"Photographing the Biggest Things in the Universe" by UCI Prof. Kevork Abazajian



Monthly General Meeting

Cosmological Large Scale Structure Surveys
by UCI Professor, Kevork Abazajian

The Sloan Digital Sky Survey was the largest optical survey of galaxies in our universe and it found 3-dimensional positions of approximately one million galaxies to a distance of 1.9 Gly (1.9 billion light years). I will describe the exciting results of this survey, its implications for cosmology, and the prospects for an even larger and deeper survey currently being designed for the future Large Synoptic Survey Telescope (LSST).

Professor Kevork Abazajian

Kevork grew up in the suburbs of Houston, Texas near NASA's Johnson Space Center. Inspired by the research of the space program, he went on to study physics and astrophysics at the University of Houston and the University of California, San Diego. He worked withe the Sloan Digital Sky Survey as a postdoctoral researcher and fellow at Fermi National Accelerator Laboratory and Los Alamos National Laboratory. Kevork continues work on large scale structure and dark matter as a professor at the University of California, Irvine.

The OCA has a general meeting held on the second Friday of every month* at Chapman University.

These meetings are free and open to the general public.

The meetings take place in The Irvine Lecture Hall with seating for approximately 250 people.

The Irvine Lecture Hall (located adjacent to the Hashinger Science Center) is near the south east corner of the campus
and the nearest cross street is East Palm Ave and North Center Street.

The meetings start promptly at 7:30 PM.

The basic agenda, with approximate times, is as shown below.

    Hmm, are y'all going to meet up somewhere pre-event so we can bother each other?

      Maybe you can volunteer to do that!

    Just received a note from the speaker, Dr. Abazajian, and he told me, "I got into cosmology because I thought and felt that it was fascinating that people are able to scientifically answer very much about the origin of our Earth, Galaxy, and Universe."

    I am so glad to see so many people signed up -- Orange County Astronomers is very popular! Make sure you clue your friends in on this event and make sure they are in the know.

    Just pass them this link:
