NSF Panel for First Cosmic Event seen in Gravitational Waves and Light

LIGO – Virgo discovery marks first cosmic event observed in both gravitational waves and light. Announcement made at the National Press Club, Washington, DC. Panel with representatives from various telescopes, begins at 51:21 (Please note that Marica Branchesi’s institutional affiliation is incorrectly indicated in the video.

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

Radio Rebound Powered by Jets from Gamma-Ray Burst

Astronomers using ALMA studied a cataclysmic stellar explosion known as a gamma-ray burst, or GRB, and found its enduring “afterglow.” The rebound, or reverse shock, triggered by the GRB’s powerful jets slamming into surrounding debris, lasted thousands of times longer than expected. These observations provide fresh insights into the physics of GRBs, one of the

What is LIGO?

Interview

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.
