First evidence of a collision between two unrelated open clusters in the Milky Way
Andrés E. Piatti, Khyati Malhan
We report the first evidence of an on-going collision between two star clusters in our Galaxy, namely IC 4665 and Collinder 350. These are open clusters located at a distance of ~3…
DECam photometry reveals extra-tidal stars around the Milky Way globular cluster NGC 6864 (M75)
Andrés E. Piatti
Globular clusters are prone to lose stars while moving around the Milky Way. These stars escape the clusters and are distributed throughout extended envelopes or tidal tails. Howev…
Revisiting a detached stellar structure in the outer northeastern region of the Small Magellanic Cloud
Andrés E. Piatti
The outer northeastern region of the Small Magellanic Cloud (SMC) is populated by a shell-like overdensity whose nature was recently investigated. We analyzed twenty catalogued sta…
Residual velocities of Small Magellanic Cloud star clusters
Andrés E. Piatti
We analyzed the largest Small Magellanic Cloud (SMC) cluster sample (32) with proper motions and radial velocity measurements, from which we obtained their space velocity component…
Globular cluster candidates in the Sagittarius dwarf galaxy
Andrés E. Piatti
Recently, new Sagittarius (Sgr) dwarf galaxy globular clusters were discovered, which opens the question on the actual size of the Sgr globular cluster population, and therefore on…
The surroundings of the Milky Way globular cluster NGC 6809
Andrés E. Piatti
We study the outer regions of the Milky Way globular cluster NGC6809 based on Dark Energy Camera (DECam) observations, which reach nearly 6 mag below the cluster main sequence (MS)…
