Black hole mergers, cataloged

Posted Leave a comment

Ok, I have to give up remembering all merger event names…. In the LVK collaboration we just published the O3a Gravitational Wave Transient Catalog. The verdict: 39 confirmed mergers between April 1st and October 1st 2019. The plot above gives a nice overview of the component and final mass distributions. Another impressive number: about 1.5 […]

In an announcement that National Science Board (NSB) chair Dr. Dan Arvizu called “one of the coolest discoveries in decades“, the LIGO and VIRGO Scientific Collaborations announced the observation of gravitational waves from two colliding black holes. The picture above was featured on APOD. Read more on it in the NY times, or directly from the paper.
