MagAO AAS Poster by Kate Follette

MagAO fans:  Did you miss AAS?  Or did you see our poster at AAS and want to see it again?  Kate had a lot of great conversations at the meeting (ADS link), and she has now posted her AAS 2013 poster as a PDF to our publications archive.  Here it is:

Well, we can’t believe it, but various team members are going to start heading to Chile next week for Comm-2!!  So we hope you enjoy this first taste of our results… and stay tuned for more soon!

MagAO Commissioning Day 30: Local minimum

Well, we are almost home… we made it to the Dallas airport. When we left in early November, the election had just concluded and I was still eating Halloween candy. Thanksgiving has come and gone. And now that we are back in the US, we are hit with the usual full-blown American Christmas with music, trees, and poinsettias overstimulating our tired traveling brains. We were trying to find the Admiral’s club in DFW and were talking very nerdily about MCMC algorithms to help us find it, and Laird said “I hope we don’t get trapped in a local minimum!” So here we are in a local minimum, and will be getting back to Tucson in a few hours. So let’s look at some highlights from the run.

The trip started with a solar eclipse on Nov 13th
We played some ultimate frisbee to unwind and for team comraderie.
The control room was packed -- but we never ran out of cookies!
We saw some beautiful sunsets
Saw some great vizzies
And had some touching advisor-student moments
We asked for more cowbell, and Simone wavefront-sensed by eye and figured out that we were phase-wrapping at the pyramid ... and that it could be fixed with a sign change in the interaction matrices
We made some pretty pictures
And made the highest angular resolution image in the universe -- Theta 1 Ori C in the optical. We later beat this by a few mas on the same binary. Better images are on the way.

Last quote of the run:

“Is it finally safe to say things around you two?” – Laird, to Jared and Katie.

MagAO Commissioning Day 28: Going home

The last of the MagAO team left LCO today. So long and thanks for all the spatial resolution! Since we didn’t all overlap, here are the 3 group pictures we took that captured everyone who came on the commissioning run:

MagAO Commissioning Day 26: Taking Clio and the ASM off the telescope

When you bring an expensive, delicate instrument to an observatory, you want there to be people like Juan Gallardo who put their full attention and serious effort into the procedures and operations for mounting and dismounting your instrument. Yesterday evening, we all met in the library/conference room, and Juan briefed us on the procedure to be taken today and tomorrow in removing Clio, the ASM, and the Nas from the telescope. Juan has been taking pictures and detailing every step, the whole time we’ve been here, and he put together a detailed and thorough document. Today the procedures were followed to safely and successfully remove the ASM and Clio from the telescope; tomorrow we will remove the Nas and store the ASM. Here is a picture of Juan:

So today we were back to a day schedule. Laird supervised Nas uncabling and ASM removal. T.J. supervised Clio uncabling and removal. And Juan managed the LCO crew, for a safe and successful instrument removal.

T.J. uncables Clio at the end of the night
Laird uncables the NAS in the morning
Laird and Pato disconnect the ASM
Felix and Nelson lower the ASM
Felix redies the ASM on its cart
This is what a non-adaptive secondary mirror (NSM ?) looks like. Felix and Nelson raise the f/11 secondary to the top of the telescope, now that our ASM has been removed -- to prepare for the next observing run.
T.J. and Kate pack up Clio electronics
Nelson, Felix, and Victor remove Clio on its cart
Our day was coming to a close as the sun set. Which was weird because sunset marked the beginning of our work for the past couple weeks!

MagAO Commissioning Day 23: Galaxies are …faint

Well, we tried out our faint guide star modes tonight. We locked on a 14th magnitude guide star in bin 3, and a 16th magnitude guide star in bins 4 and 5! We were getting down to 90 milli-arc-second PSFs in K-band, where diffraction-limited is 70 mas, while correcting fewer than 100 modes.

In this image we are locked on a 13th-magnitude guide star 24” from the galaxy (Clio image is below the finding chart).  We would like to thank D.M. for the quick reduction and feedback on our faint guide star work.  This is a big deal!  We were able to lock the AO system on the correct faint star in the field, keep the galaxy on the chip, and deliver a 0.25 arc-second PSF in 1” seeing and 1.7 airmass (about 35 degrees up from the horizon) on a faint guide star for off-axis science!

Quick reduction of our first attempt at imaging a galaxy while locked on a R=13 guide star 24'' away. Top: Finding chart. Bottom: Nod-subtracted Clio image (log scale, smoothed). In the upper right of each image is the guide star. The galaxy is seen at far left in the finder chart. The fainter star at lower center is recovered in the quick reduction. A more detailed reduction will be done to bring out the galaxy!

OK, look. This is a blog about science and engineering, and occasionally animals. But we’re tired. We’ve been here for a long time. It’s all we can do to keep up with our data logs and the infinite list of things to test and implement. So the rest of today is quotes:

The VisAO Data Reduction team trying to figure out their rotator angles:
Laird: “It’s 90 degrees”
Kate: “It’s 270 degrees”
Jared: “It’s 27 degrees”
Laird: It’s 7 degrees”
Kate: “It’s 97 degrees”
Jared: It’s 180 degrees”

Alfio: “Well now I know why that galaxies book I read was heavy on the theoretical modeling and weak on the observations. Galaxies are hard to observe!”

Laird: “Unlike with this galaxy nonsense, we will be able to see the young stellar disk right away!”

Laird: “Guys, just between you and me… and don’t put this on the blog… but …”

Jared: “It’s ok. We have another problem.”

T.J.: “We’re ballpark exactly on the sweet spot.”

Jared: “OK, T.J., I’m about to start saving data here.”
T.J.: “I’ve *been* saving data.”

T.J.: “Squinting is like binning.”

Laird: “High-order AO used to be 8×8”

Jorge: “The sun is rising! I have to close the dome!” (Pause… go in dome… close dome… come back to control room) “…OK, good, no fire!”
