The general theme of the Black Hole group at IAG USP is black hole physics which touches on a wide variety of implications and broadly encompasses the understanding of the accretion flows that surround black holes, the outflows they produce, and how supermassive black holes impact their host galaxies. More specifically, the Black Hole Group is working on the following list of science topics:
Numerical simulations of black hole accretion and outflows
• Radiatively inefficient accretion flows in curved spacetimes
• Sub-relativistic winds: triggering near the black hole, AGN feedback
• Production of relativistic jets (Blandford-Znajek and Penrose process)
• Radiation signatures from accretion and outflows
Analysis and modeling of multiwavelength and multimessenger observations of supermassive black holes
• Radio to gamma-rays spectral energy distributions (jet and disk)
• Broad emission lines from accretion disks
• 🆕 Neutrinos and cosmic ray production
• Sources: Low-luminosity AGNs, radio galaxies, quasars
Gamma-ray astronomy with Fermi LAT
• Analysis of LAT observations using ScienceTools
• Variability of blazar and non-blazar populations
Connections between stellar and supermassive black holes
• Search for universalities in jet and accretion properties of black holes across the mass scale
Observational and theoretical prospects for the Cherenkov Telescope Array (CTA), Event Horizon Telescope, GMT, JWST and LSST
• Preparations for future CTA observations: simulations, extrapolations from LAT results
• Theoretical prospects for Event Horizon Observations: near-horizon physics and radiation
• Expected synergies between LSST and Fermi LAT
High-performance computing (HPC) and scientific applications
• GPU acceleration
• Heterogeneous computing applications of high-performance computing (HPC)
• Deep learning applied to (astro)physics
