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.

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?

There are several projects at the Bachelor, Master, and PhD level within our group. Please do not hesitate in contacting Prof. Irene Tamborra if you are interested or just want to learn more about any of these.

If you are interested in joining the AstroNu group as postdoctoral fellow, follow the announcements on Academic Jobs Online. You could also consider to apply for individual national and international fellowships. Please, get in touch with Prof. Irene Tamborra, if you like to discuss the latter option further.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Seminars and Meetings

  • Once a week we host an Astro Seminar on a broad range of topics of interest to particle astrophysics, astrophysics and cosmology. The seminars usually take place in Auditorium A on Mondays at 14:15.
  • Once every other week we host an informal astroparticle journal club, in which group members and visitors discuss recent research papers or other topics of interest. The journal club takes place on Thursdays at 12:30 in room Bk2.
  • Every other Tuesday at 13:15 at DARK we host an informal discussion on astrophysical transients.
