Peering into the formation history of beta Pictoris b with VLTI/GRAVITY long baseline interferometry
GRAVITY Collaboration, M. Nowak, S. Lacour +65
Our objective is to estimate the C/O ratio in the atmosphere of beta Pictoris b and obtain an estimate of the dynamical mass of the planet, as well as to refine its orbital paramet…
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…
Effect of Electromagnetic Interaction on Galactic Center Flare Components
Arman Tursunov, Michal Zajaček, Andreas Eckart +5
Recently, near-infrared GRAVITY@ESO observations at have announced the detection of three bright "flares" in the vicinity of the Galactic center supermassive black…
Distribution of Radio Spectral Slopes of Galaxies in Optical Diagnostic Diagrams
Michal Zajaček, Andreas Eckart, Silke Britzen +1
For about 500 intermediate-redshift sources (), whose radio flux densities at are larger than 10 mJy, we performed additional observations at 4.85 GHz…
Observations of the 86 GHz SiO maser sources in the Central Parsec of the Galactic Centre
A. Borkar, A. Eckart, C. Straubmeier +8
We present results of 3 mm observations of SiO maser sources in the Galactic Centre (GC) from observations with the Australia Telescope Compact Array between , along the…
First M87 Event Horizon Telescope Results. V. Physical Origin of the Asymmetric Ring
The Event Horizon Telescope Collaboration
The Event Horizon Telescope (EHT) has mapped the central compact radio source of the elliptical galaxy M87 at 1.3 mm with unprecedented angular resolution. Here we consider the phy…
