Astronomy

The astronomical research at ASTRON is closely aligned to our facilities LOFAR and WSRT-APERTIF and contributes to the development and definition of the scientific programme and capabilities of the next generation of major international facilities such as the Square Kilometre Array (SKA). Topics include the detection and characterisation of fast radio bursts, the evolution of gas and star formation in distant and nearby galaxies, the detection of radiation from the epoch of reionisation, testing theories of gravity and detecting gravitational waves with compact objects.

Gravitational lensing

Gravitational lensing is observed when light from a star or galaxy is deflected by the gravity of a massive object, typically a galaxy or cluster of galaxies.

Space Weather

The Earth’s magnetic field shields us from the constant stream of charged particles emitted from the sun known as solar wind.

Clusters

As the Universe evolves, gravity brings together hundreds, sometimes thousands of galaxies together to form galaxy clusters.

Low Frequency Surveys

The LOFAR telescope is used to conduct wide and deep surveys with unprecedented resolution and sensitivity at low radio frequencies.

Cosmology

A prominent research theme at ASTRON involves the study of Cosmic Dawn (CD) and Epoch of Reionization (EoR) with LOFAR.

Compact objects

Pulsars are fast rotating neutron stars that emit narrow beams of electromagnetic radiation at highly regular intervals.

Active Galactic Nuclei

At the center of most galaxies lies a supermassive black hole that swallows material and in the process produces the brightest radiation in the universe across multiple wavelengths.

Radio Transients

The universe is teeming with objects that exhibit drastic variations in brightness over time scale from milliseconds to years.

Nearby galaxies

A core area of research for astronomers at ASTRON is the study of the formation and evolution of nearby galaxies.

Astronomy Publications

Another great achievement by @ehtelescope! Our new director @astroTui was involved as well, as a member of the #EHT team.

Every year on 4 May at 8 pm, our Westerbork telescope goes into a special mourning position to commemorate those who have fought for our freedom. This video, made together with @kampwesterbork, shows the dishes moving into position. https://youtu.be/nZacArKU5Ow

Our 'holy grail' has been found again! The #Kootwijk dish, which stood at the origin of ASTRON, has been located at @museumdeelen! The dish, originally a #Würzburg-Riese German radar dish, was the second telescope ever to detect the #hydrogen line.

Issue 10 of @SKAO's Contact Magazine has been published, featuring 3 articles related to ASTRON: 1 about our new director @astroTui, 1 about @LOFAR's massive data release, and 1 by our own @tammojan about @LOFAR imaging radio emissions of meteor showers.
