cosmic neutrino flux extending up to PeV
energies raises the question of which astrophysical sources generate this
signal. One class of extragalactic sources which may produce such high-energy
neutrinos are blazars.Aartsen, M. G., Abraham, K., Ackermann, M., Adams, J., Aguilar, J.

Monthly Notices of the Royal Astronomical Society, 2004 We discuss the properties of the sources in the CLASS Blazar survey which aims at the selection of low radio power (P(5GHz)<10^25 W Hz^-1) blazars. We use VLA data from available catalogues and from our own observations to constrain the radio core-dominance of the sample which, together with the flat radio spectral index, is a signature of the ...Caccianiga, A., Marcha, M.

, 2019 High redshift blazars are an important class of Active Galactic Nuclei (AGN)
that can provide an independent estimate of the supermassive black-hole mass
function in high redshift radio-loud AGN without the bias due to absorption
along the line-of-sight. Antón, Sonia, Ballo, Lucia, Belladitta, Silvia, Caccianiga, Alessandro, Cicone, Claudia, Dallacasa, Daniele, Della Ceca, Roberto, Gargiulo, Adriana, Ighina, Luca, Marchã, Maria J., Moretti, Alberto, Severgnini, Paola +11 morecore +2 more sources
