A conference dedicated to the study of cosmic magnetism using probes of the Cosmic Microwave Background, emissions from Blazars, and theory with cosmological simulations.
Scientific questions:
- whate are the observable features of primordial magnetism?
- how does primordial magnetism affect structure formation?
- how can we use Blazar to constrain cosmic magnetism?

All conference partecipants are kindly asked to adhere to our Code of Conduct (based on the 2015 London Code of Conduct), and to take notice of our support to the Free Circulation of Scientists.
The SOC firmly condemns the Russia war against Ukraine and agrees with the view expressed by the European Research Council on 8 March 2022:
“We, the ERC Scientific Council, condemn the Russian attack on Ukraine. We express our strongest support for Ukraine and its scientific community.
We applaud those, including many courageous Russian scientists, who have spoken out against this war. Many European research institutions are offering to host researchers from Ukraine who have had to flee their country. We encourage this and other support initiatives - they all make a difference.
We are reminded at this time that the scientific community must stand together and show solidarity.”

Scientific Rationale
Scientific Rationale
The origin of cosmic magnetism is one of the most fascinating topics in astrophysics and cosmology.
Both a primordial or an astrophysical origin are consistent with current observations, which include upper limits on primordial magnetic seeds from the cosmic microwave background (CMB), detection of magnetic fields in large scales structures, and lower limits on the magnetisation of voids inferred by TeV blazars observations (difficult to explain by
fully astrophysical seed magnetic fields).
Cosmic magnetic fields with a comoving amplitude from 1 nG and 1e-7 nG fit this interesting observational window, which is expected to squeeze in the next decade.
This new conference comprises different technical and theoretical expertises in a unique way:
- primordial magnetic seeding mechanisms and the extraction of new limits on a stochastic background of primordial magnetic fields by the precise measurements of CMB anisotropies from Planck and future experiments
- the observation and modelling of TeV blazars data from the MAGIC telescopes, and in the future with the CTA.
- the study of magnetism with state of the art cosmological simulations, in which magnetic seeding mechanisms are coupled with a model for the evolution of the cosmic web and of galaxies.
The whole is greater than the sum of its parts, and the potentiality of this community does not simply rely on the sum of the different expertises present at this conference but rather in pursuing a truly joint approach to the study of cosmic magnetism across a wide range of redshifts and scales. This aspect is crucial to make potentially transformative advances in this field, such as discriminating among different generation mechanisms in a scientifically soundful way with available data, and this conference aims at creating new powerful synergies in the community.
Venue
The workshop will be held at DAMSLAB in Piazzetta Pierpaolo Pasolini, in the historic centre of Bologna.

We will not tolerate harassment of participants in any form. Please follow these guidelines:
- Behave professionally. Harassment and sexist, racist, or exclusionary comments or jokes are not appropriate. Harassment includes sustained disruption of talks or other events, inappropriate physical contact, sexual attention or innuendo, deliberate intimidation, stalking, and photography or recording of an individual without consent. It also includes offensive comments related to gender, sexual orientation, disability, physical appearance, body size, race or religion.
- All communication should be appropriate for a professional audience including people of many different backgrounds. Sexual language and imagery is not appropriate.
- Be kind to others. Do not insult or put down other attendees.
Participants asked to stop any inappropriate behaviour are expected to comply immediately. Attendees violating these rules may be asked to leave the event at the sole discretion of the organisers without a refund of any charge.
Any participant who wishes to report a violation of this policy is asked to speak, in confidence, to the ombudsperson designated for our Conference.
