Astroclimate at San Pedro Mártir I: 2004-2008 Seeing Statistics from the TMT Site Testing Data
L. J. Sánchez, I. Cruz-González, J. Echevarría +6
We present comprehensive seeing statistics for the San Pedro Mártir site derived from the Thirty Meter Telescope site selection data. The observations were obtained between 2004 an…
Star formation in HI tails: HCG 92, HCG 100 and 6 interacting systems
D. F. de Mello, F. Urrutia-Viscarra, C. Mendes de Oliveira +3
We present new Gemini spectra of 14 new objects found within the HI tails of Hickson Compact Groups 92 and 100. Nine of them are GALEX Far-UV (FUV) and Near-UV (NUV) sources. The s…
Early-type galaxies at z = 1.3. I. The Lynx supercluster: cluster and groups at z=1.3. Morphology and color-magnitude relation
Simona Mei, S. Adam Stanford, Brad P. Holden +18
We confirm the detection of 3 groups in the Lynx supercluster, at z~1.3, and give their redshifts and masses. We study the properties of the group galaxies as compared to the centr…
Ultra deep sub-kpc view of nearby massive compact galaxies
Ignacio Trujillo, Eleazar R. Carrasco, Anna Ferre-Mateu
Using Gemini North telescope ultra deep and high resolution (sub-kpc) K-band adaptive optics imaging of a sample of 4 nearby (z~0.15) massive (~10^{11}M_sun) compact (R<1.5 kpc) ga…
