NewsThe puzzle of the strange galaxy made of 99.99% dark matter is solved
At present, the formation of galaxies is difficult to understand without the presence of a ubiquitous, but mysterious component, termed dark matter. Astronomers...

PublicationThe puzzling interpretation of NIR indices: The case of NaI2.21
We present a detailed study of the Na I line strength index centred in the K band at 22 100 Å (NaI2.21 hereafter) relying on different samples of early-type...

PublicationThe puzzling merging cluster Abell 1914: new insights from the kinematics of member galaxies
We analyse the dynamical state of Abell 1914, a merging cluster hosting a radio halo, quite unusual for its structure. Our study considers spectroscopic data...
