Fri June 20 – 8 pm CHIME: Mapping the Universe with Canada’s newest Radio Telescope

CHIME: Mapping the Universe with Canada’s newest Radio Telescope

Speaker: Professor Keith Vanderlinde, Dunlap Institute for Astronomy and Astrophysics, University of Toronto

Cos                                                                              Professor Keith Vanderlindemologists from across Canada have recently undertaken the construction of a huge new radio telescope, a 100m x 100m array of dishes, designed to unravel some of the deepest mysteries in modern cosmology. The Canadian Hydrogen Intensity Mapping Experiment (CHIME, for short) is being built at the Dominion Radio Astrophysical Observatory (DRAO), located in BC’s Okanagan Valley, and will soon become a powerful new lens on the cosmos. Over its 5-year survey, CHIME will map out a larger volume of the Universe than ever previously studied, with the ultimate goal of tracing the expansion history and studying the characteristics of Dark Energy, a mysterious negative-pressure substance which dominates the energy density of the modern Unvierse.

CHIME

CHIME

CHIME is an ambitious new type of telescope, a hybrid digital interferometer, composed of five 20m x 100m parabolic reflectors which focus radio waves in one direction (east-west) while digital interferometry is used to resolve beams in the other (north-south). Earth rotation sweeps its view across the sky, yielding complete daily coverage of the northern celestial hemisphere. The full sized 100m x 100m instrument is funded, under active development, and expected to turn on in early 2016 — I’ll be taking you through the motivation, design, and progress on CHIME, including the 40 x 37m “Pathfinder” version of the telescope, already built and operating at the DRAO.

Keith Vanderlinde studies the nature and evolution of large-scale structure in the Universe, as well as the evolution of the cosmos itself. Studying large-scale structure requires specialized instruments and Vanderlinde is a member of collaborations using and developing ones that are unique.

One such instrument is the South Pole Telescope (SPT). The SPT surveys the sky at microwave frequencies to reveal the Cosmic Microwave Background—a snapshot of the Universe less than 400,000 years after the Big Bang.

Vanderlinde is also a member of a cross-Canada collaboration building an innovative, digital radio telescope near Penticton, B.C. TheCanadian Hydrogen Intensity Mapping Experiment, or CHIME, is a radio array that will create a three-dimensional map of the largest volume of the Universe ever.

The group includes the Dunlap Institute, CITA, UBC, McGill University and the Dominion Radio Astrophysical Observatory. In January, the Canadian Foundation for Innovation approved funding to build the CHIME telescope.

Vanderlinde is also a member of a team using the Algonquin Radio Observatory in northern Ontario and the Giant Metre-wave Radio Telescope in India to make ultra-high resolution observations of pulsars, using pockets in interstellar gas as billion-kilometre-wide lenses.

PROFESSOR KEITH VANDERLINDE

Vanderlinde received his PhD from the University of Chicago and joined the Dunlap Institute in 2013.

Tues June 3 9pm – Riverwood Observing Night

Observe the Moon and planets through large telescopes

Come out and observe the universe at the Riverwood Conservancy! Join members of the Mississauga Centre of the Royal Astronomical Society of Canada as they set up large telescopes to look at the Moon, planets and stars. Observing will take place on the green in front of Chappelle House. The event starts at dusk is free and open to everyone.

Large telescopes will be set up and pointed at the Moon, the planets Jupiter, Saturn and Mars and other objects beyond our solar system.

Look for meteors, artificial satellites and anything else in the skies over Mississauga.

Note: If the weather is cloudy, the observing will be delayed one day. Check this web site for GO/NO GO information on the afternoon of the 06th.

The weather looks good for tomorrow night. It might be a little cool so dress warmly. We should have great views of the Moon and three planets – Jupiter, Mars and my favourite – Saturn!

Fri May 23 – 8 pm Gas Falling Into Black Holes: A Surprising Discovery

dec10PatHallPhoto[1]Gas Falling Into Black Holes: A Surprising Discovery

Pat Hall from York University will be our speaker.

A black holes is inferred to exist at the center of every massive galaxy, including our own Milky Way. We cannot see such a black hole directly, but we can see light from hot gas orbiting the black hole.

This gas forms a disk larger than the Earth’s orbit around the Sun and hotter than the surface of the Sun, putting out enough light to be seen across the universe; we call this light a quasar.

For 45 years we have known that some quasars have part of their light absorbed by gas streaming AWAY from the black holes, in winds lifted from the surface of these disks. A few years ago, I discovered some cases of absorption which may come from gas streaming INTO the black holes.  But it may be difficult to explain the speeds at which the gas appears to be falling into the black holes in these quasars; they may instead be cases of winds in systems with two black holes orbiting each other!

RASC GENERAL ASSEMBLY

2014_GA_Logo[1]

June 26th – June 29th 2014

Join the members of Victoria Centre as we commemorate 100 years of being a RASC Centre at our 2014 RASC General Assembly. To add to the festivities, we will also be celebrating the 100th anniversary of the Dominion Astrophysical Observatory, located in Saanich B.C., just to the north of downtown Victoria.

The 2014 General Assembly will showcase the DAO, the University of Victoria’s new observatory located on the campus of our assembly’s headquarters and a wide-ranging scientific and cultural schedule of events for your family, all conducted against the spectacular natural beauty of Canada’s West Coast. Guest Speakers include Dr Laura Ferrarese,  Bob McDonald of CBC’s Quirks and Quarks, and RASC’s own Peter Broughton.

Victoria is serviced by both of our domestic air carriers and can be reached by convenient car ferry service connecting Victoria to Vancouver and Seattle, Washington.

From on-campus accommodation at the University of Victoria to nearby hotel and RV facilities, there are many lodging options available in the Greater Victoria for RASC members.

Registration https://www.rasc.ca/events/home

Please join us in Victoria June 26 – June 29, 2014!

Fri Apr 25 – 8 pm Ultra-low Surface Brightness Imaging with Project Dragonfly

Roberto_abraham[1]Ultra-low Surface Brightness Imaging with Project Dragonfly

Dr. Roberto Abraham will describe early results from Project Dragonfly, a Toronto/Yale instrument concept whose goal is to open up the new observational regime of ultra low surface brightness astronomy at visible wavelengths. Its design is optimized for testing the most fundamental prediction of galaxy formation models, namely that at low surface brightness levels all galaxies are embedded within a sea of complex substructure.
The project couples innovative observing techniques (multiple redundant unobstructed beam paths and real-time modeling of sky variations for precision control of systematics) with new technologies, such as sub-wavelength nano-fabricated optical coatings to minimize scattered light and ghosting.

Dr. Abraham is a Professor in the Department of Astronomy & Astrophysics at the University of Toronto. He is also the Associate Chair for Graduate Studies in the department.
