The Cheshire Cat Gravitational Lens: The Formation of a Massive Fossil Group
Jimmy A. Irwin, Renato Dupke, Eleazar R. Carrasco +3
The Cheshire Cat is a relatively poor group of galaxies dominated by two luminous elliptical galaxies surrounded by at least four arcs from gravitationally lensed background galaxi…
Witnessing gas mixing in the metal distribution of the Hickson Compact Group HCG 31
S. Torres-Flores, C. Mendes de Oliveira, P. Amram +3
We present, for the first time, direct evidence that, in a merger of disk galaxies, the preexisting central metallicities will mix as a result of gas being transported in the merge…
Astrometric performance of the Gemini multi-conjugate adaptive optics system in crowded fields
Benoit Neichel, Jessica R. Lu, Francois Rigaut +3
The Gemini Multi-conjugate adaptive optics System (GeMS) is a facility instrument for the Gemini-South telescope. It delivers uniform, near-diffraction-limited image quality at nea…
Strong Gravitational Lensing by the Super-massive cD Galaxy in Abell 3827
E. R. Carrasco, P. L. Gomez, T. Verdugo +6
We have discovered strong gravitational lensing features in the core of the nearby cluster Abell 3827 by analyzing Gemini South GMOS images. The most prominent strong lensing featu…
Witnessing the formation of a galaxy cluster at z=0.485: optical and X-ray properties of RX J1117.4+0743 ([VMF 98] 097)
E. R. Carrasco, E. S. Cypriano, G. B. Lima Neto +4
We present a multiwavelength study of the poor cluster RX J1117.4+0743 ([VMF 98] 097) at z=0.485, based on GMOS/Gemini South g', r' photometry and spectroscopy, and XMM-Newton obse…
