Fingerprints of the properties of exotic nuclei on nucleosynthesis observables have been used for decades to frame our picture of how the heaviest elements in our Solar System came to be. The abundance of elements in our Sun, as well as nearby metal-poor stars, hints at multiple neutron capture nucleosynthesis processes, the slow (s), intermediate (i) and rapid (r) neutron capture processes....
Our Galaxy is filled with complex astronomical phenomena, ranging from star formation, planet formation, stellar interactions and mergers, accretion discs, tidal disruption events and more. Many of these systems and objects involve a diverse array of physics, such as magnetic fields, dust, or general relativity. This can make numerical simulations difficult to perform, as it means creating...
Axion-like particles have been gaining popularity recently as potential solutions to dark matter with fascinating wave-like dynamics. In this talk, I will specifically consider fuzzy or ultralight dark matter (FDM/ULDM): a candidate that keeps the successes of CDM on large scales but alleviates tensions on small scales. This small-scale behavior is due to characteristic observable cores in...
This paper proposes a conceptual framework that predicts the rotational velocity of spiral galaxies with respect to the radial distance from their center of mass, without hypothesizing about any dark matter. It is based on an emergent modified gravity paradigm derived from Einstein’s general relativity and relies on erfc scalar field metrics. A short recall of the previously published modified...
