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…
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…
