The astronomical research at ASTRON is closely aligned with the strengths of 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).
The universe is teeming with objects that exhibit drastic variations in brightness over time scale from milliseconds to years.
A core area of research for astronomers at ASTRON is the study of the formation and evolution of nearby galaxies.
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.
The LOFAR telescope is used to conduct wide and deep surveys with unprecedented resolution and sensitivity at low radio frequencies.
The Earth’s magnetic field shields us from the constant stream of charged particles emitted from the sun known as solar wind.
As the Universe evolves, gravity brings together hundreds, sometimes thousands of galaxies together to form galaxy clusters.
A prominent research theme at ASTRON involves the study of Cosmic Dawn (CD) and Epoch of Reionization (EoR) with LOFAR.
Pulsars are fast rotating neutron stars that emit narrow beams of electromagnetic radiation at highly regular intervals.
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.
