AT 2021hdr: A candidate tidal disruption of a gas cloud by a binary super massive black hole system
L. Hernández-García, A. M. Muñoz-Arancibia, P. Lira +25
With a growing number of facilities able to monitor the entire sky and produce light curves with a cadence of days, in recent years there has been an increased rate of detection of…
NOEMA spatially resolved view of the multi-phase outflow in IRAS17020+4544: a shocked wind in action?
Anna Lia Longinotti, Quentin Salomé, Chiara Feruglio +10
The Narrow Line Seyfert 1 Galaxy IRAS17020+4544 is one of the few AGN where a galaxy-scale energy-conserving outflow was revealed. This paper reports on NOEMA observations addresse…
Evidence of galaxy interaction in the Narrow-line Seyfert 1 galaxy IRAS17020+4544 seen by NOEMA
Q. Salomé, A. L. Longinotti, Y. Krongold +9
The narrow-line Seyfert 1 galaxy IRAS17020+4544 is one of the few sources where both an X-ray ultra-fast outflow and a molecular outflow were observed to be consistent with energy…
Baldwin Effect and Additional BLR Component in AGN with Superluminal Jets
V. M. Patiño-Ávarez, J. Torrealba, V. Chavushyan +4
We study the Baldwin Effect (BE) in 96 core-jet blazars with optical and ultraviolet spectroscopic data from a radio-loud AGN sample obtained from the MOJAVE 2 cm survey. A statist…
Long-term optical spectral monitoring of a changing-look AGN NGC 3516 I: Continuum and broad-line flux variability
A. I. Shapovalova, L. C. Popovic, V. L. Afanasiev +11
Here we present the long-term optical spectral monitoring of a changing-look active galactic nuclei (AGN) NGC 3516 that covers 22 years (from 1996 to 2018). We explore a variabilit…
Early Science with the Large Millimeter Telescope: an energy-driven wind revealed by massive molecular and fast X-ray outflows in the Seyfert Galaxy IRAS 17020+4544
A. L. Longinotti, O. Vega, Y. Krongold +23
We report on the coexistence of powerful gas outflows observed in millimeter and X-ray data of the Radio-Loud Narrow Line Seyfert 1 Galaxy IRAS 17020+4544. Thanks to the large coll…
Detection of helicoidal motion in the optical jet of PKS 0521-365
E. F. Jiménez-Andrade, V. Chavushyan, J. León-Tavares +5
The jet activity of Active Galactic Nuclei (AGN), and its interaction with the interstellar medium (ISM), may play a pivotal role in the processes which regulate the growth and sta…
Long-term optical spectral monitoring of NGC 7469
Alla I. Shapovalova, L. C. Popović, V. H. Chavushyan +11
We present the results of the long-term (20-year period, from 1996 to 2015) optical spectral monitoring of the Seyfert 1 galaxy NGC 7469. The variation in the light-curves of the b…
First long-term optical spectro-photometric monitoring of a binary black hole candidate E1821+643: I. Variability of spectral lines and continuum
A. I. Shapovalova, L. C. Popovic, V. H. Chavushyan +9
We report the results of the first long-term (1990-2014) optical spectro-photometric monitoring of a binary black hole candidate QSO E1821+643, a low-redshift high-luminosity radio…
Spectral optical monitoring of the double peaked emission line AGN Arp 102B: II. Variability of the broad line properties
L. C. Popovic, A. I. Shapovalova, D. Ilic +9
We investigate a long-term (26 years, from 1987 to 2013) variability in the broad spectral line properties of the radio galaxy Arp 102B, an active galaxy with broad double-peaked e…
