A
Study of the Spiral Galaxy
M101
Katrina Banks and Issac Lister
Elizabeth City State University
We present the results of summer research
on the spiral galaxy M101. We have
processed and examined images of this
object taken from the ground using
narrow-band interference filters centered
on wavelenghts of several bright nebular
emission lines. Our study included
examining emission from both high and
low ionization ions, O++ and N+ respectively.
The presence of HII regions in the
arm as well as the ionization structure
across the galaxy is discussed.
The authors gratefully acknowledge
funding provided by NASA-MUSPIN to
Elizabeth City State University (NCC
5-121) and South Carolina State University
(NCC 5-116) and NASA-URC to Tennnessee
State University (NCC 5-228). Additional
funding was provided by the Office
of Naval Research (N00014-99-1-0990).
Investigations
of a Toy Model of Dark
Matter Clustering
Shayla Banks, Vincent Davis,
Elizabeth City State University
The growth of dark matter clusters
in the early universe is investigated
by using a two-dimensional toy model
developed by Krauss and Starkman.*
The model is implemented in the Mathematica
software so that the variation of model
parameters can be understood visually.
Effects investigated include expansion,
growth of the horizon, and free-streaming.
Because dark matter is thought to be
the seeds for the formation of galaxies,
the correlation function for a set
of model parameters is calculated and
compared with that determined from
an actual galaxy catalog.
