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.

1. Measurement of extragalactic magnetic fields by TeV gamma ray telescopes ( 40 min + discussion)
After a short discussion of different ways of measurement of magnetic fields in the Universe, I will explain
a method of measurement of extragalactic magnetic fields in observations of TeV gamma-rays from distant
blazars. Multi-TeV gamma-rays interact with the infrared photon background producing secondary
electrons and positrons, which can be just slightly deflected by extragalactic magnetic fields before they
emit secondary gamma-rays via inverse Compton scattering of cosmic microwave background photons.
Secondary gamma-rays emitted toward an observer on the Earth can be detected as extended emission
around initially point source. Energy dependent angular size of extended emission is related to the value of
extragalactic magnetic field along the line of sight. Small magnetic fields B < 1e-12 G in the voids of the
large scale structure can be measured (or ruled out) in this way.
