General Assembly in Calgary
June 28 – July 1, 2018

The RASC General Assembly in 2018 Welcome!

On behalf of the GA Organizing Committee, as well as the entire Calgary Centre, I would like to welcome you to the 2018 General Assembly in Calgary, Alberta. We are honoured to host this year’s General Assembly over the Canada Day long weekend. 2018 is a landmark year, as it marks not only the 150th Anniversary of the RASC, but also the 60th Anniversary of the Calgary Centre. The GA Organizing Committee has assembled an exciting program of events, including top-notch speakers, a look back on the history of our Society, as well as field trips to give you a taste of the Calgary area, as well as some of the magnificent sights of southern Alberta and the Rocky Mountains.

Winds of Change Around Black Holes

Accretion disks, where matter with angular momentum spirals down through a disk, occur around objects ranging from the youngest stars to supermassive black holes. But not all of this material reaches the center of the disk. Instead some material is accelerated away from the disk. These outflows can be ejected in a narrow opening angle (what astronomers call “jets”) or can be relatively unfocused (what astronomers call “winds”).  While we do not know the precise processes that accelerate and collimate winds and jets, magnetic fields almost certainly play a key role. My team and I study black hole X-ray binaries, stellar-mass black holes accreting from a nearby star. We combine observations across the electromagnetic spectrum to learn about the physics of accretion and jets. In this talk, I will discuss how we have revealed two new windows onto the physics of inflows and outflows in X-ray binaries: fast variability measured across the electromagnetic spectrum (which provides the potential to accurately identify the accretion physics that launch relativistic jets) and the modelling of changes in the X-ray brightness of black hole X-ray binaries (which implies that strong winds from the accretion disk are universal). With the advent of new and upcoming facilities, we have a huge potential to take advantage of these winds of change in the next decade.

10 Things to do in the Summer of Planets

 

10 Things to do in the Summer of Planets

Members Only event.

Summer nights are the shortest, so why do I always do more observing in summer than any other season? Because there exists a surprising variety of fine celestial sights for the intrepid observer and/or photographer. In addition to these subtle annual delights, in the coming weeks and months our evening skies will be studded with bright apparitions of the planets Venus, Jupiter, Saturn and especially Mars.
