A distribution-function estimate of the Milky Way mass profile from outer halo stars in DESI DR2
Gustavo E. Medina, Thomas M. Callingham, Monica Valluri +65
We present measurements of the Milky Way mass using blue horizontal-branch (BHB) and RR Lyrae (RRL) stars from the second data release of DESI (DR2), covering its first three years…
Constraining the Milky Way Mass profile with data driven distribution function using DESI DR2 halo stars
Yanrui Zhou, Jiaxin Han, Wenting Wang +57
We employ a novel data-driven dynamical modeling method, the empirical distribution function (emPDF), to constrain the Milky Way mass profile using a large sample of halo stars fro…
Mock catalogues for the DESI DR2 Milky Way mass modeling effort
Alexander H. Riley, Amanda Byström, Gustavo E. Medina +54
The Dark Energy Spectroscopic Instrument (DESI) survey is an ongoing campaign to obtain millions of spectra, including for stars within the Milky Way. One of DESI's Key Projects fo…
DESI DR2 Results III: The Mass of the Milky Way
DESI Collaboration, C. Aganze, J. Aguilar +113
We present measurements of the mass of the Milky Way using distant halo stars selected from the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (DR2). We apply four dyna…
