Black Hole Detectors Fulfill Moore’s Law
In 1965 the engineer and future Intel co-founder Gordon Moore famously noticed that the number of transistors on microchips has been exponentially growing for several years, and predicted their unstoppable increase would thenceforward drive computing. Now known as “Moore’s law,” this remarkable forecast has largely held ever since. Given the constant changes and advances in making microchips, a consistent trend of exponential growth seems nothing short of miraculous.
Six Gravitational-Wave Breakthroughs Scientists Can’t Wait to See
On May 24, the Laser Interferometer Gravitational-Wave Observatory (LIGO) will resume its hunt for gravitational waves—tiny, periodic variations in the curvature of space and time created by distant, violent cosmic events such as two colliding black holes. Some would call gravitational-wave scientists lucky, based on their field’s remarkable series of transformative discoveries occurring in less than a decade’s time.
Detecting and diagnosing terrestrial gravitational-wave mimics through feature learning
Abstract As engineered systems grow in complexity, there is an increasing need for automatic methods that can detect, diagnose, and even correct transient anomalies that inevitably arise and can be difficult or impossible to diagnose and fix manually.
Architectural optimization and feature learning for high-dimensional time series datasets
Abstract As our ability to sense increases, we are experiencing a transition from data-poor problems, in which the central issue is a lack of relevant data, to data-rich problems, in which the central issue is to identify a few relevant features in a sea of observations.
Where (Some of) Earth's Gold Came From
The first detection of a neutron-star collision took 60 years after Margaret Burbidge and colleagues realized that the heaviest elements in the universe must be created in violent cosmic explosions. Gravitational waves observed from the collision by LIGO and Virgo in 2017 led to a worldwide hunt for the cosmic flash produced by the neutron star debris. The findings elevated neutron stars to be leading candidates to create Burbidge’s elements.
A nearby neutron-star merger explains the actinide abundances in the early Solar System
Abstract A growing body of evidence indicates that binary neutron-star mergers are the primary origin of heavy elements produced exclusively through rapid neutron capture1,2,3,4 (the ‘r-process’). As neutron-star mergers occur infrequently, their deposition of radioactive isotopes into the pre-solar nebula could have been dominated by a few nearby events.
Multimessenger Astronomy
Dr Imre Bartos received his PhD from Columbia University, USA, where he is currently a research scientist. He studies extreme cosmic explosions related to the formation and evolution of black holes. He is a member of the LIGO Scientific Collaboration, which recently announced the discovery of gravitational waves, and an associate member of the IceCube Collaboration.

A new cosmic messenger - physicsworld.com
Taken from the January 2018 issue of Physics World The first observation of gravitational waves from two merging neutron stars that was recently made by the LIGO and Virgo detectors has – along with date from telescopes across the globe and in space – kicked off a new era in multimessenger astronomy. Imre Bartos describes this watershed moment, which crowned decades of research and will shape the future of observational astronomy It was almost over.

It was almost over. There was only one week to go before the Advanced LIGO and Virgo detectors would complete their observational run, and be shutdown for a year. Indeed, many of my colleagues from the LIGO–Virgo team were already on vacation, while I was awaiting relatives who were visiting. Then my phone buzzed. An automated text message, which read “ALERT FROM GWHEN | New event: G298048 | Check your email!” prompted me to rush to my computer, to look at the signal in a LIGO database.
