About this book

This thesis describes the application of state-of-the-art high-energy X-ray studies to the astronomical quest for understanding obscured active galactic nuclei (AGN). These AGN are supermassive black holes growing by accretion of matter located in the nuclei of galaxies. The material that feeds these black holes also obscures them from view, rendering them challenging to study. It is possible to study them by effectively 'X-raying' galactic nuclei to peer through these obscuring veils. Beginning with the proof-of-concept application of novel X-ray Monte Carlo codes to the Nuclear Spectroscopic Telescope ARray (NuSTAR) spectrum of a known heavily obscured AGN, the thesis establishes the relevant parameters that characterise the AGN spectrum and central black hole growth rate. Next the largest sample of known heavily obscured AGN is compiled, finding the strength of a prominent iron spectral feature to weaken with AGN power. This is puzzling, and suggests that there may be more hidden AGN than previously thought. Finally by combining an all-sky infrared selection with NuSTAR follow-up, new heavily obscured AGN are identified. Obscuration emits infrared radiation, meaning that the infrared-selected AGN catalogue should be representative of the underlying AGN population. The absence of such representative catalogues has continually plagued cosmological studies, and the resultant obscured AGN fraction will be strongly constraining for AGN models. 

About the authors

Peter Boorman graduated with a 1st class honours degree in physics from the University of Southampton in 2015, finishing top of his cohort. His work during his PhD led him to a NASA press release, 2 refereed first-author papers, and 10 other co-authored papers. He was selected in 2019 for the annual Lindau Nobel Laureate meeting, representing the University of Southampton in a global gathering of Nobel laureates and the world's top young researchers. He now works at the Astronomical Institute of the Czech Academy of Sciences, and will soon start a fellowship at the University of Kyoto with a world-leading X-ray astronomy group.
