Hello This is Michael Wallace( AKA Dub)
Summer 2003 at Sweet Briar:
I am working
with Dr. Grant Denn at Sweet Briar College, a private, liberal
arts college for women near Lynchburg, VA. Dr. Denn and I are attempting
to detect Circular Polarization in Active Galactic Nuclei(AGN). We are
looking at a set of four blazars and our main source is BL LACERTAE or
BLLAC. Dr. Grant Denn and Dr. Bob Mutel(Univ. of Iowa) used the VLBA(an
array of ten interconnected radio telescopes spread over North America
and managed by the NRAO) to resolve parsec scale structures such
as the core and jets in AGN's.
Circular polarization
or Stokes V is a measure of handedness of radiation from a light source.
Detection of circularly polarized light in AGN's will show that there is
a coherent magnetic flux flowing along the jet direction, or If the core
has circular polarization, linearly polarized light may have been converted
to circularly polarized light by Faraday Conversion(Macquart 2002).

Special Thanks to:
Dr. Dan Homan has helped immensly to simplify process
of Gain Calibration.
Dr. Denn and Robert Mutel for the data and NSF Grant
that brought me here
To A nice woman for first mentioning the intership
