A Single Line-Emitter Identified in an Unbiased Search with JWST/NIRSpec: Multi-Object Coronagraphy for Slitless Spectroscopy
Mason S. Huberty, Claudia Scarlata, Matthew J. Hayes +13
We report the detection of a previously unknown object with a single emission line within the Hubble Ultra Deep Field, using a new JWST NIRSpec technique called Multi-Object Corona…
MOCSS: Multi-Object Coronagraphy for JWST/NIRSpec Slitless Spectroscopy
Mason S. Huberty, Claudia Scarlata, Matthew J. Hayes +10
We present an experimental JWST/NIRSpec observational method to obtain G140M/F100LP slitless spectroscopic observations. This "Multi-Object Coronagraphy for Slitless…
The formation of supermassive black holes from Population III.1 seeds. IV. Self-regulated seeding from supermassive star ionizing feedback
Maya A. Petkova, Jonathan C. Tan, Jasbir Singh +5
Supermassive Population III.1 stars, i.e., formed from pristine, metal-free gas leading to conditions where dark matter annihilation heating is significant, have been proposed as t…
BlackHoleWeather -- Spin-coupled chaotic cold accretion across the meso scale: Variability and kinematics
Olmo Piana, Massimo Gaspari, Vieri Cammelli +10
Supermassive black hole (SMBH) spin records the vector history of accretion. In chaotic cold accretion (CCA), this history is set by clouds and filaments whose torques can add cohe…
BlackHoleWeather -- Chaotic cold accretion across the meso-scale: Morphology and thermodynamics
Filippo Barbani, Massimo Gaspari, Vieri Cammelli +12
Supermassive black holes (SMBHs) self-regulate galaxies, groups, and clusters, yet the pathway transporting gas from halo scales to sub-pc radii remains debated. In hot stratified…
BlackHoleWeather -- Chaotic cold accretion across the meso-scale: Variability and kinematics
Filippo Barbani, Massimo Gaspari, Olmo Piana +12
Accretion onto supermassive black holes (SMBHs) in realistic halos is time-variable, governed by turbulence, cooling, and multiphase condensation. In chaotic cold accretion (CCA),…
BlackHoleWeather -- Jet-regulated chaotic cold accretion across the meso scale: Morphology and thermodynamics
Vieri Cammelli, Massimo Gaspari, Olmo Piana +11
How mechanical AGN feedback couples to multiphase condensation across scales remains a problem in galaxy groups and clusters. It is unclear how jets reshape the chaotic cold accret…
BlackHoleWeather -- Spin-coupled chaotic cold accretion across the meso-scale: Morphology and thermodynamics
Olmo Piana, Massimo Gaspari, Filippo Barbani +10
Supermassive black hole (SMBH) spin is a key but poorly constrained ingredient of the feeding-feedback loop. Chaotic cold accretion (CCA) of cold gas clouds delivers rapidly varyin…
Too many or too massive? Investigating the high- demography of active SMBHs from JWST
Daniel Roberts, Francesco Shankar, Vieri Cammelli +12
Recent JWST observations have unveiled a numerous population of low-luminosity active galactic nuclei (AGN) at , with space densities roughly an order of magnitude above p…
Glimmers in the Cosmic Dawn. III. On the Photometrically Determined Black Hole Mass to Stellar Mass Relation Across Cosmic Time
Alice R. Young, Matthew J. Hayes, Alberto Saldana-Lopez +7
We present the results from performing spectral energy distribution (SED) fitting on 121 variable active galactic nuclei (AGN) candidates in the Hubble Ultra Deep Field (HUDF) usin…
The Emergence and Ionizing Feedback of Pop III.1 Stars as Progenitors for Supermassive Black Holes
Mahsa Sanati, Jonathan C. Tan, Julien Devriendt +9
Recent observations by JWST reveal an unexpectedly abundant population of rapidly growing supermassive black holes (SMBHs) in the early Universe, underscoring the need for improved…
Glimmers in the Cosmic Dawn. II. A variability census of supermassive black holes across the Universe
Vieri Cammelli, Jonathan C. Tan, Alice R. Young +7
Understanding the origin and evolution of supermassive black holes (SMBH) stands as one of the most important challenges in astrophysics and cosmology, with little current theoreti…
Red, hot, and very metal poor: extreme properties of a massive accreting black hole in the first 500 Myr
Roberta Tripodi, Nicholas Martis, Vladan Markov +29
The James Webb Space Telescope (JWST) has recently discovered a new population of objects at high redshift referred to as `Little Red Dots' (LRDs). Their nature currently remains e…
The Origin of Supermassive Black Holes from Pop III.1 Seeds
Jonathan C. Tan, Jasbir Singh, Vieri Cammelli +4
The origin of supermassive black holes (SMBHs) is a key open question for contemporary astrophysics and cosmology. Here we review the features of a cosmological model of SMBH forma…
The formation of supermassive black holes from Population III.1 seeds. III. Galaxy evolution and black hole growth from semi-analytic modelling
Vieri Cammelli, Pierluigi Monaco, Jonathan C. Tan +5
We present an implementation of Pop III.1 seeding of supermassive black holes (SMBHs) in a theoretical model of galaxy formation and evolution to assess the growth the SMBH populat…
Glimmers in the Cosmic Dawn: A Census of the Youngest Supermassive Black Holes by Photometric Variability
Matthew J. Hayes, Jonathan C. Tan, Richard S. Ellis +10
We report first results from a deep near infrared campaign with the Hubble Space Telescope to obtain late-epoch images of the Hubble Ultra-Deep Field (HUDF), 10-15 years after the…
The optically elusive, changing-look active nucleus in NGC 4156
