The spectral-type/luminosity and the spectral type/satellite-density relations in the 2dFGRS
B. Kelm, P. Focardi, G. Sorrentino
We examine the relative fractions of passive (Type 1), quiet-SF (Type 2) and active-SF (Type 3+4) galaxies as a function of luminosity and number of neighbours in several volume li…
Active star-forming galaxies in pairs in the 2dF
G. Sorrentino, B. Kelm, P. Focardi
We explore the close environment of active star-forming galaxies (ASF) in the 2dF. We find ASF galaxies to be the most likely population to inhabit extremely close pairs located in…
Compact Groups in the UZC galaxy sample: II. Connections between morphology, luminosity and large-scale density
Kelm Birgit, Focardi Paola
The nature of Compact Groups (CGs) is investigated by comparing the luminosities and morphologies of CG galaxies, CG Neighbours and Isolated galaxies. CGs turn out to include more…
Compact groups in the UZC galaxy sample
Paola Focardi, Birgit Kelm
Applying an automatic neighbour search algorithm to the 3D UZC galaxy catalogue (Falco 1999) we have identified 291 compact groups (CGs) with redshifts between 1000 and 10000 km/s.…
Star Formation in Dwarf Irregular Galaxies: NGC 6822
G. Marconi, M. Tosi, L. Greggio +1
Our proposed method to study the star formation histories in nearby irregulars is here applied to NGC 6822. To this purpose we have obtained accurate CCD photometry of three region…
