Towards equation of state of dark energy from quasar monitoring: Reverberation strategy
TL;DR: In this article, the authors proposed a method based on determination of the size of the Broad Line Region from the emission line delay, determination of absolute monochromatic luminosity either from the observed statistical relation or from a model of the formation of the broad line region, and determination of observed monochrome flux from photometry.

Bozena Czerny,K. Hryniewicz,Ishita Maity,A. Schwarzenberg-Czerny,Piotr T. Życki,Maciej Bilicki +5 more
TL;DR: In this paper, the authors used the broad line region (BLR) from the emission line delay, the determination of the absolute monochromatic luminosity either from the observed statistical relation or from a model of the formation of the BLR, and the observed monochrome flux from photometry.
Journal ArticleDOI
SDSS J094533.99+100950.1 – the remarkable weak emission line quasar
TL;DR: Weak emission line quasars are a rare and puzzling group of objects as discussed by the authors, and their line properties are not consistent with the trends expected at high accretion rates, which may indicate that the quasar active phase consists of several sub-phases, each starting with a fresh build-up of the Broad Line Region.
Journal ArticleDOI
The dust origin of the Broad Line Region and the model consequences for AGN unification scheme
Bozena Czerny,Justyna Modzelewska,Francesco Petrogalli,Wojtek Pych,T. P. Adhikari,Piotr T. Życki,K. Hryniewicz,Magdalena Krupa,Agnieszka Świe¸toń,Marek Nikolajuk +9 more
TL;DR: In this article, a simple physical mechanism was proposed for the formation of the Low Ionization Line part of the Broad Line Region in Active Galactic Nuclei, where the local effective temperature of a non-illuminated accretion disk drops below 1000 K and allows for dust formation.
Journal ArticleDOI
The mass of the black hole in RE J1034+396
Bozena Czerny,Bei You,Agnieszka Kurcz,J. Sredzinska,K. Hryniewicz,Marek Nikolajuk,M. Krupa,Jian-Min Wang,C. Hu +8 more
TL;DR: In this article, the authors measured the black hole mass in a very special object, RE J1034+396, one of the two AGNs with QPO oscillations detected in X-rays, and a single bright AGN with optical band totally dominated by starlight.
