LIGO Does It Again: A Second Robust Binary Black Hole Coalescence Observed

June 16, 2016

The two LIGO gravitational wave detectors in Hanford Washington and Livingston Louisiana have caught a second robust signal from two black holes in their final orbits and then their coalescence into a single black hole. This event, dubbed GW151226, was seen on December 26th at 03:38:53 (in Universal Coordinated Time, also known as Greenwich Mean Time), near the end of LIGO's first observing period ("O1"), and was immediately nicknamed "the Boxing Day event".


First search on the advanced-generation LIGO detector data

March 09, 2016

The first E@h search on the advanced-generation LIGO detector data (O1) has started ! We are searching the sky for gravitational wave signals with frequencies between 20 Hz and 100 Hz. We have packed two searches in a single application: one for standard ever-lasting continuous gravitational waves and the other for continuous signals lasting only some days.


Discovery of 13 new gamma-ray pulsars by Einstein@Home volunteers

February 22, 2016

The 4th Einstein@Home survey for gamma-ray pulsars, or "FGRP4", using data from NASA's Fermi Gamma-ray Space Telescope is currently nearing completion. This survey has incorporated many new advances that we learned during our previous investigation of blind search methods. In addition, we were able to utilize the superior "Pass 8" data from the Fermi-LAT team, and search in longer data sets than ever before. In combination, these improvements led to FGRP4 being our most sensitive survey to date.
