伽马射线暴是宇宙中最猛烈的爆炸,如果发生在附近,可能会破坏地球的大气层。这项编目工作由玛丽亚·吉奥瓦娜·戴诺蒂(Maria Giovanna ...
沃森教授和戴诺蒂教授是一个由50多名科学家组成的团队的成员,他们在爆炸发生后的几周,甚至几个月里,仔细研究了伽马射线暴的光线是如何到达地球的。他们说,结果是在测量距离的光学波长上观察到的有史以来最大的GRB目录。
虽然一次伽马射线暴释放的能量已经超过了太阳在整个恒星生命周期中所释放的能量总和,但整个伽马射线暴的持续时间却非常短暂。目前观测到的伽马射线暴,爆发持续时间最长的不过数千秒,最短的仅仅几毫秒。根据持续时间的统计情况,科学家们将伽马射线暴分为两类:一类是 ...
