The E-ROAD is an initiative of the International Astronomical Union, the…

University Lecturer Ahab Bdaiwi:

The success of Dutch radio astronomy in the last century was largely due to Leiden astronomer Jan Hendrik Oort. He made astute use of circumstances in the post-war period. Historian Astrid Elbers' research focuses on this golden period.

You can make some astounding images using just a box with a hole. Inspired by the celebration of Leiden as the European City of Science, Professor Matthew Kenworthy left several pinhole cameras across the Observatory over the course of 2021. This is how the simplest devices may uncover the greatest…

In this thesis we push the boundaries of high-resolution imaging at radio frequencies between 100 and 200 MHz. Using the International LOFAR Telescope that spans across Europe we achieve sub-arcsecond angular resolution.

For centuries, astronomers have studied the universe by collecting light signals. Since 2015, the confirmation of an important prediction of Einstein allows us to explore the universe in a new way: through gravitational wave radiation. Astronomy PhD candidate Valeriya Korol proposes to use these gravitational…
