Variability-selected AGN in dwarf galaxies: the incidence of AGN in dwarf and massive galaxies is similar
S. Kaviraj, D. De Cicco, I. Lazar +4
We use the VST-COSMOS survey to identify, via their optical broadband variability, 30 AGN in nearby (z<0.4) dwarf (10^8 MSun < M < 10^10 MSun) galaxies. VST-COSMOS offers a 1 deg^2…
The SEEDZ Simulations: Methodology and First Results on Massive Black Hole Seeding and Early Galaxy Growth
Lewis R. Prole, John A. Regan, Daxal Mehta +13
Here we introduce the SEEDZ simulations, a suite of cosmological hydrodynamic simulations exploring the formation and growth of the first massive black holes in the Universe. SEEDZ…
The MandelZoom project II: the impact of stellar feedback on black hole accretion through an -disc in dwarf galaxies with a resolved interstellar medium
Eun-jin Shin, Matthew C. Smith, Debora Sijacki +2
We present a suite of high-resolution simulations to study how different stellar feedback channels regulate the growth of central intermediate-mass black holes (IMBHs) in dwarf gal…
A direct black hole mass measurement in a Little Red Dot at the Epoch of Reionization
Ignas Juodžbalis, Cosimo Marconcini, Francesco D'Eugenio +37
Recent discoveries of faint active galactic nuclei (AGN) at the redshift frontier have revealed a plethora of broad \Halpha emitters with optically red continua, named Little Red D…
Exploring Spatially-Resolved Metallicities, Dynamics and Outflows in Low-Mass Galaxies at
L. R. Ivey, J. Scholtz, A. L. Danhaive +18
A majority of JWST/NIRSpec/IFU studies at high redshifts to date have focused on UV-bright or massive objects, while our understanding of low-mass galaxies at early cosmic times re…
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…
The MandelZoom project I: modelling black hole accretion through an -disc in dwarf galaxies with a resolved interstellar medium
Eun-jin Shin, Debora Sijacki, Matthew C. Smith +2
While mounting observational evidence suggests that intermediate mass black holes (IMBHs) may be important in shaping the properties of dwarf galaxies both at high redshifts and in…
MISTRAL: a model for AGN winds from radiatively efficient accretion in cosmological simulations
Marion Farcy, Michaela Hirschmann, Rachel S. Somerville +11
Feedback from active galactic nuclei (AGN) is crucial for regulating galaxy evolution. Motivated by observations of broad absorption line winds from rapidly accreting supermassive…
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…
