GASP. VII. Gas accretion onto an isolated galaxy
B. Vulcani, B. M. Poggianti, A. Moretti +7
Theoretically, inflowing filaments of gas are one of the main causes of growth for a galaxy. Nonetheless, observationally, probing ongoing gas accretion is challenging. As part of…
GASP. V. Ram-pressure stripping of a ring Hoag's-like galaxy in a massive cluster
A. Moretti, B. M. Poggianti, M. Gullieuszik +8
Through an ongoing MUSE program dedicated to study gas removal processes in galaxies (GAs Stripping Phenomena in galaxies with MUSE, GASP), we have obtained deep and wide integral…
Back to the green valley: how to rejuvenate an S0 galaxy through minor mergers
Michela Mapelli
About half of the S0 galaxies in the nearby Universe show signatures of recent or ongoing star formation. Whether these S0 galaxies were rejuvenated by the accretion of fresh gas i…
Building gas rings and rejuvenating S0 galaxies through minor mergers
Michela Mapelli, Roberto Rampazzo, Antonietta Marino
We investigate the effects of minor mergers between an S0 galaxy and a gas-rich satellite galaxy, by means of N-body/smoothed particle hydrodynamics (SPH) simulations. The satellit…
The impact of metallicity and dynamics on the evolution of young star clusters
M. Mapelli, A. A. Trani, A. Bressan
The early evolution of a dense young star cluster (YSC) depends on the intricate connection between stellar evolution and dynamical processes. Thus, N-body simulations of YSCs must…
Broad [OIII] in the globular cluster RZ 2109: X-ray ionized nova ejecta?
E. Ripamonti, M. Mapelli
We study the possibility that the very broad (~1500 km/s) and luminous (L_5007 ~ 1.4e37 erg/s) [OIII] line emission observed in the globular cluster RZ 2109 might be explained with…
