VLTI/GRAVITY Interferometric Measurements of Innermost Dust Structure Sizes around AGNs

GRAVITY Collaboration, A. Amorim, G. Bourdarot +41

We present new VLTI/GRAVITY near-infrared interferometric measurements of the angular size of the innermost hot dust continuum for 14 type 1 AGNs. The angular sizes are resolved on…

GATOS: missing molecular gas in the outflow of NGC5728 revealed by JWST

R. Davies, T. Shimizu, M. Pereira-Santaella +49

The ionisation cones of NGC5728 have a deficit of molecular gas based on millimetre observations of CO(2-1) emission. Although photoionisation from the active nucleus may lead to s…

A dynamical measure of the black hole mass in a quasar 11 billion years ago

R. Abuter, F. Allouche, A. Amorim +124

Tight relationships exist in the local universe between the central stellar properties of galaxies and the mass of their supermassive black hole. These suggest galaxies and black h…

Broad-line region geometry from multiple emission lines in a single-epoch spectrum

L. Kuhn, J. Shangguan, R. Davies +17

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 spe…

The size-luminosity relation of local active galactic nuclei from interferometric observations of the broad-line region

GRAVITY Collaboration, A. Amorim, G. Bourdarot +42

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 galactic…
