A new member of the Milky Way's family tree: Characterizing the Pontus merger of our Galaxy

Khyati Malhan

We study the structure -- a recently discovered merger that brought in globular clusters in the course of the hierarchical build-up of the Milky Way's hal…

The Pristine Inner Galaxy Survey (PIGS) IV: A photometric metallicity analysis of the Sagittarius dwarf spheroidal galaxy

Sara Vitali, Anke Arentsen, Else Starkenburg +15

We present a comprehensive metallicity analysis of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) using photometry. We base our member selection on EDR3…

The Pristine survey XVIII: C-19: Tidal debris of a dark matter-dominated globular cluster?

Raphaël Errani, Julio F. Navarro, Rodrigo Ibata +12

The recently discovered C-19 stellar stream is a collection of kinematically associated metal-poor stars in the halo of the Milky Way lacking an obvious progenitor. The stream span…

The Pristine survey -- XVII. The C-19 stream is dynamically hot and more extended than previously thought

Zhen Yuan, Nicolas F. Martin, Rodrigo A. Ibata +22

The C-19 stream is the most metal poor stellar system ever discovered, with a mean metallicity . Its low metallicity dispersion ( 0.18 at…

The Global Dynamical Atlas of the Milky Way mergers: Constraints from Gaia EDR3 based orbits of globular clusters, stellar streams and satellite galaxies

Khyati Malhan, Rodrigo A. Ibata, Sanjib Sharma +7

The Milky Way halo was predominantly formed by the merging of numerous progenitor galaxies. However, our knowledge of this process is still incomplete, especially in regard to the…

Estimating the local dark matter density in a non-axisymmetric wobbling disc

S. Sivertsson, J. I. Read, H. Silverwood +6

The density of dark matter near the Sun is important for experiments hunting for dark matter particles in the laboratory, and for constraining the local shape of the Milky Way's da…
