  • Fast X-ray Transients (FXTs)

    Why in the news?

    Astronomers from the Indian Institute of Astrophysics have traced the likely origin of a rare Fast X-ray Transient (FXT) event, EP241107a, detected by the Einstein Probe in November 2024.

    Key Findings

    • FXTs are energetic, non-repeating flashes of X-rays lasting from a few minutes to several hours.
    • They are a recently discovered class of transient cosmic events whose origin has remained uncertain.
    • Researchers identified a radio counterpart of FXT EP241107a using the Karl G. Jansky Very Large Array.
    • Follow-up observations were conducted using:
      • Himalayan Chandra Telescope
      • GROWTH India Telescope
      • Upgraded Giant Metrewave Radio Telescope

    Likely Origin

    • The event was probably caused by: Collapse of a massive star leading to a supernova and gamma-ray burst (GRB), or Merger of two neutron stars.
    • Researchers concluded that EP241107a is most likely an “orphan afterglow”:
      • A gamma-ray-burst-like explosion whose gamma rays were not directly detected.
      • Represents a lower-energy member of the GRB population.

    Fast X-ray Transients (FXTs)

    • Sudden flashes of low-energy X-rays.
    • Non-repeating and short-lived.
    • Fade rapidly after detection.
    • Associated with highly energetic cosmic explosions.

    Proposed Sources

    • Core-collapse supernovae.
    • Binary neutron star mergers.
    • Magnetars (highly magnetized neutron stars).
    • Tidal disruption events involving white dwarfs and black holes.
    • Gamma-ray bursts (GRBs).

    Gamma-Ray Bursts (GRBs)

    • Most energetic explosions known in the Universe.
    • Emit intense gamma radiation for a few milliseconds to several minutes.
    • Associated with the collapse of massive stars (Long GRBs) and Neutron star mergers (Short GRBs).
    • Followed by multi-wavelength “afterglows” in X-ray, optical, and radio bands.

    Neutron Star

    • Extremely dense remnant of a massive star after a supernova.
    • Mass ≈ 1.4-2 solar masses compressed into a sphere about 20 km across.
    • Composed mainly of neutrons.

    [2023] Consider the following pairs: Objects in space : Description
    1. Cepheids : Giant clouds of dust and gas in space
    2. Nebulae : Stars which brighten and dim periodically
    3. Pulsars : Neutron stars that are formed when massive stars run out of fuel and collapse
    How many of the above pairs are correctly matched ?
