Scientists to provide update on the search for gravitational waves

10 February 2016 Astronomy Now

This year marks the 100th anniversary of the first publication of Albert Einstein’s prediction of the existence of gravitational waves. With interest in this topic piqued by the centennial, researchers from UK universities in Glasgow, Birmingham, and Cardiff will discuss their ongoing efforts to observe and measure cosmic gravitational waves for scientific research in London on Thursday, 11 February.

Where Alice in Wonderland meets Albert Einstein

The latest results from the “Cheshire Cat” group of galaxies 4.6 billion light-years away in the constellation Ursa Major show how manifestations of Einstein’s 100-year-old Theory of General Relativity can lead to new discoveries today. Astronomers have given the group this name because of its resemblance to the smiling feline from Alice’s Adventures in Wonderland.

Pairs of supermassive black holes in galaxies may be rarer than previously thought

22 September 2015 Astronomy Now

There may be fewer pairs of supermassive black holes orbiting each other at the cores of giant galaxies than previously thought, according to a new study. When two massive galaxies harbouring supermassive black holes collide, their black holes ultimately combine — a process that could be the strongest source of elusive gravitational waves, still yet to be directly detected.

Newly dedicated observatory to search for gravitational waves

20 May 2015 Astronomy Now

Seeking to expand how we observe and understand phenomena such as supernovae and colliding black holes that generate gravitational waves, the National Science Foundation has just dedicated the Advanced Laser Gravitational Wave Observatories (Advanced LIGO) in Richland, Washington and Livingston, Louisiana.
