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.

"Numerical relativity in the multi-messenger astrophysics era" by Vassilios Mewes (RIT)
The detection of gravitational waves emitted in binary black hole mergers by LIGO-VIRGO has opened a new window into the universe, and the simultaneous detection of the electromagnetic counterparts observed in the binary neutron star merger GW170817 has marked the beginning of multi-messenger astronomy. Numerical relativity, in the form of both vacuum and general relativistic (magneto)hydrodynamic simulations of these systems is an indispensable tool in correctly predicting both spacetime and matter field evolutions during these extremely energetic and luminous events. Of particular interest in multi-messenger astronomy is the evolution of the matter in the post-merger remnant following a binary neutron star or black hole neutron star merger, as well the gas dynamics in the late stages of supermassive binary black hole inspiral. I will present a novel framework for highly accurate numerical relativity in spherical/curvilinear coordinates within the Einstein Toolkit. I will describe our implementation of the vacuum BSSN equations in these coordinates, and describe its extension to the GRMHD equations. Azimuthal flows and angular momentum transport are more accurately modeled in spherical coordinates, which are less diffusive than Cartesian coordinates, as they are better adapted to the approximate symmetries of the problem. Combining spherical coordinates with traditional moving mesh refinement, this framework will also enable more accurate simulations of high mass ratio binary black holes, which are of great importance to LISA as well as third generation LIGO-VIRGO observations.
