Optical and cm follow-ups of the Changing-Look event in Mkn 590
Biswaraj Palit, Abhijeet Borkar, Agata Różańska +5
The Changing-Look active galactic nucleus Mkn 590 is currently in a rejuvenated state, exhibiting a contemporaneous flux rise across X-rays, UV, optical and cm wavelengths. In this…
High metal content of highly accreting quasars
Marzena Śniegowska, Paola Marziani, Bożena Czerny +4
We present an analysis of UV spectra of 13 quasars believed to belong to extreme Population A (xA) quasars, aimed at the estimation of the chemical abundances of the broad line emi…
The CaFe Project: Optical Fe II and Near-Infrared Ca II triplet emission in active galaxies: (I) Photoionization modelling
Swayamtrupta Panda, Mary Loli Martínez-Aldama, Murilo Marinello +3
Optical Fe II emission is a strong feature in quasar spectra originating in the broad-line region (BLR). The difficulty in understanding the complex Fe II pseudo-continuum has led…
Generating AGN spectra for LSST: First steps
Swayamtrupta Panda, Bożena Czerny
In the near future, the arrival of new surveys promises a significant increment in the number of quasars (QSO) at large redshift ranges. This will help to constrain the dark energy…
Explaining the Broad-line Region through photoionisation modelling
Swayamtrupta Panda
Broad-line regions (BLR) are one of the main components that constitute the phenomenological picture of active galaxies near the vicinity of the accreting supermassive black holes.…
Current and future applications of Reverberation-mapped quasars in Cosmology
Swayamtrupta Panda, Mary Loli Martínez-Aldama, Michal Zajaček
Reverberation mapping technique is an important milestone in AGN demographics, kinematics and the structure of the Broad Line Region (BLR) based on the time-delay response between…
