Laboratory and on-sky experience suggests that the integration of big astronomical instruments, specially of a complex interferometric system, is a challenging...

We recently discovered an unresolved radio source coincident with the ultraluminous X-ray source (ULX) IC 342 X-1. The radio emission and hard X-ray spectrum of...

We have performed photometric optical observations of a sample of 16 radio loud and 16 radio quiet quasars. The aims were to confirm the existence of...

Our primary goal is to characterize the surface composition (and other properties such as radius, albedo and thermal inertia) of our sample of Themis-family and...

The SONG spectrograph has recently demonstrated its ability to perform solar radial velocity measurement during the first test run of the Solar-SONG initiative...

Planetary Nebulae (PNe) are highly representative of the last stages of intermediate mass stellar evolution. However, there are still many unresolved questions...

We collect information for 88 broad absorption line quasars (BALQSOs) from the literature and existing catalogues, creating the largest BALQSOs sample analyzed...
