Mixed Early and Late-Type Properties in the Bar of NGC 6221: Evidence for Evolution along the Hubble Sequence?
J. C. Vega Beltran, W. W. Zeilinger, P. Amico +5
Rotation curves and velocity dispersion profiles are presented for both the stellar and gaseous components along five different position angles (P.A.=5, 50, 95, 125 and 155 degrees…
Internal Proper-Motions in the Eskimo Nebula
Ma. T. GarcÃa-DÃaz, L. Gutiérrez, W. Steffen +2
We present measurements of internal proper motions at more than five hundred positions of NGC 2392, the Eskimo Nebula, based on images acquired with WFPC2 on board the Hubble Space…
Unveiling The Physics of Star Formation and Feedback in Galaxies
F. S. Tabatabaei, J. Braine, C. Kramer +3
Recent studies show the importance of feedback in the evolution of the star formation rate in the Universe. However, the nature and physics of the feedback are still pressing quest…
GH FaS : Galaxy H-alpha Fabry-Perot System for the WHT
O. Hernandez, K. Fathi, C. Carignan +11
GHFaS a new Fabry-Perot system, is now available at the William Herschel Telescope. It was mounted, for the first time, at the Nasmyth focus of the 4.2 meter WHT on La Palma in…
Unveiling the environment and faint features of the isolated galaxy CIG 96 with deep optical and HI observations
P. Ramirez-Moreta, L. Verdes-Montenegro, J. Blasco-Herrera +21
Asymmetries in HI in galaxies are often caused by the interaction with close companions, making isolated galaxies an ideal framework to study secular evolution. The AMIGA project h…
