Title

PANCHROMATIC STUDY OF STELLAR AND DUST CONTENT OF EARLY TYPE GALAXIES UGC 9519 AND NGC 3699

Abstract

The progress in space technology over past few decades allows researcher to study target galaxies over a wide range of electromagnetic spectrum. In the present study we performed a multi-wavelength analysis of early type lenticular galaxies UGC 9519 and NGC 3699 using optical imaging, spectroscopy, stellar population synthesis and SED fitting. For this study we made use of SDSS data for imaging and spectroscopy. For SED fitting, over a range of UV-Optical- IR region, we used the photometric data by GALEX, SDSS, 2MASS, WISE and IRAS and the MAGPHYS code. The optical colour map of our target galaxies clearly indicates the presence of moderate amount of dust in it. The dust mass is found to be 4.54 × 105 and 7.82 × 107 Mʘ for UGC 9519 and NGC 3699 respectively. It is observed that, although the present galaxies are of “Red & Dead” class, it holds ongoing star formation activity with the star formation rate equal to 3.61 × 10-5 and 0.24 Mʘ/yr for UGC 9519 and NGC 3699 respectively.

Key Words

Galaxies, early type galaxies, star formation, interstellar dust, optical spectroscopy, SED fitting.
