Uncovering the dark matter distribution by combining stellar kinematics and integrated HI spectra: Method validation
Yu Lei, Meng Yang, Ling Zhu
We determined the dark matter (DM) distribution in galaxies by jointly modelling stellar kinematics from integral field unit (IFU) observations and the gaseous kinematics encoded i…
Tracing the relic nature of compact galaxies through their globular cluster systems
Micheli T. Moura, Ana L. Chies-Santos, Cristina Furlanetto +6
We investigate the synthetic model of globular cluster (GC) systems of 17 compact massive galaxies (CMGs) from the Illustris TNG100 simulation to explore their connection with mass…
Dark matter in ALFALFA galaxies: Investigating galaxy-halo connection
Meng Yang, Ling Zhu, Niankun Yu +4
This paper aims to investigate the galaxy-halo connection using a large sample of individual galaxies with integrated spectra. We determine their dark matter conten…
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…
Robust machine learning model of inferring the ex-situ stellar fraction of galaxies from photometric data
Runsheng Cai, Ling Zhu, Shiyin Shen +3
We search for parameters defined from photometric images to quantify the ex situ stellar mass fraction of galaxies. We created mock images using galaxies in the cosmological hydrod…
