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…
KiDS-SQuaD II: Machine learning selection of bright extragalactic objects to search for new gravitationally lensed quasars
Vladislav Khramtsov, Alexey Sergeyev, Chiara Spiniello +9
The KiDS Strongly lensed QUAsar Detection project (KiDS-SQuaD) aims at finding as many previously undiscovered gravitational lensed quasars as possible in the Kilo Degree Survey. T…
Spectroscopic confirmation and modelling of two lensed quadruple quasars in the Dark Energy Survey public footprint
C. Spiniello, A. V. Sergeyev, L. Marchetti +12
Quadruply lensed quasars are extremely rare objects, but incredibly powerful cosmological tools. Only few dozen are known in the whole sky. Here we present the spectroscopic confir…
Bright lenses are easy to find: Spectroscopic confirmation of lensed quasars in the Southern Sky
C. Spiniello, A. Agnello, A. V. Sergeyev +4
Gravitationally lensed quasars are valuable, but extremely rare, probes of observational cosmology and extragalactic astrophysics. Progress in these fields has been limited just by…
