GW170104
k spisku chernyh dyr s izvestnymi massami.
Sliyanie dvuh men'shih chernyh dyr privelo k vydeleniyu ogromnoi energii i bylo
zaregistrirovano
Lazerno-interferometricheskoi gravitacionno-volnovoi observatoriei
(Laser Interferometer
Gravitational-wave Observatory –
LIGO).
Eto –
tretii
sluchai obnaruzheniya gravitacionnyh voln.
Tol'ko chto obnaruzhennaya chernaya dyra imeet massu okolo 49 mass Solnca, chto
zapolnyaet probel mezhdu massami dvuh slivshihsya chernyh dyr, ranee zaregistrirovannyh LIGO.
Ih massy byli bol'she solnechnoi v
62 raza
(GW150914) i v 21 raz
(GW151216).
Vo vseh treh sluchayah signal na kazhdom iz dvuh odinakovyh detektorov LIGO byl
odnoznachno identificirovan kak ishodyashii ot sliyaniya chernyh dyr, a v chetvertom sluchae
(LVT151012) stepen' dostovernosti registracii gorazdo men'she.
Ocenka rasstoyaniya do
GW170104
– okolo 3 milliardov svetovyh let, eto dal'she, chem prinyatye v nastoyashee vremya
ocenki dlya
GW150914 i GW151216.
Volny v prostranstve-vremeni
byli obnaruzheny vo vremya osushestvlyayushegosya v nastoyashee vremya cikla nablyudenii na LIGO,
kotoryi nachalsya 30 noyabrya 2016 goda i prodolzhitsya vse leto.
