WSRT and WHT working together
| Submitter: | Raffaella Morganti |
| Description: | Images representing the motion of gas and stars in the galaxy NGC4278. The red regions are moving away from us, the blue are approaching us. The figure represent a nice example of complementary data based on dutch instruments. On the left the neutral hydrogen as measured by the WSRT, on the right the ionized gas (bottom) and stars (top) as measured by the integral field spectrograph SAURON on the William Herschel Telescope on La Palma. Note the different scales that the two instruments can image: the SAURON data cover the very inner part of the HI image (black box). The results of this study are presented in a paper accepted for publication in MNRAS (Morganti, de Zeeuw, Oosterloo et al. http://xxx.lanl.gov/abs/astro-ph/0606261). |
