A deep observation of the ultraluminous X-ray source IC 342 X-1
Our recent detection of compact radio emission at the position of the ultraluminous X-ray source (ULX) IC 342 X-1 suggests the presence of an outflow in this...
A deep search for the host galaxies of GRBs with no detected optical afterglow
Long gamma-ray bursts (GRBs) pinpoint star-forming galaxies as they are linked to the deaths of massive stars. In most cases, these galaxies have been found to...
A deep, precise determination of the substellar mass function and its radial dependence in the open cluster IC 2391 from a multiband optical-infrared survey
A definitive census of the IMF of a nearby young massive cluster
Over the past years, we have performed one of the most extensive study of the young (lambda)-Orionis star forming region, combining photometric data from the...
In order to improve the understanding of the process of emergence of magnetic flux on the solar surface, we studied the temporal evolution of an ephemeral...
