Binary star system precisely timed with pulsar's gamma-rays

Pulsars are rapidly rotating compact remnants born in the explosions of massive stars. They can be observed through their lighthouse-like beams of radio waves and gamma-rays. Scientists at the Max Planck Institute for Gravitational ...

Bats are surprisingly fast decision makers

Bats are not as stereotyped when they hunt as previously believed. New research shows that these flying mammals are capable of making ultra-fast decisions about how to attack their prey - or maybe even call off the attack. ...

Fermi finds a 'transformer' pulsar

(Phys.org) —In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the ...

With a deadly embrace, 'spidery' pulsars consume their mates

(Phys.org) —Black widow spiders and their Australian cousins, known as redbacks, are notorious for their tainted love, expressed as an unsettling tendency to kill and devour their male partners. Astronomers have noted similar ...

Triple millisecond pulsar laboratory challenges theory

(Phys.org) —Millisecond pulsars are old neutron stars, which rotate several hundred times per second. They are often found in binary systems and their existence can be explained by mass transfer from a companion star. The ...

Detected radio bursts evidence of 'exotic phenomena'

The detection of four short bursts of radio waves, possibly arising from explosions billions of light years away, could be powerful tools to study our Universe, according to research published in Science.
