... Tidal influence on each of the galaxies in our sample is quantified by identifying and measuring the distance to the nearest companion, using a photometric technique with good completeness characteristics. ... Massnormalised starformation rates were derived using galaxy stellar masses estimated from zband luminosities Nearest companions were identified using the algorithm illustrated in Figure 1. ... Some of the lowredshift galaxies in our sample with close companions are illustrated in Figure 3. ...

Next: The APM selected sample Up: Second priority candidates Previous: Second priority candidates . From the random selected subsample of second priority candidates we observed twenty six objects during the 6-m telescope runs (mainly those with R.A.< 11 h ) along with the observations of first priority targets. Altogether we found 12 emission-line objects: one appeared to be a QSO with z =3.15, and the rest are various types of ELGs. ... One object is an absorption-line galaxy. ...

... The visibility datasets possibly contain correlations for different polarizations and Stokes parameters. There are two basic ways that polarization characteristics can be measured: firstly, two orthogonal feeds can be present on the antennas, and the four different polarization correlations from a baseline can be taken and recorded. ... There are two ways the user can determine which polarizations he or she wants to process, either with the select parameter, or with the stokes parameter. ...

... The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...
