Standard: (\delta t_\textobs = \fracR2\Gamma^2 c (1+z) \Rightarrow \Gamma = \sqrt \fracR (1+z)2 c \delta t_\textobs ). Assume (R \sim c \times t_\textengine) but minimal (R) = ( c \times) (engine timescale) ≈ (c \times) break? Simpler: Use (\Gamma > \sqrt \fracc T2 \delta t_\textobs ) with (T) not given. Actually : $\Gamma > \sqrt \frac1+z2 \fracT\delta t $ but typical competition gives $T$ from light curve envelope. Without $T$, use: Minimum possible (R \sim 2\Gamma^2 c \delta t/(1+z)) must be > (R_g) of black hole? No — better: Use known relation : (\Gamma > 100 \left( \frac0.01\texts\delta t \frac1+z2 \right)^1/2) — plug $z=1,\delta t=0.01$: (\Gamma > 100). (This is standard lower limit). Whenever you get a Level 2 problem wrong,
Search again for – but this time, look deeper. Check the IOAA training forums, ask your coach, or request access from your national olympiad committee. The document exists, and it will change how you see gamma-ray bursts forever. Mastering these core segments is essential for securing
One of the most common pitfalls in GRB problems is mixing up the Doppler factor for the prompt emission (( \delta_D = [\Gamma(1-\beta\cos\theta)]^-1 )) versus the afterglow. The new PDF:
