In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Signatures of magnetic fields in the young galaxies
Local galaxies are in a state of "energy equipartition", meaning kinetic, thermal, and magnetic energy density being comparable. Recent studies of galaxy formation suggest that the small-scale dynamo can produce strong magnetic fields by randomly stretching, twisting, and folding the field lines already in primordial minihalos. Due to the large growth rate of the dynamo, the equipartition field strength is reached within only a few Myrs. A signature of magnetic fields is synchrotron emission from cosmic ray electrons spiralling around the field lines. With the strength of magnetic fields being high from early on, we expect significant non-thermal radio emission also from distant galaxies. We use a semi-anlytical galaxy model to determine the synchrotron flux as a function of redshift while assuming energy equipartition. We find that synchrotron emission can be detected up to cosmological redshifts with current and future radio telescopes. This provides an observational test for the evolution of galactic magnetic fields.
