A solution to the paradox of youth in the Galactic centre

Rodrigo P. Silva, Alexandre C. M. Correia, Tjarda C. N. Boekholt +1

The supermassive black hole at the Galactic centre, Sgr A*, is surrounded by an S cluster of young stars. These stars are predominantly B-type stars, but their origin remains uncer…

From inter-filamentary gas to filaments and hubs: gas flows in the Mon R2 hub-filament system

Jihye Hwang, Doris Arzoumanian, Yoshito Shimajiri +5

Hub-filament systems (HFSs) play an important role in the formation of massive stars and star clusters. Although the velocity structures along dense filaments have been studied, th…
