Preliminary Results from an HST-NICMOS Paschen alpha survey of
the Galactic center: fine-scale filamentation in the ionized component
Mills, E.A., Morris, M.R., Lang, C.C., Wang, Q.D. and eight coauthors
Abstract:
We present preliminary images from a large-scale Paschen alpha
survey of the Galactic center region undertaken with NICMOS on HST.
Regions mapped in this field include the entire Sgr A complex, the radio Arc,
and the two starburst clsuters, the Quintuplet and Arches, as well as the areas
they ionize. The extremely high spatial resolution of these data over a field
that extends ~ 75 x 25 parsecs at the 8 kpc distance of the Galactc center
will allow for unprecedented study of the detailed morphology of this active
and complex region. In this preliminary study, we compare structures visible
in the Paschen alpha images to those in high resolution Radio images from the VLA.
In particular we concentrate on characterizing regions of highly organized, fine-scale
filamentation seen in the Pa-alpha images. The possible mechanisms underlying such filamentation
will be discussed.

 2007-2008 CFAO Professional Development Program Workshop
Santa Cruz, CA
November 30, 2007
This was an all-day workshop introducing the participants
to the idea of inquiry-based learning. We did a variety of
hands-on science activities, putting ourselves in the students place,
and discussed at length how these activities were effective,
and compared them to our own experiences learning and teaching science.
We also read some current science education literature, and saw examples
of the teaching experiences that last years participants had.

This was the second part of the workshop series, in which we designed an
activity that our team would then teach to a group of students at a later date.
To prepare to design an inquiry activity, we completed a full inquiry activity
ourselves. We also discussed further science education literature, and
toward the end of the workshop, we were able to concentrate on working with
our design group to
put together or modify an activity to give students a hands-on learning experience
in our field.

This was the third part of the workshop, a half day program
to prepare us for facilitating our inquiry activity. We covered
effective strategies, and role-played various scenarios that
might arise in the course of teaching.

Po'okela is a multi-week program designed for Native Hawaiian high school students.
I helped design and teach a week-long portion of this program that focused
on astronomy. My design group focused on one particular activity for that week -
an inquiry into stellar populations from which students would gain an understanding
of how the colors of stars relate to their other properties. More information on
that activity can be found here
