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…
NOEMA$^\rm{3D}$: A deep view of cold gas flows in a barred spiral galaxy at
Stavros Pastras, Reinhard Genzel, Linda J. Tacconi +35
We present a deep, high-resolution CO(4-3) IRAM-NOEMA observation of a main sequence, barred, spiral galaxy at , with an on-source integration time of hou…
Constraints on the host galaxy and AGN properties of three z > 6 JWST AGN from NOEMA observations
Giovanni Mazzolari, Hannah Übler, Rodrigo Herrera Camus +32
We targeted with deep NOEMA observations the [CII]158m emission of three JWST-discovered AGN at z>6. Two of them have the typical features of Little Red Dots (LRDs), while the t…
Resolved molecular gas and star-formation in massive unquenched spirals : I. UGC 8179
Romane Cologni, Simon Flesch, Philippe Salomé +7
Recent studies have uncovered a rare population of super-massive (M* > 1e11 Msun) star-forming spiral galaxies, Super Spiral Galaxies (SSGs), whose existence challenges classical q…
