Red nuggets, massive ultra-compact red galaxies, are already scarce at redshift z>2, but at lower redshift become even rarer. Recently, different works contributed to the census of relics at z < 0.5, gathering less than 100 candidates, leaving the intermediate redshift still unexplored. The pioneering sample of red nuggets at intermediate redshift discovered with the VIPERS survey (Lisiecki et al., submitted) provides the next step to understanding the evolution of massive galaxies.

The rapidly rotating neutron stars can be source of gravitational waves. I will present the methods used to find almost monochromatic signals detected by ground-base gravitation waves detectors.

The pipeline F-statistics used by our group, and pipelines other groups. The talk will describe a present stage and what to expect in close future.
