AO Summer School Day 1: Closing the loop on California mysteries

I am generally horrible at finishing things, and there were so many stories to tell about good times in Santa Cruz that I never finished my blog post. I started writing during the first night of the workshop, but didn’t return to tell the stories of renting a bike and spending afternoons enjoying rides in the countryside. A late night guilt trip during the 2023A run from *nameless parties* has made me choose to post what I’d written in August.

While sipping coffee in the shade of towering redwoods this afternoon, Eden ran up behind me and hurriedly asked if “I’d seen Jared’s message on Slack”. When I said I hadn’t, she said “good – Jay and I think that you should be the first one to write a blog post about the workshop. This news set off alarm bells and self-doubt that we’d taken enough photos to justify the lofty precedents of previous posts. The subsequent rush to backlog material might lead to an uneven post, but hopefully presents an accurate picture of California life.

Flying into San Jose airport at nighttime feels like a glimpse into the future: either utopian or dystopian depending on personal preference. Terminal walls are adorned at fifty feet intervals with large screens proclaiming the latest software accomplishment from interminable corporations. These advertisements can be generally ignored by bleary, midnight eyes until passengers are funneled out through automated security doors and greeted by an LED mural twenty feet tall, bright red and devoted to Intel alone. Sleepy wrinkles in passengers faces are filled with the bright light as they shuffle into escalators going to a similarly lit baggage claim. It feels like some combination of Blade Runner and Fahrenheit 451.

My personal history with California has been checkered at best: past work trips to San Diego have imparted a unique claustrophobia of being surrounded by endless suburbs and six lane highways; of traveling for hours and never leaving the city. With that background, I gave the most profound sigh of relief in my Uber when I was greeted in Santa Cruz not by strip malls but instead by a deer, silently walking through the moonlit streets [not pictured – sorry!]. I have since learned that it was part of a healthy resident population on the university campus.

The campus is a beautiful setting for a conference, and the cool breezes from the ocean are a welcome break from Tucson heat. The lectures are widely succeeding at proving a strong background to the wide-ranging field of adaptive optics. I can appreciate the challenge in planning a curriculum for 29 students with wildly different backgrounds and experiences. The first day was a broad introduction to adaptive optics in general – I think that most of the class pitied the grad student who was asked to deliver a briefer on geometrical optics and third order aberrations in one hour. Several talks stuck out on the first day though, especially Phil Hinz’s overview of wave optics and Rebecca Jensen-Clem’s lecture on atmospheric turbulence. Being used to picking up the concepts on the fly, it was very helpful to reestablish the source of useful rules of thumb like r0 and t0 scaling with wavelength. The workshop is unique in bringing people from such a niche field into a room together.

I went to bed after this, and thus ends the written memory of the AO Summer School. Santa Cruz has wonderful bicycle infrastructure, and immediately upon arriving I began making inquiries about how to rent a bike. After being disappointed by several foundering startups attempting to revolutionize the bike-rental industry, I finally found a wonderful beach cruiser that I named “Black Beauty”. The shop owner – who sounded exactly like what you would imagine someone who runs a bike shop two blocks away from the beach would sound like – told me “don’t ride off road, or at least if you do then clean it afterwards because we don’t have a hose here”. I took this liberally, and had a blast over the next few days exploring the steep hills of Santa Cruz after the workshop finished in the afternoons. Here are some fun photos from these rides.

Song of the conference

There are so many songs about California but time spent walking around the Giant Sequoias of the campus kept reminding me of this lesser-known one.

MagAO-X Takes Montréal Day 5: La conférence d’espionnage

It is extremely illegal to smuggle Andean mammals of the high desert into downtown Montréal, but I have always wanted to try poutine, and MagAO-X already got me as far as Tucson anyway.

At the border, I tried to explain I was going to the SPIE conference but I’m not sure Google Translate was working.

Today, Laird and Lauren both gave their talks, which I’m sure were lovely, but I honestly had trouble staying awake after the long flight from Tucson. Here’s a picture of me trying to pay attention to a conversation between Olivier, Jared, and Laird.

It was worth the price of the ticket just to see all three in person, again. See you in November, señores!

MagAO-X Takes Montréal: Days 3 and 4

*A new grad student has entered the chat.*

Hello Blog! I’m Eden and I’ll be joining the MagAO-X team this fall as an OpSci grad student. This SPIE I’m presenting my wavefront profiling work on imaka, a GLAO demonstrator,  but I’ll be joining the high contrast crew in no time.

Happy to report that I survived my Wednesday poster session.

This conference is much more exciting, informative, and thrilling than any of the online approximations the last two years. So far, as a first time SPIE-ian, I think I could summarize the experience so far as a mix of:

  • Cutting edge talks illuminating the future of our field and fully inspiring me to start over my research from scratch.
  • Celebrity Spotting:
Jared spotting Olivier Guyon in the AO session.
  • Stalking the exhibition hall for the elusive free coffee and rumors of the best freebies:
The Dutch booth had 400 units of a LEGO JWST model. They ran out in a day and a half.
  • Extreme pride at the progress of the field, the creativity of research, and my own ability to understand some of it.
  • Crashing at 3pm and making use of the food and resources in the community lounge networking space.
Leftover beads from diversity sessions means an opportunity.
  • Rallying for the 6-8pm poster session, and being surprised when the admin needs to increasingly aggressively flip the lights to force us attendees to leave.

Over the last two days, many MagAO-X talks have graced the stage of the the AO talk session. The group is looking very good up there.

Laird presents his talk on holographic dispersed fringe sensor.
Sebastian presents on behalf of Meghan O’Brien.

We’ve also had a fully stocked schedule of posters, some of which *cough Sebastian* had an ever present line.

Joseph explaining computer optimization to the next generation.
Maggie presenting on GMagAO-X’s DM optical design.
Noah Swimmer from UCSB presented an MKID camera for use behind MagAO-X 
Sebastian’s poster before the rush.

A very special session on Wednesday paid tribute to a titan amongst AO, David L. Fried of the Fried parameter and the Fried geometry who passed away in May. One of his close collaborators gave a history of his career which ended up being a historical overview of the field itself. As a younger scientist, it was humbling to see how much one man had contributed to the science I work with daily as well as how many around had gotten to work with him directly.

Of note, the memoriam presenter was just as excited as the rest of us to receive the speaker gift for the AO session:

“We r-not limited by seeing” with a back of the Fried Geometry

Hope everyone can stay strong through the last two days of this intellectual marathon!

MagAO-X Takes Montréal: Meanwhile back home…

While the whole group is living up up north, those of us left behind in the sweltering heat and humidity of Tucson in July got a treat today:

Everyone safe and sound in the loading dock staging room. The big white box in the back is MagAO-X, the foreground is the electronics box, and the grey box is our control computer.

That’s right, that’s MagAO-X back home all safe and sound and looking none the worse for wear from her journey home from Chile! Delivery was kind enough to happen when literally everyone from the group is in Montreal or otherwise elsewhere, except moi and undergrad researcher Roz Roberts.

Your’s truly and Roz, dripping sweat

Folks it was a rough one. After about 30 mins of watching the crane and maneuvering the dollies in the 6 million degree heat and 5000% humidity (I measured), I was pretty wiped. And all we did was move it off the loading dock into the staging room. Unpacking comes next week, so stay tuned for the next update!

I attempted to replicate Joseph’s excellent video montages to middling success:

Apologies for the vertical video, I didn’t realize my error until it was too late. I will never apologize for hamster dance.

The real heroes in the sweltering heat while I take video.

Hope y’all are enjoying the cool Canadian weather.

MagAO-X Takes Montréal: Day 2

It’s only day 2 of the SPIE Astronomical Telescopes & Instrumentation Conference and already lots of interesting talks, lunch & learns, and posters are underway.

Dr. Richard Dekany gave an interesting talk on SIGHT, the Palomar 5m telescope LGS AO system, and highlighted the support of our very own Sebastiaan Haffert and Meghan O’Brien on the Optical Differentiation wavefront sensor.

The Equity, Diversity, and Inclusion (EDI) Lunch & Learn brought up interesting points about international differences in approaches to EDI. There are more similar events and networking events throughout the week in room 514!

We supported fellow optical sciences grad student, Kevin Derby, from the UArizona Space Astrophysics Lab during his fantastic talk on pinwheel segmented primary apertures.

Since this lab just loves when things are “in-phase”, several of us attended a talk on the phasing of the James Webb Space Telescope by Scott Acton. He had some thoughtful words on his next steps as a scientist, “And that’s how you align the telescope. Now I need another job.”

Scott Acton presenting his talk

On theme with space telescopes, we are finishing the night with UASAL graduate student, Jaren Ashcraft, presenting his poster on the Space Coronagraph Optical Bench – SCoOB.
