Chemical evolution in high-mass star-forming regions
Francesco Fontani, Maria Teresa Beltrán, Anton Vasyunin
Growing evidence shows that most stars in the Milky Way, including the Sun, are born in high-mass star-forming regions, but due to both observational and theoretical challenges, ou…

Abundance anomalies in low mass field mergers as evidence of a merger origin for the second generation stars in globular clusters
Valery Kravtsov, Sami Dib, Francisco A. Calderon
The canonical formation of second-generation (G2) stars in globular clusters (GCs) from gas enriched and ejected by G1 (primordial) polluters faces substantial challenges, i.e. (i)…

QED cascade initiation via reflection of a multipetawatt laser pulse from a self-organized parabolic plasma mirror
M. A. Serebryakov, E. N. Nerush, L. Ji +2
The self-sustained or avalanche-type cascade is an intriguing prediction of strong-field quantum electrodynamics (QED) that has yet to be observed in laboratories. It is accompanie…
