Little red dot variability over a century reveals black hole envelope via a giant Einstein cross

Zijian Zhang, Mingyu Li, Masamune Oguri +79

"Little red dots" (LRDs) represent a new population of astronomical objects uncovered by JWST whose nature remains debated. Although many LRDs are suspected as active galactic nucl…

A deep X-ray look to the most obscured quasar at z~3.6 and its environment

I. Villani, L. Zappacosta, E. Piconcelli +17

The most luminous and obscured quasars (QSOs) detected in infrared all-sky surveys could represent a key co-evolutionary phase from nuclear to circum-galactic (CG) scales in the fo…

VENUS: A Strongly Lensed Clumpy Galaxy at behind the Galaxy Cluster MACS J0257.1-2325

Minami Nakane, Vasily Kokorev, Seiji Fujimoto +75

We present the discovery of a strongly lensed galaxy at , dubbed the ``Misty Moons'', identified in the JWST Treasury Survey, Vast Exploration for Nascent, Unexplored S…

BlackTHUNDER: Evidence of three massive black holes in a z~5 galaxy

Hannah Übler, 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…

BlackTHUNDER: Shedding light on a dormant and extreme little red dot at z=8.50

Gareth C. Jones, Hannah Übler, Roberto Maiolino +17

Recent photometric surveys with JWST have revealed a significant population of mysterious objects with red colours, compact morphologies, frequent signs of active galactic nucleus…

JADES reveals a large population of low mass black holes at high redshift

Sophia Geris, Roberto Maiolino, Yuki Isobe +24

JWST has revealed a large population of active galactic nuclei (AGN) in the distant universe, which are challenging our understanding of early massive black hole seeding and growth…

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…

BlackTHUNDER strikes twice: rest-frame Balmer-line absorption and high Eddington accretion rate in a Little Red Dot at

Francesco D'Eugenio, Roberto Maiolino, Michele Perna +29

JWST has revealed a population of 'Little Red Dots' (LRDs): compact, red objects at redshifts z=2-9 with 'v'-shaped spectral energy distributions, broad permitted lines, and, often…

BlackTHUNDER -- A non-stellar Balmer break in a black hole-dominated little red dot at

Xihan Ji, Roberto Maiolino, Hannah Übler +34

Recent observations from JWST have revealed an abundant population of active galactic nuclei (AGN) and so-called ``Little Red Dots'' (LRDs) at , many of wh…
