PublicaciónStray-light contamination and spatial deconvolution of slit-spectrograph observations
Context. Stray light caused by scattering on optical surfaces and in the Earth's atmosphere degrades the spatial resolution of observations. Whereas post-facto...

PublicaciónStrong chemical tagging with APOGEE: 21 candidate star clusters that have dissolved across the Milky Way disc
Chemically tagging groups of stars born in the same birth cluster is a major goal of spectroscopic surveys. To investigate the feasibility of such strong...

PublicaciónStrong size evolution of disc galaxies since z = 1. Readdressing galaxy growth using a physically motivated size indicator
Our understanding of how the size of galaxies has evolved over cosmic time is based on the use of the half-light (effective) radius as a size indicator...

PublicaciónStructural parameters of 389 local open clusters
Context. The distribution of member stars in the surroundings of an open cluster (OC) can shed light on the process of its formation, evolution, and dissolution...
