Hace 6 días · Gamma-ray bursts (GRBs) are the biggest explosions in the cosmos emitting large amounts of the most energetic form of light, gamma rays. GRBs shine hundreds of times brighter than a typical supernova (the explosive death of a massive star) and are about a million trillion times brighter than the Sun; yet they are short-lived, lasting from a few milliseconds to several minutes.
Hace 6 días · GAMMA RAY – Gira en España: Madrid y Bilbao en diciembre dentro de Z! LIVE ON TOUR. Recordamos la nota oficial, con los detalles: La mítica banda, liderada por Kai Hansen, actuará los días 4 y 5 de diciembre en Madrid y Bilbao. Las entradas ya están a la venta por 35 euros.
Hace 1 día · A high efficiency simulation method for propagation-based phase-contrast imaging, called directional macro-wavefront (DMWF), is developed with the aim of simulating high-energy phase-contrast imaging.
Hace 2 días · El detector infrarrojo, prosiguió el científico, ofrece la ventaja de observar objetos más viejos, por ello muy lejanos, como estallidos de rayos gamma originados en etapas tempranas del universo, cuando se estaban formando las galaxias. El telescopio podrá reaccionar con velocidad a alertas de ondas gravitacionales y detectores de neutrinos.
Hace 2 días · NASA’s BurstCube satellite has successfully detected a gamma-ray burst in outer space, achieving a major milestone in its mission. Despite being no larger than a shoebox, this tiny satellite is designed to monitor gamma-ray bursts from orbit. While such cosmic events can be immensely destructive, they also have the potential to create essential elements for life.
Hace 3 días · BurstCube, a shoebox-sized satellite designed by NASA, has made a historic breakthrough by detecting its first gamma-ray burst, one of the most powerful explosions in the universe. This achievement marks a significant step forward in the study of these cosmic phenomena, demonstrating the incredible potential of small satellite missions in space ...
Hace 5 días · 1.Introduction. Radiation from gamma-ray emitting radionuclides presents substantial health hazards due to its high penetrating power (Tchorz-Trzeciakiewicz et al., 2023).Gamma rays can easily penetrate the human body and most materials, making shielding and protection more difficult than with alpha and beta particles.
