  • The image shows a slice of a numerical model for dark matter (grey points) and galaxies. Two types of galaxies are shown: bright emission line galaxies (filled circles) and those galaxies hosted by gravitational potentials above a threshold such that the number density equals that of the emission line galaxies (open circles). 
This figure illustrates that emission line galaxies trace different features from the cosmic web than galaxies selected by either their stellar mass or the strength of the gravitational potential where they have formed.

  • The image shows the location of some the emission line galaxies observed in the study (green circles) against the images of a big patch of the sky as observed by The Dark Energy Camera Legacy Survey (DECaLS) http://legacysurvey.org/decamls/

  • The image shows nearby emission line galaxies NCG 4038 - 4039. The pink parts in this image are showing the light from the gas heated by newly formed stars.
