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.

Infrared spectrum of H3+ from the laboratory to the Galactic center
(The University of Chicago)
Protonated molecular hydrogen, H3+, is the simplest polyatomic molecule discovered by J.J. Thomson exactly 100 years ago. It is the most abundant molecular ion in hydrogen dominated plasmas and plays the central role in the formation of interstellar molecules. The infrared spectrum of H3+ discovered in the laboratory1 has led to its detection in 1996 toward two young stars deeply embedded in their natal dense clouds.2 Although it took many years to detect the first signal, once detected, H3+, has been observed everywhere. It was detected not only in dense clouds (n ~ 104 cm-3) as theoretically predicted but, surprisingly, also in diffuse clouds (n ~ 102 cm-3) where the abundant electrons were thought to destroy H3+. The most amazing discovery has been the very high abundance of H3+ in the Central Molecular Zone (CMZ), the region with radius ~ 200 pc, of the Galactic center. This has revealed a new category of gas with high temperature (~ 250 K) and low density (< 100 cm-3) with a high volume filling factor.3 Recent extension of this observation to wider regions of the CMZ4 will be discussed.
