Victoria Michelle Kaspi CC FRS FRSC (born June 30, 1967) is an American-Canadian astrophysicist and a professor at McGill University. Her research primarily concerns neutron stars and pulsars. [1]

Early life and education

Kaspi was born in Austin, Texas, but her family moved to Canada when she was seven years old. [1] She completed her undergraduate studies at McGill in 1989, and went to Princeton University for her graduate studies, completing her PhD in 1993 supervised by Nobel Prize-winning astrophysicist Joseph Taylor [1] [2]

Career and research

After positions at the California Institute of Technology, the Jet Propulsion Laboratory, and the Massachusetts Institute of Technology, she took a faculty position at McGill in 1999. [1] At McGill, she held one of McGill's first Canada Research Chairs, [3] and in 2006 she was named the Lorne Trottier Professor of Astrophysics. [4] She is also a Fellow in the Canadian Institute for Advanced Research. [5]

Kaspi's observations of the pulsar associated with supernova remnant G11.2−0.3 in the constellation Sagittarius, using the Chandra X-ray Observatory, showed that the pulsar was at the precise center of the supernova, which had been observed in 386 CE by the Chinese. This pulsar was only the second known pulsar to be associated with a supernova remnant, the first being the one in the Crab Nebula, and her studies greatly strengthened the conjectured relationship between pulsars and supernovae. Additionally, this observation cast into doubt previous methods of dating pulsars by their spin rate; these methods gave the pulsar an age that was 12 times too high to match the supernova. [6]

Kaspi's research with the Rossi X-ray Timing Explorer showed that soft gamma repeaters, astronomical sources of irregular gamma ray bursts, and anomalous X-ray pulsars, slowly rotating pulsars with high magnetic fields, could both be explained as magnetars. [5] [7]

She also helped discover the pulsar with the fastest known rotation rate, PSR J1748-2446ad, [2] star clusters with a high concentration of pulsars, [2] and (using the Green Bank Telescope) the "cosmic recycling" of a slow-spinning pulsar into a much faster millisecond pulsar. [8] [9]

Awards and honours

Personal life

Kaspi is Jewish. [27] Her husband, David Langleben, is a cardiologist at McGill [3] and the chief of cardiology at Sir Mortimer B. Davis Jewish General Hospital in Montreal. [4]

Magnetar type of neutron star

A magnetar is a type of neutron star believed to have an extremely powerful magnetic field (∼1013 to 1015 G, ∼109 to 1011 T). The magnetic field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays. The theory regarding these objects was proposed by Robert Duncan and Christopher Thompson in 1992, but the first recorded burst of gamma rays thought to have been from a magnetar had been detected on March 5, 1979. During the following decade, the magnetar hypothesis became widely accepted as a likely explanation for soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs).

Brenda Milner Canada-based British neuroscientist and neuropsychologist

Brenda Milner, is a British-Canadian neuropsychologist who has contributed extensively to the research literature on various topics in the field of clinical neuropsychology, sometimes referred to as "the founder of neuropsychology". As of 2010, Milner is a professor in the Department of Neurology and Neurosurgery at McGill University and a professor of Psychology at the Montreal Neurological Institute. As of 2005, she holds more than 20 degrees and continues to work in her nineties. Her current work explores the interaction between the brain's left and right hemispheres. Milner has been called the founder of neuropsychology, and has proven to be an essential key in its development. She received the Balzan Prize for Cognitive Neuroscience, in 2009, and the Kavli Prize in Neuroscience, together with John O'Keefe, and Marcus E. Raichle, in 2014. She turned 100 in July 2018 and at the time was still overseeing the work of researchers.

John Polanyi Hungarian-Canadian chemist

John Charles Polanyi, is a Hungarian-Canadian chemist who won the 1986 Nobel Prize in Chemistry, for his research in chemical kinetics. Polanyi was born in Berlin, Germany prior to his family emigrating in 1933 to the United Kingdom where he was subsequently educated at the University of Manchester, and did postdoctoral research at the National Research Council in Canada and Princeton University in New Jersey. Polanyi's first academic appointment was at the University of Toronto, and he remains there as of 2019. In addition to the Nobel Prize, Polanyi has received numerous other awards, including 33 honorary degrees, the Wolf Prize in Chemistry and the Gerhard Herzberg Canada Gold Medal for Science and Engineering. Outside his scientific pursuits, Polanyi is active in public policy discussion, especially concerning science and nuclear weapons. His father, Mihály (Michael), was a noted chemist and philosopher. His uncle Karl was an economist. According to György Marx he was one of The Martians.
