Mapping gas accretion and stellar kinematics to sub-kiloparsec scales in NGC 4696 with JWST/NIRSpec
Mathieu Marquis, Julie Hlavacek-Larrondo, Olivia Pereira +35
We present JWST/NIRSpec IFU spectroscopy of the central pc () of NGC 4696, the BCG in the Centaurus cluster. Leveraging the (…
JWST reveals how black holes are fed: kiloparsec-scale multiphase filaments feed sub-kiloparsec circumnuclear disks
Julie Hlavacek-Larrondo, Hyunseop Choi, Minghao Guo +35
The Centaurus cluster is one of the most important archetypes of radio-mode AGN feedback, with its central galaxy, NGC 4696, launching powerful jets that inflate X-ray cavities and…
BlackTHUNDER: Evidence of three massive black holes in a z~5 galaxy
Hannah Ãbler, Giovanni Mazzolari, Roberto Maiolino +41
We present observational evidence of three massive, accreting black holes (BHs) in the z=5.0167 galaxy J0148-4214 from JWST/NIRSpec-IFU spectroscopy. The BHs are revealed through b…
A black hole in a near-pristine galaxy 700 million years after the Big Bang
Roberto Maiolino, Hannah Uebler, Francesco D'Eugenio +36
The recent discovery of a large number of massive black holes within the first two billion years after the Big Bang, as well as their peculiar properties, have been largely unexpec…
Blueshifted lines from the inner accretion disc's rotation can explain quasar absorption "forests''
Amelia M. Hankla, Fergus J. E. Baker, Daniel R. Wilkins +1
Recent XRISM observations of active galactic nuclei such as PDS 456 have revealed ``forests'' of absorption lines best modeled by five distinct absorption zones with varying large…
The Cliff: A Metal-Poor Little Red Dot Hosting an Overmassive Black Hole at
Lucy R. Ivey, Francesco D'Eugenio, Roberto Maiolino +19
JWST has revealed a large population of massive black holes (BHs) in the early Universe with unusual properties which mark them as distinct from low-redshift active galactic nuclei…
