Research

Despite its small size, the group is active in all aspects in very-high energy gamma-ray astronomy, an emerging new field of science.

This includes development of novel instruments, operation and data taking with current instruments and data analysis and interpretation of latest results and putting them in context with measurements at other wavelengths.

Planets contain more water than thought

Magma ocean planet in dark space.

Most of a planet’s water is generally not on its surface but hidden deep in its interior. This affects the potential habitability of distant worlds, as shown by model calculations of researchers at ETH Zurich and Princeton University.

Two projects launched to connect error-corrected qubits

ETH Zurich is participating in two quantum computing projects that are being financed by IARPA, the US research funding agency, with up to 40 million dollars. Both projects aim to connect two error-corrected qubits with one another and thus lay the foundation for future quantum computers.

A contradiction at the heart of physics

Quantum mechanics describes the forces that hold the world together on the smallest scale. The theory of relativity explains the world at the cosmic level. The two seem incompatible – and a unifying theory is nowhere in sight.

A space telescope, please – but a sustainable one, if possible

Daniel Angerhausen

Daniel Angerhausen believes that fundamental research is essential, especially in the current crisis. Still, he wonders if we shouldn’t extend the idea of sustainability into the infinite reaches of outer space.

Researchers at ETH have developed a technique to cool several nanoparticles simultaneously to temperatures of just a few thousandths of a degree above absolute zero. This new method can be used to study quantum effects of several nanoparticles and to build highly sensitive sensors.

Education

While PhD students get deep insight on all aspects, from detector design to data interpretations, the education we are responsible for Batchelor and Master Students covers two main topics:

a) Two-semester course on AstroParticle-Physics, concentrating mainly on Cosmic Ray Physics, Neutrino Astronomy, High-Energy Astronomy and Dark Matter

b) Physics Laboratory Courses for non-physicsics
