Cousins says he is “hopeful” that the findings of gravitational-wave cosmology will be able shed more light on the Hubble ...

Astronomers have spotted the most distant and brightest "space laser" ever seen, blasting out from a distant galaxy collision ...

Pune: Researchers have devised a clever method to correct distance errors in galaxy measurements, making our maps of the universe and our understandin.

Gravitational lensing is used to make cosmic maps of matter, most of which is dark matter, and study how structure in the Universe grows.

Abstract: This work is about the application of redshift in the area of electromagnetism and curved space-time. In this research, an estimation of the mass of the stars BAT99 105 (BREY 77), BAT99 99 ...

A soaring cosmic symphony surrounds us; its notes emerge from massive celestial objects crashing together hundreds of millions or even billions of light-years away. But scientists have only tuned into ...

A rare supernova whose light traveled more than 10 billion years to reach Earth is offering astronomers an unexpected opportunity to probe one of cosmology’s biggest mysteries. The explosion, known as ...

Astronomers have discovered a cosmic radio laser which scientists call a hydroxyl megamaser that exists in a merging galaxy which lies more than 8 billion light-years away and discovered this through ...

Add Yahoo as a preferred source to see more of our stories on Google. A new “stochastic siren” method uses the gravitational-wave background to sharpen estimates of the Hubble constant. (CREDIT: NASA) ...

We explore the hypothesis that both Newtonian and relativistic gravitational phenomena may emerge from critical dynamics in nonlinear relativistic wave fields, in analogy with wave–particle duality in ...
