Why GRB's?

  1. Feb 17, 2007 #1
    Well, needless to say, I am new to astrophysics...

    What do GRB's tell us?

    I know that there are a few satellites that detect and localize GRB's by detecting X-ray emissions... specifically HETE-2. But, it is unclear to me the reason for studying these. Do the X-ray emissions only localize the origin of the GRB?

    I am going to assume that we can measure their redshift, and make assumptions about the expanding (accelerating) universe.

    Also, it seems that there is no clear answer to the progenitors of long or short GRB's (especially short). Is that what we are after?

    Thanks in advance, and sorry for my ignorance... :blushing:
