Optical emission line properties of eROSITA-selected SDSS-V galaxies

International audienceWe present and discuss optical emission line properties obtained from the analysis of spectra obtained in the Sloan Digital Sky Survey (SDSS) for an X-ray-selected sample of 3684 galaxies (0.002

Search for Dwarf Emission Line Galaxies in Galaxy Voids

, 2019
The population and formation of dwarf galaxies, Mr \u3e −14, contain clues about the nature of dark matter. The best place to search for these dwarf galaxies without influence from nearby large galaxies is within galaxy voids, where no galaxies have yet ...

Emission line gas in early-type galaxies: Kinematics and physical conditions

, 1993
Recent studies have found line emission gas in nearby early-type galaxies, but the properties of the emission-line gas in these 'normal' galaxies remain enigmatic.
