  2. Graviton - Wikipedia

    en.wikipedia.org/wiki/Graviton

    Alternatively, if gravitons are massive at all, the analysis of gravitational waves yielded a new upper bound on the mass of gravitons. The graviton's Compton wavelength is at least 1.6 × 10 16 m , or about 1.6 light-years , corresponding to a graviton mass of no more than 7.7 × 10 −23 eV / c 2 . [ 18 ]

    For such gravitons to be detected, the team admits that it needs a pretty energetic gravitational wave, but their calculations suggest that one such wave created by a neutron-star merger in 2017 ...

  4. First observation of gravitational waves - Wikipedia

    Although no neutrinos were detected, the lack of such observations provided a limit on neutrino emission from this type of gravitational wave event. [69] Observations by the Swift Gamma-Ray Burst Mission of nearby galaxies in the region of the detection, two days after the event, did not detect any new X-ray, optical or ultraviolet sources. [70]

  5. Gravitational wave - Wikipedia

    en.wikipedia.org/wiki/Gravitational_wave

    A pulsar emits beams of radio waves that, like lighthouse beams, sweep through the sky as the pulsar rotates. The signal from a pulsar can be detected by radio telescopes as a series of regularly spaced pulses, essentially like the ticks of a clock. GWs affect the time it takes the pulses to travel from the pulsar to a telescope on Earth.

  6. LIGO - Wikipedia

    Plans call for the glass mirrors and 1064 nm lasers to be replaced by even larger 160 kg silicon test masses, cooled to 123 K (a temperature achievable with liquid nitrogen), and a change to a longer laser wavelength in the 1500–2200 nm range at which silicon is transparent. (Many documents assume a wavelength of 1550 nm, but this is not final.)

    It was published in 2020 that a gamma-ray burst was detected ~0.5 seconds after the LIGO trigger, lasting 6 seconds and bearing similarities to GRB170817 (such as weakness [most power in sub-100 keV, or soft X-rays) bands], elevated energetic photon background levels [signal exceeding background by less than a factor of 2], and similar ...

    The cosmic microwave background, radiation left over from when the Universe cooled sufficiently for the first atoms to form, can contain the imprint of gravitational waves from the very early Universe. The microwave radiation is polarized. The pattern of polarization can be split into two classes called E-modes and B-modes.

    A new blood test was found to detect colon cancer with more than 80% accuracy — and to rule it out for 90% of healthy people. Doctors speak about how this could improve screening rates and outcomes.
