HI in the shell elliptical NGC 3656
M. Balcells, J. H. van Gorkom, R. Sancisi +1
VLA neutral hydrogen observations of the shell elliptical NGC 3656 reveal an edge-on, warped minor axis gaseous disk (M_HI ~ 2.10^9 Msun) extending 7 kpc. HI is also found outside…
A detailed two-dimensional stellar population study of M32
C. del Burgo, R. F. Peletier, A. Vazdekis +2
We present Two-Dimensional Spectroscopy of the 9x12 arcsec^2 central region of M32 obtained with the 2D_FIS fibre spectrograph installed at the William Herschel Telescope. From the…
Two-Dimensional Line Strength Maps in Three Well-studied Early-Type Galaxies
Reynier F. Peletier, Alexandre Vazdekis, Santiago Arribas +5
Integral field spectroscopy has been obtained for the nuclear regions of 3 large, well-studied, early-type galaxies. From these spectra we have obtained line strength maps for abou…
