Post-starburst galaxies, also known as "E+A" or "K+A" galaxies, are a type of galaxy that show characteristics of having recently experienced a burst of star formation followed by a sudden cessation of that activity. This results in a population of relatively young stars coexisting with an old stellar population. These galaxies are often characterized by strong Balmer absorption lines and little to no ongoing star formation activity, as evidenced by the lack of emission lines typically associated with star-forming regions. Post-starburst galaxies are thought to represent a transitional phase in galaxy evolution, where the recent starburst may have been triggered by a merger or interaction with another galaxy, and the cessation of star formation may be due to feedback mechanisms such as gas expulsion or consumption. Studying post-starburst galaxies can provide valuable insights into the processes of galaxy formation and evolution, as well as the mechanisms that regulate star formation activity in galaxies. These galaxies are also of interest in the context of understanding the formation and properties of early-type galaxies, as they may represent a key stage in the transformation of gas-rich, star-forming galaxies into gas-poor, quiescent systems.
