RE: Astronomy News #05 - Gravitational waves, black holes & star clusters
(note: graviton is still not confirmed)
Good luck with that. I have no idea how we could directly observe a graviton, its interactions being so gravitationally weak.
From 2015 11 sources of gravitational waves are confirmed, and since April 1, 2019, the new observational window is running with a current number of 28 candidates to be confirmed.
Thanks to a very nice alert system, any GW detection is accompanied by probes of cosmic ray, gamma ray or neutrino detection. We are in particular not supposed to detect yet any joint emission for what concerns the merging of two black holes (no sensitivity yet). However, seeing something may be extremely important as it may shake our understanding of what is going on there.
Yeah it would be so hard to see it - especially from the ground-based detectors. But given enough time, there is always a chance that something strange occurs - and Nobel prize goes to a lucky observer(or will be taken away from him). :D
I have heard rumours (which I won't make more explicit on chain :D ) and I am looking forward for the first public results of the O3 GW run!
Oh my, tell me more, tell me more! :)
With all the new boosted instruments its definitely nice time to be in the field of science once again. :)
Industry sucks anyways :P :)
