A blast of gamma rays from space detected in June 2016 is helping astronomers resolve long-standing questions about the universe's most powerful explosions.
Using a wide array of ground- and space-based telescope observations, an international team led by University of Maryland astronomers constructed one of the most detailed descriptions of a gamma-ray burst to date. The event, named GRB160625B, revealed key details about the initial "prompt" phase of gamma-ray bursts and the evolution of the large jets of matter and energy that form as a result of the burst.
New maps of dark matter dynamics in the Universe have been produced by a team of international cosmologists.
A team of NASA-funded scientists will take to the skies during the Aug. 21 eclipse, using two of NASA's WB-57 jet planes to chase the shadow of the moon for unparalleled observations of the sun and Mercury.
Scientists have used data from the intergalactic medium -- the vast, largely empty space between galaxies -- to narrow down what dark matter could be.
NASA's Van Allen Probes have observed a new population of space sound waves, called plasmaspheric hiss, which are important in removing high-energy particles from around Earth that can damage satellites.
The death of a massive star in a distant galaxy 10 billion years ago created a rare superluminous supernova that astronomers say is one of the most distant ever discovered. The researchers reported their findings in a paper published on July 21 in the Monthly Notices of the Royal Astronomical Society.
The death of a massive star in a distant galaxy 10 billion years ago created a rare superluminous supernova, one of the most distant ever discovered. The brilliant explosion, more than three times as bright as the 100 billion stars of our Milky Way galaxy combined, occurred about 3.5 billion years after the big bang at a period known as 'cosmic high noon,' when the rate of star formation in the universe reached its peak.
A web that passes through infinite intergalactic spaces, a dense cosmic forest illuminated by very distant lights and a huge enigma to solve. These are the picturesque ingredients of a scientific research -- carried out by an international team composed of researchers from SISSA and the ICTP in Trieste, the Institute of Astronomy of Cambridge and the University of Washington - that adds an important element for understanding one of the fundamental components of our Universe: the dark matter.
Researchers at IMS and their coworkers have shown theoretically and experimentally that a high energy electron in circular/spiral motion radiates vortex photons in the entire wavelength range from the radio-wave to the gamma-rays. This greatly broadens application spectra of the vortex photons in the field of physical science. Moreover, the finding indicates that vortex photons are ubiquitous in the universe. It paves a way to a completely new research field, natural vortex photon science.
