The recurrent impact of the Sagittarius dwarf on the star formation history of the Milky Way
T Ruiz-Lara, C Gallart, EJ Bernard, S Cassisi - Nature Astronomy, 2020 - nature.com
Satellites orbiting disk galaxies can induce phase space features such as spirality, vertical
heating and phase-mixing in their disks. Such features have also been observed in our own …

A definitive merger-AGN connection at z ∼ 0 with CFIS: mergers have an excess of AGN and AGN hosts are more frequently disturbed
The question of whether galaxy mergers are linked to the triggering of active galactic nuclei
(AGN) continues to be a topic of considerable debate. The issue can be broken down into …

Star formation is boosted (and quenched) from the inside-out: radial star formation profiles from MaNGA
The tight correlation between total galaxy stellar mass and star formation rate (SFR) has
become known as the star-forming main sequence. Using∼ 487 000 spaxels from galaxies …
