The Institute for Fundamental Physics of the Universe (IFPU) is a joint initiative of the International School for Advanced Studies (SISSA), the Abdus Salam International Centre for Theoretical Physics (ICTP), the National Institute for Astrophysics (INAF) and the National Institute for Nuclear Physics (INFN). The institute aims at hosting and promoting a vigorous and innovative multi-disciplinary research program focused on investigating the fundamental laws of Nature under a Cosmological and Astrophysical perspective.

Motivations of the Workshop

One of the most important open issues of Cosmology and of the entire Physics, concerns the actual nature of the Dark Matter. Namely, of that elusive substance that comprises the 84% of the entire matter content of the Universe without emitting any radiation at the rate at which the elementary particles of the Standard Model do.
At SISSA there is a long tradition of investigating such mystery by means of the observational properties of this dark component surrounding every galaxy with a dark halo. The results obtained, supported also by independent investigations, point, for the Dark Matter Phenomenon, towards the need of a change of the 30 years old Paradigm according to which the Scenario for DM has to be the simplest, the most elegant and the most theoretically favored and expected. It is well known that while the latter lead us to the collisionless LCDM scenario, the inferred distribution of DM in galaxies of different mass and morphology points to a much more complex and unpredicted one.
In this Workshop we will recap on how the astrophysics of galaxies has become a Portal to the nature of dark matter and, accordingly, we will plan future strategies of investigation able to exploit such an opportunity.

Following the Workshop

In addition to the participants above listed:

  • People associated at IPFU can follow the talks of the Workshop in presence at Via Beirut 2. See the program.
  • People from outside Trieste can ask for the Zoom link to the talks by contacting the Scientific Secretary.


The institute is located in the Miramare campus at Via Beirut 2, Trieste, Italy. It can be easily reached from Trieste train station by bus number 6. Some accomodation place are at walking distance from the institute, others along the N 6 bus route Trieste-Miramare.

Bus Line Number 6

This line connects IFPU BUS Station (Centro Fisica ICTP Bus Station) with Adriatico Guest house (Final Stop at Grignano) and, in the opposite direction to Trieste Stazione dei treni.
