The Transient Radio Sky
The high time-resolution radio sky represents unexplored astronomical territory. This thesis presents a study of the transient radio sky, focussing on millisecond scales. As such, the work is concerned primarily with neutron stars. In particular this research concentrates on a recently identified group of neutron stars, known as RRATs, which exhibit radio bursts every few minutes to every few hours. After analysing neutron star birthrates, a re-analysis of the Parkes Multibeam Pulsar Survey is described which has resulted in the discovery of 19 new transient radio sources. Of these, 12 have been seen to repeat and a follow-up campaign of observations has been undertaken. These studies have greatly increased our knowledge of the rotational properties of RRATs and enable us to conclude that they are pulsars with extreme nulling and/or pulse-to-pulse modulation. Although the evolution of neutron stars post-supernova is not yet understood, it seems that RRATs fit into the emerging picture in which pulsar magnetospheres switch between stable configurations.
The New Despotism
An Australian Book Review Best Book of the Year A disturbing in-depth exposé of the antidemocratic practices of despotic governments now sweeping the world. One day they’ll be like us. That was once the West’s complacent and self-regarding assumption about countries emerging from poverty, imperial rule, or communism. But many have hardened into something very different from liberal democracy: what the eminent political thinker John Keane describes as a new form of despotism. And one day, he warns, we may be more like them. Drawing on extensive travels, interviews, and a lifetime of thinking about democracy and its enemies, Keane shows how governments from Russia and China through Centra...
