Eccentric Black Hole Mergers in Globular Clusters

This simulation shows a binary-binary encounter involving four black holes, which can occur at the cores of dense stellar systems such as gloublar clusters. Such encounters can lead to long-lived “resonating” interactions, through which many temporary binary systems are created. By incorporating a more accurate description of Einstein’s gravity in the equations of motion, the formation

What is LIGO?

CIERA Director and Northwestern LIGO group lead Vicky Kalogera talks about the different types of waves astronomers have used throughout history to study the Universe. Now, we are in the age of “multi-messenger” astronomy. This means that different types of waves from the same cosmic event can be studied.
