The GRAVITY young stellar object survey XIII. Tracing the time-variable asymmetric disk structure in the inner AU of the Herbig star HD98922

GRAVITY Collaboration, V. Ganci, L. Labadie +52

Temporal variability in the photometric and spectroscopic properties of protoplanetary disks is common in YSO. However, evidence pointing toward changes in their morphology over sh…

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…

Single-mode waveguides for GRAVITY II. Single-mode fibers and Fiber Control Unit

G. Perrin, L. Jocou, K. Perraut +22

The 2nd generation VLTI instrument GRAVITY is a two-field infrared interferometer operating in the K band between 1.97 and 2.43 m with either the four 8 m or the four 1.8 m tele…

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…

The GRAVITY young stellar object survey: XI. Imaging the hot gas emission around the Herbig Ae star HD 58647

Y. -I. Bouarour, R. Garcia Lopez, J. Sanchez-Bermudez +45

We aim to investigate the origin of the HI Br emission in young stars by using GRAVITY to image the innermost region of circumstellar disks, where important physical processes s…

VLTI/GRAVITY Provides Evidence the Young, Substellar Companion HD 136164 Ab formed like a "Failed Star"

William O. Balmer, L. Pueyo, S. Lacour +93

Young, low-mass Brown Dwarfs orbiting early-type stars, with low mass ratios (), appear intrinsically rare and present a formation dilemma: could a handful of these…
