Undergraduate Seismology Internship (pdf) As a Math major I loved the beauty of high level Mathematics but struggled to see the application. In Physics I found a relevant and tangible application to the beauty of Mathematics. However, I wanted to apply my new craft to a field that would affect people's day to day lives. When I stumbled across exploration seismology as an undergraduate student, ...

Dusty galaxies with luminosities in excess of 10 L⊙ have been detected out to redshifts z ∼ 1 by the Infrared Space Observatory (ISO), and to higher redshifts using millimetre(mm)and submm-wave cameras on ground-based telescopes. The integrated properties of these more distant galaxies are also constrained by measurements of the intensity of the submm-wave background radiation. While it is gene...

A rotating dusty plasma apparatus was constructed to provide the possibility of experimental emulation of extremely high magnetic fields by means of the Coriolis force, observable in a corotating measurement frame. We present collective excitation spectra for different rotation rates with a magnetic induction equivalent of up to 3200 T. We identify the onset of magnetoplasmon-equivalent mode di...

The characteristics of arbitrary amplitude dust ion acoustic solitary waves (DIASWs) are studied in unmagnetized dusty plasmas whose constituents are cold uid ions, nonextensive electrons and stationary negative/positive dust particles. The pseudopotential approach has been used to investigate the structure of localized waves. It is found that, solitary waves exist in a definite interval for th...

This expectation is supported by the results of many observational studies with ISO, SCUBA, and now Spitzer, which provide evidence of strong evolution in number density and luminosity of dusty starbursts at z>1 (Elbaz et al. 2002; Chapman et al. 2003; Marleau et al. 2004; Yan et al. 2004; Le Floch et al. 2004). Therefore, high-z, dusty infrared luminous sources are believed to play a critical ...

In a laboratory, a two-dimensional complex (dusty) plasma consists of a low-density ionized gas containing a confined suspension of Yukawa-coupled plastic microspheres. For an initial crystal-like form, we report ideal gas behavior in this strongly coupled system during shock-wave experiments. This evidence supports the use of the ideal gas law as the equation of state for soft crystals such as...

Free convection effects and heat transfer due to a pulsating point heat source embedded in an infinite, fluid saturated, porous dusty medium are studied analytically. Both velocity and temperature fields are discussed in the form of series expansions in the Rayleigh number, for both the fluid and particle phases based on the mean heat generation rate from source and on the permeability of the p...
