The effect of rotation on the thermal instability of stratified galactic atmospheres - II. The formation of High Velocity Clouds
Mattia Sormani, Emanuele Sobacchi
Whether High Velocity Clouds (HVCs) can form by condensation of the hot () Galactic corona as a consequence of thermal instabilities has been controversial.…
The effect of rotation on the thermal instability of stratified galactic atmospheres - I. Local analysis
Emanuele Sobacchi, Mattia Sormani
Observations show that (i) multiple gas phases can coexist in the atmospheres of galaxies and clusters; (ii) these atmospheres may be significantly rotating in the inner parts, wit…
On the magnetisation and the radiative efficiency of BL Lac jets
E. Sobacchi, Y. E. Lyubarsky
Theoretical modelling and observations of AGN jets suggest that the non-thermal electrons emitting the observed radiation should (i) carry an amount of energy comparable to the mag…
External Confinement and Surface Modes in Magnetised Force-Free Jets
E. Sobacchi, Y. E. Lyubarsky
In the paradigm of magnetic launching of astrophysical jets, instabilities in the MHD flow are a good candidate to convert the Poynting flux into the kinetic energy of the plasma.…
A model for periodic blazars
Emanuele Sobacchi, Mattia C. Sormani, Antonio Stamerra
We describe a scenario to explain blazar periodicities with timescales of few years. The scenario is based on a binary super-massive black hole (SMBH) system in which one of…
21-cm signatures of residual HI inside cosmic HII regions during reionization
C. A. Watkinson, A. Mesinger, J. R. Pritchard +1
We investigate the impact of sinks of ionizing radiation on the reionization-era 21-cm signal, focusing on 1-point statistics. We consider sinks in both the intergalactic medium an…
