The spectral energy distributions (SEDs) of galaxies are shaped by nearly every physical
property of the system, including the star-formation history, metal content, abundance …

Observations of galaxy isophotes, long-slit kinematics, and high-resolution photometry
suggested a possible dichotomy between two distinct classes of elliptical galaxies. But these …

We review the formation and evolution of fossil groups and clusters from both the theoretical
and the observational points of view. In the optical band, these systems are dominated by …

The integrated spectra of stellar systems contain a wealth of information, and its analysis can
reveal fundamental parameters such as metallicity, age, and star formation history. Widely …

We present the HINOTORI (Star Formation History Investigation To Find Rejuvenation)
project to reveal the nature of rejuvenation galaxies (RGs), which are galaxies that restarted …

We constructed an oxygen abundance map and N/O ratio map of the unusually low
excitation dwarf irregular galaxy NGC 4163 based on publicly available spectroscopy …

We present a study for a sample of galaxies with active nuclei to characterize the main type
of PAH molecules present in these objects and the local physical conditions of their …

In this thesis, we use the ProSpect code to push the boundaries of what is possible with
spectral energy distribution (SED) fitting. This includes consistent treatment of galaxies …

Abstract By using Data Analysis Pipeline (DAP) products of Mapping Nearby Galaxies at
Apache Point Observatory (MaNGA), which are publicly available from the SDSS Data …

We aim to understand the properties at the locations of supernova (SN) explosions in their
host galaxies and compare with the global properties of these host galaxies. We use the …
