SPECULATE: A synthetic spectral library, emulator and fitting package for accretion disc winds -- Infrastructure and application to CVs

Austen G. W. Wallis, Christian Knigge, James H. Matthews +6

Disc winds are critical components of accreting astrophysical systems and their observations can yield a wide variety of spectral line profiles. Yet, inferring disc wind parameters…

A nonrelativistic radiative transfer module for Idefix

Nicolas Scepi, Geoffroy Lesur

Radiation magnetohydrodynamic (RMHD) simulations are essential for comparisons with observations, particularly in the regime where fluids and radiation are dynamically coupled. Alt…

Radiation-ionization hydrodynamic simulations of AGN line-driven winds lead to transient shielding and BAL/UFO signatures

Nicolas Scepi, Christian Knigge, Amin Mosallanezhad +4

Disc winds from active galactic nuclei (AGN) can be launched by radiation pressure acting on spectral lines. However, launching a line-driven wind in the X-ray rich environment of…

The critical role of clumping in line-driven disc winds

Amin Mosallanezhad, Christian Knigge, Nicolas Scepi +4

Radiation pressure on spectral lines is a promising mechanism for powering disc winds from accreting white dwarfs (AWDs) and active galactic nuclei (AGN). However, in radiation-hyd…

Demystifying flux eruptions: Magnetic flux transport in magnetically arrested disks

Jonatan Jacquemin-Ide, Mitchell C. Begelman, Beverly Lowell +3

Magnetically arrested disks (MADs) are a compelling model for explaining variability in low-luminosity active galactic nuclei (AGN), including horizon-scale outbursts like those ob…

Monte-Carlo radiation hydrodynamic simulations of line-driven disc winds: relaxing the isothermal approximation

Amin Mosallanezhad, Christian Knigge, Nicolas Scepi +4

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 s…
