Today we publicly release COSMOS2020, a catalogue of almost a million sources with photometric redshifts and stellar masses in the COSMOS field. COSMOS2020 is described fully in this paper, which has been accepted for publication in the Astrophysical Journal. We are also providing a python notebook showing how to use the catalogues. Released around five… Read More »
This week (11-15 June 2018) we are attending the Euclid consortium meeting in Bonn. We will be explaining of course why the CALET project is important for a space-based observatories like Euclid!
So, what is the origin of cosmic structures? In particular, the walls, sheets and filaments composed of galaxies and galaxy clusters? Although the seeding of these structures by tiny fluctuations in the cosmic microwave background remains our dominant paradigm for galaxy formation, there are still — of course — unanswered questions. In particular, what role… Read More »
The CALET project is a collaboration to process, distribute and analyse ground and space-based imaging data in the Euclid calibration and deep fields. It builds on the foundation of the TERAPIX project (1997-2017), which was a national service to reduce data from wide-field cameras and in particular data from CFHT‘s MEGACAM camera. CALET aims to provide… Read More »
