Simulating Lyman-alpha Emitters

Last updated on May 2, 2020

Below plots show first results of our new radiative transfer code for meshless structures applied to individual halos in the IllustrisTNG simulations.

Lyman-alpha emitter after radiative transfer. Surface brightness in erg/s/cm$^2$/arcsec$^2$.

Lyman-alpha emitter after radiative transfer. Artificially lowered neutral hydrogen density by a factor of $10$, revealing the radiative transfer smoothing out the emission from the star forming regions. Surface brightness in erg/s/cm$^2$/arcsec$^2$.

The neutral hydrogen column density responsible for scattering out the injected photons in star forming regions.

My research interests include cosmoslogical galaxy formation simulations, Lyman-$\alpha$ radiation to study galaxies and the large-scale structure, supernovae type Ia and high-performance computing.
