Deciphering a gravitationally lensed system with the ESO-MUSE integral field spectrograph

Abstract

The quasar system 2M1134-2103 is analysed using ESO-MUSE integral field spectrograph. 2M1134-2103 is a quadruple lensed quasar and the dynamics of such a system are intriguing to study. Several properties have been studied and derived for the system but first, data reduction process of the MUSE pipeline is analysed and a sysnthesis is made for a future user. Next, the goal is to derive information about the system, so for that purpose a code is written in this work to extract the spectrum of the lensing galaxy as well as the spectra of the lensed quasar images. The redshift of the lensing galaxy was unknown at the beginning of this thesis and its estimated in this work, along with the redshift of the quasar and some galaxies in the FOV. The corresponding emissions and absorptions in the lensing galaxy and the quasar are studied and presented. The black hole mass of the system is also derived using scaling relations and the spectra of the quasar are analysed for microlensing using the MmD technique.
