Evidence from the h3 survey that the stellar halo is entirely comprised of substructure

RP Naidu, C Conroy, A Bonaca… - The Astrophysical …, 2020 - iopscience.iop.org
In the ΛCDM paradigm, the Galactic stellar halo is predicted to harbor the accreted debris of
smaller systems. To identify these systems, the H3 Spectroscopic Survey, combined with …

The mass distribution and gravitational potential of the Milky Way

PJ McMillan - Monthly Notices of the Royal Astronomical Society, 2016 - academic.oup.com
We present mass models of the Milky Way created to fit observational constraints and to be
consistent with expectations from theoretical modelling. The method used to create these …

Proper motions and dynamics of the Milky Way globular cluster system from Gaia DR2

E Vasiliev - Monthly Notices of the Royal Astronomical Society, 2019 - academic.oup.com
Abstract We use Gaia Data Release 2 to determine the mean proper motions for 150 Milky
Way globular clusters (almost the entire known population), with a typical uncertainty of 0.05 …

Stellar initial mass function varies with metallicity and time

J Li, C Liu, ZY Zhang, H Tian, X Fu, J Li, ZQ Yan - Nature, 2023 - nature.com
Most structural and evolutionary properties of galaxies strongly rely on the stellar initial mass
function (IMF), namely the distribution of the stellar mass formed in each episode of star …
