Metal-poor stars are key to our understanding of the early stages of chemical evolution in the Universe. New multi-filter surveys, such as the Southern Photometric Local Universe Survey (S-PLUS), are greatly advancing our ability to select low-metall

In this study we define a new sample of distant powerful radio galaxies in order to study their host-galaxy properties and provide targets for future observations of HI absorption with new radio telescopes and to understand the fuelling and feedback

The Abundance Pattern of $\alpha$ elements in the Triangulum-Andromeda Overdensity
Autor: H. J. Rocha-Pinto, F. Almeida-Fernandes, Hélio D Perottoni, S. R. Majewski, K. M. Cunha, Diogo Souto, Simone Daflon, J. V. Sales Silva
The close relationship between the nature of the Triangulum-Andromeda (TriAnd) overdensity and the Galactic disk has become increasingly evident in recent years. However, the chemical pattern of this overdensity (R$_{GC}$ = 20 - 30 kpc) is unique and

Dynamical equivalence, the origin of the Galactic field stellar and binary population, and the initial radius–mass relation of embedded clusters
Autor: Pavel Kroupa, Diogo Belloni, H. J. Rocha-Pinto, Mirek Giersz
Publikováno v: Monthly Notices of the Royal Astronomical Society. 474:3740-3745
In order to allow a better understanding of the origin of Galactic field populations, dynamical equivalence of stellar-dynamical systems has been postulated by Kroupa and Belloni et al. to allow mapping of solutions of the initial conditions of embed

Publikováno v: Proceedings of the International Astronomical Union. 14:122-124
The outer stellar halo is home to a number of substructures that are remnants of former interactions of the Galaxy with its dwarf satellites. Triangulum-Andromeda (TriAnd) is one of these halo substructures, found as a debris cloud by Rocha-Pinto et
