Neutrinos from a nearby galaxy reveal the secrets of a black hole

Neutrinos from a nearby galaxy reveal the secrets of a black hole

In the zoo of subatomic particles, neutrinos are strange beasts. Unlike more familiar particles such as electrons and protons, ghostly neutrinos barely interact with normal matter: they can fly through a planet as if it isn’t even there. This makes them extremely difficult to detect and, for neutrinos from cosmic objects in the sky, even …

Without more data, a black hole's origins can be "rotated" in any direction

Without more data, a black hole’s origins can be “rotated” in any direction

An MIT study reveals that, for now, the catalog of known black hole binaries does not reveal anything fundamental about how black holes form. Pictured is a simulation of light emitted by a supermassive black hole binary system where the surrounding gas is optically thin (transparent). Credit: NASA Goddard Space Flight Center Clues to a …

Genetic variants that offered protection during the Black Death are also associated with current autoimmune disorders – Neuroscience News

Summary: People with selected variants of the ERAP2 and TICAM2 genes were 40% more likely to survive the Black Death, the researchers found. However, in modern humans, those with the ERAP2 gene are more likely to suffer from autoimmune diseases such as Crohn’s disease. Source: University of Illinois Infectious diseases are among the strongest selective …

Credit: Cao et al, 2022 Using NASA’s Chandra and ESA’s XMM-Newton space telescopes, astronomers from Radboud University in the Netherlands and elsewhere made X-ray observations of a tidal disturbance event designated 3XMM J150052.0+015452, or J150052 for short. The results show that J150052 was triggered by a rapidly rotating …

Black hole 'carnivals' could produce the signals seen by gravitational wave detectors

Black hole ‘carnivals’ could produce the signals seen by gravitational wave detectors

Artist’s impression of a collection of black holes at the heart of a star cluster. Credit: ESA/Hubble, N. Bartmann Since 2015, the LIGO-Virgo-KAGRA collaboration has detected around 85 pairs of colliding black holes. We now know that Einstein was right: gravitational waves are generated by these systems as they wind around each other, warping spacetime …

Simulations predict existence of radio wave hotspots in black holes

Simulations predict existence of radio wave hotspots in black holes

Some of the synthetic images produced by the researchers show the hotspots spinning as an observer spins around the black hole’s spin axis. Credit: Crinquand et al Black holes, regions of spacetime where gravity is so strong that nothing can escape, are among the most fascinating and studied cosmic phenomena. Although there are now countless …

Study rules out primordial black holes originally clustered as dark matter candidates

Study rules out primordial black holes originally clustered as dark matter candidates

Pixabay. Primordial black holes (PBH) are fascinating cosmic bodies that have been widely studied by astrophysicists around the world. As their name suggests, these are black holes that would have appeared in the early days of the universe, less than a second after the Big Bang. Physics theory suggests that in the split second before …
