VEXAS: VISTA EXtension to Auxiliary Surveys -- Data Release 2: Machine-learning based classification of sources in the Southern Hemisphere

V. Khramtsov, C. Spiniello, A. Agnello +1

We present the second public data release (DR) of the VISTA EXtension to Auxiliary Surveys (VEXAS), where we classify objects into stars, galaxies and quasars based on an ensemble…

Dynamical model of an obscuring clumpy torus in AGNs: I. Velocity and velocity dispersion maps for interpretation of ALMA observations

E. Yu. Bannikova, A. V. Sergeyev, N. A. Akerman +4

We have developed the dynamical model of a clumpy torus in an active galactic nucleus (AGN) and compared to recent ALMA observations. We present -body simulations of a torus in…

Resolving the inner accretion flow towards the central supermassive black hole in SDSS J1339+1310

V. N. Shalyapin, L. J. Goicoechea, C. W. Morgan +2

We studied the accretion disc structure in the doubly imaged lensed quasar SDSS J1339+1310 using -band light curves and UV-visible to near-IR (NIR) spectra from the first 11 obs…

Discovery of two Einstein crosses from massive post--blue nugget galaxies at z>1 in KiDS

N. R. Napolitano, R. Li, C. Spiniello +18

We report the discovery of two Einstein Crosses (ECs) in the footprint of the Kilo-Degree Survey (KiDS): KIDS J232940-340922 and KIDS J122456+005048. Using integral field spectrosc…

Liverpool-Maidanak monitoring of the Einstein Cross in 20062019. I. Light curves in the optical bands and microlensing signatures

L. J. Goicoechea, B. P. Artamonov, V. N. Shalyapin +8

Quasar microlensing offers a unique opportunity to resolve tiny sources in distant active galactic nuclei and study compact object populations in lensing galaxies. We therefore sea…

Interpretation of ALMA velocity map for the obscuring torus in NGC1068

E. Yu. Bannikova, N. A. Akerman, A. V. Sergeyev

Recent ALMA observations have resolved the obscuring torus in the nearest Sy2 galaxy, NGC1068, in the millimeter band. These observations have confirmed the presence of a geometric…
