Science Abstract

First draft of Science Abstract:

We used archival Spitzer data to look for new young stellar objects (YSOs) in Cometary Globule 4 (CG4) in Puppis. CG4 is approximately 1300 parsecs and one of about 30 cometary globules in the Gum Nebula, many of which are known to be forming stars. These globules are pointed generally radially outward from the center of the Vela OB2 association, which is also forming stars. CG4 is dramatic in appearance, and that has brought it to the attention of both scientists and the public. Our team used archival Spitzer InfraRed Array Camera (IRAC) and Multiband Imaging Photometer for Spitzer (MIPS) data and 2 Micron All Sky Survey (2MASS) data, as well as optical data obtained by collaborators. We used infrared excess to find nine previously known YSOs and additional new YSOs in this region. We will primarily use infrared excess to find new YSOs. We used available data to attempt to determine legitimate cluster members, and to separate CG4’s YSOs from other objects with similar spectral energy distributions (SEDs). This research was made possible through the NASA/IPAC Teacher Archive Research Project (NITARP) and was funded by the Spitzer Science Center (SSC).

This research was made possible through the NASA/IPAC Teacher Archive Research Project (NITARP) and was funded by the Spitzer Science Center (SSC). rationale for my changes: occasional missing words/wordsmithing. the stuff about radially pointing is indeed true, but not strictly relevant to the abstract (tho' it's appropriate for the main body of the poster in the introduction). 'we will use' = lingering sentence left over i think from editing, since it is redundant with prior sentence. stuff about separating YSOs from contaminants absolutely true, but is implicit in the statement that we've identified YSO candidates -- of course we've attempted to weed out contaminants. there should be some text on that in the main body of the poster, though, for sure.

Edu poster 1

Here is the Draft Abstract for the Team Wisconsin Education Poster (Viv, WSD, WCBVI and Kevin - no Chelen, I haven't moved...) We welcome comments and edits.

Individuals with disabilities - specifically individuals who are Deaf or hard of hearing (DHH) and/or blind and visually-impaired (BVI) - have traditionally been underrepresented in the fields of Science, Technology, Engineering, and Math (STEM). The low incidence rate of these populations, coupled with geographic isolation, creates limited opportunities for students to work with and receive mentoring by professionals who not only have specialty knowledge in disability areas but also work in STEM fields. For this reason, Yerkes Observatory scientists, along with educators from the Wisconsin School for the Deaf, the Wisconsin Center for the Blind and Visually Impaired, Breck School, and Oak Park and River Forest High School, are engaged in active research with Spitzer Space Telescope scientists within the NITARP project. Our ultimate goals are threefold; to engage DHH and BVI students with equal success as their sighted and hearing peers, and share our techniques to make astronomy more accessible to DHH and BVI youth and to generate a life-long interest which will lead our students to STEM careers.

This poster tracks our work with a group of scientists from the Spitzer Science Center during the spring, summer, and fall of 2010. The group coauthored a poster on finding Young Stellar Objects (YSO) in the CG4 Nebula in Puppis. During the project, the students, scientists and teachers developed a number of techniques for learning the necessary science as well as doing the required data acquisition and analysis for publishing a poster for the American Astronomical Society. Additionally, collaborations were formed between students with disabilities and their their non-disabled peers to create multi-media projects. Ultimately, the projects created for our work with NITARP will be disseminated through our professional connections in order to ignite a passion for astronomy in all students - with and without disabilities.

The abstract looks fabulous to me. Great work, Team CG4! Do you need help in submitting?

Edu poster 2

(Mallory first author.)

Our team from Pierce Community College, Woodland Hills, CA, participated in the NASA/IPAC Teacher Archive Research Program (NITARP) this past year (2010). (NITARP is described in another poster, Rebull et al.) Our team worked with archival Spitzer, 2MASS, and optical data to look for young stars in CG4, part of the Gum Nebula; our scientific results are described in a companion poster, Johnson et al. In this poster, we describe more about what we learned and how we incorporated our NITARP experiences into the Pierce College environment. Students developed critical thinking skills and an ability to organize their data analysis and develop a mental "big picture" of what is going on in the CG4 region. The NITARP program is one of several "Active Learning" programs going on at Pierce, and the other programs are briefly summarized in this poster as well.
