Polarised X-ray Reflection: Creating polarised XILLVER tables

The results from recent IXPE have been suggestive that the X-rays reflected off accretion discs form an important contribution to the polarisation spectrum seen from accreting systems. I will discuss the latest work in creating X-ray reflection models that include polarisation through the addition of the spectra of Stokes parameters, using the XILLVER X-ray radiative transfer code. This code has already produced many (unpolarised) X-ray tables, which include detailed atomic features and are regularly used in the community. I will present this work in both the context of the semi-analytical calculations of Chandrasekhar (1960), and also the observations of accretion discs by IXPE over the last few years.
