The Steward Alerts for Science System (SASSy) provides access to various alerts and cross-correlation with catalogs. We provide support for queries to alerts and database(s) sourced from the Galaxy List for the Advanced Detector Era (GLADE), the Gravitational Wave Galaxy Catalog (GWGC), (ad-hoc) alerts from the Laser Interferometer Gravitational-Wave Observatory (LIGO), the Transient Name Server (TNS) and the Zwicky Transient Facility (ZTF). Further information is available in the (help) and (api) sections.

These pages are adapted from the code from LCOGT (Las Cumbres Observatory Global Telescope) which delivers the MARS (Make Alerts Really Simple) website.
