AstroNu
The AstroNu team aims at unveiling the physics of fascinating weakly interacting elementary particles, such as the neutrino, and explores the role of these particles and weak interactions in astrophysical sources, in the synthesis of new elements, and in the Early Universe.
The AstroNu group also adopts particles (neutrinos, photons and gravitational waves) as probes of the inner workings of astrophysical transients.
AstroNu is a research group at the Niels Bohr Institute, University of Copenhagen. We are affiliated with the Niels Bohr International Academy and DARK and work at the intersection between astrophysics and fundamental physics.

Our activities are supported by the European Research Council, the University of Copenhagen, the Villum Foundation, the Carlsberg Foundation, the Danmarks Frie Forskningsfond, and the Deutsche Forschungsgemeinschaft.
The AstroNu group is actively engaged in enhancing diversity at the Niels Bohr Institute. We firmly believe that a diverse and inclusive scientific environment is beneficial to our research work.

The AstroNu group aims at addressing the following questions:
- Which is the role of weakly interacting particles and weak interactions in dense environments, such as core-collapse supernovae, neutron-star mergers, and the early universe?
- What is the impact of neutrino flavor conversion on the stellar dynamics and formation of elements in the Universe?
- How are particles produced in cosmic accelerators? Under which conditions could efficient particle acceleration occur in astrophysical sources?
- What are the detectable imprints of the source physics carried by cosmic messengers (neutrinos, photons and gravitational waves)?
- How can we learn about non-standard physics through astrophysical sources?
- What are the chances of detecting cosmic messengers with existing and upcoming facilities?
