It was thought that the most massive stars explode completely, leaving no black holes, so none exist in the 50 to 130 solar mass range. New observations found several such anomalies with low spin. The reason lies in the nuclear reaction rate inside stars, which shifts the boundaries of what's possib

Байесовский ансамбль уравнений состояния, построенный на гауссовских процессах, восстанавливает термодинамику холодной сверхплотной материи без предвзятых параметризаций. Ограничения от рентгеновских наблюдений NICER и гравитационно-волнового сигнала GW170817 заставляют скорость звука сначала взлете

Data from the Gaia satellite allowed a double check of gravity: how stars rotate and how they oscillate up and down. No modified gravity variant could explain both motions at once. But the invisible dark matter cloud handled it effortlessly. This is a strong argument that dark matter is real, and Ei

Weaving together NICER, LIGO, and heavy pulsar observations with neural networks and quantum chromodynamics equations, scientists have for the first time imposed a tight constraint on the color-flavor locking parameter (ΔCFL < 66 MeV) — half as wide as previous model estimates. It turns out that col

For the first time, a collapsing supernova is reliably linked to high-energy neutrinos. IceCube detected four neutrino events clustered in time and space near the peak brightness of SN 2021foa, a rare Type IIn supernova. The energy of the neutrino burst exceeded the optical by two orders of magnitud

Using a flexible mixed population model, scientists discovered a striking coincidence: the mass distribution of high-spin black holes exactly matches the distribution of remnant masses from the low-spin subpopulation. This ‘smoking gun’ proves that rapidly spinning black holes arose from hierarchica
