Congratulations to the Vatican Observatory’s very own Fr. Richard D’Souza, S.J., for his recent article publication: The infall of dwarf satellite galaxies are influenced by their host’s massive accretions, co-authored by Professor Eric F. Bell from the University of Michigan.

Through his career, Fr. D’Souza has focused his study on the formation and evolution of galaxies. In particular, through observations and simulations, he studies the outer stellar halos of galaxies in order to decipher their accretion histories.

In this article, the authors explore recent progress in constraining the massive accretions experienced by the Milky Way and the Andromeda galaxy, and the opportunity this provides to better understand the dwarf galaxy population of the Local Group.
