The exact nature of the arms of spiral galaxies is still an open question1. It has been widely assumed that spiral arms in galaxies with two distinct symmetrical arms are the products of density waves that propagate around the disk, with the spiral a...

Chromodynamical analysis of lenticular galaxies using globular clusters and planetary nebulae. Monthly Notices of the Royal Astronomical Society, https://doi.org/10.1093/mnras/sty1737

Recovering the origins of lenticular galaxies can shed light on the understanding of galaxy formation and evolution, since they present properties that can be found in both elliptical and spiral galaxies. In this work we study the kinematics of the g... Read More about Chromodynamical analysis of lenticular galaxies using globular clusters and planetary nebulae.

Spectroscopic decomposition of the galaxy and halo of the cD galaxy NGC 3311 (2018)

Information on the star-formation histories of cD galaxies and their extended stellar haloes lie in their spectra. Therefore, to determine whether these structures evolved together or through a two-phase formation, we need to spectroscopically separa...
