GA-NIFS view of LAP1: Assembly of Pop~III stellar clusters during EoR

J. Scholtz, R. Maiolino, S. Carniani +28

Lensed and Pristine 1 (LAP1) is one of the most promising candidates for the detection of so-called Pop~III stars at . In this work, we present new high-spectral-resoluti…

DREAMS: Taking the Temperature of a Massive Galaxy at z ~ 11

L. Parente, E. Vanzella, M. Messa +15

We present a detailed photometric and spectroscopic analysis of Janus-11, a galaxy magnified by a factor 1.6 by the galaxy cluster MACS J0416. It was observ…

FEAST: a NIRSpec/MOS survey of emerging young star clusters in NGC 628

Helena Faustino Vieira, Angela Adamo, Neville Shane +18

JWST can pierce through dusty molecular clouds to study the early stages of star formation, where young star clusters are actively driving stellar feedback and still emerging from…

The emerging timescale of young star clusters regulated by cluster stellar mass

Alex Pedrini, Angela Adamo, Daniela Calzetti +23

Quantifying the timescales of star cluster emergence from their natal clouds remains one of the main challenges in understanding the star formation process. These timescales are fu…
