Detection of a triple nucleus in the Wolf-Rayet composite Sy 2 galaxy NGC 6764
Jochen Heidt, Francisco Pozo Nuñez, Nina Mackensen +2
We report adaptive-optics Ks-band imaging of the composite Seyfert 2 and Wolf-Rayet galaxy NGC 6764 (D = 32 Mpc), obtained with LUCI/SOUL at the Large Binocular Telescope. The nucl…
Accretion-disk sizes in two quasars with interferometrically resolved broad-line regions at and
Francisco Pozo Nuñez, Eduardo Bañados, Swayamtrupta Panda +3
We present the first direct comparison between accretion-disk (AD) and broad-line region (BLR) sizes in quasars at z > 2, combining continuum reverberation mapping with interferome…
Adaptive optics imaging of the nuclei of Seyfert 2 galaxies: An unexpectedly high incidence of nuclear stellar rings
Nina Mackensen, Jochen Heidt, Francisco Pozo Nuñez
High-resolution imaging of active galactic nuclei (AGNs) on subkiloparsec scales is essential for investigating their fueling. Observations in the near-infrared (NIR) are especiall…
Feeding frenzy in the mighty black holes: what we could learn from them?
Swayamtrupta Panda, Hygor Benati Gonçalves, Thaisa Storchi-Bergmann +14
Eddington ratio is a paramount parameter governing the accretion history and life cycles of Active Galactic Nuclei (AGNs). This short review presents a multi-faceted view of the im…
Accretion disc reverberation mapping in a high-redshift quasar
F. Pozo Nuñez, E. Bañados, S. Panda +1
Powered by supermassive black holes at their centers, quasars are among the most luminous objects in the Universe, serving as important probes of cosmic history and galaxy evolutio…
Probing the CIV continuum size luminosity relation in active galactic nuclei with photometric reverberation mapping
Swayamtrupta Panda, Francisco Pozo Nuñez, Eduardo Bañados +1
Reverberation mapping accurately determines virial black hole masses only for redshifts 0.2 by utilizing the relationship between the H broad-line region (BLR) size and th…
