Detection of gravitational waves

Click For Summary
SUMMARY

The current state of gravitational wave detection is primarily dominated by the LIGO observatory, which has only been able to place upper limits on the magnitude of gravitational waves. The next-generation instrument, LISA, is expected to enhance detection capabilities significantly. The discussion highlights the challenges in detecting gravitational waves from events such as neutron star mergers and black hole collisions, emphasizing the need for substantial changes in the gravitational field to produce detectable waves. Additionally, various operational gravitational wave detectors, including resonant mass detectors, are noted for their sensitivity.

PREREQUISITES
  • Understanding of gravitational wave physics
  • Familiarity with LIGO and LISA instruments
  • Knowledge of neutron star and black hole dynamics
  • Awareness of detection methodologies in astrophysics
NEXT STEPS
  • Research the operational principles of LIGO and LISA
  • Explore the theory behind gravitational wave generation from neutron star and black hole mergers
  • Investigate the sensitivity and design of resonant mass gravitational wave detectors
  • Study the implications of gravitational waves in cosmology and astrophysics
USEFUL FOR

Astronomers, astrophysicists, and students interested in gravitational wave research, as well as engineers and scientists involved in the development of detection technologies.

Would a neutron star collapse to a BH through accretion produce detectable waves?
I think that would depend upon how far away it would be. I honestly don't know how far away we could detect such events.

Well, maybe we'll all get lucky. Stranger things have happened... Maybe there are two 100x or more stellar mass BH's a 10 ly or so away about to merge perfectly perpendicular to the plane of LIGO! Fingers crossed everyone!

Hey, maybe this is the 2012 issue those lunatics go on about. We'll get full confirmation of GR/QM, then immidiately be accreted. :smile:

LOL Now that is an end of the world I would buy tickets for. I'd just hope we get slung into deep space... a literal spaceship earth.
