Tails and streams around the Galactic globular clusters NGC 1851, NGC 1904, NGC 2298 and NGC 2808
(Oxford University Press, 2018)
We present Dark Energy Camera imaging for the peculiar Galactic globular clustersNGC 1851, NGC1904 (M 79), NGC2298 and NGC2808. Our deep photometry reveals that all the clusters have an important contribution of stars ...
Testing Newtonian gravity with distant globular clusters: NGC 1851 and NGC 1904
(2011)
Context. Globular clusters are useful for testing the validity of Newtonian dynamics in the low acceleration regime typical of galaxies, without the complications of non-baryonic dark matter. In the absence of disturbing ...

New Variable Stars in CMa Globular Cluster Candidates
(2011)
We present the preliminary results of an image-subtraction analysis of the Galactic globular cluster M79 (NGC 1904), as well as a new investigation of the variable star population in NGC 1851. Both M79 and NGC 1851 have ...
