We present the Pristine survey, a new narrow-band photometric survey focused on the metallicity-sensitive Ca HK lines and conducted in the Northern hemisphere with the wide-field imager MegaCam on the Canada-France-Hawaii Telescope. This paper reviews our overall survey strategy and discusses the data processing and metallicity calibration. Additionally we review the application of these data to the main aims of the survey, which are to gather a large sample of the most metal-poor stars in the… 
The Pristine survey II: A sample of bright stars observed with FEROS†
Extremely metal-poor (EMP) stars are old objects formed in the first Gyr of the Universe. They are rare and, to select them the most successful strategy has been to build on large and low-resolution
The Pristine survey – VII. A cleaner view of the Galactic outer halo using blue horizontal branch stars
We use the Pristine survey CaHK narrow-band photometry, combined with the Sloan Digital Sky Survey (SDSS)ugr photometry, to provide a cleaner sample of blue horizontal branch stars in the Galactic
The Pristine survey – X. A large population of low-metallicity stars permeates the Galactic disc
The orbits of the least chemically enriched stars open a window on the formation of our Galaxy when it was still in its infancy. The common picture is that these low-metallicity stars are
The Pristine Inner Galaxy Survey (PIGS) II: Uncovering the most metal-poor populations in the inner Milky Way
Metal-poor stars are important tools for tracing the early history of the Milky Way, and for learning about the first generations of stars. Simulations suggest that the oldest metal-poor stars are to
The COMBS survey – I. Chemical origins of metal-poor stars in the Galactic bulge
Chemistry and kinematic studies can determine the origins of stellar population across the Milky Way. The metallicity distribution function of the bulge indicates that it comprises multiple
The Pristine survey – V. A bright star sample observed with SOPHIE
With the aim of probing the properties of the bright end of the Pristine survey and its effectiveness in selecting metal-poor stars, we selected a sample of bright candidate metal-poor stars
Pristine dwarf galaxy survey – I. A detailed photometric and spectroscopic study of the very metal-poor Draco II satellite
We present a detailed study of the faint Milky Way satellite Draco II (Dra II) from deep CFHT/MegaCam broad-band g and i photometry and narrow-band metallicity-sensitive CaHK observations, along with
The Pristine survey XI: the FORS2 sample
Extremely metal-poor (EMP) stars are old objects that mostly formed very early after the BigBang. They are rare and, to select them, we have to rely on low-resolution spectroscopic or photometric
The pristine dwarf-galaxy survey – III. Revealing the nature of the Milky Way globular cluster Sagittarius II
We present a new spectroscopic study of the faint Milky Way satellite Sagittarius II. Using multi-object spectroscopy from the Fibre Large Array Multi Element Spectrograph, we supplement the dataset
The COMBS Survey - II. Distinguishing the metal-poor bulge from the halo interlopers
Abstract The metal-poor stars in the bulge are important relics of the Milky Way’s formation history, as simulations predict that they are some of the oldest stars in the Galaxy. In order to
