Capability for Encoding Gravitational-wave Sky Localizations with the Multi Order Coverage Data Structure: Present and Future Developments

Résumé

The IVOA standard Multi-Order Coverage map (MOC) is a data structure based on the HEALPix tessellation of the sky, and it can be used to encode the area within a given probability level contour of a gravitational-wave (credible region) sky localization. MOC encoded credible regions can be created, visualised and manipulated using Aladin Desktop. The Aladin Desktop enables the users to compare the MOC regions with existing electromagnetic surveys and to query the VizieR database. These tasks can also be performed via Python using the astropy affiliated package, mocpy, which are efficiently displayed in javascript applications with Aladin Lite, and integrated within Jupyter notebooks through the ipyaladin widgets.

The paper also describes an enhanced MOC structure which allows us to include temporal information about gravitational-wave events. This data structure, the Space and Time MOC (ST–MOC), provides us with an effective way to develop new multi-messenger data analysis tools which will be necessary when the third-generation interferometric gravitational wave observatories, such as the Einstein Telescope (ET), will begin operation.
