Metallicity gradients in Local Universe galaxies: time evolution and effects of radial migration
L. Magrini, L. Coccato, L. Stanghellini +2
Our knowledge of the shape of radial metallicity gradients in disc galaxies has recently improved. Conversely, the understanding of their time evolution is more complex, since it r…
Cosmic-ray ionisation in collapsing clouds
Marco Padovani, Patrick Hennebelle, Daniele Galli
Cosmic rays (CR) play an important role in dense molecular cores, affecting their thermal and dynamical evolution and initiating the chemistry. Several studies have shown that the…
A candidate circumbinary Keplerian disk in G35.20-0.74 N: A study with ALMA
A. Sanchez-Monge, R. Cesaroni, M. T. Beltran +13
We report on ALMA observations of continuum and molecular line emission with 0.4" resolution towards the high-mass star forming region G35.20-0.74 N. Two dense cores are detected i…
Reflection and dissipation of Alfvén waves in interstellar clouds
C. Pinto, A. Verdini, D. Galli +1
Context: Supersonic nonthermal motions in molecular clouds are often interpreted as long-lived magnetohydrodynamic (MHD) waves. The propagation and amplitude of these waves is affe…
A view of the Galactic halo using beryllium as a time scale
Rodolfo Smiljanic, L. Pasquini, P. Bonifacio +4
Beryllium stellar abundances were suggested to be a good tracer of time in the early Galaxy. In an investigation of its use as a cosmochronometer, using a large sample of local hal…
CCH in prestellar cores
M. Padovani, C. M. Walmsley, M. Tafalla +2
We study the abundance of CCH in prestellar cores both because of its role in the chemistry and because it is a potential probe of the magnetic field. We also consider the non-LTE…
