New spectral decomposition method for QSOs using IFU data.
Quasi-stellar
objects (QSO) are very luminous active galactic nuclei (AGN), which
have been explored broadly to understand the connection between AGN and
the host galaxy. However, despite the last decade's efforts, several
questions regarding this connection remain unanswered. This is mainly
because their study requires a robust deblending of the AGN and host
galaxy light.Integral
Field Spectroscopic (IFS) can resolve both the integrated and spatially
resolved spectroscopic properties of galaxies. Several techniques have
been developed for this purpose; however, their algorithms are complex
and require several steps. In this talk, I will present a novel,
straightforward technique for removing the AGN and revealing the host
galaxy's 3D information. This technique will be used for the scientific
preparation of the exploitation of the High Angular Resolution
Monolithic Optical and Near-infrared Integral field spectrograph
(HARMONI), which is the first light instrument of the Extremely Large
Telescope (ELT). Consequentially, I will also introduce the main
features of this instrument.
