Robert P. Lowe – In Memoriam

Professor Emeritus Bob Lowe passed away peacefully in his home in London, Ontario, at 11:00pm on Saturday, 7 January 2017. He had been battling cancer.

Robert P. (Bob) Lowe was born in England, and grew up in Port Stanley. As an Honors Mathematics and Physics undergraduate at Western, he may well have been a regular commuter on the London Port Stanley train. He graduated from Western in 1957 and began working for the Defence Research Board (DRB) in Valcartier, Quebec. During his tenure at DRB, Bob continued his studies in atmospheric physics at Western under the supervision of Ralph Nichols, eventually graduating with a PhD in Physics in 1967. Bob began as a faculty member in Western’s Department of Physics in 1968, retiring from the recently formed Department of Physics and Astronomy in 2001.

Bob focused his research on the infrared airglow produced by the Hydroxyl radical. He became a world-renowned expert in satellite based observations of airglow. At one stage he used airborne-ready equipment borrowed from the DRB at Elginfield Observatory, collaborating with Jim Moorhead  and William Wehlau on various astronomy projects, observing the infrared spectra of a comet, as well as the Orion Nebula and stars in its environs. Bob also used the Canada France Hawaii Telescope (CFHT) to observe HeH+ in planetary nebula NGC 7027.

Bob Lowe did not let retirement hamper his research efforts, just recently publishing a paper with co-author and his former PhD student, Dave Turnbull. Bob’s research legacy can be partially viewed on his ResearchGate web site.

Bob had a brilliant mind, and a big heart, combined with sophisticated sense of humour.  His world-wide travels as a scientist allowed him to indulge in his love of international cuisine.

January 2017 Retreat

John and Jan prepare for Michel’s yoga class.

Department of Physics and Astronomy faculty and staff attended a special post-Christmas retreat at Ivey Spencer Leadership Centre on January 4, 2017.

The day began with a wonderfully relaxing hour-long yoga class from teacher Michel.  Everyone thoroughly enjoyed it.

With stress levels dissipated, the  freshly energized retreat goers went on to a another activity, the head chef’s challenge. Placed in front of each of 4 groups of challengers was a table of sweets, candies, various fruits, graham crackers, skewers, some royal icing, and some thinner consistency icing, along with parchment pastry / piping cone paper. The idea was to have each of the teams not only assemble a creation on a 30cm. by 50cm. plate, but to concoct a story line around the creation. They were given 45 minutes to complete their chefs d’oeuvre.

Group 1 came up with a graham cracker Keck telescope and a spiral galaxy containing an assortment of sweet galactic residents. Pauline Barmby was the group presenter, and did a fine sales job.

Group 2, the overall chef’s pick for winner, had a theme of ‘Solar Eclipse Aug. 21, 2017 at Cronyn Observatory’. This display had everything, including a pineapple Sun,  chocolate Moon,  melon and cracker observatory, Alumni traffic circle, telescope, and a basement filled with historic artifacts.  Jan Cami was sales person for this project, and it is rumoured that he payed off the chef.

Group 3’s presentation was titled “Worlds Collide” and was a well presented mishmash of Sci-Fi lore, including Dr. Who’s Tardis phone booth, a Borg Cube, as well as a small collection of Sci. Fi. characters. Brian Davis did the sales work on this one.

Group 4’s sales pitch was done as a group effort, with a Star Trek theme. The story line has the crew of the U.S.S. Enterprise visiting a planet that is filled with tasty alien life forms.

Lunch followed in DK’s Lounge.

After lunch the group was treated to a very interesting talk by Western Political Science professor Rado Dimitrov. Professor Dimitrov has been the Bulgarian representative to the E.U. during the recent international climate talks, culminating in the Paris Agreement. The audience was given a wonderful taste of the Paris meetings, as well as some insights into the science and diplomacy centred on the global warming issue. There were lots of questions from the audience.

The final item on the agenda was a brainstorming session on several important departmental topics, projects, and initiatives. This was led by Chair Bob Sica.

Star formation model predictions possibly borne out by recent observations

Professor Shantanu Basu and longtime colleague Eduard Vorobyov of the University of Vienna had in 2006 developed a gravitational instability and fragmentation model which predicts stellar accretion outbursts on time scales of hundreds of years or less.  Other models of the early life of stars predict events occurring at much larger time scales, on the order of thousands of years.

A recently observed short term ( ~ 40 years) accretion burst of the young star V346 Normae will certainly have astronomy community revisiting the Basu-Vorobyov model.   This is very exciting news indeed.

The Faculty of Science awards and recognition luncheon was held on Tuesday, 13 December 2016 in the Great Hall at Summerville House.

Jan Cami was formally presented with his Undergraduate Teaching Award.

Tamie Poepping received the special Physics and Astronomy Achievement Award, which was presented by Chair Bob Sica.

Bob and his fellow Science Chairs all received service awards from Dean of Science Charmaine Dean.

New hires were recognized, including Professor Rob Cockcroft, and staff members Emily Adams, Paul Christiaans, and Abedin Abedin.

 

Christmas town hall meeting and luncheon 2016

A town hall meeting and Christmas luncheon were held on Friday, December 9, 2016.

Department Chair Bob Sica welcomed the gathering. Many retired faculty and staff attended, including Mila Kagan, Willy Lennard, Ian Mitchell, Harry Chen, David Rosner, John Landstreet, James Moorhead, Michel Debruyne, and Patrick Whippey. Postdoctoral fellow Elizabeth Silber dropped in from Rhode Island. Custodial staff members Emira Abdovic and Mike MacDonald were also present.

Bob’s first order of business was to have the staff introduce themselves. This was followed by a formal welcome of new staff members Emily Adams, Abedin Abedin, and Paul Christiaans, along with new faculty member Rob Cockcroft.  It was then time to honour three new retirees, these being staff members Clara Buma, and Peter Frank, as well as faculty member Dick Holt. This was an emotional moment. Bob spoke about Clara’s career in which she was the face of the main office for years.  John deBruyn thanked Peter for his service of over 40 years, while Professor Emeritus David Rosner spoke of Dick Holt’s career, beginning with his famous thesis on the topic of Bell’s Theorem. Professor Emeritus Patrick Whippey spoke warmly of his time with Peter, Clara, and Dick.

Chair Bob then turned the discussion to new departmental academic and outreach initiatives. Faculty committee members Martin Houde, Els Peeters, Tamie Poepping, and Jan Cami spoke to the various topics.

A moment was taken for John de Bruyn to formally honour Jackson Scholarship winner Cameron Hopkins, and William Wehlau Prize winner Isabelle Cyr.

A question and answer session followed, along with a tribute by Professor Emeritus John Landstreet to recently deceased Professor Emeritus Romas Mitalas.

Hungry stomachs then had to patiently wait through two group photos sessions, after which the everyone headed to the buffet tables. It was interesting that some headed directly to the dessert table!

Lunch was followed by informal building of gingerbread houses and Christmas ornaments.  Individual photos were taken by the Christmas trees.

There were some wonderful Christmas sweaters in evidence, and certainly those worn by Emily Pass and Peter Brown caught the attention of the Chair.

Romas Mitalas – In Memoriam

romas_mitalas_1933_2016

Professor Emeritus Romas Mitalas passed away quietly late on Wednesday, 30 Nov.  2016, at 83 years of age.

Romas was born in Kaunas, Lithuania in 1933. The second world war uprooted many Baltic families, and thus he came to Canada.

He received his B.A. and M.A. in Applied Mathematics from the University of Toronto. He then went on to Cornell University where he received a PhD. in Theoretical Physics.

Romas was first hired by the Department of Physics at Western in 1964.  He then moved over to the newly formed Department of Astronomy in 1968. He retired in 1996. After retirement Romas enjoyed coming to colloquia and other events.

Romas was an expert in stellar interiors, as trembling graduate students could attest.

He is survived by his wife Nancy, sister Giedre, sister-in-law Dalia, along with many nieces and nephews.

Romas was a true intellectual, being extremely curious about the world and its people. He was extremely kind-hearted, and generous, also seeing the humour in many things. A typical conversation with Romas could be politically charged, but could also touch on the beauty of there being roughly Pi x 10**7 seconds in a year, or could move to the quality of maple syrup in Ontario.

He will be dearly missed.

International pot luck lunch a savoury affair

pot_luck_28nov
Staff members with their contributions.

The graduate student council organized one of their traditional pot luck lunches for Monday, Nov. 28, 2016.

The pot luck was held in the beautiful confines atrium of the Physics and Astronomy building atrium.

There was a wonderful turnout of graduate students, faculty, and staff, who brought an incredible variety of dishes from all over the world.

The challenge was to try to sample a bit of everything.

A nice variety of dessert dishes awaited lunch goers.

Many thanks to grad council members Nirosh Getangama and Sayantan Auddy for making this a success.
