Spectral Properties of Some IRAS Starburst Galaxies at HI 21-cm statistic study

Abstract

AbstractMany research deal with physical properties of HI gas in all types ofgalaxies.The 21cm data analysis allows to measure spectral and radioproperties for galaxies, so it allows to study physical operation that assistant instarformation. We interest here with 100 galaxy known as Starburst galaxiesand made the statistical treatment on all data to study the optical propertiesand find the correlations between these data , but in general , this type haveUV- radiation doesn't differ with other types that haven't this radiation in starformation properties just in sub-different.
