Explosión de rayos gamma en un colapso estelar. Hablamos con Tomás Ahumada.

from Cienciaes.com

Desde los confines del universo llegan los fogonazos de radiación gamma procedentes de fenómenos que liberan en apenas un segundo tanta energía como la galaxia entera. En las cercanías de Tierra existen telescopios espaciales diseñados para rastrear el firmamento en busca de esas enormes demostraciones de energía. Se piensa que algunas de esas explosiones tienen su origen en estrellas muy masivas que, una vez agotado su combustible nuclear, colapsan bruscamente hasta formar una estrella de neutrones o un agujero negro, otras se originan durante la colisión de dos estrellas de neutrones. Los fogonazos de rayos gamma que desprenden esos cataclismos pueden viajar durante miles de millones de años hasta llegar a la Tierra donde son estudiados por investigadores como nuestro invitado, Tomás Ahumada, astrónomo chileno de la NASA y la Universidad de Maryland. El 26 de agosto de 2020 tuvo lugar uno de esos destellos y su estudio revela aspectos desconocidos que Tomás Ahumada y un nutrido número de investigadores revelan en un artículo científico publicado en la revista Nature Astronomy.
