GRAVITY-RESOLVE: A comprehensive image reconstruction tool for Galactic Center observations with GRAVITY
K. Abd El Dayem, N. Aimar, P. Amaro-Seoane +83
We aim to improve and extend the imaging capabilities of the GRAVITY beam combiner instrument of ESOs VLTI with respect to reconstruction software in the Galactic Center. We revise…
A first look at the protoplanet WISPIT 2 b with VLTI/GRAVITY+
GRAVITY+ Collaboration, K. Abd El Dayem, R. Abuter +116
Confirmed observations of young protoplanets actively undergoing the process of formation have remained rare to date. In this Letter, we present new insights into the nature of the…
Searching for Nearby Supermassive Black Hole Binaries with GRAVITY
GRAVITY Collaboration, K. Abd El Dayem, N. Aimar +82
We present a systematic interferometric search for close supermassive black hole (SMBH) binaries in 20 nearby type 1 active galactic nuclei (AGN) observed with VLTI/\grav. We inves…
Improving constraints on the Yukawa correction at the Galactic Center with multiple stellar orbits
GRAVITY+ Collaboration, :, A. Foschi +78
We investigate the presence of a Yukawa-like correction () to Newtonian gravity at the Galactic Center, using a multi-star fitting code, including the newly…
Using VLTI/GRAVITY+ to determine the identity of a third planet candidate in the PDS 70 system
David Trevascus, Wolfgang Brandner, Olga Balsalobre-Ruza +75
Detections of protoplanets are rare and protoplanetary disk features mischaracterized as planets are common. PDS 70 is one of only two stars known to host multiple confirmed protop…
