Propositions
accompanying the dissertationThrough a lens darkly: magnified views of massive galaxy formation
1. Surveys of gravitationally lensed sources can efficiently probe faint emission from populations at cosmologically interesting redshifts (Chapters 2 and 3). 2. High-resolution observations of gravitational lens systems can efficiently ac-cess the small physical scales required to test mechanisms of galaxy formation and evolution (Chapters 4, 5 and 6).
3. High-redshift quasar hosts are or were dusty star-forming galaxies (Chapters 2, 3 and 4).
4. Selecting galaxies on their AGN properties is a novel method to select dusty star-forming galaxies with different observational biases (Chapter 4). 5. Sub-mm interferometry has opened new possibilities to probe low-mass
structures (106to1010M¯) and test cosmological models with gravitational
lensing (Chapter 5).
6. The development of ‘science-ready’ data sets cannot circumvent the knowl-edge and skills required to analyse and interpret interferometric data. 7. Astronomy research has little value to society unless it is disseminated
through education and outreach. Therefore, researchers have a moral obliga-tion to participate in disseminaobliga-tion.
8. The increasing dominance of internet culture in our lives has allowed us to house ourselves in a self-curated bubble that reinforces our own ideals and cognitive biases, while isolating us from the experience and opinions of others.
9. When you are in a position of power over others you should regularly con-sider your privilege, and your responsibilities to those more junior.
10. Diversity efforts by and large put the onus of effort on underrepresented groups: the gatekeepers of academic spaces often fail to be aware of their privilege or to take action to correct imbalances.
11. Non-traditional routes into academia should be encouraged.
