Merging is an important process during the formation and evolution of galaxies and structures in the Universe.The massive ancient merger event of the Gaia-Sausage-Enceladus (GSE) has significantly reshaped our Galaxy....

We search for metal-rich Sausage-kinematic(MRSK)stars with[Fe/H]>−0.8 and−100
A combination of massive spectroscopic surveys and Gaia DR2 has brought light into the chemical and kinematical properties of a large number of stars,thus building up a mature picture of the Gaia-Sausage-Enceladus (GS...

This paper summarizes the challenges of identifying planetary-origin meteorites of non-igneous composition - particularly those of sedimentary origin.Evidence for putative sedimentary-origin (sedtype) meteorites and t...

We analyze the communicating pipe model on Enceladus, and predict that Saturn's strong tidal force in Enceladus plays a significant role in the plumes. In this model, the scale of the volcanoes can be evaluated based...
