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 largest explosions that we have observed in the Universe are from the so called gamma-ray bursts (GRBs). They are emitted in connection with the collapse of the central regions of massive stellar remnants, into either a blackhole or a magnetar, and a subsequent development of an ultra-relativistic jetted outflow. Since GRBs typically occur at very large distances they have great potential for cosmology and the study of the first generation stars. However, the necessary basic understanding of the processes leading to the observed gamma-ray emission is still incomplete. I will present the development of the current paradigm which includes emission from the region in which the relativistic jet becomes optically thin, the photosphere. In particular, I will review recent developments in our understanding of the properties of a relativistic photosphere and the diagnostic tools that are emerging from this study.
