  2. Black hole - Wikipedia

    en.wikipedia.org/wiki/Black_hole

    It has also been suggested that some ultraluminous X-ray sources may be the accretion disks of intermediate-mass black holes. [182] Stars have been observed to get torn apart by tidal forces in the immediate vicinity of supermassive black holes in galaxy nuclei, in what is known as a tidal disruption event (TDE). Some of the material from the ...

    As of February 2019, 10 mergers of binary black holes have been observed. In each case two black holes merged to a larger black hole. In addition, one neutron star merger has been observed , forming a black hole. In addition, over 30 alerts have been issued since April 2019, of black hole merger candidates. GW 150914

    The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list.. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.

    When pairs of phonons were created near the analogue black hole, Steinhauer observed one particle falling in and the other escaping. This, he said, is analogous to a photon escaping a real black hole.

    A clockwise rotating black hole was observed in the 6σ region. [31] The image provided a test for Albert Einstein's general theory of relativity under extreme conditions. [17] [20] Studies have previously tested general relativity by looking at the motions of stars and gas clouds near the edge of a black hole.

    For many years, scientists similarly believe that the extreme environments near supermassive black holes prevented even single new stars from forming there before those were observed near ...

    First black hole discovered: first observed in 1964 in X-rays, first speculated as black hole in 1972, first confirmed black hole in 1975, accepted as a black hole by 1990 [ 26 ] [ 27 ] [ 23 ] See also

  9. List of gravitational wave observations - Wikipedia

    en.wikipedia.org/wiki/List_of_gravitational_wave...

    Known gravitational wave events come from the merger of two black holes (BH), two neutron stars (NS), or a black hole and a neutron star (BHNS). [9] [10] Some objects are in the mass gap between the largest predicted neutron star masses (Tolman–Oppenheimer–Volkoff limit) and the smallest known black holes.
