/31/ The Millennium Simulation

This episode is a conversation with Volker Springel about the Millenium Simulation, which at the time was the largest simulation of the growth of cosmic structure, including a detailed model for the formation of galaxies and supermassive black holes. In the episode we talk about the physical/cosmological background, the simulation process and approach as well as some details about the hard- and software.

 

/18/ Astrobiology at the NASA Astrobiology Institute

This episode is a conversation with Dr. Carl Pilcher, the director of the NASA Astrobiology Insititute at NASA Ames Research Center. The conversation comes in two parts. Part one covers the conceptual basics of astrobiology and life: what is life, what are the preconditions for life to exist, how to recognize it, etc. Part two looks at the process of trying to find places in the universe that could host life, primarily astronomical observations and missions to other planets.

 

/16/ Radio Astronomy and the ALMA Telescope

This episode is a discussion about radio astronomy and the ALMA observatory with ESO’s Robert Laing, the European instrument scientist for ALMA. The episode has three parts. The first part talks about the science of radio astronomy: current challenges and physical basics. The second part adresses how observing with radio astronomy actually works: the principles behind telescopes and how they are built and operated. Part three then looks at the ALMA observatory specifically, a new, large sub-millimeter radio interferometer currently built in the Atacama Desert in Chile.
