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…
Improved constraints on the Milky Way potential using the M68 stream and DESI spectroscopic data
Carles G. Palau, Wenting Wang, Jiaxin Han +41
We present a selection of stars belonging to the stellar stream of the M68 (NGC 4590) globular cluster, also known as Fjörm. This star selection is an improvement on previous ones…
The shape-velocity alignment of satellites forged by tidal locking and dynamical friction
Hao Yang, Wenting Wang, Ting S. Li +8
Utilizing the TNG50 simulation, we study two types of alignments for satellites/subhalos: 1) the alignment of their major axes with the galactocentric radial directions (radial ali…
Modelling the M68 stellar stream with realistic mass loss and frequency distributions in angle-action coordinates
Carles G. Palau, Wenting Wang, Jiaxin Han
We develop a new method for simulating stellar streams generated by globular clusters using angle-action coordinates. This method reproduces the variable mass-loss and variable fre…
The dark matter content of Milky Way dwarf spheroidal galaxies: Draco, Sextans and Ursa Minor
Hao Yang, Wenting Wang, Ling Zhu +50
The Milky Way Survey of the Dark Energy Spectroscopic Instrument (DESI) has so far observed three classical dwarf spheroidal galaxies (dSphs): Draco, Sextans and Ursa Minor. Based…
SpecDis: Value added distance catalogue for 4 million stars from DESI Year-1 data
Songting Li, Wenting Wang, Sergey E. Koposov +55
We present the SpecDis value added stellar distance catalog accompanying DESI DR1. SpecDis trains a feed-forward Neural Network (NN) with Gaia parallaxes and gets the distance esti…
Constraining the potential of the Milky Way using stellar streams and the Inverse Time Integration method
C. G. Palau, W. Wang, J. Han
We develop a method for constraining the potential of the Milky Way using stellar streams with a known progenitor. The method expresses the stream in angle-action coordinates and i…
Using two point correlation functions to understand the assembly histories of Milky Way-like galaxies
Yike Zhang, Wenting Wang, Jiaxin Han +4
The two point correlation function (2PCF) is a powerful statistical tool to measure galaxy clustering. Although 2PCF has also been used to study the clustering of stars on parsec a…
The oblateness of the Milky Way dark matter halo from the stellar streams of NGC 3201, M68, and Palomar 5
Carles G. Palau, Jordi Miralda-Escudé
We explore constraints on the Milky Way dark matter halo oblateness using three stellar streams from globular clusters NGC 3201, M68, and Palomar 5. Previous constraints on the gra…
The tidal stream generated by the globular cluster NGC 3201
C. G. Palau, J. Miralda-Escudé
We detect a tidal stream generated by the globular cluster NGC 3201 extending over ~140 degrees on the sky, using the Gaia DR2 data, with the maximum likelihood method we presented…
