Quasars as tracers of cosmic flows
J. Modzelewska, B. Czerny, M. Bilicki +6
Quasars, as the most luminous persistent sources in the Universe, have broad applications for cosmological studies. In particular, they can be employed to directly measure the expa…
The dust origin of the Broad Line Region and the model consequences for AGN unification scheme
Bozena Czerny, Justyna Modzelewska, Francesco Petrogalli +7
We propose a very simple physical mechanism responsible for the formation of the Low Ionization Line part of the Broad Line Region in Active Galactic Nuclei. It explains the scalin…
SALT long-slit spectroscopy of CTS C30.10: two-component Mg II line
J. Modzelewska, B. Czerny, K. Hryniewicz +7
Quasars can be used as a complementary tool to SN Ia to probe the distribution of dark energy in the Universe by measuring the time delay of the emission line with respect to the c…
