What is GRB Physics?

2. Solved Examples

  • Large number of solved problems, graded from easy to tough.
  • Problems are JEE-pattern (single correct, multiple correct, integer type, etc.).
  • Solutions are step-by-step and logical.
  • Afterglow physics (2 pages)
    • Lorentz factor estimates from variability: Γ ≥ (Lσ_T / (4π m_p c^3 R))^(1/3) — include simplified derivation
    • Synchrotron characteristic frequency, peak flux, cooling time
    • Deceleration time, radius relations

    Types of GRBs

    Rohan grabbed his notebook. For the first time, he wasn't solving for a block on an inclined plane. He was solving for a cosmic fireball. He calculated γ ≈ 22.4, the momentum, and the final velocity—which was still a fraction of c. He felt a chill: This is the same physics. The same momentum conservation. grb physics jee pdf
