merging neutron stars – Astronomy Now

Upgraded LIGO and Virgo stations observe multiple gravity wave events

5 May 2019 Astronomy Now

The LIGO and Virgo gravity wave observatories, recently upgraded to improve sensitivity, have detected five black hole and neutron star mergers in a single month.

Upgrades to gravity wave detectors promise more discoveries

3 April 2019 Astronomy Now

After major upgrades to improve sensitivity, the LIGO and Virgo gravitational wave observatories are set to begin a year of joint observations.

Cataclysmic neutron star merger generates powerful jet

27 February 2019 Astronomy Now

Astronomers studying the aftermath of the merger of two neutron stars have found what appears to be a powerful jet blasting through a shell of debris.

Gravity waves marked birth of merged hypermassive neutron star

14 November 2018 Astronomy Now

Detailed analysis of gravitational wave data collected last year indicating the merger of two neutron stars shows the result was a single massive neutron star, not a black hole.

Astronomers see birth of rare binary neutron star

12 October 2018 Astronomy Now

Astronomers have found an “ultra-stripped supernova” that created a second neutron star in a tight binary system, matching theoretical predictions for how such binaries are formed in otherwise disruptive blasts.

Neutron star merger generated illusion of superluminal jet

10 September 2018 Astronomy Now

The merger of two neutron stars, observed in August, created two powerful jets streaming away into space at nearly the speed of light, in agreement with theoretical predictions and shedding new light on gamma ray bursts.

Colliding neutron stars likely formed low-mass black hole

1 June 2018 Astronomy Now

Colliding neutron stars generated headlines last year after the detection of gravitational waves sweeping through the solar system. Follow-on X-ray observations indicate the cataclysmic merger formed a record low-mass black hole.

Neutron star merger yields new puzzle for astrophysicists

19 January 2018 Astronomy Now

The afterglow from the distant neutron star merger detected last August has continued to brighten — much to the surprise of astrophysicists studying the aftermath of the massive collision that took place about 138 million light-years away and sent gravitational waves rippling through the Universe.

First light detected from violent neutron star collision

16 October 2017 Astronomy Now

For the first time, scientists have detected light tied to a gravitational-wave event, thanks to two merging neutron stars in the galaxy NGC 4993, located about 130 million light-years from Earth in the constellation Hydra.
