摘要：
The environmental effects on galaxy evolution have recently been disputed based on large SDSS galaxy samples. However, these effects are still expected to be strong for low-mass galaxies. We obtained deep near-infrared imaging of irregular dwarfs in CenA, M81 and Sculptor groups - spanning a range of galaxy density, - and we study the properties of these dwarfs, i.e. abundances, and structural parameters. Here we report a preliminary assessment of the structural parameters for these galaxies.
