Erin Boettcher, Graduate Student, Department of Astronomy, UW-Madison, discusses cosmic rays, their characteristic properties and how we can detect them from Earth. Cosmic rays can be used as probes to understand the physical conditions in other galaxies.
Karen Lewis, Assistant Professor, Department of Physics, College of Wooster OH, studies x-rays to find the presence of Active Galactic Nucleus (AGN)—a super-massive black hole at the center of a galaxy. Lewis explains how to pick out the AGN from the rest of the universe’s x-ray sources.
Aleks Diamond-Stanic, Postdoctoral Fellow, Department of Astronomy, UW-Madison, discusses the importance of cosmic fuel, or the supply of gas within the galaxies, in the creation of star formation.
Eric Wilcots, Professor, Department of Astronomy, UW-Madison, discusses the collaborative effort, which includes University of Wisconsin astronomers, to build the world’s largest radio telescope. The telescope will have a collecting area equal to one square kilometer, making it the most sensitive radio detector in the world.
Simon Gilroy, Professor, Department of Botany, UW-Madison, explores whether plants and microbes could provide food during a long spaceflight or in a colony on Mars. Gilroy discusses how a lack of gravity affects plants and humans.
Benedikt Riedel, Graduate Research Assistant, Department of Physics, UW-Madison, discusses researching supernovae, also known as exploding stars, at the IceCube Observatory at the South Pole.
Andrew Schechtman-Rook, Graduate Student, Department of Astronomy, UW-Madison, explains advanced modeling techniques and high-resolution near-infrared imaging to study the anatomy of other galaxies and compares them to our own. Mapping this structure is essential to understanding how spiral galaxies form and evolve.
Britt Lundgren, a Postdoctoral Fellow in the Department of Astronomy, UW-Madison, explains how quasars can be used as probes in the vast intergalactic distances they cross. Lundgren explores how astronomers use this information to map the “cosmic web” of matter that shapes our visible universe.
Cami Collins, Research Assistant, Department of Physics, UW-Madison, asks how stars and planets form and why some black holes are the brightest objects in the universe. Collins discusses the underlying physical mechanism which could reveal the answers.
Eric Hooper, Scientific Staff, Department of Astronomy, UW-Madison, explains the types of instruments astronomers use at observatories and the advantages of looking into space from different vantage points around the globe. Hooper discusses the research University of Wisconsin astronomers are working on at observatories all over the world.
