The nature of dark matter
Using cosmological hydrodynamical simulations, I study galaxy formation in several popular alternative dark matter models:
A broad range of systems have been studied:
- Ultra-small and compact substructures (miniclusters)
- Low-mass dwarf galaxies in the Local Group (MW & M31)
- Bright "isolated" dwarf galaxies in the field
- Massive, dynamically-relaxed galaxy clusters
- Galaxies in the early Universe
Using the data from the IllustrisTNG simulation and the SKIRT dust radiative transfer code, I have generated an array of mock observables for simulated galaxies at high redshift. The data product includes far-UV to far-IR SEDs, photometry in JWST NIRCam and MIRI bands, and high-resolution optical spectrum (with emission line measurements and spectral indices). The same technique has been applied to the THESAN re-ionization simulation and will be applied for galaxy merger identification for JWST observations in near future.

In my first year, I have developed a model for the evolution of bolometric quasar luminosity functions based on a large compilation of multi-band observations. I have also explored the scenario of SMBH seeding with dissipative self-interacting dark matter. For more information about related projects.
