Inflation

The Cosmology Interest Group is a sub-group
of the Lincoln Hills Astronomy Group. 
Meetings
are
in the form of a lecture or video series, focusing
on
some aspect of cosmology; followed by a spirited discussion.  There is no need to be proficient in math
or physics formulas.  We try to keep things as simple
as possible, so everyone can grasp the topic being presented.  This is a fun group with lots very smart members to answer just about any questions you

may have about the cosmos.

Our Next Meeting

 
There will be no meeting in July.
Monday, August 19
in the Orchard Creek
Fine Arts room at 6:45 PM,  Ed Miller continues
his series on radio astronomy with lectures:


#19 A Telescope as Big as the Earth
    Learn how astronomers use very-long-baseline
interferometry (VLBI) with telescopes thousands
of miles apart to essentially create a radio telescope
as big as the Earth. With VLBI, scientists not only
look deep into galactic centers, study cosmic radio sources, and weigh black holes, but also more
accurately tell time, study plate tectonics, and
more.  Right here on planet Earth.

#20 Galaxies and Their Gas
In visible light, scientists had described
galaxies as island universes.  But since the
advent of radio astronomy, we've seen galaxies connected by streams of neutral hydrogen, inter-
acting with and ripping the gasses from each other.  Now astronomers have come to understand that
these strong environmental interactions are not a secondary feature.  They are key to a galaxy's
basic structure and appearance.
