The nuclear infrared emission of low-luminosity active galactic nuclei
Low-luminosity AGN (LLAGN; LINERs and low-luminosity Seyferts) are present in numerous nearby galaxies and are often suggested to be the "missing link" between...
The centers of massive galaxies are special in many ways, not least because all of them are believed to host supermassive black holes. Since the discovery of a...
The occurrence and properties of nuclear star clusters in Virgo over seven decades in stellar mass, and what they tell us about their host galaxies
Nuclear star clusters (NSCs) are compact stellar systems that inhabit the central regions of many galaxies, including the Milky Way. They tend to be larger and...
The origin of the Galactic halo as traced by globular clusters
The assembly history of the stellar halo of our Galaxy might be encoded in the kinematics, metallicities, ages and spatial distribution of the tidal streams...
Some answers to current questions about the formation and evolution of dwarf galaxies are based on the detection and study of increasingly weak sources. The...
The parallelism between early-type galaxies and clusters
I will review the properties of nearby early-type galaxies and galaxy clusters showing the most interesting observed parallelisms, such as the Sersic behavior...
