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.

Understanding the nuclear physics of neutron stars with astrophysics
(University of Turku)
Neutron stars are one of the most dense objects in the Universe. However, the exact description of the equation of state (EoS) of the cold ultra-dense matter inside them is still a mystery. In my talk, I will show how we can measure the size of some neutron stars using astrophysical observations of X-ray bursts that are produced by thermonuclear runaways in the uppermost layers of the star. Similar measurements can also be obtained by using pulse profiles from millisecond X-ray pulsars. There, the pulse profile itself encodes information from the curved spacetime and can then be used to constrain the compactness of the source. By measuring the size and compactness of neutron stars, we can then set constraints on the nuclear physics of the interiors and ultimately on the EoS of the cold dense matter.
