Sky survey reveals newborn jets in distant galaxies

Astronomers using data from the ongoing VLA Sky Survey (VLASS) have found a number of distant galaxies with supermassive black holes at their cores that have launched powerful, radio-emitting jets of material within the past ...

A 4G network on the moon is bad news for radio astronomy

As you drive down the road leading to Jodrell Bank Observatory, a sign asks visitors to turn off their mobile phones, stating that the Lovell telescope is so powerful it could detect a phone signal on Mars.

SLAC invention could make particle accelerators 10 times smaller

Particle accelerators generate high-energy beams of electrons, protons and ions for a wide range of applications, including particle colliders that shed light on nature's subatomic components, X-ray lasers that film atoms ...

Apertif images yield first scientific results

Using Apertif (APERture Tile In Focus), searching at a radio frequency of 1.4 GHz, researchers have found an intra-hour variable (IHV) source, described in the paper "Extreme intra-hour variability of the radio source J1402+5347 ...

Very high energy gamma-ray emission from a radio galaxy

Giant elliptical galaxies, the oldest known large galactic structures in the universe, have no spiral arms and little or no current star formation activity, but their central supermassive black holes are often active galactic ...

New material acts as an efficient frequency multiplier

Higher frequencies mean faster data transfer and more powerful processors—the formula that has been driving the IT industry for years. Technically, however, it is anything but easy to keep increasing clock rates and radio ...
