UK: Indian-Origin Astrophysicist, Professor Vik Dhillon, Shines Light on Universe's Mysteries

News 18  

Professor Vik Dhillon, an Indian-origin astrophysicist from the University of Sheffield in the UK, is part of a team that has brought humanity closer to understanding how the heaviest chemical elements are created in the universe using a high-end camera. A kilonova, resulting from the fusion of two dense neutron stars, holds significance as it’s thought to be the source …

The illusion of being faster than light: how black holes are formed through the merging of neutron stars

The Hindu  

Mooley, K.P., Anderson, J. From this, scientists, piecing together evidence from complementary measurements, surmised that the event they had observed was of two neutron stars merging and forming a black hole and, in the process, giving off light. This resolves the earlier fuzziness about what the source was and puts the source clearly as massive neutron stars merging to give …

Gravitational Waves Caused by Collision of Neutron Star and Black Hole Detected

News 18  

Scientists have for the first time detected gravitational waves — ripples in the fabric of space-time — produced by the collision of a neutron star and a black hole. The finding confirms that there are systems consisting of a neutron star and a black hole, and will help answer many questions about the cosmos, from star formation to the expansion …

Neutron star and a pulsar are stuck in a 'fiercely tight' orbit

Daily Mail  

Astronomers have observed two collapsed stars spinning rapidly around each other in a doomed dance. A neutron star, the ultra-dense remains of a once vast star, is believed to be in a 'fiercely tight' orbit around a pulsar. It is highly unusual to observe two neutron stars orbiting each other in a binary system in this way, scientists say, and …

New beast: Astronomers detect another rare blue optical transient in the universe, 500 million-light-years-away

Firstpost  

This explosion has taken scientists by surprise because of its speed and heaviness of the material outflows. They found out that that blue light was known to have been a result of a fast blue optical transient that was described as a new form of an explosion in the universe. The recent one called CSS161010, short for CRTS-CSS161010 J045834-081803, has …
