Abstract: ALMA, the Atacama Large Millimetre/submillimetre Array, has begun science operations after more than a decade of development and construction. Although the observatory has not yet reached its full capability, it is already making important new discoveries. In the area of low mass star formation, ALMA offers very high angular resolution and high sensitivity observations of nearby molecular clouds, the most well-studied of which are in the northern hemisphere. However, it is for studies of the less well-known clouds of the southern sky that ALMA will excel.

One of these molecular cloud complexes lies in the Lupus constellation, and an international consortium of ALMA scientists have begun an effort, the SOLA program, to probe the star formation activity in this region. It turns out that the clouds in Lupus and its star formation has some unique characteristics that make of of great interest for studies of star formation in different environments, particularly for the formation of very low mass stars and brown dwarfs.

Bio: Lewis Knee is a radio astronomer at NRC Herzberg in Victoria. He received his PhD in Radio and Space Science at the Chalmers University of Technology in Sweden in 1991. Since then he has worked in radio astronomy observatories in Europe, Canada, and Chile, most recently six years at ALMA in the Atacama Desert. His main scientific interests are in spectroscopy, star formation, molecular clouds, and the interstellar medium of our Galaxy.

Monthly meeting speaker: Frontiers in Adaptive Optics and Stellar Spectroscopy: Searching for the First Stars Ever Formed – Dr. Masen Lamb

Frontiers in Adaptive Optics and Stellar Spectroscopy: Searching for the First Stars Ever Formed – Masen Lamb, PhD student at the University of Victoria working in Astronomy and Telescope instrumentation

To compete with space telescopes such as Hubble, current (and future) optical ground based telescopes employ a technology called Adaptive Optics. This technology uses mirrors to cancel out the affects of the atmosphere and provide near diffraction-limited images. One application of Adaptive Optics in astronomy is to resolve dense regions of stars in the centre of our Galaxy. When this application is combined with infrared spectroscopy we can start to hunt for the oldest stars in our Galaxy. I will talk about the latest technologies in both Adaptive Optics and stellar spectroscopy and discuss some of their astronomical implications.

Monthly meeting speaker: Galaxy mergers in the nearby Universe – Dr. Sara Ellison, Professor, UVic Physics & Astronomy

Posted by as Meetings

This large “flying V” is actually two distinct objects — a pair of interacting galaxies known as IC 2184. Both the galaxies are seen almost edge-on in the large, faint northern constellation of Camelopardalis (The Giraffe), and can be seen as bright streaks of light surrounded by the ghostly shapes of their tidal tails.

Despite the emptiness of space, mergers between galaxies are surprisingly common. Around 1% of galaxies in the nearby Universe are currently experiencing an interaction of some kind. I will describe research that uses both observations and computer simulations to trace the dramatic effect of these interactions on a galaxy’s history: how the interaction can lead to massive bursts of star formation, alter the interstellar chemistry and even provide fuel for the central supermassive black hole.

Jan 14, 2015 Speakers: John McDonald & Reg Dunkley – Rare Meteor Manifestations

RASC Victoria Monthly Meeting – Jan 14, 2015, 7:30PM at University of Victoria, Bob Wright Building A104

 

Speakers: John McDonald & Reg Dunkley – Rare Meteor Manifestations

 

While photographing the Geminid meteor shower this year, John McDonald managed to capture part of a very bright meteor track and smoke plume near the Orion Constellation. Subsequently, John and Reg Dunkley have analyzed the data and speculated on this rare phenomena.

’Astronomers’ Work is of Great Value’: The Construction of the Dominion Astrophysical Observatory and the Foundations of the Modern Canadian Astronomy Program, 1905-1930 by Dan Posey

 

daoThe Canadian astronomical program rapidly expanded under the guidance of William King and John Stanley Plaskett at the turn of the twentieth century. The Dominion Astrophysical Observatory, constructed between 1914 and 1918 was considered an engineering marvel in its time, that radically departed from traditional designs, and was briefly the world’s largest operating telescope upon its completion. This presentation will examine how the construction of the observatory represented a shift in the commitment to scientific programs by the Canadian federal government, and the observatory’s place within a growing national identity during the First World War. Further, it will assess the cultural implications of the project for British Columbians and the establishment of an astronomical tradition for the province.

Dan Posey is a second-year graduate student in the University of Victoria’s History program. He completed his undergraduate degree from the same institution in 2012. His thesis focuses on the history of the Dominion Astrophysical Observatory and its contributions to both Canadian Astronomy and British Columbia throughout the twentieth century.

Better Observer?

“How can you become a better observer? How can you do something other than look at the same fifteen objects every time you go out? Can you learn to star hop to IC 289? What equipment works best for visual observing? What charts are best for visual observing? Do you need finder charts? Should you keep a logbook? Learn the answer to these and other burning questions next Wednesday night.”

A great topic, especially for those newcomers to astronomy who have joined us recently!

As usual, we’ll meet afterwards in the astronomy lounge on the fourth floor of the Elliot building for chat and coffee.

Jan 8, 2014 – “A brief update on modern physics” – W. John McDonald

From the smallest constituents of atoms to the largest structures in the Universe nothing is as it seemed in 1900 just before relativity and the quantum revolutionized science. My aim is to give a broad-brush picture of the material world that emerges from observations of systems ranging in size from quarks, leptons and the Higgs boson to stars, galaxies and universe itself. It is a picture that differs greatly from our common sense ideas. Those ideas evolved historically based on interpreting information we got from our human senses. With the development of modern instruments that let us see further and deeper into nature’s secrets a picture of a very different reality is evolving. It is an incomplete picture but rich and compelling nevertheless.
