The Line of Death, Ignoring Theories, and Other Stops in the Hunt for Bursts
did not follow the fireball model, but later peaks in the data might. "They can change their behavior," he said, "so the model is not invalidated." "The gamma ray spectrum does not tell if [a burst] is worthwhile to look for a counterpart," Palmer said. "So...
Dodging pitfalls in the hunt for the cause of gamma-ray bursts
"It falls out around 200 keV. But why it should be that particular value, and why you don't very often have bursts that are 10 times that or one-tenth is a mystery." 220 keV is the intersection of two lines drawn in a power law. It's basically two straight-line graphs,...
Taking a ringside seat for a gamma-ray burst
collapsar, the collapsing star scenario that is one of the leading contenders as the cause of gamma-ray bursts. The collapsar theory was proposed in 1993 by Dr. Stan Woosley of the University of California at Santa Cruz. Since 1996 his work on the collapsar...
Oregon State University: The Extreme Value Theorem
exists but does not say where. It is of some comfort to know that we can maximize profits, but the shrewd merchant wants to know how to set the price. Calculus gives us methods to solve problems of this nature and these methods are the subject of Sta...
Gamma-Ray Bursts Thought to be from Edge of Universe
from the Galactic center. The quadrupole moment is a measure of the tendency for bursts to appear in the plane of the Galaxy, like the stars in the band of the Milky Way. To measure of this property, the BATSE team takes the galactic latitude of...

Even the "soft" stars have a "hard" side
bursts or GRBs. Only in the last few years have scientists been able to establish that they come from galaxies several billion light years away, and thus occurred during the universe's youth. SGRs, meanwhile, have been linked with magnetars, neutron stars whose extreme magnetic...
