The multiple routes of galaxy transformation across the cosmic epochs
In the local universe most of the stellar mass is in passive galaxies, where star formation isabsent or at very low levels. Understanding what are the...
The principle of maximum entropy explains the cores observed in the mass distribution of dwarf galaxies
Cold dark matter (CDM) simulations predict a central cusp in the mass distribution of galaxies. This prediction is in stark contrast with observations of dwarf...
Three sub-Jovian-mass microlensing planets: MOA-2022-BLG-563Lb, KMT-2023-BLG-0469Lb, and KMT-2023-BLG-0735Lb
Aims: We analyze the anomalies appearing in the light curves of the three microlensing events MOA-2022-BLG-563, KMT-2023-BLG-0469, and KMT-2023-BLG-0735. The...
Using globular clusters to test gravity in the weak acceleration regime: NGC 7099
Aims:A test of Newton's law of gravity in the low acceleration regime using globular clusters is presented and new results for the core collapsed globular...
A specific modification of Newtonian dynamics known as MOND has been shown to reproduce the dynamics of most astrophysical systems at different scales without...
