Stellar Population Synthesis

We use advanced spectroscopic and photometric techniques to derive detailed physical and chemical properties of stellar systems across different galaxy types. Our work builds panchromatic reference databases and applies high-resolution spectroscopic analysis to unravel the star formation and chemical enrichment histories encoded in the integrated light of stellar populations.

Surface Brightness Fluctuations as Stellar Population Diagnostics

Surface brightness fluctuations (SBF) provide a powerful distance-independent probe of the underlying stellar content of galaxies. We calibrate SBF amplitudes against population synthesis models to simultaneously constrain ages, metallicities, and stellar mass functions in early-type galaxies across a range of environments.

Stellar Populations in the Fornax Cluster

Using multi-band photometry from the Next Generation Fornax Survey, we characterise the resolved and unresolved stellar populations of galaxies across the Fornax cluster. By fitting spectral energy distributions to individual point sources and diffuse light, we map the spatial distribution of ages and metallicities within cluster galaxies.
