Corrugated velocity patterns in the spiral galaxies : NGC 278 , NGC 1058 , NGC 2500 & UGC 3574
We address the study of the Hα vertical velocity field in a sample of four nearly face-on galaxies using long slit spectroscopy taken with the ISIS spectrograph attached to the WHT at the Roque de los Muchachos Observatory (Spain). The spatial structure of the velocity vertical component shows a radial corrugated pattern with spatial scales higher or within the order of one kiloparsec. The gas ...
متن کاملThe Scale Height of NGC 1058 Measured from its HI Power Spectrum
We have measured the HI power spectrum of the nearly face-on spiral galaxy NGC 1058 from radio-interferometric observations using a visibility based estimator. The power spectrum is well fitted by two different power laws P (U) = AUα, one with α = − 2.5± 0.6 at small length-scales (600 pc to 1.5 kpc) and another with α = − 1.0± 0.2 at large length-scales (1.5 kpc to 10.0 kpc). We interpret this...
متن کاملLarge scale star formation in galaxies . I . The spirals NGC 7217 , NGC 1058 and UGC 12732 Young Star Groupings in Spirals
We present multiband photometric observations of three spiral galaxies selected in a sample suited for the study of young stellar groupings and their relationship with the parent galaxy and the galactic environment. Star forming regions have been identified using an objective technique based on a multivariate statistical analysis. Maps of young star groupings are given for each galaxy. The lumi...

The knowledge that melanoma is susceptible to attack by the host’s immune Abstract system has resulted in the testing of a variety of immunotherapies. Interferon-α-2b, which has several anti-tumour mechanisms including an antiproliferative effect, an anti-angiogenesis effect, the enhancement of natural-killer cell activity and the upregulation of tumour antigen presentation, has shown tremendou...
