The advanced evolution of massive stars: I. New reaction rates for carbon and oxygen nuclear reactions
T. Dumont, A. Bonhomme, A. Griffiths +9
The nuclear rates for reactions involving 12C and 16O are key to compute the energy release and nucleosynthesis of massive stars during their evolution. These rates shape the stell…

A cosmic degeneracy story: structure formation with warm dark matter and scale-dependent primordial non-Gaussianities
Clément Stahl, Benoit Famaey, Rodrigo Ibata +2
It has been recently shown that cosmological models with scale-dependent primordial non-Gaussianities (sPNG) could provide a possible path to solve current cosmic tensions. Moreove…
