Testing black hole space-times with the S2 star orbit: a Bayesian comparison
César Navarrete, Fernando Vázquez-Chávez, Alejandro Cruz-Osorio +1
We implement a Markov Chain Monte Carlo method to obtain posterior probability distributions for the parameters of the S2 star orbit around Sagittarius A*, for seven representative…

The distant Milky Way halo from the Southern hemisphere: Characterization of the LMC-induced dynamical-friction wake
Manuel Cavieres, Julio Chanamé, Camila Navarrete +6
The infall of the Large Magellanic Cloud (LMC) into the Milky Way's halo impacts the distribution of stars and dark matter in our Galaxy. Mapping the observational consequences of…
