Shear measurement bias: I. Dependencies on methods, simulation parameters, and measured parameters

Frédéric Courbin, Marc Gentile

We present a study of the dependencies of shear bias on simulation (input) and measured (output) parameters, noise, point-spread function anisotropy, pixel size, and the model bias coming from two different and independent galaxy shape estimators. We used ...

The Pristine survey IV: approaching the Galactic metallicity floor with the discovery of an ultra-metal-poor star

Pascale Jablonka, Carmela Lardo, Nicolas Lawrence Etienne Longeard, Marc Gentile, Silvia Martin de Nicolas Agut

The early Universe presented a star formation environment that was almost devoid of heavy elements. The lowest metallicity stars thus provide a unique window into the earliest Galactic stages, but are exceedingly rare and difficult to find. Here, we presen ...

The Pristine survey - III. Spectroscopic confirmation of an efficient search for extremely metal-poor stars

Pascale Jablonka, Marc Gentile

The Pristine survey is a narrow-band, photometric survey focused around the wavelength region of the Ca II H&K absorption lines, designed to efficiently search for extremely metal-poor stars. In this work, we use the first results of amedium-resolution spe ...
