Shingo Hirano

I am an astronomer working on star formation and computational astrophysics, with a focus on first stars, first galaxies, and black-hole seeds in the early Universe.

Future Research Directions

My near-term goal is to build a unified framework for the origins of elements, disk-forming environments, and high-redshift black holes. I focus on connecting first-principles simulations with population-level predictions and observable diagnostics.

Planned Research Themes

1. Metallicity-dependent star formation theory
   I will develop a unified model across zero-, low-, and solar-metallicity regimes, including chemistry, cooling, angular momentum transport, and magnetic effects.

2. First-galaxy formation and fossil records
   Using cosmological simulations, I will quantify how environment-dependent first-star formation shapes first galaxies and their descendants, including observable imprints in Milky Way metal-poor stars.

3. Formation pathways of high-redshift black holes
   I will test multiple seed-formation channels and predict their growth, host-galaxy properties, and observables relevant to quasars and Little Red Dot candidates.

For Students and Collaborators

I welcome students and collaborators interested in:

• numerical studies of early structure formation and star formation
• MHD/radiation-hydrodynamics across metallicity regimes
• theory-observation connections for high-redshift galaxies and black holes
