Bar-induced deflection of open cluster tidal tails
Hanna Parul, Laia Casamiquela, Paola Di Matteo +1
We present a systematic study of how the Galactic bar affects the orientation of tidal tails of open clusters and assess the power of tail morphology to constrain the bar's pattern…
The Nephele ecosystem: stars, globular clusters, and stellar streams associated with the progenitor galaxy of Centauri
G. Pagnini, P. Di Matteo, M. Haywood +7
Globular clusters (GCs) and their associated stellar streams are key tracers of the hierarchical assembly history of the Milky Way. Centauri, the most massive and chemically c…
Asymmetries in stellar streams induced by a galactic merger
Claire Guillaume, Florent Renaud, Nicolas F. Martin +6
Stellar streams are sensitive to perturbations from, e.g., giant molecular clouds, bars and spiral arms, infalling dwarf galaxies, or globular clusters which can imprint gaps, clum…
Gaps in stellar streams as a result of globular cluster fly-bys
Salvatore Ferrone, Marco Montuori, Paola Di Matteo +10
Thin stellar streams, such as those resulting from the tidal disruption of globular clusters, have long been known and used as probes of the gravitational potential of our Galaxy,…
