Tracing M22's origins: Spatial and chemical constraints on its formation history

E. Dondoglio, Antonino P. Milone, Randa Asad, Anna F. Marino et autres

Globular clusters (GCs) are well known to host stellar populations characterized by light-element variations. A subset of Galactic GCs, beyond such 'canonical' populations, contains an additional group enriched in iron, s-process elements, and total C+N+O abundance (i.e., the anomalous stars). We combine …

When bars and spirals conspire: recurrent build-up of the nuclear regions of disc galaxies

Tristan Boin, Sergey Khoperskov, Paola Di Matteo, Nils Hoyer et autres

The assembly history of the central regions of disc galaxies is regulated by dynamical processes that trigger gas infall events, leading to active star formation in nuclear stellar discs (NSD) and in nuclear stellar clusters (NSC). In the Milky Way, recent studies …

The Lunar Gravitational-wave Antenna: mission studies and science case

P. Ajith, Pau Amaro Seoane, Manuel Arca Sedda, R. Arcodia et autres

The Lunar Gravitational-wave Antenna (LGWA) is a proposed array of next-generation inertial sensors to monitor the response of the Moon to gravitational waves (GWs). Given the size of the Moon and the expected noise produced by the lunar seismic background, the LGWA …

The JWST Galactic Center Survey -- A White Paper

R. Schödel, Steve Longmore, Jonny Henshaw, Adam Ginsburg et autres

The inner hundred parsecs of the Milky Way hosts the nearest supermassive black hole, largest reservoir of dense gas, greatest stellar density, hundreds of massive main and post main sequence stars, and the highest volume density of supernovae in the Galaxy. As …

Mergers, tidal interactions, and mass exchange in a population of disc globular clusters

Sergey A. Khoperskov, Alessandra Mastrobuono-Battisti, P. Di Matteo, M. Haywood

Globular clusters (GCs), the oldest stellar systems observed in the Milky Way, have long been considered single stellar populations. As such, they provided an ideal laboratory to understand stellar dynamics and primordial star formation processes. However, during the last two decades, observations …
