... For the lack of good information on object sizes we joined under BCGs all the galaxies with HII-region spectrum type using Salzer's determination of BCG type as composed from HIIH, DHIIH and SS types. ...
... At the redshift of the host galaxy z=0.0054 (Virgo-flow corrected distance 29.6 Mpc) SN 1998bv is situated at 0.5 kpc (5'') from the central supercluster of currently forming massive stars, at the edge of the large HIIregion. ...
... We argue that SBS 0335-052W is a good candidate for a nearby, young dwarf galaxy. galaxies: abundances -- galaxies: irregular -- galaxies: photometry -- galaxies: evolution -- galaxies: formation -- galaxies: ISM -- HIIregions -- ISM: abundances . ...
... Introduction The Orion Nebula is an HIIregion on the near side of a giant molecular cloud, which contains one of the most prominent and nearby (D | ...
... into account the above mentioned relations between the galaxy disk parameters, we find that 3/2 S F R d(ng )/dt · R3 (ng )2 · R3 (Mg )2 /R Mg , i.e. obtain the known Kennicutt law, but for the galaxies themselves, not for individual HIIregions only ...
