The spatially resolved star formation history of the dwarf spiral galaxy NGC 5474
G. Bortolini, M. Cignoni, E. Sacchi +16
We study the resolved stellar populations and derive the star formation history of NGC 5474, a peculiar star-forming dwarf galaxy at a distance of Mpc, using Hubble Space…
The most stringent upper limit from dynamical models on the mass of a central black hole in 47 Tucanae
Alessandro Della Croce, Raffaele Pascale, Eric Giunchi +3
Globular clusters (GCs) were proposed as promising sites for discovering intermediate-mass black holes (IMBHs), possibly providing crucial insights into the formation and evolution…
Shaping the unseen: the influence of baryons and environment on low-mass, high-redshift dark matter haloes in the SIEGE simulations
R. Pascale, F. Calura, A. Lupi +7
We use zoom-in, hydrodynamical, cosmological -body simulations tracing the formation of the first stellar clumps from the SImulating the Environments where Globular clusters Eme…
Testing QUMOND theory with Galactic globular clusters in a weak external field
A. Sollima, C. Nipoti, F. Calura +2
We developed self-consistent dynamical models of stellar systems in the framework of quasi-linear modified Newtonian dynamics (QUMOND). The models are constructed from the anisotro…
Galactic coronae in Milky Way-like galaxies: the role of stellar feedback in gas accretion
Filippo Barbani, Raffaele Pascale, Federico Marinacci +4
Star-forming galaxies like the Milky Way are surrounded by a hot gaseous halo at the virial temperature - the so-called galactic corona - that plays a fundamental role in their evo…
An extremely metal poor star complex in the reionization era: Approaching Population III stars with JWST
E. Vanzella, F. Loiacono, P. Bergamini +31
We present JWST/NIRSpec integral field spectroscopy (IFS) of a lensed Population III candidate stellar complex (dubbed Lensed And Pristine 1, LAP1), with a lensing-corrected stella…
Clues on the presence and segregation of very massive stars in the Sunburst Lyman-continuum cluster at z=2.37
U. Mestric, E. Vanzella, A. Upadhyaya +15
We report the identification of very massive stars (VMS; mass \,\msun) that may be segregated in the center of the young massive star cluster at =2.37 hosted in the lense…
