The primary objective of this session is to highlight ways in which identity can be construed and studied within science education, and to advance a discussion about how science education can embrace its civic responsibility toward students to help them appropriate science as a meaningful tool in their lives beyond school. The four papers reflect a range of(More)
Using a 100 ks XMM-Newton exposure of the well studied, low black hole mass (M BH = 1.9 × 10 6 M ⊙) Narrow Line Seyfert 1 NGC 4051, we show that the time evolution of the ionization state of the X-ray absorbers in response to the rapid and highly variable X-ray continuum constrains all the main physical and geometrical properties of an AGN Warm Absorber(More)
1. Introduction As the panel on Planetary Systems and Star Formation (PSF) is fully aware, the next decade will see major advances in our understanding of these areas of research. To quote from their charge, these advances will occur in studies of " solar system bodies (other than the Sun) and extrasolar planets, debris disks, exobiology, the formation of(More)
Cosmic plasma conditions created in an Electron Beam Ion Trap (EBIT) make it possible to simulate the dependencies of key diagnostic X-Ray lines on density, temperature, and excitation conditions that exist in astrophysical sources. We used a microcalorimeter for such laboratory astrophysics studies because it has a resolving power .1000, quantum efficiency(More)
