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.

Hunting for traces of axions and axion-like particles with high-energy astrophysical observations
Axions and axion-like particles are hypothetical particles that are predicted in numerous extensions of the Standard Model. In addition to being a candidate for cold dark matter, the axion would also naturally explain the non-observation of the electric dipole moment of the neutron. These particles could be detected through their feeble interaction with photons in the presence of electromagnetic fields.
In this talk, I will review how traces of this interaction could manifest themselves in astrophysical observations from X-ray to very high gamma-ray energies. In particular, spectra of bright active galactic nuclei have turned out to be a powerful tool in this endeavor, providing the most stringent bounds to date on the photon coupling for very light axion-like particles. Moreover, core-collapse supernovae have been identified as promising search targets. With several new observatories coming online in the 2020s, astrophysical observations will provide new opportunities for a discovery of these particles complementary to dedicated future laboratory searches.
