Dynamics and geometry of the inner sub-parsec-scale jet in 3C 279 observed with the Event Horizon Telescope

Hendrik Mueller, Sebastiano D. von Fellenberg, Ai-Ling Zeng +275

The 2021 Event Horizon Telescope observations resolve the innermost jet region of the blazar 3C279 with unprecedented detail. The reconstructed images consistently reveal a compact…

The spatially resolved broad line region of IRAS 09149-6206

GRAVITY Collaboration, A. Amorim, W. Brandner +41

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

The Flux Distribution of Sgr A*

The GRAVITY Collaboration, R. Abuter, A. Amorim +54

The Galactic Center black hole Sagittarius A* is a variable NIR source that exhibits bright flux excursions called flares. The low-flux density turnover of the flux distribution is…

Detection of the Schwarzschild precession in the orbit of the star S2 near the Galactic centre massive black hole

GRAVITY Collaboration, R. Abuter, A. Amorim +53

The star S2 orbiting the compact radio source Sgr A* is a precision probe of the gravitational field around the closest massive black hole (candidate). Over the last 2.7 decades we…

An image of the dust sublimation region in the nucleus of NGC 1068

GRAVITY Collaboration, O. Pfuhl, R. Davies +40

We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very Large Telescope Inter…

The resolved size and structure of hot dust in the immediate vicinity of AGN

GRAVITY Collaboration, J. Dexter, J. Shangguan +42

We use VLTI/GRAVITY near-infrared interferometry measurements of 8 bright, Type 1 AGN to study the size and structure of hot dust heated by the central engine. We partially resolve…
