Although they contain hundreds of galaxies, and tremendous amounts of gas, their gigantic masses are dominated by mysterious dark matter. As the densest intersections in the cosmic web, galaxy clusters can help map the patterns of cosmic structure, and provide important clues about dark matter and the even-more-elusive dark energy.</p> <p>Says Erica: "I love looking at the universe, and in my work I use a variety of different types of telescope for research including large and small ground-based telescopes from around the world, the Hubble Space Telescope, the Spitzer Infrared Telescope, and the Chandra and XMM-Newton X-Ray space telescopes."</p> <p>The author of more than 100 refereed articles in professional publications and a regular invited speaker at international conferences in astrophysics, Erica is also widely known for her passion to bring the excitement of planetary science to the public and students in exciting ways. At the University of Colorado-Boulder's Fiske Planetarium, she has written and produced shows for the public on galaxies, cosmology and the history of science. She also teaches many of her astronomy course classes on campus, at the Sommers-Bausch Observatory.</p> <p>In 2011, Dr. Ellingson initiated a program whose aim is to support minority, first generation and rural students who are physical science majors. CU STARS (Science, Technology and Astronomy Recruits) offers internships, peer mentoring and academic support to students in their first years of university. She also leads an outreach program where these students return to their former high schools and underserved schools in both urban and rural Colorado, where the students lead classes on science topics and their own paths to becoming scientists.</p> <p>She is the co-author of a children's book, "Max Goes to Jupiter," which was chosen to be read aloud on the International Space Station for NASA's "Story Time from Space" program.</p> <p>Erica earned her Bachelor's of Science degree in Physics from MIT, and her Ph.D. in Astronomy from the University of Arizona, followed by postdoctoral fellowships at the Dominion Astrophysical Observatory, Victoria, BC and at the University of Colorado.</p> <p>Click <a href="" target="_blank">here</a> for more information.</p> <p> </p> </div> <span><a title="View user profile." href="/author/carlyo" lang="" about="/author/carlyo" typeof="schema:Person" property="schema:name" datatype="">carlyo</a></span> <span>Thu, 12/18/2014 - 15:06</span> <div class="field field--name-field-blog-tags field--type-entity-reference field--label-inline"> <div class="field--label">Tags</div> <div class="field--items"> <div class="field--item"><a href="/tag/nifty-fifty" hreflang="en">Nifty Fifty</a></div> <div class="field--item"><a href="/tag/usa-science-engineering-festival" hreflang="en">USA Science &amp; Engineering Festival</a></div> <div class="field--item"><a href="/tag/astrophysicist" hreflang="en">Astrophysicist</a></div> <div class="field--item"><a href="/tag/cosmos" hreflang="en">Cosmos</a></div> <div class="field--item"><a href="/tag/erica-ellingson" hreflang="en">Erica Ellingson</a></div> <div class="field--item"><a href="/tag/galaxy-research" hreflang="en">Galaxy Research</a></div> <div class="field--item"><a href="/tag/planetary-science" hreflang="en">Planetary Science</a></div> <div class="field--item"><a href="/tag/science-festival" hreflang="en">Science festival</a></div> <div class="field--item"><a href="/tag/science-speaker" hreflang="en">Science Speaker</a></div> <div class="field--item"><a href="/tag/space-exploration" hreflang="en">space exploration</a></div> <div class="field--item"><a href="/tag/stem" hreflang="en">STEM</a></div> <div class="field--item"><a href="/tag/stem-education" hreflang="en">STEM Education</a></div> <div class="field--item"><a href="/tag/stem-outreach" hreflang="en">STEM Outreach</a></div> <div class="field--item"><a href="/tag/university-colorado" hreflang="en">university of colorado</a></div> </div> </div> <section> </section> <ul class="links inline list-inline"><li class="comment-forbidden"><a href="/user/login?destination=/usasciencefestival/2014/12/18/exploring-the-origins-of-the-universe-with-astrophysicist-dr-erica-ellingson%23comment-form">Log in</a> to post comments</li></ul> Thu, 18 Dec 2014 20:06:52 +0000 carlyo 70654 at
