Chameleon pulsar baffles astronomers

A pulsar that is able, without warning, to dramatically change the way in which it shines has been identified by an international team of astronomers.

Energy loss gives unexpected insights in evolution of quasar

An international team of astrophysicists observed for the first time that the jet of a quasar is less powerful on long radio wavelengths than earlier predicted. This discovery gives new insights in the evolution of quasar ...

LOFAR radio telescope reveals secrets of solar storms

An international team of scientists led by a researcher from Trinity College Dublin and University of Helsinki announced a major discovery on the very nature of solar storms in the journal Nature Astronomy.

Student discovers slowest ever pulsar star

An approximately 14 million year old pulsar star that is the "slowest-spinning" of its kind ever identified has been discovered by a Ph.D. student from The University of Manchester.

Swirling electrons in the whirlpool galaxy

The whirlpool galaxy Messier 51 (M51) is seen from a distance of approximately 30 million light years. This galaxy appears almost face-on and displays a beautiful system of spiral arms.

Finger on the pulse of the pulsars

(PhysOrg.com) -- An international team of astronomers including German scientists has succeeded in recording the most sensitive observations to date of pulsars at low frequency. The measurement was undertaken with the European ...

LOFAR takes the pulse of the radio sky

(PhysOrg.com) -- A powerful new telescope is allowing an international team led by University of Manchester scientists to have their “best-ever look” at pulsars – rapidly rotating neutron stars created when ...

LOFAR

LOFAR is the Low Frequency Array for radio astronomy, built by the Netherlands astronomical foundation ASTRON and operated by ASTRON's radio observatory.

LOFAR will be the largest connected radio telescope ever built,[citation needed] using a new concept based on a vast array of omni-directional antennas. The project is based on an interferometric array of radio telescopes using about 20,000 small antennas and at least 48 larger stations. 40 of these stations are distributed across the Netherlands, five stations in Germany, and one each in Great Britain, France and Sweden. Further stations may also be built in other European countries. The total effective collecting area is up to approximately 300,000 square meter, depending on frequency and antenna configuration. The data processing is performed by a Blue Gene/P supercomputer situated in the Netherlands at the University of Groningen.
