Observaciones de VLT/VIMOS del frente de choque del remanente de la supernova SN 1006
Nuevas observaciones muy detalladas de los restos de una supernova de mil años, llevadas a cabo con el telescopio VLT (Very Large Telescope) de ESO, han revelado claves sobre el origen de los rayos cósmicos.
La imagen de la izquierda muestra todo el remanente de la supernova SN 1006 supernova vista en ondas de radio (rojo), rayos X (azul) y luz visible (amarillo). La segunda imagen, que corresponde a la pequeña región cuadrada marcada a la izquierda, es una imagen más cercana del Telescopio Espacial Hubble de NASA/ESA de una región sorprendentemente estrecha del frente de choque, donde el material de la supernova choca con el medio interestelar. La tercera imagen muestra cómo la unidad de campo integral del instrumento VIMOS divide la imagen en muchas regiones pequeñas, luego la luz de cada una de ellas se divide los colores que componen su espectro. Cuando se analizan estos espectros, se pueden derivar los mapas de propiedades del objeto subyacente. El ejemplo que se muestra a la derecha es un mapa de una de las propiedades del gas (el ancho de la línea espectral), que es sorprendentemente variable, y que implica, junto con otros indicadores, la presencia de protones de muy altas velocidades.
