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.


Zwicky Transient Facility (ZTF)

This page provides a default interface to the ZTF. The table lists ZTF records in descending order by jd. Use the filters on the right to narrow down the results to areas of interest. When the results look good, add ?format=json to the URL. You can then access the URL to retrieve the full data and use it in your scripts. You can access an alert's previous alerts by visiting /<sid>/ where sid is the value of the sid key in the JSON view or by clicking the sid link in the table.
