Work on halo parameters of spiral galaxies and
the core-cusp problem in low surface brightness galaxies (here
and here) showed that mass models of galaxies provide
constraints on the ΛCDM model
Later on, I worked on the S4G project and the associated
DAGAL EU network
Some baryonic dark matter got my interest recently: here and here
I now participate in projects using the SKA precursors ASKAP (WALLABY survey) and MeerKAT
(MHONGOOSE survey) for 21-cm HI line studies of galaxies,
and in the WEAVE-Apertif project
