Final CFHTLS TERAPIX dataset available at CALET

The Canada-France-Hawaii Telescope Legacy survey, or CFHTLS, was a wide-field survey sky-survey carried out using the Megacam camera on CFHT. CFHTLS had two components: a “wide” and “deep” survey. The deep survey comprised four deep fields observed in ugriz bands and the wide survey was a shallower survey covering around 140 square degrees in five… Read More »

Thesis project: finding the highest redshift galaxies and galaxy clusters

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

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 »
