INAF OAS

I am a permanent Researcher at the INAF Astrophysics and Space Science Observatory. I have been working for over a decade mainly in the field of Theoretical and Computational Astrophysics focusing on the formation and evolution of galaxies and groups/clusters of galaxies, and the co-evolution of supermassive black holes. I love to study the astrophysics of active galactic nuclei (AGN) feeding/feedback, diffuse plasmas, and multiphase gas. I primarily develop and carry out 3D high-resolution MHD simulations with massively parallel supercomputers (>10k cores), and use first-principle simulations as controlled astrophysical experiments to understand a large range of multiwavelength observations (X-ray, optical/IR, radio), while constructing and probing new quantitative physical models.

Research Activity

  α  Theoretical & Numerical Astrophysics: formation and evolution of galaxies, groups, clusters.

  β  Astrophysics of (supermassive) black holes and accreting objects.

  γ  Multiphase gas astrophysics: instabilities, warm filaments, molecular clouds, dust, metals.

  δ  AGN feedback (jets, outflows, radiation) versus cooling flows and star formation.

  ε  Astrophysical plasmas (ICM, IGrM, CGM/ISM): MHD, turbulence, conduction, shocks.

  ζ  Quantiative comparison with multiwavelength observations (X-ray, optical/IR, radio).

​

Research Methods

  η  High-resolution 3D magneto-hydrodynamic simulations.

  θ  Independent developer of several physical and numerical modules (e.g., for FLASH).

  κ  Adaptive mesh refinement and cloud-in-cell particles (dark matter, stars, BHs).

  λ  Massive parallelization and optimization for HPC supercomputers (e.g., NASA Pleiades).
