伽马射线暴分为长暴和短暴，分别对应什么天体事件？
Gamma-ray bursts come in long and short types—what events do they correspond to?
长暴（持续数秒到几分钟）通常关联大质量恒星的坍缩，短暴（不到两秒）多来自双中子星或中子星-黑洞的并合。
Long bursts (seconds to minutes) are usually linked to collapsing massive stars, while short bursts (under two seconds) mostly come from mergers of two neutron stars or a neutron star and black hole.

有些伽马暴为什么会和超新星出现在同一位置？
Why do some gamma-ray bursts coincide with supernovae at the same location?
这类长伽马暴往往源于大质量恒星核心坍缩，坍缩本身触发超新星，而喷流击穿恒星外层产生伽马暴，所以二者常同源出现。
These long GRBs often arise from the core collapse of a massive star; the collapse triggers a supernova while jets punch through the star to make the GRB, so both share a common origin.

伽马射线暴为什么被称为宇宙中最亮的爆炸？
Why are gamma-ray bursts called the brightest explosions in the universe?
一次伽马暴在几秒到几分钟内释放的能量可堪比恒星一生的辐射，且集中于狭窄喷流，若在远处对准地球，瞬时亮度超过整个可见宇宙的其他天体总和。
A gamma-ray burst can release in seconds to minutes energy rivaling a star's whole lifetime, focused into narrow jets; if aimed at Earth from afar, its brief flash outshines everything else in the visible universe combined.
