ULISSE: A Tool for One-shot Sky Exploration and its Application to Active Galactic Nuclei Detection
Lars Doorenbos, Olena Torbaniuk, Stefano Cavuoti +5
Modern sky surveys are producing ever larger amounts of observational data, which makes the application of classical approaches for the classification and analysis of objects chall…
The connection between star formation and supermassive Black Hole activity in the local Universe
Olena Torbaniuk, Maurizio Paolillo, Francisco Carrera +4
We present a study of the active galactic nucleus (AGN) activity in the local Universe (z < 0.33) and its correlation with the host galaxy properties, derived from a Sloan Digital…
Dependence between some spectral and physical characteristics of quasars
O. Torbaniuk, G. Ivashchenko
Using 192 composite spectra stacked from subsamples of individual SDSS DR7 quasar spectra binned in spectral index, , and logarithm of monochromatic luminosity at 1450 Å, $\lo…
Some spectral properties of the quasar ultraviolet bump
O. Torbaniuk, G. Ivashchenko, O. Sergijenko
In the present work the part of the quasar UV-optical bump within the wavelength range 1210-1450Å was studied with the help of composite spectra compiled from the samples of SDSS D…
Composite spectra of quasars with different UV spectral index
G. Ivashchenko, O. Sergijenko, O. Torbaniuk
The composite spectra of quasars are widely used as templates for redshift determination, as well as for measurements of the mean transmission in Lyα-forest studies, and for invest…
