AGN candidates in the VVV near-IR galaxy catalogue

Laura D. Baravalle, Eduardo O. Schmidt, M. Victoria Alonso +7

The goal of this work is to search for Active Galactic Nuclei (AGN) in the Galactic disc at very low latitudes with |b| 2. For this, we studied the five sources from th…

BAT AGN Spectroscopic Survey -- XIX: Type 1 versus Type 2 AGN dichotomy from the point of view of ionized outflows

A. F. Rojas, E. Sani, I. Gavignaud +18

We present a detailed study of ionized outflows in a large sample of ~650 hard X-ray detected AGN. Using optical spectroscopy from the BAT AGN Spectroscopic Survey (BASS) we are ab…

VVV-WIT-04: an extragalactic variable source caught by the VVV Survey

Roberto K. Saito, Dante Minniti, Valentin D. Ivanov +8

We report the discovery of VVV-WIT-04, a near-infrared variable source towards the Galactic disk located ~0.2 arcsec apart from the position of the radio source PMN J1515-5559. The…

Restarting activity in the nucleus of PBC J2333.9-2343: an extreme case of jet realignment

L. Hernández-García, F. Panessa, M. Giroletti +8

PBC J2333.9-2343 is a giant radio galaxy which shows different characteristics at different wavebands that are difficult to explain within the actual generic schemes of unification…

BAT AGN Spectroscopic Survey - IV: Near-Infrared Coronal Lines, Hidden Broad Lines, and Correlation with Hard X-ray Emission

Isabella Lamperti, Michael Koss, Benny Trakhtenbrot +13

We provide a comprehensive census of the near-Infrared (NIR, 0.8-2.4 m) spectroscopic properties of 102 nearby (z < 0.075) active galactic nuclei (AGN), selected in the hard X-r…

BAT AGN Spectroscopic Survey-III. An observed link between AGN Eddington ratio and narrow emission line ratios

Kyuseok Oh, Kevin Schawinski, Michael Koss +14

We investigate the observed relationship between black hole mass (), bolometric luminosity (), and Eddington ratio () with optical emission li…
