DOI: 10.1093/mnras/staa1767

Abstract: Photoevaporation driven by high energy radiation from the central star plays an important role in the evolution of protoplanetary discs. Photoevaporative winds have been unambiguously detected through blue-shifted emission lines, but their detailed properties remain… read more here.

DOI: 10.1093/mnras/stab2214

Abstract: Growth of the black holes (BHs) from the seeds to supermassive BHs (SMBHs, $\sim \!10^9\, M_\odot$) is not understood, but the mass accretion must have played an important role. We performed 2D radiation hydrodynamics simulations… read more here.

DOI: 10.1093/mnras/staf1101

Abstract: Disc winds play a crucial role in many accreting astrophysical systems across all scales. In accreting white dwarfs (AWDs) and active galactic nuclei (AGN), radiation pressure on spectral lines is a promising wind-driving mechanism. However,… read more here.

DOI: 10.1093/mnras/staf805

Abstract: Hydrodynamic simulations of protoplanetary discs with planets typically assume that the disc is viscously driven, even though magnetic disc winds are now considered the primary driver of angular momentum transport through the disc. Magnetic disc… read more here.

DOI: 10.1093/mnrasl/sly204

Abstract: We report on the detection of a blueshifted Fe K absorption feature in two consecutive XMM–Newton  observations of the luminous blue quasar Ton 28, at the 4σ cumulative significance. The rest energy of 9.2 keV implies the presence… read more here.
