Spatial Property of Multiple Metallic Populations in the Tidal Stream of ω Centauri
Shiru Zheng, Baitian Tang, Long Wang +4
ω Centauri, the remnant nucleus of an accreted dwarf galaxy, is a unique laboratory for studying complex stellar populations. The recently discovered Fimbulthul stream provides a f…
Cosmology with galaxy clusters using machine learning. Application to eROSITA Data
Fucheng Zhong, Nicola R. Napolitano, Johan Comparat +8
Context: We present the first Cosmological Parameter inferences from eROSITA X-ray observations of galaxy clusters using a Machine Learning algorithm. Methods: We train a Random Fo…
DarkAI: Reconstructing the density, velocity and tidal field of dark matter from a DESI-like bright galaxy sample
Feng Shi, Zitong Wang, Xiaohu Yang +10
Reconstructing the mass density, velocity, and tidal (MTV) fields of dark matter from galaxy surveys is essential for advancing our understanding of the LSS of the Universe. In thi…
Cosmic Web Classification through Stochastic Topological Ranking
Jaime E. Forero-Romero, Alejandro Palomino, Felipe Leonardo Gómez-Cortés +1
This paper introduces ASTRA (Algorithm for Stochastic Topological RAnking), a new method for classifying galaxies into cosmic web structures -- voids, sheets, filaments, and knots…
Searching for multiple populations in star clusters using the China Space Station Telescope
Chengyuan Li, Zhenya Zheng, Xiaodong Li +6
Multiple stellar populations (MPs) in most star clusters older than 2 Gyr, as seen by lots of spectroscopic and photometric studies, have led to a significant challenge to the trad…
