Hidden Figures of Globular Clusters: Integrated Stellar Populations Impacted by Hot Subdwarfs

The Astrophysical Journal
Globular clusters (GCs) are fundamental for understanding the integrated light of old stellar populations and galaxy assembly processes. However, the role of hot, evolved stars, such as horizontal branch (HB), extreme HB, and blue stragglers, remains ...

Primordial Stellar Populations

, 2002
We review the expected properties of the first stellar generations in the Universe. In particular, we consider and discuss the diagnostics, based on the emission from associated HII regions, that permit one to discern bona fide primeval stellar generations from the ones formed after pollution by supernova explosions has occurred. We argue that a proper

Age of Massive Galaxies at Redshift 8

The Astrophysical Journal
Recent James Webb Space Telescope data analyses have shown that massive red galaxies existed at redshifts z ≳ 6, a discovery that is difficult to understand in the context of standard cosmology (ΛCDM).
