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.

Constraints on cosmic strings from gravitational waves, diffuse gamma-ray background and dark matter
Cosmic strings are stable topological defect solutions of field theories which may have formed during phase transitions in the early Universe. The detection or non-detection of these relics can constrain the physics of very high energies and extensions of the Standard Model. Under the Nambu-Goto approximation, which assumes that cosmic strings are one-dimensional, cosmic strings emit only gravitational waves which we can hope to detect in GW detectors in the near future.
In this seminar, I will give a short introduction to cosmic strings before reviewing the current bounds on the string tension $G\mu$ coming from ongoing and future GW detectors, both from the stochastic background and burst events. Then I propose to go beyond the Nambu-Goto approximation, including the emission of massive particles and the dynamics of superconducting strings. I present the consequences of these effects on the observational signatures of cosmic strings, in particular on the gravitational wave stochastic background, gamma-ray background and dark matter abundance.
