New Stellar Streams Confirm ‘Melting Pot’History of the Galaxy（图）
New Stellar Streams Melting Pot History of the Galaxy
2018/1/31
Where do the stars in our Galaxy come from? All the stars we see in the night-time sky belong to our Milky Way galaxy, and while most stars were likely born here, in the Milky Way, many appear to have...
Study of Andromeda's stellar disk indicates more violent history than Milky Way（图）
Andromeda's stellar more violent history Milky Way
2015/1/20
A detailed study of the motions of different stellar populations in the disk of the Andromeda galaxy has found striking differences from our own Milky Way, suggesting a more violent history of mergers...

Young stellar groups in M 33 galaxy: delineation and main parameters
2011/10/18
The problem of (non-)existence of a typical size of the stellar associations is revisited by use of deep UBVRI stellar CCD photometry in M 33 from the Local Group Survey (Massey et al. 2006). We compa...
Two generations in stellar complexes and associations in M 33 galaxy and their spatial correlation
generations stellar complexes associations galaxy spatial correlation
2011/10/18
Massive stellar content of stellar complexes and associations in M 33 is studied combining deep UBV photometry from the Local Group Survey (Massey et al. 2006) and JHK photometry from the 2MASS. Two b...
Another Look at the EBS: A Stellar Debris Stream and a Possible Progenitor
Another Look Stellar Debris Stream Possible Progenitor
2011/10/19
Using the Sloan Digital Sky Survey Data Release 7, we reexamine the Eastern Banded Structure (EBS), a stellar debris stream first discovered in Data Release 5 and more recently detected in velocity sp...
The outer haloes of the Milky Way and Andromeda galaxies contain as much important information on their assembly and formation history as the properties of the discs resident in their centres. In this...
Structure and Population of the NGC55 Stellar Halo from a Subaru/Suprime-Cam Survey
Population Stellar Halo Subaru Suprime-Cam Survey
2011/9/28
As part of our survey of galactic stellar halos, we investigate the structure and stellar populations of the northern outer part of the stellar halo in NGC55, a member galaxy of the Sculptor Group, us...
