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)…
Accretion in Active Galactic Nuclei
Bozena Czerny, Mohammad-Hassan Naddaf
We review the current status of the understanding how the accretion onto the central black hole proceeds in Active Galaxies. Standard accretion disk is a key element in all relativ…
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…
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…
