Strong FeII emission in NLS1s: An unsolved mystery
Swayamtrupta Panda, Katarzyna Małek, Marzena Śniegowska +1
The work initially started as a test to retrace the Shen & Ho (2014) Quasar Main Sequence diagram where they claimed that the parameter RFeII, which defines the Eigenvector 1 (EV1)…
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…
Quasar main sequence in the UV plane
Marzena Śniegowska, Szymon Kozłowski, Bożena Czerny +2
Active galaxies form a clear pattern in the optical plane showing the correlation between the Full Width Half Maximum (FWHM) of the H line and the ratio of the Equivalent Width…
Narrow-line Seyfert 1 galaxies in the context of the Quasar Main Sequence
Bozena Czerny, Swayamtrupta Panda, Marzena Sniegowska +4
Narrow-line Seyfert 1 galaxies are defined on the basis of their line widths, and they are generally considered to be high Eddington ratio sources. But in the context of the Quasar…
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…
Using vo tools to iNvestIgate Quasar Spectra (UNIQS)
Swayamtrupta Panda, Katarzyna Małek, Marzena Śniegowska +1
The work initially started as a test to retrace the Shen & Ho (2014) Quasar Main Sequence diagram where they (and references therein) claimed that the parameter RFeII, which define…
