Broad He I 1.08 μm absorption from the obscurer in the active galaxy NGC 5548
Conor Wildy, Hermine Landt, Martin J. Ward +2
The nucleus of the active galaxy NGC 5548 was the target of two intensive spectroscopic monitoring campaigns at X-ray, ultraviolet (UV), and optical frequencies in 2013/14. These c…
Quasar Main Sequence: a line or a plane?
Conor Wildy, Bozena Czerny, Swayamtrupta Panda
A quasar main sequence is widely believed to reveal itself through objects represented in a plane spanned by two parameters: the full-width at half-maximum (FWHM) of H, and the…
Stellar populations in hosts of giant radio galaxies and their neighbouring galaxies
Agnieszka Kuźmicz, Bożena Czerny, Conor Wildy
Context: Giant radio galaxies (with projected linear size of radio structure larger than 0.7 Mpc) are very rare and unusual objects. Only 5% of extended radio sources reach s…
Interpretation of Departure from the Broad Line Region Scaling in Active Galactic Nuclei
Bozena Czerny, Jian-Min Wang, Pu Du +7
Most results of the reverberation monitoring of active galaxies showed a universal scaling of the time delay of the Hbeta emission region with the monochromatic flux at 5100 A, wit…
Modelling of the quasar main sequence in the optical plane
Swayamtrupta Panda, Bożena Czerny, Tek P. Adhikari +4
The concept of the quasar main sequence is very attractive since it stresses correlations between various parameters and implies the underlying simplicity. In the optical plane def…
Mg II line properties in lobe-dominated quasars
Conor Wildy, Bozena Czerny, Agnieszka Kuźmicz
We investigate the relationships between Mg ii λ2798 emission line properties, as well as between these properties and inclination angle and Fe ii strength, in a lobe-dominated qua…
What drives the Quasar Main Sequence?
Swayamtrupta Panda, Bożena Czerny, Conor Wildy +1
Eigenvector 1 (EV1) was found to be the dominant component behind the significant correlations for the measured parameters in quasar spectra (Boroson & Green, 1992). The parameter…
Testing the physical driver of Eigenvector 1 in Quasar Main Sequence
Swayamtrupta Panda, Bożena Czerny, Conor Wildy +1
Quasars are among the most luminous sources characterized by their broad band spectra ranging from radio through optical to X-ray band, with numerous emission and absorption featur…
The relationship between Mg II broad emission and quasar inclination angle
Conor Wildy, Bozena Czerny
Several observed spectral properties of quasars are believed to be influenced by quasar orientation. In this investigation we examine the effect of orientation on the Mg II line lo…
The physical driver of the optical Eigenvector 1 in Quasar Main Sequence
Swayamtrupta Panda, Bozena Czerny, Conor Wildy
Quasars are complex sources, characterized by broad band spectra from radio through optical to X-ray band, with numerous emission and absorption features. However, Boroson & Green…
Self-consistent dynamical model of the Broad Line Region
Bozena Czerny, Yan-Rong Li, Justyna Sredzinska +4
We develope a self-consistent description of the Broad Line Region based on the concept of the failed wind powered by the radiation pressure acting on dusty accretion disk atmosphe…
Failed radiatively Accelerated Dusty Outflow model of the Broad Line Region in Active Galactic Nuclei. I. Analytical solution
B. Czerny, Yan-Rong Li, K. Hryniewicz +6
The physical origin of the Broad Line Region in Active Galactic Nuclei is still unclear despite many years of observational studies. The reason is that the region is unresolved and…
The properties of active galaxies at the extreme of eigenvector 1
M. Sniegowska, B. Czerny, B. You +4
Eigenvector 1 (EV1) is the formal parameter which allows the introduction of some order in the properties of the unobscured type 1 active galaxies. We aim to understand the nature…
Physical properties and the variability mechanism of the He I outflow in NGC 4151
Conor Wildy, Hermine Landt, Michael R. Goad +2
We report on variable helium absorption lines in NGC 4151 observed across six epochs of quasi-simultaneous near-infrared and optical data. These observations cover the transitions…
SDSS J1138+3517: A quasar showing remarkably variable broad absorption lines
Conor Wildy, Michael R. Goad, James T. Allen
We report on the highly variable SiIV and CIV broad absorption lines in SDSS J113831.4+351725.2 across four observational epochs. Using the SiIV doublet components, we find that th…
Quasar broad absorption line variability measurements using reconstructions of un-absorbed spectra
Conor Wildy, Michael R. Goad, James T. Allen
We present a two-epoch Sloan Digital Sky Survey and Gemini/GMOS+William Herschel Telescope/ISIS variability study of 50 broad absorption line quasars of redshift range 1.9 < z < 4.…
