We present a detailed model based analysis of spheroidal galaxies with prominent dust lanes (DLSGs) using the data released from some of most important all sky multiwavelength surveys (FIRST, IRAS, SDSS and GALEX). We use data of sample of 362 DLSGs, ranging from redshifts of z = 0.01 to 0.07 to fit the spectral energy distribution (SED) using CIGALE. CIGALE, a code developed by Laboratoire d’Astrophysique de Marseille, is a best tool to derive the properties of galaxies by fitting SEDs of galaxies from the rest frame far UV to far IR wavelength. Using bayesian analysis the code determines parameters such as mass of the galaxy, D4000 break, bolometric luminosity, dust luminosity, ages of young, old stellar population, star formation rate, dust attenuation. Analysis of the SEDs of the galaxies should therefore, in principle, allow us to completely understand the properties of DSLGs. |
