MEGATRON: Dwarf Galaxy Quenching in the Epoch of Reionization

David Attard, Ilian T. Iliev, Martin P. Rey +3

Low-mass galaxies during the Epoch of Reionization are expected to form stars in short bursts separated by periods of inactivity, but what regulates this cycle, and how sensitive i…

MEGATRON: The Physical Origins of Steep UV Slopes at High Redshift

Harley Katz, Nicholas Choustikov, Aayush Saxena +7

The ultraviolet (UV) spectral slope, , serves as a fundamental probe of stellar population properties and interstellar medium conditions in galaxies. At high redshift, a small s…

The AURORA Survey: Determining the Production Mechanism for OI Emission in Star-forming Galaxies at Cosmic Noon

Leonardo Clarke, Alice E. Shapley, Zhiwei Shao +11

We analyze deep JWST/NIRSpec observations of 58 star-forming galaxies at in the AURORA survey to investigate the origin of the permitted OI emission feature.…

How can we finally see the first light? Status and perspective in the search for Population III stars

Alessandra Venditti, Daniel Schaerer, Erik Zackrisson +26

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…
