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…
A simulation-based quality-control framework for the broad-line region radius-luminosity relation
Juri Wladimir Seib, Francisco Pozo Nuñez, Sarah Elena Ivana Bosman
The broad-line region (BLR) radius-luminosity (R-L) relation underpins single-epoch black hole mass estimates in active galactic nuclei (AGN). The published Hβsample is heterogeneo…
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…
HALO II: Constraining Hubble constant through continuum delay fitting of Fairall 9
Amit Kumar Mandal, Francisco Pozo Nuñez, Vikram Kumar Jaiswal +28
The Hubble tension remains one of the most significant unresolved problems in modern cosmology. A key question is whether it may arise from underestimated systematic uncertainties…
Extraction method for response functions from X-ray light curves of AGN by optimization algorithm
Sanhanat Deesamutara, Tirawut Worrakitpoonpon, Poemwai Chainakun +4
We introduce a numerical optimization method to extract the X-ray reverberation response functions from the multi-band light curves of the active galactic nuclei. This approach doe…
