The Sunyaev-Zeldovich effect (SZE) provides a promising avenue to explore the properties of gas associated with halos and large-scale structures. However, due to contamination by the primary CMB, as well as foregrounds, projection effects, halo identification, and the beam size of current CMB surveys, it is not a trivial task to extract the signal precisely and accurately.

The recent discoveries of ferromagnetism in single atomic layers have opened a new avenue for two-dimensional (2D) materials research. Not only do they raise fundamental questions regarding the requirements for long-range magnetic order in low-dimensional systems, but they also provide a new platform for the development of spintronic devices. In this talk, I will present a series of studies on the family of layered ferromagnetic semiconductors, CrX3 (X = I, Br, Cl), in the atomically thin limit.

Climate and energy are prominent topics in the news and in our daily lives. We hear things like doubling the amount of CO2 in the atmosphere will raise the temperature of the Earth by 3 degrees. UBC's sustainability reports tell us that simply heating our classrooms, offices, and labs produces the equivalent of 42,000 tonnes of CO2 a year.

In electrostatics any excess charge on a conductor goes to the surface.  This is due, of course, to the mutual repulsion of like charges.  But it depends critically on the precise form of Coulomb's law and on the dimensionality of the conductor.  I will discuss some intriguing examples, including the vexed case of a conducting needle.

Related Upcoming Events:

A variety of new properties emerges in nanostructured metallic materials. These new properties are consequence of the collective excitation of conducting electrons, known as surface-plasmon resonances (SPR). For instance, the color of noble metals, such as gold and silver, can be controlled at the nanoscale by tuning the geometric characteristics of the nanostructures. Surface plasmon (SP) waves can propagate at the surface of thin metal films and this property can be explored for 2D imaging applications.

Related Upcoming Events:

The history of baryonic structures, particularly after the epoch of "Cosmic Dawn'"- the onset of the earliest stars and galaxies - is widely considered the 'final frontier' of observational cosmology today. Over the last decade, considerable effort has gone into investigating the nature of baryonic matter, theoretically and observationally. I will overview my current research related to atomic hydrogen and its evolution over 12 billion years of cosmic time, which involves a novel data driven framework developed for interpreting current and future observations.
