The Cosmology Interest Group is a sub-group of the Lincoln
Hills Astronomy Group.  We meet to
to provide a forum for
learning and
discussing cosmology: the study of the origin,
characteristics, and fate of the
universe or universes.  The CIG
provides an excellent opportunity for those who
have an interest in astronomy/cosmology to learn about, as well as to meet and discuss
with others having like interests.  Mathematics is purposely
minimized and is not
required to understand the concepts.

We usually meet on the third Monday of the month in
the Orchard Creek Fine Arts room at 6:45 PM.  But be sure to
the schedule below for any changes or additions.

Our Next Meeting

Monday March 18
in the Orchard Creek Fine Arts
room at 6:45 PM.   Ed Miller continues his lecture series on
Radio Astronomy with:

#11 Pulsars and Gravity:  A pulsar's spin begins with its birth
in a
supernova and can be altered by transfer of mass from a
star.  Learn how pulsars, these precise interstellar
clocks, are
used to confirm Einstein's prediction of gravitational
waves by
observations of a double-neutron-star system, and how
we pull
the pulsar signal out of the noise.

#12 Pulsars and the 300-Foot Telescope:  Humans constantly use
radio transmission these days, for everything from military
communications to garage-door openers.  How can scientists
which signals come from Earth and which come from
space?  Learn
how the 300-foot telescope, located in two
radio quiet zones, was built
quickly and cheaply.  It ended up
studying pulsars and hydrogen in
distant galaxies, and made
the case for dark matter.
