Journal Article
van de Voort, F., Bahé, Y., Bower, R., Correa, C., Crain, R., Schaye, J., & Theuns, T. (2017). The environmental dependence of gas accretion onto galaxies: quenching satellites through starvation. Monthly Notices of the Royal Astronomical Society, 466(3), 3460-3471. https://doi.org/10.1093/mnras/stw3356

Galaxies that have fallen into massive haloes may no longer be able to accrete gas from their surroundings: a process referred to as ‘starvation’ or ‘strangulation’ of satellites. We study the environmental dependence of gas accretion on to galaxies... Read More about The environmental dependence of gas accretion onto galaxies: quenching satellites through starvation.
