Nuclear rings are the inner edge of a gap around the Lindblad Resonance
Mattia C. Sormani, Emanuele Sobacchi, Jason L. Sanders
Gaseous nuclear rings are large-scale coherent structures commonly found at the centres of barred galaxies. We propose that they are an accumulation of gas at the inner edge of an…
Kinetic Simulations of the Filamentation Instability in Pair Plasmas
Masanori Iwamoto, Emanuele Sobacchi, Lorenzo Sironi
The nonlinear interaction between electromagnetic waves and plasmas attracts significant attention in astrophysics because it can affect the propagation of Fast Radio Bursts (FRBs)…
Ultrafast Variability in AGN Jets: Intermittency and Lighthouse Effect
Emanuele Sobacchi, Tsvi Piran, Luca Comisso
Gamma-ray flares from Active Galactic Nuclei (AGN) show substantial variability on ultrafast timescales (i.e. shorter than the light crossing time of the AGN's supermassive black h…
