To infinity and beyond: space, stars & the universe
All systems go for 2009 installment of astro-themed Mini-Science public lecture series
In celebration of 400 years of astronomy, Â鶹AV’s Faculty of Science will launch its third edition of the wildly popular Mini-Science public lecture series on April 1. The United Nations has proclaimed 2009 the International Year of Astronomy in commemoration of the first astronomical use of the telescope in 1609 – hence this year’s focus on cosmology and space exploration. The seven-lecture lineup includes some of the University’s top professors – and, for the first time, a Canadian astronaut – who will offer mini-courses on the latest in space exploration.
The Mini-Science series will run every Wednesday until May 13. Here is this year’s speaker schedule:
Neutron Stars: Lighthouses of the Cosmos (Apr. 1)
Prof. Victoria M. Kaspi, Dept. of Physics
A renowned astrophysicist, Prof. Kaspi sheds light on cosmic
mysteries and has built an academic program from scratch. Her
research is in astrophysics – specifically on an exotic type of
star called a pulsar. Along with her research team, she uses “the
world's largest telescopes, both ground- and space-based, to study
these amazing objects.â€
An Astronomer's Window on the Birth of the Universe
(Apr. 8)
Prof. Matt Dobbs, Dept. of Physics
Prof. Dobbs’s research aims to improve our understanding of the
fundamental constituents of the universe – including its origin,
history, and fate – as well as to provide new insight into the
early universe, where the laws of particle physics and cosmology
intersect. His research group at Â鶹AV is building novel
instrumentation and experiments to explore the early universe with
wavelength observations of Cosmic Microwave Background (CMB)
radiation.
Island Universes: The Nature and Origin of Galaxies
(Apr. 15)
Prof. Tracy Webb, Dept. of Physics
Prof. Webb’s research centres on the growth of structure in the
universe, and galaxies in particular. She uses data at many
different wavelengths of light; each wavelength probes a different
physical process and tells us something unique about galaxy
formation. Prof. Webb studies mainly galaxies in the very distant
and young universe (i.e., high-redshift); because of the finite
speed of light we are seeing these systems as they existed 5-12
billion years ago and can literally watch them form. However, she
is also beginning programs to study nearby galaxies, since these
systems can be studied in much more detail and will provide insight
into the processes that formed the galaxies of today.
In Search of New Worlds: The Discovery and
Characterization of Exoplanets (Apr. 22)
Prof. Andrew Cumming, Dept. of Physics
Prof. Cumming studies the physics of compact objects and extrasolar
planets. He received his PhD in Physics from the University of
California, Berkeley, in December 2000, where he worked with Lars
Bildsten. He then spent a year as a postdoc at the Kavli Institute
for Theoretical Physics (KITP) in Santa Barbara, before moving to
the University of California, Santa Cruz as a Hubble Fellow. Prof.
Cumming joined the Â鶹AV Department of Physics in September 2004.
He has been a Scholar of the Canadian Institute for Advanced
Research (CIFAR) Cosmology and Gravity program since 2004, and was
awarded an Alfred P. Sloan Research Fellowship in 2006.
...in a Galaxy Far, Far Away: Measuring the Size of the
Universe (Apr. 29)
Prof. Bob Rutledge, Dept. of Physics
Prof. Rutledge was on a team of Â鶹AV and Penn State
University astronomers that discovered what is possibly the closest
neutron star using NASA's Swift satellite. If confirmed, it would
also be only the eighth so-called isolated neutron star ever
discovered. He works primarily in observational high-energy
astrophysics, studying the behaviour of neutron stars and black
holes.
Up or Down – The Body's Plasticity in Exploring Inner
and Outer Space (May 6)
Dr. Dave Williams, Â鶹AV alumni, retired Canadian Space Agency
astronaut, Director McMaster Centre for Medical
Robotics
Dr. Dave Williams is the only Canadian to have lived and worked
both in space and in the ocean. In 1992, he was selected by the
Canadian Space Agency to train as an astronaut; and in 2001 he
became an aquanaut through his participation in the joint NASA-NOAA
(National Oceanic and Atmospheric Administration) NEEMO 1 mission.
His first trip into space was aboard the Columbia space shuttle in
1998. In 2006, he was the crew commander of NEEMO 9 on a mission
dedicated to assess new ways to deliver medical care to a remote
location, as would be done during a long space flight. In 2007, he
served as a NASA mission specialist on STS-118 on the space shuttle
Endeavour where he took part in three of four spacewalks, the most
spacewalks performed in a single mission.
Exploring Mars on Earth: The Arctic as an Analogue for
Mars (May 13)
Prof. Wayne Pollard, Dept. of Geography
Prof. Pollard’s primary research activities concern the
investigation of the nature and origin of massive ground ice in the
Canadian High Arctic and in the McMurdo Dry Valleys region of
Antarctica, its role in landscape evolution and an assessment of
its response to global warming. An area of Prof. Pollard's research
examines polar environments as planetary analogues. Through
collaborations with NASA and CSA an important part of this research
is the application of various permafrost and hydrologic systems as
analogues for similar systems on Mars and the moons of Saturn and
Jupiter.
Registration is now open and is on a first-come, first served
basis.
