A Closer Look at the Origin of LINER Emission in Later-type Galaxies and Its Connection to Evolved Stars with a Machine Learning Classification Scheme
Identifying the dominant ionizing sources in galaxies is essential for understanding their formation and evolution.Traditionally, spectra are classified based on their dominant ionizing source using strong emission lines and Baldwin, Phillips, & Terlevich (BPT) diagrams.The ionizing source is traditionally determined by the emission line ratios usi
