ACHTUNG! Indico Wartung mit Dienstunterbrechung am Donnerstag dem 16.12.2021 von 10:00 Uhr - 11:00 Uhr (CET). Bitte beenden Sie ihre Arbeit rechtzeitig um Datenverlusten vorzubeugen! ATTENTION! Indico Maintenance with downtime on Thu 16 Dec 2021, 10 - 11h CET. Please finish your work in time to prevent data loss!
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.

Dark Photon, CMB and radio data in our inhomogeneous universe
(Tel-Aviv and Weizmann, Israel)
The dark photon is a well-motivated extension of the Standard Model which can mix with the regular photon. Whenever the dark photon mass matches the photon plasma frequency, a resonant conversion between photons and dark photons is possible. These conversions can produce observable cosmological signatures, including distortions to the cosmic radiation background. In this talk, I will discuss a new analytic formalism for these conversions that can account for the inhomogeneous distribution of matter in our universe, leading to new limits on the mixing parameter of light dark photons using COBE/FIRAS measurement of the cosmic microwave background spectrum. I will also briefly describe how a simple dark sector can explain the longstanding ARCADE radio background excess through resonant conversions of dark photons.
