Spatially resolved broad line region in a quasar at z=4: Dynamical black hole mass and prominent outflow
GRAVITY+ Collaboration, K. Abd El Dayem, N. Aimar +92
We present the first near-infrared interferometric data of a QSO at z=4. The K-band observations were performed with GRAVITY+ on the VLTI using all four UTs, detecting a differenti…

A systematically-selected sample of luminous, long-duration, ambiguous nuclear transients
P. Wiseman, R. D. Williams, I. Arcavi +12
We present a search for luminous, long-duration ambiguous nuclear transients (ANTs) similar to the unprecedented discovery of the extreme, ambiguous event AT2021lwx with a \,…

I Zw 1 and H0557-385: The Dusty Tori of Two High Eddington AGNs Observed in the MATISSE LM-Bands
Farin Drewes, James H. Leftley, Sebastian F. Hönig +2
The torus in Active Galactic Nuclei (AGN) is a complex dynamical structure of gas and dust. It is thought to be composed of an equatorial dusty disk and a polar dusty wind launched…
