1. A New Database of Observed Spectral Energy Distributions of Nearby Starburst
We present a database of UV-to-FIR data of 83 nearby starburst galaxies. ... The NIR data are from new observations obtained at the NASA/IRTF and the Mount Laguna Observatory, combined with the published results from observations at the Kitt Peak National Observatory. ... In conjunction with IRAS and ISO FIR flux densities, all these data form a set of observed spectral energy distributions (SEDs) of the nuclear regions of nearby starburst galaxies. ...

3. The Circinus Galaxy
... Circinus is a nearby spiral galaxy only 4 degrees below the Galactic plane. ... Jones et al. (1996, in prep.) and Koribalski Whiteoak (1996) only recently mapped Circinus with several configurations of the ATCA; a few preliminary results are presented here. ... The elongated central disk (length about 5 arcmin) indicates a bar, and the central `hole' is caused by HI absorption against the bright central region of Circinus. ...

4. Some statistical trends and distributions
... Our resulting sample of ELGs presented in Tables 2 and 3 is not artificially biased to any specific type of galaxies. ... Since we are looking for selection of a sample of Case BCGs, it is interesting to examine how the detected BCGs are connected with Case emission-line codes. ... Altogether BCGs comprise about 60 % of all Case ELGs which display emission lines in our spectra, or about 44 % of all Case galaxies with some emission-line code. ... Among those with the code ``w'' about 40 % are BCGs. ...

5. Measurement of the dark halo shape in polar ring galaxies
... According to the most popular cosmological paradigm, the greater part of the galaxy mass is accumulated in the dark matter halo. ... The polar ring galaxies (PRGs) reveal external rings or disks of gas, dust and stars rotating in a plane roughly perpendicular to the disk of the central galaxy. ... The shape of the dark halo in the model was chosen so as to achieve the best fit to the observed rotation of both galaxies themselves and their polar rings. ... The SPRC-7 galaxy. ...

. The relation between ellipticity and size. Red data points are the observed data; most of them have elongated shapes, and larger galaxies tend to have larger ellipticities. Gray-colored regions represent the probability distributions calculated with the computer simulations, in which two galaxies are located at so close distance that they are blended as an elongated galaxy, as shown in the right pictures schematically.
