Capturing free-space optical light for high-speed Wi-Fi

Visible and infrared light can carry more data than radio waves, but has always been confined to a hard-wired, fiber-optic cable. Working with Facebook's Connectivity Lab, a Duke research team has now made a major advance ...

Observations inspect radio emission from two magnetars

Using the Australia Telescope Compact Array (ATCA) and the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have conducted a study of two magnetars known as PSR J1622−4950 and 1E 1547.0−5408. Results of ...

GECAM team reports first detection of gamma-ray transients

In the early morning of Jan. 20 (Beijing Time), the Gravitational Wave High-Energy Electromagnetic Counterpart All-sky Monitor (GECAM or Huairou-1) team reported their first detection of a gamma-ray transient (GRB 210119A) ...

A new way to look for gravitational waves

In a paper published today in Physical Review Letters, Valerie Domcke of CERN and Camilo Garcia-Cely of DESY report on a new technique to search for gravitational waves—the ripples in the fabric of spacetime that were first ...
