Dust lane spheroidal galaxies (DLSGs) show peculiar lanes of dense obscuring interstellar dust against their background, which are remnants of recent mergers. The main goal of this work is to use data spanning UV to IR from Galaxy Evolution Explorer (GALEX GR7), Sloan Digital Sky Survey (SDSS DR12), Wide-field Infrared Survey Explorer (WISE), Two Micron All-Sky Survey (2MASS) and Infrared Astronomical Satellite (IRAS) surveys to explore the different physical parameters of DLSGs in the nearby universe. Our sample consists of 280 DLSGs for which we have calculated their stellar mass, star formation rate (SFR), dust mass and other related parameters. We use relations from literature to calculate the parameters and compare with the results from SDSS template fitting method. We will be further looking into more galactic parameters and the correlations between them. |
