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.

The H.E.S.S. view on the Very High Energy Universe.

In the last 15 years, ground based Atmospheric Cherenkov Telescopes have opened
a new astronomical window, at the upper part of the electromagnetic spectrum, and discovered
a rich zoo of both galactic and extra galactic very high energy gamma-ray emitters, belonging to the classes
of pulsar wind nebulae (PWN), supernova remnants (SNR), active galactic nuclei (AGN), y ray binaries
and even more exotic ones.
This major breakthrough was made available by the advent of mature, third generation instruments, such as
H.E.S.S., MAGIC and VERITAS. The H.E.S.S. array of telescopes, located in Nambia and inaugurated in 2003 with
four telescopes, was completed in 2012 by the addition of a fifth, giant telescope of 28 meter diameter, which is
currently the largest in the world. H.E.S.S. was awarded the Descartes Prize for 2006 and Rossi Prize in 2010
in recognition of its numerous discoveries, and took an important part in the current emergence of multi-messenger,
multi-wavength astronomy that is currently revolutionizing our view on the High Energy Universe.
After a quick description of the Atmospheric Cherenkov technique, I will present a summary of the latest H.E.S.S. results,
describing the most interesting new observations and their physical interpretation. I will conclude with the latest and
upcoming upgrades of H.E.S.S. and the future science prospects for the experiment as well as for the field of ground based
gamma-ray astronomy in general.
