Mass loss rate of accretion disk in FRADO
Mohammad-Hassan Naddaf, Bozena Czerny
We have developed the 2.5D version of the basic physically motivated 1D model of Czerny & Hryniewicz (2011), i.e. Failed Radiatively Accelerated Dusty Outflow (FRADO) model. This m…
Do reverberation-measured H quasars provide a useful test of cosmology?
Narayan Khadka, Mary Loli Martínez-Aldama, Michal Zajaček +2
We use 118 H quasar (QSO) observations in the redshift range to simultaneously constrain cosmological model parameters and QSO 2-parameter radius-lumin…
Radiation pressure on dust explains the Low Ionized Broad Emission Lines in Active Galactic Nuclei
Mohammad-Hassan Naddaf, Bozena Czerny
Broad emission lines are the most characteristic features in the spectra of active galaxies. They mostly show either a single-peaked or double-peaked profiles; and originate from a…
Modeling changing-look (CL) AGN phenomenon in 1D using accretion disk instabilities
Marzena Sniegowska, Mikolaj Grzedzielski, Bozena Czerny +1
Apart from regular, low-level stochastic variability, some AGN occasionally show exceptionally large changes in the luminosity, spectral shape, and/or X-ray absorption. The most no…
Linear Spectropolarimetric Analysis of Fairall 9 with VLT/FORS2
Bo-Wei Jiang, Paola Marziani, Đorđe Savić +10
The quasar Main Sequence (MS) appears to be an incredibly powerful tool to organize the diversity in large samples of type-1 quasars but the most important physical parameters gove…
Standardizing reverberation-measured Mg II time-lag quasars, by using the radius-luminosity relation, and constraining cosmological model parameters
Narayan Khadka, Zhefu Yu, Michal Zajaček +3
We use 78 reverberation-measured Mg II time-lag quasars (QSOs) in the redshift range to constrain cosmological parameters in six different cosmological mo…
