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.

Imre Bartos: "The black hole that should not exist, and other recent surprises in gravitational wave astrophysics"
Since their first discovery in 2015, gravitational-wave and multi-messenger observations yielded several "surprises." The LIGO and Virgo observatories detected more and heavier black holes than anticipated; multi-messenger emission from neutron star merger GW170817 showed structured high-energy outflow; and earlier month, LIGO announced the discovery of a particularly heavy black hole that could have not come from stellar core collapse. In the next five years, LIGO's expected detection rate is set to increase twentyfold, to roughly one event every hour, promising many more surprises and new questions we can address. I will discuss several of the new interesting directions in gravitational-wave and multi-messenger observations that began only recently and promise to substantially enrich the field in the next five years.
