Supermagnified Stars in Lensing Clusters and Small-Scale Structure in the Dark Matter

Gabriel Torralba, Jordi Miralda-Escudé

Supermagnified stars, discovered by HST and JWST in lensing clusters of galaxies, are luminous stars in source galaxies lying near lensing caustics that are magnified by large factors ($\sim 1000$), making them detectable at cosmological distances. Intracluster stars in the lens modify the large scale caustic into a corrugated network of micro caustics, causing frequent microlensing events of the supermagnified st...

Nuclear Fusion

Andrea Di Vita

This book offers an accessible overview of the diverse approaches being pursued to make fusion energy a reality. Rather than diving into the underlying physics or speculating over future predictions, Nuclear Fusion: At Last? focuses on what can be known today: the technologies, the experiments, the challenges, and the players shaping the field. Organised into four parts, the book begins with a broad introduction t...
