A more complete expansion for black hole ringdown waveforms

Black hole spectroscopy is the program of measuring how black holes "ring down" to infer their properties, just as we recognize a musical instrument by the sound it makes.

Quantum leap in precision sensing across technologies

Researchers at the Niels Bohr Institute have developed a tunable system that paves the way for more accurate sensing in a variety of technologies, including biomedical diagnostics.

Sound Signals in Computer Chips – Almost Without Signal Loss

Assistant Professor Xiang Xi and Professor Albert Schliesser at the Niels Bohr Institute have managed to get vibrations to travel around a membrane with almost no loss. In fact, so little loss that it is far better than…

Strong sails like the Vikings

On a wind-whipped day, June 14, 2025, in Roskilde, members of the Strong group embarked on an adventure to learn the Viking tradition that is rooted in the land that hosts us.

Master defense by Matilde Garcia

On June 11, 2025 at 11:00 AM in room HB1 at the Niels Bohr Institute, Matilde Garcia will defend her master thesis supervised by Associate Professor Jose Maria Ezquiaga.

Zvi Bern receives the Niels Bohr Institute Medal of Honour, 2024

Zvi Bern is awarded the Niels Bohr Institute of Honour for his remarkable list of scientific achievements in theoretical physics. His association with the Niels Bohr Institute goes back more than 40 years.

A 1960s idea inspires NBI researchers to study hitherto inaccessible quantum states

Scientists have created a new way to study the highly volatile quantum states in superconducting vortices, whose existence has been known since the 1960s, but it has been very difficult to verify them directly, until…

All you wanted to know about black hole spectroscopy

Black holes vibrate, like stars, or guitar strings. The "ringdown" radiation emitted by oscillating black holes has great scientific potential.
