... 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. ...

... 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. ...

... Gravitational wave search provides insights into galaxy evolution and mergers . ... Research illuminates the shape of dark matter's distribution . ... An international team of researchers from Japan, Taiwan, and the United Kingdom has provided the first direct and clear evidence for an extremely flattened shape of dark matter's distribution in massive clusters of galaxies, a finding that confirms a major prediction of the prevailing dark matter model. ... Dark matter is "dark" in a couple of ways. ...

Figure 1 shows a detailed view of the IRAS4A outflow through the comparison between the H 2 O emission and the emission from several other molecular tracers of gas with different excitation conditions: H 2 , CO(3-2), CO(14-13), and CO(6-5). The figure nicely reveals where shocks deposit energy into the molecular cloud, lighting up the water emission along the outflow . ...
