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…

Jet propagation velocity and environment density of giant radio sources with steep radio spectrum

Alla Miroshnichenko

Before we have determined that giant radio structure is typical for steep-spectrum sources detected with Ukrainian T-shaped Radio Telescope of model 2 (UTR-2). To estimate the jet…

KiDS0239-3211: A new gravitational quadruple lens candidate

A. Sergeyev, C. Spiniello, V. Khramtsov +5

We report the discovery of a candidate to quadrupole gravitationally lensed system KiDS0239-3211 based on the public data release 3 of the KiDS survey and machine learning techniqu…

Spectroscopic follow-up of double quasar candidates

V. N. Shalyapin, A. V. Sergeyev, L. J. Goicoechea +1

We report the results of an optical spectroscopic follow-up of four double quasar candidates in the Sloan Digital Sky Survey (SDSS) database. SDSS J1617+3827 is most likely a lense…

KiDS-SQuaD: The KiDS Strongly lensed Quasar Detection project

C. Spiniello, A. Agnello, N. R. Napolitano +11

New methods have been recently developed to search for strong gravitational lenses, in particular lensed quasars, in wide-field imaging surveys. Here, we compare the performance of…

The structure and stability of orbits in Hoag-like ring systems

Elena Yu. Bannikova

Ring galaxies are amazing objects exemplified by the famous case of the Hoag's Object. Here the mass of the central galaxy may be comparable to the mass of the ring, making it a di…

Dynamics and formation of obscuring tori in AGNs

Elena Yu. Bannikova, Alexey V. Sergeyev

We considered the evolution of a self-gravitating clumpy torus in the gravitational field of the central mass of an active galactic nucleus (AGN) in the framework of the N-body pro…
