Analyzing Astronomy Data with JS 9 on the Web

Event Description ASTRONOMY, Division C DESCRIPTION: Teams will demonstrate an understanding of Star and Galaxy Formation and Evolution A TEAM OF UP TO: 2 APPROXIMATE TIME: 50 minutes EVENT PARAMETERS: • i. a computer/tablet of any kind a three-ring binder; or, • ii. two computers/tablets, of any kind or two 3 -ring binders. • b. If two ring binders are used they may be of any size and the information contained should be attached using the available rings. The information or pages may be removed during the event. Sheet protectors and laminated sheets are allowed. • c. Each team may bring two calculators of any type (stand alone or computer app) • d. Participants using computers/tablets as a resource should have all information stored so that it is available to them offline. However; teams may be accessing a dedicated NASA image analysis website to answer js 9 questions. For js 9 questions, supervisors must provide an alternative (e. g. proctor-supplied computer or screen shots) for teams that did not bring a laptop/tablet.

Using information which may include Hertzsprung-Russell diagrams, spectra, light curves, motions, cosmological distance equations and relationships, stellar magnitudes and classification, multi-wavelength images (gamma-ray, X-ray, UV, optical, IR, radio), charts, graphs, animations and js 9 imaging analysis software, teams will complete activities and answer questions relating to: a. Stellar and galactic evolution including stellar classification, spectral features and chemical composition, luminosity, blackbody radiation, color index and H-R diagram transitions, neutron stars, stellar mass and supermassive black holes, Type Ia supernovas, galactic structure and interactions, quasars, active galactic nuclei (AGNs), galaxy clusters and groups of galaxies, gravitational waves, gravitational lensing, dark matter and energy, warm hot intergalactic medium (WHIM), and the Cosmic Microwave Background (CMB). b. Use Kepler’s laws, rotation and circular motion to answer questions relating to the orbital motions of galaxies; use the distance modulus, Type Ia supernovas, Hubble’s law and redshift to answer questions about Hubble’s constant and the recessional velocities and distances to galaxies. c. Identify and answer questions relating to the content areas outlined above for the following objects: SN UDS 10 Wil, NGC 2623, GRB 150101 B, JKCS 041, MACS J 0717. 5+3745, MACS J 1149. 5+2223, Bullet Cluster (1 E 0657 -56), H 1821+643, The 3 Quasars (152156. 48+520238. 5, 153714. 26+271611. 6, 222256. 11 -094636. 2), GOODS-S 29323, H 2356 -309, PSS 0133+0400 & PSS 0955+5940, GW 151226, M 87, 3 C 273

National Astronomy Event Supervisors: Tad Komacek – tkomacek@gmail. com Donna L Young – dlyoung. nso@gmail. com Connor Todd – cepheidwatch@gmail. com Event Clarification - https: //www. soinc. org/division-c-events js 9 Resources & Suggestions for Event Supervisors: 1. This webinar will be posted on the Chandra website (PPT on the NSO website) when completed. 2. An in-depth js 9 3 -part Manual is being written and when completed will be posted on the NSO website, 3. Three Astronomy invitationals are being held Sept-Nov and these tests, which will contain js 9 questions will be posted on the NSO website after the competitions are completed. All resources and materials, including tests and answer keys are posted under Event Supervisors.

4. As usual, the MIT and Golden Gate invitational tests with answer keys will be posted on the NSO website under Event Supervisors. 5. js 9 questions are not recommended for regionals. 6. Screen shots or on-line analysis can be used for invitationals, regionals and states. 7. A js 9 question with both on-line and screen shot versions will be available from the NSO with a request for state directors only that can be used at the state level. 8. At nationals we will have laptops available for those teams who bring two 3 -ring binders and no laptops. Otherwise teams can use their own laptops. We will bring screen shot versions if there any difficulties with the internet. 9. We will be experimenting with the invitationals the A-Team members are supervising during the fall and winter (2019 -2020). 10, And now I will introduce Pam Perry, a high school physics teacher who has used the DS 9/js 9 with her students for several years.
