The tidal tails of stellar clusters are an important tool for studying the clusters’ birth conditions, their evolution, coupling, and interaction with the...
CharlaA tale of caution: the tails of open clusters are much longer than thought, but more difficult to find
CharlaBlack holes in globular clusters
In the past few years, a series of discoveries have been made of objects which appear to be accreting stellar mass black holes in globular clusters -- both in...
CharlaChemical Cartography in the Milky Way with SDSS/APOGEE
The SDSS Apache Point Observatory Galactic Evolution Experiment (APOGEE) hascollected high resolution near-IR spectra of several hundred thousand starsacross...
CharlaCosmic variance in [O/Fe] in the Galactic disk
The detection of chemical inhomogeities in the Galactic disk requires an oustanding precision in the abundance measurements and a thorough estimation of the...
