... We have mapped the 21-cm absorption in the nuclear region of the starburst galaxy NGC 1808 using the VLA AnB-hybrid array with a resolution of approx. 5.2" (= 275 pc). ... The velocity center of the absorption changes from about +120 km/s relative to the systemic velocity in the NW to -145 km/s in the SE, following the rotation pattern in the outer regions of the galaxy. ... The gravitational mass required to explain this fast rotation in the center of NGC 1808 is a few times 10^9 solar masses. ...

... A detailed study of NGC 3582 , also known as NGC 3584 and NGC 3576 , uncovered at least 33 massive stars in the end stages of formation, and the clear presence of the complex carbon molecules known as polycyclic aromatic hydrocarbons (PAHs). PAHs are thought to be created in the cooling gas of star forming region s, and their development in the Sun's formation nebula five billion years ago may have been an important step in the development of life on Earth. ...

... An analysis on new observational data taken with the MPFS and SCORPIO spectrographs indicates that we are dealing with the "galactic wind": the gas is blown above the galactic plane with the characteristic velocity of about 130km/s. The gas outflow is caused by a combined action of winds from the supernovae and young massive stars located in the galaxy's circumnuclear region. ... The most probable hypothesis is that the accretion of intergalactic gas clouds is feeding their star formation. ...

... It was shown in the early 1980's that spectral lines formed around 1-2.5 x 10 5 K were enhanced in radiance by factors up to 15-25 over the normal quiet Sun.
