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…
Observing exoplanets from Antarctica in two colours: Set-up and operation of ASTEP+
François-Xavier Schmider, Lyu Abe, Abdelkrim Agabi +12
On December 2021, a new camera box for two-colour simultaneous visible photometry was successfully installed on the ASTEP telescope at the Concordia station in Antarctica. The new…
Intensity Interferometry observations of the H envelope of Cas with MéO and a portable telescope
Nolan Matthews, Jean-Pierre Rivet, David Vernet +9
We report on observations of the extended environment of the bright Be star -Cas performed using intensity interferometry measurements within its H emission line. These obser…
Building a GRAVITY+ Adaptive Optics Test Bench
The Gravity Plus Consortium, Florentin Millour, Philippe Berio +22
We present the testbench aimed at integrating the GRAVITY+ adaptive optics GPAO. It consists of two independent elements, one reproducing the Coud{é} focus of the telescope, includ…
Observation Scheduling and Automatic Data Reduction for the Antarctic telescope, ASTEP+
Georgina Dransfield, Djamel Mekarnia, Amaury H. M. J. Triaud +13
The possibility to observe transiting exoplanets from Dome C in Antarctica provides immense benefits: stable weather conditions, limited atmospheric turbulence, and a night that la…
The VAST Survey - IV. A wide brown dwarf companion to the A3V star Delphini
R. J. De Rosa, J. Patience, K. Ward-Duong +10
We report the discovery of a wide co-moving substellar companion to the nearby ( pc) A3V star Delphini based on imaging and follow-up spectroscopic observations o…
