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…
