Journal ArticleDOI
The origin of the broad line region in active galactic nuclei
TL;DR: In this paper, the authors studied the properties of the accretion disk underlying the broad line region and found that the effective temperature at the disk radius corresponding to the location of the broad-line region, as inferred from the Hβ line, is universal in all monitored sources and equal to 1000 K.

The origin of the Broad Line Region in Active Galactic Nuclei
TL;DR: In this paper, the authors studied the properties of the accretion disk underlying the broad line region and found that the effective temperature at the disk radius corresponding to the location of the broad emission lines, as inferred from the H$\beta$ line, is universal in all monitored sources and equal to 1000 K.

TL;DR: In the Sassenfjorden area of Spitsbergen, Svalbard, 15 carbonate bodies have been found in the siltstones and mudstones of the uppermost Slottsmoya Member, in the Upper Jurassic to lowermost Cretaceous Agardhfjellet Formation as discussed by the authors.
Journal ArticleDOI
Modeling of the Quasar Main Sequence in the Optical Plane
Swayamtrupta Panda,Bozena Czerny,T. P. Adhikari,Krzysztof Hryniewicz,Conor Wildy,Joanna Kuraszkiewicz,Marzena Śniegowska +6 more
TL;DR: In this paper, a physically motivated model was proposed to explain the distribution of quasars in the optical plane, where a hard X-ray power law uniquely tight to the disk at the basis of observational scaling, and the Broad Line Region distance was determined also from observational scaling.
Journal ArticleDOI
Constraints on the black hole spin in the quasar SDSS J094533.99+100950.1
TL;DR: In this paper, a numerical code for computing disc properties, including a radius-dependent hardening factor, and apply the ray-tracing method to incorporate all general relativity effects in light propagation.
