ASASSN

ASASSN, an acronym for All-Sky Automated Survey for Supernovae, is a network of ground-based telescopes designed to detect and study transient astronomical events, particularly supernovae. The project was initiated in 2014 by Benjamin J. Shappee and Kris Stanek at Ohio State University. ASASSN employs a fleet of small, robotic telescopes equipped with wide-field cameras, strategically placed at various locations around the world to provide continuous coverage of the entire sky.

The primary goal of ASASSN is to discover and monitor supernovae and other transient events in real-time. The network's automated system allows for the rapid identification and classification of these events, enabling astronomers to study them shortly after their discovery. ASASSN has contributed significantly to the field of time-domain astronomy, providing valuable data on the dynamics and properties of supernovae and other transient phenomena.

ASASSN has discovered thousands of supernovae and other transient events since its inception. The project has also played a crucial role in the study of other astronomical phenomena, such as gamma-ray bursts, tidal disruption events, and variable stars. The data collected by ASASSN is made publicly available, facilitating further research and collaboration among astronomers worldwide.

The success of ASASSN can be attributed to its innovative use of small, robotic telescopes and its automated data processing pipeline. The network's continuous monitoring of the sky and rapid response to transient events have made it a valuable tool for astronomers studying the dynamic universe.
