Shocks, Winds, and a Torus: The Large Binocular Telescope Interferometer (LBTI) Resolves the Active Nucleus of NGC 4151

Jacob W. Isbell, Steve Ertel, Makoto Kishimoto +12

We present mid-infrared (MIR) observations of the Seyfert 1 galaxy NGC 4151 using the Large Binocular Telescope Interferometer (LBTI). We took open-loop Fizeau images with 66-104 m…

Broad line region echo from highly accreting intermediate-mass black hole candidate SDSS J144850.08+160803.1. The first probe of intra-night variability and reverberation mapping

Mariia Demianenko, Anton Afanasiev, Evgenii Rubtsov +8

Elusive intermediate-mass black holes (IMBHs) can be used as ``time-squeezing'' machines, enabling studies of AGN geometry via reverberation mapping on much shorter timescales than…

Modal Identification of Mirror Vibrations at the VLT using Accelerometer Data

Pascal Jaufmann, Aaron Buck, Jörg-Uwe Pott +1

Recent advances in ground-based astronomy have made it possible to create optical telescopes with primary mirrors up to 40 m in size. With growing mirror diameter, the suppression…

Simulation of Wavefront-based Disturbance Observers for Large Telescopes

Pascal Jaufmann, Aaron Buck, Marco Zaiser +2

The performance of future observatories such as the Extremely Large Telescope is mainly limited by atmospheric turbulence and structural vibrations of the optical assembly. To furt…

Direct imaging of AGN outflows and their origin with the 23 m Large Binocular Telescope

Jacob W. Isbell, Steve Ertel, Jörg-Uwe Pott +17

Active galactic nuclei (AGNs) are a key component of galaxy evolution due to feedback on the host from its supermassive black hole. The morphology of warm, in- and outflowing dusty…
