The origin of the hot metal-poor gas in NGC 1291. Testing the hypothesis of gas dynamics as the cause of the gas heating
In this paper we test the idea that the low-metallicity hot gas in the centre of NGC 1291 is heated via a dynamical process. In this scenario, the gas from the outer gas-rich ring loses energy through bar-driven shocks and falls to the centre. Heating of
