Neutron Star-Black Hole Binary

A new study examines in what sense a neutron star-black hole binary could the ‘holy grail’ for testing gravity. The intermittent light emitted by pulsars, the most precise timekeepers in the universe, allows scientists to verify Einstein’s theory of relativity, especially when these objects are paired up with another neutron star or white dwarf that […]

Study Reveals Black Holes Can Block the Formation of New Stars

A new study from Johns Hopkins University reveals that massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, providing crucial new evidence that it is these jets of “radio-frequency feedback” streaming from mature galaxies’ central black holes that prevent hot free gas from cooling and […]

Astrophysicists One Step Closer to Figuring Out the Mysteries of the Milky Way

Using data from the Russian spacecraft RadioAstron, astrophysicists are one step closer to figuring out the mysteries of our galaxy’s core. Is matter falling into the massive black hole at the center of the Milky Way or being ejected from it? No one knows for sure, but a UC Santa Barbara astrophysicist is searching for […]

NuSTAR Sees Rare Blurring of Black Hole Light

NuSTAR observations reveal X-ray light streaming from regions near supermassive black hole Markarian 335. NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has captured an extreme and rare event in the regions immediately surrounding a supermassive black hole. A compact source of X-rays that sits near the black hole, called the corona, has moved closer to the […]

Our Universe May Have Emerged from a Black Hole in a Higher Dimensional Universe

New research from theoretical physicists at the Perimeter Institute proposes that our universe may have emerged from a black hole in a higher-dimensional universe. The big bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, what sparked it? Three Perimeter Institute researchers have […]
