Abstract Models of thick accretion disks surrounding black holes are developed which have
a consistent time-averaged stationary behavior, and implications of these models for disk …

Vitamin A has diverse biological functions. It is transported in the blood as a complex with
retinol binding protein (RBP), but the molecular mechanism by which vitamin A is absorbed by …

Recent observational and theoretical investigations of AGN are described in reviews and
reports. Topics addressed include spectral studies in the optical, UV, and IR; polarization and …

… 1992a, b; Chakrabarti & Wiita 1992b), magnetic instabilities present on the disk or in the
putative corona above it … only 2% of the total number of zones in this work ; see Wiita et …

We consider a kinematic model for the rapid variability of AGN in both total and polarized flux
density. This picture emphasizes the changes in relativistic aberration produced when the …

We provide observational and theoretical perspectives on the currently much debated issue
of the Fanaroff-Riley (FR) morphological dichotomy of extragalactic radio sources. In this …

We simulate the variations in emission from accretion disks subjected to nonaxisymmetric
tidal perturbations generated by masses within or passing through the disk, using a two-…

… period P is related to the wavelet scale s in the Morlet function by the simple relation P =
1.03s. … a reliable estimation of p, as the 95% confidence interval for the true value of p is p ± 2[…

We report a possible detection of an ~4.6-h quasi-periodic oscillation (QPO) in the 0.3–10 keV
emission of the high-energy peaked blazar PKS 2155-304 from a 64 ks observation by the …

We present the results of our power spectral density analysis for the BL Lac object OJ 287,
utilizing the Fermi-LAT survey at high-energy γ-rays, Swift-XRT in X-rays, several ground-…
