Charting the Galactic acceleration field II. A global mass model of the Milky Way from the STREAMFINDER Atlas of Stellar Streams detected in Gaia DR3
Rodrigo Ibata, Khyati Malhan, Wassim Tenachi +17
We present an atlas and follow-up spectroscopic observations of 87 thin stream-like structures detected with the STREAMFINDER algorithm in Gaia DR3, of which 29 are new discoveries…
Could very low-metallicity stars with rotation-dominated orbits have been shepherded by the bar?
Zhen Yuan, Chengdong Li, Nicolas F. Martin +11
The most metal-poor stars (e.g. [Fe/H] ) are the ancient fossils from the early assembly epoch of our Galaxy, very likely before the formation of the thick disc. Recent s…
Exploring the impact of a rapidly decelerating bar on transforming bulge orbits into disc-like orbits
Chengdong Li, Zhen Yuan, Giacomo Monari +7
The most metal-poor tail of the Milky Way ([Fe/H] 2.5) contains a population of stars with very prograde planar orbits, which is puzzling in both their origin and evoluti…
Micro galaxies in LCDM
Raphaël Errani, Rodrigo Ibata, Julio F. Navarro +2
A fundamental prediction of the Lambda Cold Dark Matter (LCDM) cosmology is the centrally divergent cuspy density profile of dark matter haloes. Density cusps render CDM haloes res…
Strong constraints on the gravitational law from DR3 wide binaries
Indranil Banik, Charalambos Pittordis, Will Sutherland +4
We test Milgromian dynamics (MOND) using wide binary stars (WBs) with separations of kAU. Locally, the WB orbital velocity in MOND should exceed the Newtonian prediction by…
