Research examines emission from the blazar TXS 0506+056

Using the Very Energetic Radiation Imaging Telescope Array System (VERITAS), an international team of astronomers has conducted long-term observations of a gamma-ray blazar known as TXS 0506+056. Results of the observational ...

Graphene may open the gate to future terahertz technologies

Nestled between radio waves and infrared light is the terahertz (THz) portion of the electromagnetic spectrum. By adding a nanoscale bit of graphene, researchers have found a better way to tune radiation for a THz transmitter.

'Nanoresonators' might improve cell phone performance

(Phys.org)—Researchers have learned how to mass produce tiny mechanical devices that could help cell phone users avoid the nuisance of dropped calls and slow downloads. The devices are designed to ease congestion over the ...

Looking at Jupiter's radio frequencies

In the visible spectrum, Jupiter is a bright, star-like point in the night sky. Viewing it with the naked eye, it would be easy to confuse it with a star except for the fact that it doesn't twinkle. At radio frequencies ...

'Spectrum crunch' may slow US mobile revolution

The United States is bracing for a data crunch from the surging use of smartphones, tablets and other mobile devices as the explosion of Internet-ready devices eats up the radio spectrum allocated for mobile broadband.

A spiral galaxy with a secret

(Phys.org)—The NASA/ESA Hubble Space Telescope – with a little help from an amateur astronomer – has produced one of the best views yet of nearby spiral galaxy Messier 106. Located a little over 20 million light-years ...
