Is the star formation rate in quasars overestimated?
Fabio Di Mascia, Stefano Carniani, Simona Gallerani +4
The large total infrared (TIR) luminosities () observed in quasars are generally converted into high star formation rates ($SFR \gtr…
Abundance analysis of APOGEE spectra for 58 metal-poor stars from the bulge spheroid
R. Razera, B. Barbuy, T. C. Moura +19
The central part of the Galaxy host a multitude of stellar populations, including the spheroidal bulge stars, stars moved to the bulge through secular evolution of the bar, inner h…
Insights on the origin of ORCs from cosmological simulations
Klaus Dolag, Ludwig M. Böss, Bärbel S. Koribalski +2
We investigate shock structures driven by merger events in high-resolution simulations that result in a galaxy with a virial mass M ~ 1e12 Msol. We find that the sizes and morpholo…
Impact of H-driven star formation and stellar feedback from low-enrichment environments on the formation of spiral galaxies
Milena Valentini, Klaus Dolag, Stefano Borgani +8
The reservoir of molecular gas (H) represents the fuel for the star formation (SF) of a galaxy. Connecting the star formation rate (SFR) to the available H is k…
The role of physical and numerical viscosity in hydrodynamical instabilities
Tirso Marin-Gilabert, Milena Valentini, Ulrich P. Steinwandel +1
The evolution of the Kelvin-Helmholtz Instability (KHI) is widely used to assess the performance of numerical methods. We employ this instability to test both the smoothed particle…
Galaxies in the central regions of simulated galaxy clusters
Antonio Ragagnin, Massimo Meneghetti, Luigi Bassini +20
In this paper, we assess the impact of numerical resolution and of the implementation of energy input from AGN feedback models on the inner structure of cluster sub-haloes in hydro…
