A starry sky made of more than 25,000 supermassive black holes
An international team of astronomers has produced the largest and sharpest map of the sky at ultra-low radio frequencies, using the Low Frequency Array (LOFAR) radio telescope. The map published in the journal Astronomy & Astrophysics reveals more than 25,000 active supermassive black holes in distant galaxies.
ASTRON reveals life cycle of supermassive black hole
For the first time LOFAR and WSRT-Apertif have been used together to measure the life cycle of supermassive black holes emitting radio waves.
First direct detection of a brown dwarf with a radio telescope
Astronomers at ASTRON have discovered a brown dwarf with LOFAR. The discovery of the object dubbed Elegast, opens up a new path that uses radio telescopes to discover faint objects that are close-cousins of Jupiter-like exoplanets.
Simultaneous optical and radio observations of Perseids
From today (August 11th) up until Friday the yearly Perseids meteor shower will have its peak. This phenomenon is not only interesting for amateur astronomers, professional astronomers will be observing them as well.
What we look forward to in LOFAR 2.0: Live warning system to study solar eruptions
The Sun’s activity appears not only in the well-known 11-year Sunspot cycle, but also in short duration eruptions as flares and coronal mass ejections (CMEs).
What we look forward to in LOFAR 2.0: Habitability of alien worlds
The Earth receives its life-sustaining energy from Sunlight, but “explosions” on the Sun can also be life-threatening. Explosions on the Sun’s surface, called flares, can spew out large masses of plasma and harmful radiation towards the planets.
What we look forward to in LOFAR 2.0: Cranking up LOFAR’s robustness
In order to receive radio signals from across the Universe, LOFAR needs to be very sensitive. The downside of that sensitivity is susceptibility to radio interference: other sources that produce radio signals that LOFAR detects, but does not want to measure.
What we look forward to in LOFAR 2.0: LOFAR expands to Italy
In 2018, Italy officially joined the International LOFAR Telescope (ILT) and in the near future the LOFAR station in Italy will become operational.
What we look forward to in LOFAR 2.0: A new specification and scheduling system
In 2021, ASTRON will deliver TMSS (Telescope Manager Specification System), which is a brand-new platform for the specification, administration, and scheduling of LOFAR observations.
What we look forward to in LOFAR 2.0: High-precision clock to all Dutch stations
In the LOFAR radio telescope, the observation data is synchronized over time for accurate processing of the received signals. Until now, the telescope uses GPS techniques to synchronize the observation data, achieving an accuracy between 1 ns and 10 ns.
What we look forward to in LOFAR 2.0: Detecting SMBH particles
Supermassive black holes can leave a trail of energetic particles that astronomers are able to detect using radio telescopes.
What we look forward to in LOFAR 2.0: A brain transplant for LOFAR
If the antennae of LOFAR are the senses of the radio telescope, then the central correlator is its brain. It is the place where all the data streams come together and are converted into astronomy data.
