Indoor basketball has ended for another season. There is hope for renewal in the air because of the news that the outdoor basketball nets may get fixed this summer. Missing from photos are Els Peeters, Tamie Poepping, Chris Mokry, Jean-Baptiste Kikwaya, Steve Hudson, and Jamu Alford, and Carol Jones.
The representation of women on our faculty is by far the highest in Canada, with nine of the 29 faculty members in Physics and Astronomy at Western being women!
Women have long been under-represented in our field, and only about 10% of physics and astronomy faculty in North America are female. We are proud of our leadership in addressing this issue.

Undergraduate student Amanda Papadimos has uncovered two orbiting solar system bodies which may be part of a larger group orbiting between Jupiter and Neptune.
These so called Centaur Objects have received Primary Designation by the astronomical community. Objects with such a designation require longer term observations of their orbits in order to prove their status.
These discoveries were part of Amanda's Physics 491E project. The course is taught by Prof. Jan Cami. Amanda's advisor was Prof. Paul Wiegert.
You can see GIF animations of the discovery images for objects 2004VP112 and 2005UN524 below. Orbital information can be found at NASA's Jet Propulsion Laboratories Small Body Database Browser.
Dr. Randy Kissack riveted a full house audience with his historic journey back to the heady days of the X-15 experimental rocket aircraft. The pilots and planes of this program contributed many firsts to the field of hypersonic aviation and space aeronautics.
Randy will repeat this presentation at the next meeting of the London Centre of the R.A.S.C. This meeting will take place on Friday, April 18, at 7:00 p.m. in room B1073 (Building B) at Fanshawe College.
Physics and Astronomy had several displays at the March, 2008 Open House. Volunteers were CarolAnne Black, Adrienne Campbell, Peter Frank, Mark Gooyers, Michael Jensen, Roland Lendzian, Karen Mann, Phil McCausland, Patrick Whippey, Robin Wing, and Martin Zinke-Allmang.
In atmospheric dynamics, wave events play a major role in forcing the mean flow of the atmosphere, and this is particularly true in the upper atmosphere, above 60 km altitude.
Some of the strongest wave forcing anywhere on Earth occurs above Cape Horn, at the Southern tip of South America.
In an effort to study this extreme forcing, a new radar is being constructed at Rio Grande on the Island of Tierra del Fuego. It is the world's first meteor momentum flux radar, and measures the wave forcing at heights of 80 to 100 km above the Earth. It is being built by a consortium including Colorado Research Associates, The University of Western Ontario, and Bath University in the UK. Understanding momentum divergence and mean-wind-forcing are important at all levels of the atmosphere, not just the upper atmosphere, and is even important for forecasting in the troposphere where we live. But because the effects are more dramatic at the upper regions, the height regions of 80 to 100 km make an especially good place to study it.
Dr. Wayne Hocking's radar also is a component of a pole to pole network of meteor radars called axonmet.
The Sentinel array of all-sky cameras detected a large fireball on March 5. Shown here is the camera on Western's campus.
Meteor Physics researchers at Western used these images along with model calculations to predict that a meteorite or debris may have landed in the Parry Sound area.
The Government of Ontario and The University of Western Ontario announced that 9 million dollars has been allocated for Phase I of the renovation of the Physics and Astronomy Building. Construction is to begin in early 2009.

Dr. Eugene Wong of our department has been named the Ontario Researcher of the Month by the Canadian Cancer Society.
Physics and Astronomy students were in action at the 2008 Women In Science and the Department Of Mathematics (W.I.S.D.O.M.) open house held in the UCC building.

Observations with NASA's Spitzer Space Telescope of extended dust in normal Elliptical Galaxies provide a new confirmation of buoyant feedback outflow in the hot gas atmospheres around these galaxies. Both the heating by the supermassive black holes, and the buoyant removal of gas from the galaxy's center have the effect to reduce the likelihood of star formation.
UWO adjunct Physics and Astronomy professor Dr. Pasquale Temi, who shares his time with NASA Ames Research Center and the SETI Institute in California is the principal investigator of a Spitzer program aimed to investigate the far infrared dust emission from normal elliptical galaxies. The astronomical implicationsof the extended dust emission detected in some of these normal ellipticals are far-reaching and provide newinformation about energetic processes in galactic cores.

Prof. Wayne Hocking has had an article published in the international weekly science magazine Nature.
The article is entitled "Detection of stratospheric ozone intrusions by windprofiler radars", and is authored by W. K. Hocking, T. Carey-Smith, D. W. Tarasick, P. S. Argall, K. Strong, Y. Rochon, I. Zawadzki & P. A. Taylor.
Prof. Jan Cami, along with fellow astronomer Guy Perrin (Paris Observatory) and others, have taken highly detailed infrared observations of the famous supergiant star in Orion, Betelgeuse.
The observations show that Betelgeuse has a molecular layer outside of its atmosphere, which furthermore also contains alumina (Al2O3)dust particles.
The presence of these species explains some of the discrepancies between the measured sizes of supergiant stars and the sizes they ought to have according to theoretical stellar models.
Prof. Sarah Gallagher, an adjunct faculty member at Western, is a member of a group of astronomers who have made an important discovery as to a source of cosmic dust in the early universe.
New findings from NASA's Spitzer Space Telescope suggest that space dust -- the same stuff that makes up living creatures and planets -- was manufactured in large quantities in the winds of growing black holes in the early universe.

On Wedn. Oct. 3 a network of Ontario weather radar research sites was announced at a press gathering in Harrow.
The O-QNET network has involvement from York University, The University of Western Ontario, McGill University, Canada Foundation for Innovation, Agriculture and Agri-Food Canada, Environment Canada, and The Ontario Innovation Trust.
This was covered on CBC television's 'The National', on Oct. 8.
See the full announcement (PDF).
This fall we welcome Prof. Sarah Gallagher to our faculty.
Sarah is currently visiting from UCLA before she starts officially at UWO in July 2008.
Her astronomical interests lie deep in space.
Sarah investigates the nature of winds from luminous quasars (accreting supermassive black holes at the centers of distant galaxies) using space observatories covering the infrared to the X-ray. She also studies compact galaxy groups and starbursts.
Sarah is interested in the future of X-ray astronomy with the next generation of X-ray space observatories.
While she is settling in at Western, you can find out more details at her UCLA website.
We welcome two new faculty members to the department.
Dr. Pauline Barmby (left) and Dr. Lyudmila Goncharova (right) have just arrived to London and are settling in at Western.
Pauline Barmby comes to Western from Harvard University.
Pauline's research interests include observations of star clusters and distant galaxies in the infrared. In particular, Pauline has intensively studied our nearest large galaxy, the Andromeda galaxy, M31.
Lyudmila Goncharova's research interests include studying phenomena at the surfaces and interfaces, fabricating and characterizing systems with the controlled complexity under UHV conditions. The emphasis is on high-resolution ion beam analysis methods (complemented by other surface sensitive techniques) to study variety of systems from nanoelectronic and optoelectronic devices to materials for sustainable energy applications.
Lyudmila comes to Western after having been a Research Associate at The Department of Physics & Astronomy, Rutgers University, New Jersey.
This year's William H. Wehlau Prize winner is Frances MacKay (pictured at right). On the left is Prof. Emerita Amelia Wehlau (seated at left), who made the presentation.
Frances' Masters thesis is entitled "Modeling the Linear Continuum Polarization Produced by Massive Stars".
Frances is supervised by Prof. Carol Jones.
