Introducing COSMOS2020

By | October 28, 2021

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 »

Thesis project: finding the highest redshift galaxies and galaxy clusters

By | February 8, 2018

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 »

Introducing the CALET project

By | January 23, 2018

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 »
