An international team reports a rare link between a binary black hole merger (GW event S241125n, about 4.2 billion light-years away) and a short gamma-ray burst with an X-ray afterglow, suggesting such mergers can emit detectable light under certain conditions and signaling a new era for combining gravitational waves with electromagnetic observations.
Astronomers observed GRB 250702B, a gamma-ray burst with an unprecedented duration of nearly a day and possible repetition, originating from a large, dusty galaxy over five billion light-years away. Its unusual characteristics suggest it may result from an exotic event such as a massive star collapse, a tidal disruption event, or a black hole-star merger, potentially indicating a new type of cosmic explosion.
Astronomers have recorded the longest gamma-ray burst ever, GRB 250702B, lasting about 7 hours, which may have been powered by a black hole merging with a star, indicating a potentially new type of cosmic event beyond traditional models.
A 2019 gravitational wave event, GW190521, may be explained not only by a black hole collision but also by the possibility of a wormhole linking universes, though the black hole explanation remains more likely. This discovery opens new avenues for exploring exotic physics and the nature of our universe.
A recent black hole merger detected by LIGO and other observatories provides the clearest evidence yet supporting Einstein's General Relativity, Hawking's area theorem, and Kerr's black hole model, confirming key predictions about black hole properties and their connection to fundamental physics, with future detectors promising even deeper insights.
Scientists have detected a recoil or 'kick' from a black hole formed by the merger of two black holes, using gravitational wave data from 2019. The event, GW190412, involved black holes of 8 and 30 solar masses, located 2.4 billion light-years away, with the resulting black hole being propelled at 31 miles per second. This observation provides new insights into black hole dynamics and the potential for studying such events through gravitational waves and electromagnetic signals.
Scientists have measured the recoil velocity and direction of a black hole formed from a merger, using gravitational wave data from the 2019 event GW190412, revealing the black hole was kicked at over 50 km/s, demonstrating a new way to study black hole mergers and their dynamics.
Scientists have for the first time measured the speed and direction of a newborn black hole resulting from a merger, using gravitational wave data from LIGO and Virgo, revealing the black hole was ejected at 112,000 mph, providing new insights into black hole dynamics.
LIGO's latest detection of a gravitational wave from a black hole merger confirms key predictions by Stephen Hawking, including the size and description of black holes using mass and spin, marking a significant milestone in astrophysics and the study of strong-field general relativity.
Scientists using LIGO detected a black hole merger that confirms Stephen Hawking's 50-year-old theory that the event horizon of a black hole can never decrease in size, providing strong evidence for black hole thermodynamics and quantum effects near the horizon.
Scientists in the US have observed the largest black hole merger to date using gravitational wave detectors, revealing that black holes can undergo successive mergers to form even more massive black holes, with no impact on Earth as the event occurred billions of light years away.
LIGO-Virgo-KAGRA detected the most massive and fastest-spinning black hole merger ever, resulting in a black hole over 225 times the Sun's mass, challenging existing theories of black hole formation and pushing the limits of gravitational wave detection technology.
This week in science saw groundbreaking discoveries including the largest black hole merger, volcanic activity in Iceland driven by underground 'blobs', Japan setting a new internet speed record, psilocybin in magic mushrooms showing potential anti-aging effects, and insights into Earth's weakening magnetic field from ancient artifacts.
Astronomers observed the most massive black hole collision to date, GW231123, involving black holes likely formed through previous mergers, challenging existing theories of black hole formation and highlighting the rapid advancement of gravitational wave astronomy.
The largest black hole merger ever observed, detected by LIGO and its international partners, involved two massive, rapidly spinning black holes and occurred billions of light years away, challenging current understanding of black hole formation and pushing the limits of gravitational wave detection technology.
