Black Hole Feedback, Galaxy Quenching and Outflows at Cosmic Dawn: Analysis of the SEEDZ Simulations

Kavli Affiliate: Martin Haehnelt | Summary:Here we analyse the growth and feedback effects of massive black holes (MBHs) in the SEEDZ simulations. The most massive black holes grow to masses of $sim10^6$ M$_odot$ by $z=12.5$ during short bursts of super-Eddington accretion, sustained over a period of 5-30 Myr. We find that the determining factor that […]

Lightcurve Modelling of 2,205 ZTF DR2 Type~Ia Supernovae: Implications for SN Ia Physics and Cosmology

Kavli Affiliate: Kaisey Mandel | Summary:We fit the multi-band light curves of 2,205 Type Ia supernovae (SNe~Ia) from the Zwicky Transient Facility DR2 with a one-zone radioactive decay model with a phenomenological addition to include Fe recombination physics. We find a strong correlation between inferred nickel mass and SALT2 stretch, which within our simplified modelling […]

TORRCH: Tomographic reconstruction of the reionization of cosmic hydrogen with Ly$α$ emitters and non-Ly$α$-selected galaxies

Kavli Affiliate: Martin Haehnelt | Summary:Tomographic reconstruction of reionization is a long-sought goal. It would move the field beyond global summary statistics, such as the volume-averaged ionised fraction, to direct, field-level constraints on the ionization topology. With this in mind, we present TORRCH (TOmographic Reconstruction of the Reionization of Cosmic Hydrogen), a deep-learning framework that […]

Undermassive Hosts of $z = 4-6 $ AGN from JWST/NIRCam Image Decomposition with CONGRESS, FRESCO, and JADES

Kavli Affiliate: Roberto Maiolino | Summary:In the local Universe, supermassive black hole (SMBH) masses strongly correlate with their host-galaxies’ stellar masses ($M_*$), but galaxies hosting faint AGN recently found by JWST may deviate from this relation. To constrain the M$_textBH$-M$_*$ relation at high redshift, we performed AGN-host image decomposition for 17 low-luminosity AGN galaxies at […]

JADES: Discovery of Large Reservoirs of Small Dust Grains in the Circumgalactic Medium of Massive Galaxies at $zsim3.5$ through Deep JWST/NIRCam Imaging and Grism Spectroscopy

Kavli Affiliate: Roberto Maiolino | Summary:Using JWST NIRCam imaging and grism spectroscopy from the JWST Advanced Deep Extragalactic Survey (JADES) Origins Fields, we report spectroscopic redshift measurements of 1,445 emission-line galaxies at $z=0-9$. Within this sample, we identify two prominent galaxy protoclusters at $z = 3.47$ and 3.69, each anchored by massive dusty star-forming galaxies […]

JADES: A Prominent Galaxy Overdensity Candidate within the First 500 Myr

Kavli Affiliate: Roberto Maiolino | Summary:We report a galaxy overdensity candidate at $zapprox 10.5$ in the JWST Advanced Deep Extragalactic Survey (JADES). This overdensity contains 18 galaxies with consistent photometric redshifts and robust F115W dropouts within 8 comoving Mpc in projection. The galaxy number density is four times higher than the field expectation, accounting for […]
