Project Description

Correlated continuum and broad emission line variability studies have proven a powerful probe of the central regions of Active Galactic Nuclei (AGN).

Traditionally RM has focused on probing the spatial distribution and kinematics of the broad emission line region (BLR), and determining
the mass of the central supermassive black hole. More recently, correlated continuum variations have been used to : (i) measure the
distance to the hot dust (dust RM), and (ii) map the disc radial temperature profile, T(R). Dust delays provide an upper limit to the BLR outer boundary necessary for constraining photoionization models, while T(R) can be used to determine the mass accretion rate through the disc for AGN with known black hole mass.

We have on-going optical--IR programs with Liverpool Telescope in support of HST and Swift/XRT/UVOT monitoring programs, providing
ground-based spectrophotometry, for disc, dust and broad emission-line variability studies. PhD projects will centre around data reduction and analysis, and may include a substantial modelling component.

Funding Notes

This project is eligible for a fully funded STFC studentship which includes :
· A full UK/EU fee waiver for 3.5 years
· An annual tax free stipend of £14,777 (2018/19)
· Research Training Support Grant (RTSG)
· Conference Fees & UK Fieldwork

Studentships are available to UK/EU applicants who meet the STFC Residency Criteria; if you have been ordinarily resident in the UK for three years you will normally be entitled to apply for a full studentship.
