Chemical evolution of the metal poor Globular Cluster NGC 6809
M. J. Rain, S. Villanova, C. Muñoz +1
We present the abundances analysis for a sample of 11 red giant branch stars in the metal-poor globular cluster NGC 6809 based on high-resolution spectra. Our main goals are to cha…

Semi-simple enlargement of the algebra from a Chern-Simons theory
Patrick Concha, Nelson Merino, Evelyn Rodríguez +2
In this work we present a BMS-like ansatz for a Chern-Simons theory based on the semi-simple enlargement of the Poincaré symmetry, also known as AdS-Lorentz algebra. We start by sh…

Asymptotic symmetries of three-dimensional Chern-Simons gravity for the Maxwell algebra
Patrick Concha, Nelson Merino, Olivera Miskovic +3
We study a three-dimensional Chern-Simons gravity theory based on the Maxwell algebra. We find that the boundary dynamics is described by an enlargement and deformation of the $\ma…
