Open Catalog of Possible Tidal Disruption Events

This repository is a collection of tidal disruption event data, including metadata, light curves, and spectra. The catalog is displayed in tabular form on tde.space. Individual event data can be downloaded by navigating to the output repositories and downloading the .json file associated with a given event; however it might be easier to use the search function on the table displayed on tde.space to find the event you're looking for.

Contributing Data

If you have a historical archive of data that likely won't be updated, feel free to e-mail your data directly to me and we'll do the hard work of converting it to the standard format. However, if you are an active observer and will add data all the time, we prefer to have you fork the repository and update/add events that way. This also allows observers to keep event data "private" in their fork until they are ready to add it to the repository.

Format of Data Files

The data files are in JSON format. Below is an example datafile for 2002ap:
