Welcome to the FLASHES2.0!

This is the FLexible Alert System for High Energy Sources. FLASHES is a monitoring and analyses tool for x-ray sources in space. It provides lightcurve data from the Monitor of All-sky X-ray image (MAXI), the Burst Array Telescope (BAT) of Swift, and the Gamma-Ray Burst Monitor (GBM) on Fermi are automatically downloaded, processed and analysed every day. For each source in the FLASHES source catalog, a relevance is calculated. If a worth-mentioning event is happening, a high relevance value (close to 1) is assigned. If nothing happens, a low relevance value (around 0) is assigned.

The sources in the FLASHES catalogue are departed into several categories. The categorization is based on HEASARC. Each category has an overview table that can be assessed in the frontend. The tables provide an overview of the measurements for each source. The four most important tables are shown below. Additionally, each source has a detail page showing all available details and a dashboard for the timeseries.

Use the navigation bars above to explore the complete source catalogue, select tags, and learn more about FLASHES2.0. Enjoy your stay!

The FLASHES2.0 Open β

FLASHES2.0 is currently in open beta. This means that not all features are fully implemented and bugs may still occur. Currently, the following features are available:

• Browse the whole FLASHES2.0 source catalog
• Filter sources based on automated tagging
• Find first details of every source (more details to come!)
• View daily updated flux data and (if available) hardness information on dedicated dashboards
• Download interesting datasets directly from the dashboards

More features are comming soon! Here is a short overview of planned features:

• Relevance evaluation of each source based on their past to detect interesting features
• Alerting and advertizing of relevant sources in the tables, on the main page and via Email
• More detailed source information including relevances
• Common units for dashboards (MJD and mCrab)
• Build dashboards for an indivdual selection of sources without creating an account
• A map of the sky showing all sources for a better visual overview
