Star formationIsolated Galaxies Compact Groups Hα study of a redshift-limited subsampleHα is a good tracer of recent star formation in places where extinction is not high. The aims of our study are :
Our Hα sample is composed of 224 galaxies with 1500 Kms-1 ≤ VR ≤ 5000 Kms-1 and morphologies S0/a or later. The 224 galaxies comprising our sample for star formation studies, have been imaged in Hα and Gunn r filters, in order to trace respectively the regions ionised by newly born stars (HII regions) and the older stellar component. The data were obtained at the Observatorio de Sierra Nevada, CAHA, EOCA, JTK and San Pedro Mártir. (Bergond et al. in prep) |
