Optical singly-ionized iron emission in radio-quiet and relativistically jetted active galactic nuclei
Paola Marziani, Marco Berton, Swayamtrupta Panda +1
The issue of the difference between optical and UV properties of radio-quiet and radio-loud (relativistically "jetted") active galactic nuclei (AGN) is a long standing one, related…
Metallicity evolution in quasars
Swayamtrupta Panda, Ewa Julia Skorek
Broad-band spectra of active galaxies contain a wide range of information that help reveal the nature and activity of the central continuum source and their immediate surroundings.…
A novel black hole mass scaling using coronal lines in active galaxies
Swayamtrupta Panda, Alberto Rodríguez Ardila
Using bonafide black hole (BH) mass estimates from reverberation mapping and the line ratio [Si VI]1.963m/Br as tracer of the Active Galactic Nuclei (AGN) ionizin…
Optical Fe II and near-infrared Ca II emission in active galaxies
Swayamtrupta Panda
The CaFe Project involves the study of the properties of the low ionization emission lines (LILs) pertaining to the broad-line region (BLR) in active galaxies. These emission lines…
Taming the derivative: diagnostics of the continuum and H emission in a prototypical Population B active galaxy
Swayamtrupta Panda, Edi Bon, Paola Marziani +1
We report preliminary results on the analysis of the continuum and H light curves of the type-1 active galactic nucleus (AGN) NGC 5548. We notice a clear signature of shallowing…
Revisiting the spectral energy distribution of I Zw 1 under the CaFe Project
Swayamtrupta Panda, Denimara Dias dos Santos
The CaFe Project involves the study of the properties of the low ionization emission lines (LILs) pertaining to the broad-line region (BLR) in active galaxies. These emission lines…
