伽马射线暴中相对论喷流对热茧辐射的逆康普顿散射的某些意义

Some Implications of inverse-Compton Scattering of Hot Cocoon Radiation by relativistic jets in Gamma-Ray Bursts

Pawan Kumar, George F. Smoot

摘要:

长伽马射线暴(GRB)的相对论喷流被热茧包围,热茧在喷流从祖星冲出时限制喷流。这些茧是X射线光子的丰富来源,这些X射线光子可以被相对论性喷流中的电子逆康普顿(IC)散射到MeV-GeV能量。我们提供了详细的估计IC流量之间的各种相互作用的X射线光子和相对论性喷流,并描述了我们可以了解伽玛暴喷流和祖星从检测(或上限)这些IC散射光子。

英文摘要:

Long Gamma-Ray Bursts (GRB) relativistic jets are surrounded by hot cocoons which confine jets during their punch out from the progenitor star. These cocoons are copious sources of X-ray photons that can be and are inverse-Compton (IC) scattered to MeV--GeV energies by electrons in the relativistic jet. We provide detailed estimates for IC flux resulting from various interactions between X-ray photons and the relativistic jet, and describe what we can learn about GRB jets and progenitor stars from the detection (or an upper limit) of these IC scattered photons.
