Multi-epoch observations refer to the collection of data over multiple time intervals or epochs in astronomy or other scientific fields. By observing the same object or phenomenon repeatedly over time, researchers can track changes or variations that occur over different time scales. This type of observational approach is particularly valuable for studying dynamic or evolving systems, such as variable stars, active galactic nuclei, or transient events like supernovae and gamma-ray bursts. Multi-epoch observations can provide insights into the underlying mechanisms driving these changes and help scientists better understand the processes at work in the universe.
