Auriga Streams III: the mass-metallicity relation does not rule out tidal mass loss in Local Group satellites
Alexander H. Riley, Rebekka Bieri, Alis J. Deason +6
The mass-metallicity relation is a fundamental galaxy scaling law that has been extended to the faintest systems in the Local Group. We show that the small scatter in this relation…
Formation and evolution of boxy/peanut bulges in the Auriga cosmological simulations
Paula D. López, Francesca Fragkoudi, Sofía A. Cora +5
Boxy/peanut (b/p) or X-shaped bulges have been extensively explored with theory and numerical simulations of isolated galaxies. However, it is only recently that advances in hydrod…
The special growth history of central galaxies in groups and clusters
Carlo Nipoti
Central galaxies (CGs) in galaxy groups and clusters are believed to form and assemble a good portion of their stellar mass at early times, but they also accrete significant mass a…
Efficiency of gas cooling and accretion at the disc-corona interface
L. Armillotta, F. Fraternali, F. Marinacci
In star-forming galaxies, stellar feedback can have a dual effect on the circumgalactic medium both suppressing and stimulating gas accretion. The trigger of gas accretion can be c…
Gaussian random field power spectrum and the Sérsic law
Carlo Nipoti
The surface-brightness profiles of galaxies are well described by the Sérsic law: systems with high Sérsic index m have steep central profiles and shallow outer profiles, while sys…
