Multi-wavelength observations of a jet launch in real time from the post-changing-look Active Galaxy 1ES 1927+654
Sibasish Laha, Eileen T. Meyer, Dev R. Sadaula +34
We present results from a high cadence multi-wavelength observational campaign of the enigmatic changing look AGN 1ES 1927+654 from May 2022- April 2024, coincident with an unprece…
The spectra of IceCube Neutrino (SIN) candidate sources -- III. Optical spectroscopy and source characterization of the full sample
Simona Paiano, Renato Falomo, Aldo Treves +5
A correlation between astrophysical high-energy neutrinos and blazars has been suggested by various authors. In particular, a likely association between IceCube events and intermed…
An X-ray fading, UV brightening QSO at
Fabio Vito, Marco Mignoli, Roberto Gilli +13
Explaining the existence of SMBHs at is a persistent challenge to modern astrophysics. Multi-wavelength observations of QSOs revea…
Towards an informed quest for accretion disc winds in quasars: the intriguing case of Ton 28
Emanuele Nardini, Elisabeta Lusso, Susanna Bisogni
We report on the detection of a blueshifted Fe K absorption feature in two consecutive XMM-Newton observations of the luminous blue quasar Ton 28, at the 4 cumulative significan…
