| Sub‑topic | Key Points | |-----------|------------| | | First detected by the Vela satellites (1967); confirmed as cosmic phenomena in the 1970s. | | Classification | Short‑duration (<2 s) vs. long‑duration (>2 s) bursts; different progenitor models. | | Importance | Probes of extreme physics (relativistic jets, magnetic reconnection), cosmology (high‑z star formation), and multimessenger astronomy (gravitational waves, neutrinos). |
series, questions are frequently divided into "Level-A" (simple, conceptual for most entrance exams) and "Level-B" (challenging, multi-concept problems for JEE Advanced).
