Extreme chemical abundance ratio suggesting an exotic origin for an ultradiffuse galaxy
Monthly Notices of the Royal Astronomical Society(2019)
摘要
Ultradiffuse galaxies (UDGs) are a population of extended galaxies but with relatively low luminosities. The origin of these objects remains unclear, largely due to the observational challenges of the low surface brightness Universe. We present here a detailed stellar population analysis of a relatively isolated UDG, DGSAT I, based on spectroscopic data from the Keck Cosmic Web Imager integral fie...
