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.

Black holes are multifaceted objects that probe the strong-field nature of gravity and can be used to test fundamental physics. I will describe how black holes can be used to test our knowledge of gravity in the most violent possible scenario, involving collisions at close to the speed of light and the relation with Cosmic Censorship. In addition, I will discuss superradiant instabilities in astrophysical black holes, in the presence of light bosonic fields. This effect, together with precision measurements of the mass and spin of massive black holes, has been used to constrain axions and ultralight scalars, to derive bounds on light vector fields and on the mass of the graviton, as well as to put intrinsic bounds on magnetic fields near black holes and on the fraction of primordial black holes in dark matter. The theoretical potential of these phenomena as almost-model-independent smoking guns for beyond-Standard Model physics and modified gravity are presented.
