GPU Correlators for the CHIME Computational Radio Telescope

[bra_border_divider top=\’5\’ bottom=\’15\’] [one_half] Dr. Peter Klages, Dunlap Institute The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is located in a radio-quiet valley near Penticton, BC, and aims to study Baryonic Acoustic Oscillations for red-shifted hydrogen between z = 0.8 to z = 2.5.  The CHIME telescope is a computational radio telescope composed of multiple parabolic

Making a Wide Integral Field Infrared Spectrograph

[bra_border_divider top=\’5\’ bottom=\’15\’] [one_half] Dr. Suresh Sivanandam, Dunlap Institute Infrared integral field spectrographs have become a very important tool in understanding the nature of high redshift Universe. But due to their small field-of-view, they are very limited when it comes to observing nearby more extended objects. The near-infrared band has many interesting spectral features that

AID Show & Tell

[bra_border_divider top=\’5\’ bottom=\’15\’] [one_half] The goal of this activity will be to find out what instrumentation work is going on right now and to discuss some of the associated accomplishments and challenges. The meeting will have a loosely structured format where everyone will be encouraged to bring a either picture, plot, and/or a piece of

Searching for Planets with SDSS/MARVELS

[bra_border_divider top=\’5\’ bottom=\’15\’] [one_half] Dr. Duy Cuong Nguyen, Dunlap Institute The primary mission of SDSS/MARVELS was to search for exoplanets using an augmented radial velocity technique. While there are numerous ongoing radial velocity surveys, SDSS/MARVELS employs Dispersed Fixed-Delay Interferometry (DFDI), and combines interferometry with multi-object spectroscopy to allow precision monitoring of dozens of targets simultaneously.

Future Plans for the Balloon-borne Imaging Testbed

[bra_border_divider top=\’5\’ bottom=\’15\’] [one_half] Prof. Barth Netterfield The BIT project is the first step in an effort to open up the application of balloon-borne telescopes to wide field, high resolution imaging in the UV/optical bands. Questions to consider for the AID discussion: 1) What would you do with such an instrument? 2) What bands should

Geometric Phase Holograms and Multi-Twist Retarders

[bra_border_divider top=\’5\’ bottom=\’15\’] [one_half] Geometric Phase Holograms and Multi-Twist Retarders: Surprising control of phase and polarization via patterned birefringence Dr. Michael Escuti, North Carolina State University It is well known that anisotropic materials can be used to transform polarization, but it is something of an underground insight that they can also be used to control

Phosphorus in the Young Supernova Remnant Cassiopeia A

An international team of astronomers, including Prof. Dae-Sik Moon at the University of Toronto, has measured for the first time the abundance of phosphorus created in a supernova explosion. “These five elements are essential to life and can only be created in massive stars,” says Moon. “They are scattered throughout our galaxy when the star explodes, and they become part of other stars, planets and ultimately, humans. This is why Carl Sagan said we are made of ‘starstuff’.\”
