Star clusters as diaries of galaxies
Th. Maschberger, P. Kroupa
TL;DR
This paper discusses how the distribution of star clusters within a galaxy can reveal its star formation history, highlighting that massive clusters indicate periods of intense star formation.
Contribution
It introduces a method to derive a galaxy's star formation history from its star cluster content, based on the approach by Maschberger & Kroupa (2007).
Findings
Massive clusters form during high star formation episodes.
Periods of low star formation do not produce massive clusters.
The method links cluster distribution to galaxy star formation history.
Abstract
Most if not all stars form in star clusters. Thus the distribution of star clusters preserves the information on the star formation history of a galaxy. Massive clusters form only during episodes of high star formation activity whereas periods of low star formation activity cannot produce them. We present here the method of Maschberger & Kroupa (2007) to derive the star formation history of a galaxy from its star-cluster content.
