The data give better constraints than next-generation ground-based experiments can hope to achieve, highlighting the power of astronomy in testing subatomic physics.Axions and axion-like particles (ALPs) are hypothetical, chargelessparticles that rarely interact with.

W W …Īstronomers Rein in Possibilities for Exotic Particle - Sky & TelescopeĪstronomers observing a distant galaxy have dramatically shrunk the range of possible properties of a long-predicted - but never-detected - subatomic particle.An international team of scientists has used observations of the galaxy NGC 1275 to understand the possible properties (and existence) of an exotic type of particle. Now, future deep space missions may use a more to get a fix on their location: the beating hearts of dying stars, known as pulsars.Pulsars, also referred to as neutron stars, are the swiftly spinning remnant cores of core-collapse supernovae. Early explorers used a sextant and compass to gauge the position of the stars at sea, and modern travelers use satellite-enabled GPS technology. A famous.… NICER and SEXTANT demonstrate XNAV pulsar navigation system that may be used on Artemis.As long as explorers have traversed Earth's surface, getting an accurate fix on location has been essential.

This asymmetry made the “hum” of overtones in the gravitational waves clear for the. But the new event, called GW190412, involved objects of about 8 and 30 solar masses, respectively. All 10 black hole mergers detected in the first two observing runs had binary components with similar masses. This asymmetry made the “hum” of overtones in the gravitational waves clear for the.… For the first time, the LIGO and Virgo gravitational-wave detectors have “heard” gravitational waves from an unequal pair of black holes.Scientists working with the LIGO and Virgo gravitational-wave observatories have detected an oddball event: the merger of two black holes of notably different sizes.
