WATCHDOG

Whole-sky Alberta Time-resolved Comprehensive black-Hole Database Of the Galaxy

Version 2.0

Welcome to the WATCHDOG Database!

WATCHDOG is a comprehensive database of black hole (and black hole candidate) X-ray binary (BHXB) activity in the Galaxy. It makes use of 7 individual all-sky, scanning survey, and narrow-field X-ray instruments on board:
• the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL Galactic Bulge
Monitoring Program
),
• Monitor of All-Sky X-ray Image (MAXI GSC),
• Rossi X-ray Timing Explorer (ASM, PCA & HEXTE pointed obs., PCA Galactic Bulge
Scan
), and
• Swift (BAT Transient Monitor)
telescopes.

Built to operate as an interactive online interface, WATCHDOG is meant to act as an multi-purpose, easy to use resource for the widespread XRB community. Our overall goals is for WATCHDOG to not only replaces decade-old catalogs, but also provide a resource that enables us to probe XRB outburst behaviour over decades of energy (2-100 keV) and time. For detailed information on the algorithms behind the array of features available in WATCHDOG, see the first results paper: Tetarenko et al. 2016, ApJS, 222, 15.

Note: If you are interested in X-ray sources located in globular clusters, we provide a convienient link to a catalogue of globular cluster sources, created and maintained by Arash Bahramian, in the appropriate tag above.

THIS SITE IS CURRENTLY UNTER CONSTRUCTION. THUS, NOT ALL FEATURES MAY BE AVAILABLE AT THIS TIME. WE APOLOGIZE FOR THE INCONVENIENCE.
