"GAMA + KiDS: empirical correlations between halo mass and other galaxy properties near the knee of the stellar-to-halo mass relation" - Taylor et al (2020)
Alan Duffy
My colleague A/Prof Edward ‘Ned’ Taylor did a spectacular job in this monster paper teasing out the connection between properties of the galaxy and its mass… the end result? The dark matter halo mass is more tightly linked to the galaxy’s structure than either the past or current star formation. That means that the stars that make up the galaxies structure are not as relevant as the size of the dark matter halo around it - which traditionally is assumed to play a minor, if any, role in that structure. A wonderful and counterintuitive result, congrats Ned!
