Resolving the pre-processing of galaxies in groups and filaments with MUSE
Galaxies inhabit a wide range of environments and therefore are affected by different physical mechanisms. Spatially resolved maps combined with the knowledge of the hosting environment are very powerful to classify galaxies by physical process. I will present some breakthrough results based on the GAs Stripping Phenomena in...

Stellar clustering connecting the formation and evolution of galaxies to the formation and evolution of us
The clustered nature of star formation leaves a long-term imprint on galaxies, stars, and planets. At young ages, stellar clustering subdivides galaxies into individual building blocks undergoing vigorous, feedback-driven life cycles that vary with the galactic environment. These units...

The cosmic rest frame
It is generally believed that the dipole of the cosmic microwave sky is defining the cosmic rest
frame. I will summarise the status of the corresponding measurements across frequencies from the radio
to the highest photon energies and argue that our knowledge of the cosmic rest frame is much less
precise than our knowledge of the CMB dipole. I'll discuss the impact of that...
