We carried out spectroscopic monitoring of 21 low-redshift Seyfert 1 galaxies using the Kast
double spectrograph on the 3 m Shane telescope at Lick Observatory from 2016 April to …

We present new near-infrared VLTI/GRAVITY interferometric spectra that spatially resolve
the broad Brγ emission line in the nucleus of the active galaxy IRAS 09149− 6206. We use …

Context. Broad emission lines are the most characteristic features in the spectra of galaxies
with an active galactic nucleus (AGN). They mostly show either single-peaked or double …

By using the GRAVITY instrument with the near-infrared (NIR) Very Large Telescope
Interferometer (VLTI), the structure of the broad (emission-) line region (BLR) in active …

We present geometric and dynamical modeling of the broad line region (BLR) for the multi-
wavelength reverberation mapping campaign focused on NGC 5548 in 2014. The data set …

The dynamics of the broad line region (BLR) in active galaxies is an open question; direct
observational constraints suggest a predominantly Keplerian motion, with possible traces of …

Fast empirical models of the broad emission line region (BLR) are a powerful tool to interpret
velocity-resolved reverberation mapping (RM) data, estimate the mass of the supermassive …

Multiwavelength variability studies of active galactic nuclei can be used to probe their inner
regions that are not directly resolvable. Dust reverberation mapping (DRM) estimates the …

In this work, we present a new, fully Bayesian analysis of the highest-resolution optical
spectrum of the supermassive black hole (SMBH) binary candidate PG 1302− 102, obtained …

The broad-line region (BLR) of active galactic nuclei (AGNs) traces gas close to the central
supermassive black hole (BH). Recent reverberation mapping (RM) and interferometric …
