The PARADIGM project II: The lifetimes and quenching of satellites in Milky Way-mass haloes
Gandhali D. Joshi, Andrew Pontzen, Oscar Agertz +2
The abundance and star-formation histories of satellites of Milky Way (MW)-like galaxies are linked to their hosts' assembly histories. To explore this connection, we use the PARAD…

Jellyfish galaxies with the IllustrisTNG simulations -- Supermassive black hole activity in dense environments with ram-pressure stripped satellites
Shalini Kurinchi-Vendhan, Eric Rohr, Annalisa Pillepich +3
Jellyfish galaxies are extreme examples of how galaxies can transform due to dense environmental effects. These satellite galaxies suffer from ram-pressure stripping, leading to th…

The PARADIGM project I: How early merger histories shape the present-day sizes of Milky-Way-mass galaxies
Gandhali D. Joshi, Andrew Pontzen, Oscar Agertz +3
How mergers affect galaxy formation depends on both feedback processes, and on the geometry and strength of the mergers themselves. We introduce the PARADIGM project, where we stud…
