Dr. Tom Landecker, Researcher Emeritus, has recently been awarded the W.G. Schneider Medal–the highest expression of recognition for achievement at the National Research Council of Canada (NRC). This award recognizes an employee who has made an outstanding contribution to the NRC above and beyond the expectations of their job duties and who exemplifies the NRC’s values.

Dr. Landecker has been a major force in, and inspiration, to Canadian astronomy for 5 decades. With expertise in both engineering and astronomy, he has pushed technological improvement in the service of science, working with academic partners to develop novel telescopes at the NRC’s Dominion Radio Astrophysical Observatory (DRAO) which have enabled science, including some of the world’s foremost research on fast radio bursts (FRBs) here in Canada.

He is a publishing powerhouse, authoring 150 refereed journal articles in science and engineering. He celebrated his 80th birthday with 9 new papers in 2021 alone.

He is highly respected among his peers in astronomy, not just for his expertise, but also for his enthusiasm, leadership and mentorship, inspiring and encouraging the next generation of Canadian astronomers.

A legacy of telescopes and the discovery they enable

Dr. Landecker first arrived at the DRAO as a postdoctoral fellow, now a part of the NRC Herzberg Astronomy and Astrophysics Research Centre, in 1969.

In that role, he helped build the Synthesis Telescope–a unique imaging radio telescope that is open to all Canadian and international astronomers. Later, as Director of the DRAO, Dr. Landecker used the Synthesis Telescope to lead the team carrying out one of the largest surveys of the interstellar medium (dust and gas), the Canadian Galactic Plane Survey (CGPS, 1995-2014). He developed techniques for wide-field polarization imaging that have become standard in the field. The project produced over 400 refereed publications and continues to generate about 20 more each year. This success spawned an international era of wide-field radio surveys.

Following this, Dr. Landecker started the Global Magneto-Ionic Medium Survey (GMIMS), mapping out the polarization of the entire radio sky and making this available to all astronomers via the NRC’s Canadian Astronomy Data Centre. The GMIMS consortium comprises 14 Canadian and 22 international scientists, including many experts in magnetic field studies.

All of Dr. Landecker’s projects have developed new technical capabilities to support science that previously was simply not possible, from telescope upgrades and new algorithms for the CGPS, to new feed concepts and on-site demonstrations leading to the success of the Canadian Hydrogen Intensity Mapping Experiment (CHIME).

Supporting university collaboration

Dr. Landecker has also played an instrumental role in the Canadian Hydrogen Intensity Mapping Experiment (CHIME), sited at the DRAO. He advised university partners on the development of CHIME’s unprecedented “half-pipe” design, to realize a valuable new tool for cosmology and the hunt for FRBs. CHIME has been spectacularly successful, receiving the Governor General’s Award for Innovation (2020) and the Berkeley Prize of the American Astronomical Society (2022). A CHIME result on FRBs was lauded among the top scientific results of 2020 by both Nature and Science magazines.

“Tom has been absolutely crucial to the success of CHIME, on account of his deep knowledge of radio instrumentation, his amazing expertise on Galactic emission, his enthusiastic appreciation and detailed knowledge of a very broad range of research topics, and his very deep respect for his colleagues.”

Mark Halpern, University of British Columbia and Principal Investigator, CHIME

“Tom has been a major driving force behind Canadian radio astronomy for many decades… Tom has been absolutely essential to the development, construction, implementation, testing, calibration and scientific exploitation of CHIME.”

Victoria Kaspi, McGill University and Principal Investigator, CHIME/FRB

Mentorship

Dr. Tom Landecker’s enthusiasm, technical expertise, scientific focus and hands-on work ethic have directly inspired generations of students and postdoctoral fellows. He is an adjunct professor at the University of Calgary and the University of British Columbia, Okanagan. He has supervised 17 graduate students at Canadian universities, and worked closely with many more, acting in particular as a strong advocate and mentor for women in engineering and science.

“Tom Landecker has been my mentor since I was in graduate school… In a world filled with competitive agents, he is the most collaborative and inclusive person I know. My graduate students and I have benefited immensely from his knowledge and wisdom; I am eternally grateful for his support and friendship.”

Professor Jo-Anne Brown, University of Calgary

“Through mentorship, Tom has encouraged female students and postdocs, myself included, into the traditionally male-dominated fields of astronomy and engineering, always with a genuine trust in their abilities and their potential to contribute… His way of communicating empowers me to learn new concepts and fill in gaps in my understanding while feeling that I am part of a productive conversation.”

Anna Ordog, current Postdoctoral Fellow, University of British Columbia-Okanagan

Congratulations Tom!

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

 on

 

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.

This report by The Canadian Press was first published Sept. 9, 2024.
