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

Stellar initial mass function varies with metallicity and time
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 …

Stellar halo substructure generated by bar resonances
Using data from the Gaia satellite's Radial Velocity Spectrometer Data Release 3 (RVS,
DR3), we find a new and robust feature in the phase-space distribution of halo stars. It is a …
