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 (…
Unsupervised selection and characterisation of Little Red Dots in JWST surveys with manifold learning
Michele Ginolfi, Filippo Mannucci, Alessandro Marconi +9
Little Red Dots (LRDs) are compact, red sources discovered at high redshift by JWST whose physical nature and selection function remain debated. We investigate whether an unsupervi…
Globular cluster abundance patterns inherited from giant molecular clouds
William McClymont, Vasily Belokurov, Sandro Tacchella +16
Globular clusters exhibit large star-to-star variations and anticorrelations in their light element abundances that are commonly interpreted in terms of in-cluster self-enrichment,…
How can we finally see the first light? Status and perspective in the search for Population III stars
Alessandra Venditti, Daniel Schaerer, Erik Zackrisson +28
Finding the first (Population III or Pop III) stars is one of the fundamental quests of astronomy, aiming to deliver the missing link in how stars form at early cosmic times. Yet t…
Unveil the nature of JWST-AGN and Little Red Dots with SKAO continuum surveys
Giovanni Mazzolari, Dharam V. Lal, Isabella Prandoni +6
The advent of JWST has revealed a large population of AGN at , which are dex more abundant than previously expected, including also the enigmatic population of Little…
No evolution in the number density of little red dots from cosmic dawn to cosmic noon
Federica Loiacono, Roberto Gilli, Marco Mignoli +24
We present our search for little red dots (LRDs) in the "J1030 field", a region of the sky around the quasar SDSS J1030+0524, observed by the JWST EIGER program. Over 1…
