Project title: Cancer nanotechnology: Use of gold nanoparticles for improved cancer therapeutics
Gold nanoparticles are being used as radiation dose enhancers in cancer therapy. I will be using gold nanoparticles encapsulated in liposomes as my therapeutic system for this study.  Breast cancer cells (MDA-MB-231) will be first incubated with the nanoparticle system. Once nanoparticles are internalized within cells, a radiation dose of 2 Gy will be given. Effectiveness of the treatment will be assessed using clonogenic assay. As an NSERC USRA student, I am studying the cellular uptake of this nanoparticle system. If I am given this award, I have the opportunity to test this nanoparticle system in radiation therapy.

Project title: The puzzle of one-armed tails in Galactic satellites
The Magellanic Stream is a trail of gas that emanates from the Magellanic Clouds and traces their orbit around the Milky Way. It is heavily lopsided, lagging behind the Clouds in their orbital path. This one-armed feature, together with the lack of stars associated with the  Stream, have raised question about its origin. If caused by Galactic tides, then one would expect a two-armed tail structure and the presence of stars. If caused by ram-pressure onto a tenuous halo of hot gas then its spatial distribution would not trace accurately the orbital path of the Clouds. We intend to address this puzzle using cosmological simulations of the formation of the Local Group of Galaxies from the APOSTLE project. Preliminary work has shown the presence of a number of one-armed features emanating from satellite galaxies in APOSTLE runs. Their detailed analysis should yield invaluable clues to interpret the properties of the Stream and to elucidate its origin.

Project title: ALTAIR Dark Energy Analysis and Instrumentation Development
We request a student to join the international ALTAIR team (http://projectaltair.org) to contribute to the development of the propulsion system for future ALTAIR payloads. Propulsion will greatly benefit the future of ALTAIR flights as the ability to more precisely control the flight path would allow ALTAIR to pass directly in front of type 1A supernovae rather than merely nearby. This allows for better calibration for the magnitude of the supernovae or other astronomical light sources. ALTAIR is a collaboration of 4 Canadian universities and 2 US universities plus NRC and NIST. Analysis of the observation and telemetry data, in order to obtain precise photometry of supernovae or other astronomical light sources, brings students into the heart of the scientific analysis required to obtain results.

The anisotropy of light sources is often cited as a source of difficulty and systematic uncertainty in experiments. The proposed project seeks to create a light source that will offer improved isotropy over current methods. Applications are widespread and some examples include light dosimetry of human and animal tissue, imaging of water properties in the aphotic zone of the ocean, facial recognition, and in photometric calibration of telescope and camera optics. The primary focus will be toward improving the photometric calibration of Type Ia supernovae for Dark Energy Measurement.
A spherical homogeneous 60-sided polygon has been constructed with a light emitting diode (LED) affixed to each surface. The polygon is then placed at the centre of a diffusing sphere. The LEDs are controlled individually by an array of micro-controllers programmed to ensure that a uniform light intensity is emitted. Now that construction is complete a photodiode mounted on a goniometric test stand along with a dark room are being constructed to measure the irradiance as a function of angle which will determine the isotropy of the device.

One of the characteristic features of turbulent flow is the phenomenon of energy cascade. In three-dimensional classical fluids, a direct cascade implies the break-down of large-scale vortices until energy is dissipated by viscosity at small scales. Incompressible, inviscid two-dimensional classical fluids, however, exhibit different characteristics due to an additional invariant. Instead of being dissipated at small scale, vorticity aggregates into long-lived, large-scale structures. Their emergence is associated with a phase transition at negative-absolute temperature states. This phenomenon is known as an inverse energy cascade.  It may be understood by studying the idealized point-vortex model.
Superfluids, such as Bose-Einstein condensates, may also be agitated into states of chaotic vortex motion. Two of the main differences with classical turbulence are that quantum vortices have a well-defined length-scale and can only be removed from the fluid through annihilation. For that reason, the point-vortex model is relevant for 2D superfluids. Experimental and numerical evidence of the presence of a Kolmogorov spectrum in 3D quantum turbulence have motivated more work to link classical and quantum turbulence and understand the characteristics of 2D quantum turbulence.
The main goal of this research is to get a better understanding at the role of vortex annihilation in Bose-Einstein condensates. We wish to see the effect of vortex annihilation on the phase transition at negative temperatures in the point-vortex model. We will compare the kinetic energy spectra and derive the spatial velocity correlation functions for three models: the point-vortex model, the point-vortex model with annihilation, and the Gross-Pitaevskii equation.

At present, the most important problem in the area of physical cosmology is to understand how galaxies arise and how they acquire their observed properties - in other words, identify the physical processes that shape galactic evolution and understand their action. This is key to not only making sense of the various multi-wavelength observations of galaxy populations at different epochs over the past 10 billion years, but also understand how structures at one epoch relate to structures at another, and how different components of the universe - dark matter, gas and stars - interact. Prof. Babul's research group has been using state-of-the-art, numerical simulations of the formation and evolution of cosmic structure to address the above issues. The proposed project has two objectives: first, to test some of the recent technical improvements that have been proposed in the community for a better description of the fluids dynamics by the simulation code, and second, to test the different facets of the physical model on which the simulations are based. Specifically, the project will involve running a suite of high-resolution cosmological simulations, making use of Dr. Babul computing time allocated on the High Performance Computing WestGrid network, as well as analyzing the output of these numerical simulations. This dataset, covering a wide range of both technical and physical parameters, will enable to assess the properties of the structures within the resulting virtual universe, and compare these to published results from observational surveys. The results will be written up and submitted for publication.

The universal star formation rate density (SFRD) relation describes the rate at which new stars form in the universe considered over its 13.7 billion year lifetime.  Astronomers have recognized for some time that the rate at which stars form in the universe increase slowly as the universe aged, reaching a broad crescendo some 10 billion years ago.  The universal star formation rate in the present day universe is some 10 times smaller than at the peak. 
The project will use sensitive narrow band images taken with the Canada France Hawaii Telescope (CFHT) to identify a sample of some 600 [OII] line emitting galaxies at a redshift z=1.8 (corresponding to the peak in the universal SFRD relation).  The project will be developed in two phases: 1) the multi-wavelength brightness of each emission line galaxy will be analyzed employing a photometric redshift analysis to sift the z=1.8 [OII] galaxies from interloping emission line galaxies along the line of sight, 2) having identified the z=1.8 [OII] emitting galaxies, the sample will be processed to learn about the population as a while via statistics such as the luminosity function, the emission line equivalent width distribution and the colour distribution of galaxies.  This project – which will generate one of the largest samples of z=1.8 [OII] emitting galaxies – will begin to reveal in what type of galaxies star formation occurs and under what physical conditions.  In a sense it will provide us with a ringside seat at the peak period of universal star formation.

This project will test the Hanbury Brown and Twiss effect using photons in a bench top experiment. This is a quantum phenomenon where photons (particles of light) tend to 'bunch' together. The effect has been used to measure the size of stars and the size of particle interactions at high energy colliders. To accomplish this, construction of a device sensitive enough to detect single photons must be built, capable of detecting millions of them per second. This can be done using a recently invented device called an avalanche photodiode.  The physics department is interested in developing expertise in this area because being able to detect single photons opens up the possibility to do a large number of quantum optics experiments, including spooky entanglement measurements.

Damped Lyman alpha (DLA) galaxies can be used to probe the evolution of galaxy populations. Using high resolution spectra obtained for ~10 of these objects, chemical abundance measurements will be gathered. Of the chemical species of interest, several of them are rarely detected elements outside of the Local Group (such as B, Ga, Ge, Sn and Pb). These observations should provide insight into understanding nucleosynthetic processes in the galactic environment by obtaining star formation rates, and the relative number of low, intermediate and high mass stars within the galaxies of interest.  This project would involve using previously developed software to identify and measure the column density of a specified list of carefully chosen absorption lines. This will be repeated for all the objects of interest. Some of these objects may require extra data reduction prior to determining the chemical abundances. Once completed, an analysis of the results will be carried out to study the stellar population within these DLA systems.

This project will conduct an analysis of the chemistry and atmospheres of the outer halo globular cluster Palomar 15.  Palomar 15 is described as an enigmatic globular cluster, amongst the most distant and least studied GC’s in our galaxy.  Determining a detailed chemistry for the cluster, namely [α/Fe] and [Fe/H] ratios, is integral to increasing our understanding of the evolution of the Milky Way’s outer halo.1  For example, should the Palomar 15 cluster have an observed [α/Fe] ratio lower than comparable inner GC’s, it is likely that the exterior region of the galaxy originated externally from dissolved dwarf galaxies.2   Photometric data was obtained from the Ultraviolet and Visual Echelle Spectograph at the VLT and from the Hubble Space Telescope after observation of four target red giant stars with known radial velocities, by Dr. Venn and colleagues.1  This data was reduced to one dimensional flux versus wavelength spectra by Anna Delahaye, a former Astr 429B student, and will be the primary source of data.  Through derivation of α-element (ie. elements formed by alpha particle fusion – Mg, Si, Ca, Ti), H and Fe abundances, as well as the ratios previously outlined, an in-depth comparison can be conducted relative to similar, well studied inner galaxy objects.  Further, atmospheric modelling may be performed on the target stars to provide additional information concerning the evolution and age of the cluster, which carries important and direct implications for the origin and age of the outer halo of our galaxy.
