Congratulations Dr. Logan Pearce!

It’s been quite a week for our intrepid veteran-turned-teacher-turned-professional-astrophysicist. The hardest part of the dissertation defense is usually scheduling it at a time all your committee members can attend, and this time was no different. In true Texan style, Logan lassoed her committee and roped them in to a defense in-person and online this June 11th, 2024.

Unfortunately, I was only able to watch the public portion of the defense from afar via Zoom. I also vicariously enjoyed Logan’s big day through the subsequent vignettes dropped context-free in our Slack’s #blog-ops channel.

(I think of these as a sort of wishful thinking. Posters wish a blog post into existence by posting things that might illustrate it. Well, who am I to deny them?)

Logan began with a title slide crammed full of the stuff she’s been working on these past five years:

She gave an overview of MagAO-X, for which she published the first ever peer-reviewed science paper using the instrument:

Gave the people what they crave (i.e. astronomical discoveries):

We got one, folks! (Actually, eight.) (Photo by Eden McEwen)

And let us know where we can find her in the near future:

Because we’ve never been sticklers about anything*, the party to celebrate Logan’s defense took place before the successful conclusion of the defense. Frankly, I’m gutted to have missed it. Fortunately, former-pastry-chef-future-Dr. Jay Kueny made Logan’s favorite pineapple buns in my stead. (No doubt with Melanie’s help!)

*Except label maker use, circus activities, and other important lab rules.

I’m told a pastry chef can make a pretty darn good pineapple bun (on the first try, too!)

Meanwhile, back in linear time, Logan was locked in a room(/Zoom) with four dangerous scientists and had to escape with only her wits. The labmates / COVID bubble-mates group chat—now scattered between California, New Mexico, Tucson, and New York—waited anxiously for word that Logan had surmounted her final academic trial.

Did she beat school?

Dear readers, of course she did.

The group chat accordingly recognized the ascension:

A full program of celebrations was called for, beginning with further chef magic from Jay.

By “chef magic” I am of course referring to how Jay just happened to have non-alcoholic Grand Marnier on-hand. (Photo by Eden McEwen)

The Cardboard Crowning of newly-minted Ph.D.s is a tradition as old as the academy itself. (Don’t quote me on that.) So, naturally, Logan was not about to get away without a hat pointing out what giant nerd just got all doctorfied.

From now on, you have to wear that getup to do astronomy. It’s the rules. (Photo by Eden McEwen)

Some more glamour shots of the extremely regal crown Eden made:

Celebrations for Logan continued that evening with beers at the site of her triumphs, with a special guest appearance by the Director of Steward Observatory and head of the Department of Astronomy at University of Arizona: Dr. Buell Jannuzzi.

What’s that he’s looking at? Well, there might be a blog post about that soon. Sure looks like there’s a dang viscacha in that instrument.

Song of the Day

Today’s song of the day is brought to you by the temperature delta between June in Tucson (high: 109ºF) and Michigan (high: 84ºF).

“Too Darn Hot” by Ella Fitzgerald (really, the definitive version, don’t you think?)

Bonus Hedgehog

I modeled this hedgehog in a Ph.D. tam for Logan with the intent of getting it 3D printed. Turns out 3D metal printing is, like, expensive. But it was too good to keep to myself.

Congrats to our 2024 Grads!

XWCL has a lot to be proud of this graduation season. Our best and brightest donned their funny hats and walked across their stages. What? You haven’t seen their defense blogs yet? Shhhh. The actual degree part, they’ll get there. Today is for celebrating!

First up was the Optical Science graduation.

We wish them the best of luck in their future work!

Congrats on the Academic pageantry, and we can’t wait to see you all defend!

A Toast to Warren, MSc, for the Miles Travelled

Cheers to mastery, mate!

On Thursday last week, Warren Byrum Foster of house XWCL, first of his name, Tzar of tubeless designs and the first picomotors, protector of PIAA lenses, cultivar of pineapple, breaker of linear shift-invariance, the unphased, and (most recently) Master of Science defended his thesis and restored peace and order to the 8th floor of the Optical Sciences building.

The public portion of the presentation detailed the many intricacies of the Phase-Induced Amplitude Apodization (PIAA) component of MagAO-X and I’m pretty sure I speak for more than just myself when I say that I learned a lot about the importance of this project for pushing the limits of the Magellan Clay telescope. Warren also had the foresight and kindness to distract us with tasty Mexican pastries and fizzy drinks while we awaited the good news during the “grilling” portion of the defense. We would all like to thank him for his work towards shrinking our inner working angle and furthering our long term science goals of becoming the best AO system in the world!

No windows were left with a cork-shaped hole, this clearly isn’t his first time…

Congratulations to Warren! Starting your grad school journey at the apex of the pandemic (Aug. 2020) and completing many of your core classes remotely and mostly solo was no easy feat (source: same cohort as me!) so extra kudos to you for sticking it out and finishing with a bang. We’ll definitely miss you and the positive vibes you bring; whether we’re on observing runs or just experiencing daily life on the UArizona campus. Here’s to the road ahead; may your hunts be fruitful and your arrows fly swift.

For now, Warren is continuing with the refinement of the PIAA setup with some fancy picomotors for finer control during operation. Further into summer, he is pursuing collaboration with the Roger Angel group to demonstrate his talents on the LFAST project.

A nice sunny day in the Summer of 1998 2023 provides the perfect backdrop for celebrating a successful Master’s defense on the 8th floor in Meinel.

For proper celebration shenanigans we found ourselves at 1912 Brewing Co. where we presented Warren with a super cool tee which he promptly and eagerly put on. (Thanks to Joseph for facilitating this!)

Song of the Day

The song of the day is an absolute classic and a known favorite of Warren. I chose this rendition because Ray Chen’s facial expressions while playing the violin more than make up for the lack of vocals here…!

Congratulations M.Sc. Avalon !

Advisor Jared R. Males and Avalon McLeod

Today another shining star of the MagAO-X team has defended! We all are so happy to announce that Avalon McLeod, after powering through a triumph of a thesis and defense, now has her Masters degree in Optical science!

Ready? Set. GO!

The story of Low Order Wavefront Sensing (LOWFS) was everything a AO control theorist could ask for. We got motivation from the 2020 Decadal Survey, multiple novel acronyms, AO diagrams old and new, PSF cleanup simulations, and stunning comparisons between lab and on sky results. Even those of us who saw the on-sky prowess of the LOWFS loop our own eyes were on the edge of our seats as she revealed how quantitatively well it performed our last run.

After the public portion of the talk, everyone but the defendee and the committee were asked politely to “Get out!” We all waited patiently for the committee to decide what we’ve felt for a while, that Avalon has earned the title of a Masters Degree.

(Well, we actually didn’t wait so patiently that we could help ourselves from sneaking a peak to see if they were done yet…)

The Optical Science’s building has glass in unexpected places, which mayhaps should be expected of an optics building

Among Avalon’s many skills is ceremonial un-corking (along with LOWFS-ing, nano-fabrication, hoodie fabrication, cameo printing, and a ccapella do-whops) and we celebrated!

Cheers to Avalon!
Now that’s a grad!

Congratulations Avalon from your MagAO-X family, observing runs and lab time won’t be the same without you. We wish you the best of luck as you go on to be an Astronomer for Draper in Boston! They’re lucky to have you.

“Shining Star” by Earth, Wind & Fire

Congrats Dr. Long!

Yesterday our very own Joseph Long ascended the hallowed steps of academia and become a PhD holder! The PhD defense at Steward begins with a 30 min public talk summarizing your thesis (summarize 5-6 years of work in 30 mins????), followed by a snake fight with just the committee, who then kick you out to decide your fate. Reception to follow in the venerated “Interaction Area” at Steward, the area in which we interact.

I am actually in California right now doing an internship at NASA Ames for the next 6 months. But Joseph is pretty much my best grad school friend and I have a lot of airline miles, so I hopped a quick flight for the festivities.

There’s the Catalinas in the window

The Public Talk

It was standing room only (not just because the only room he could reserve was too small…) as the audience sat in rapt attention for Giant Planets, Sirius, and Starlight Subtraction At Scale.

Not a Joseph joint without the fizzies
The plot every exoplanet talk is required by law to show.

A certain member of Joseph’s committee is well known for his love of orange Fanta at the telescope.

The Celebration

Of course he passed! While the OpSci grads get lovely sashes, a certain Steward postdoc-turned-faculty Kevin Hainline pioneered a slightly sillier tradition for Steward grads: an elaborate crown and cape featuring highlights of their research. If you follow this blog, you are well aware of the craftiness of some of our group members. So the troops were mobilized into action in true XWCL spirit (with heavy consultation with Kevin).

The cape is an astronomy fabric with gold letters (Avalon-printed) and plots from his papers with logos he made as well. The crown has a circus flair, and features bells on the ends, with a dumpster (I mean a MagAO-X with one too few doors on the top, oops) as the center feature. Around the base of the crown are hand-drawn (Eden-drawn) animals from the mission patches Joseph designed, each with their own crowns. Jialin also made some incredible art of Joseph, to be featured below.

Cheers
Jared’s first astronomy PhD student. He’s had all OpSci grad before this.
Three generations! Laird was Jared’s advisor.
Ewan Douglas was also a committee member. The other two joined remotely.

Joseph’s ‘rents! Two Drs Long + Dr. Capt. Mrs. Marta L. Gwinn-Long (Ret.) M.D. M.P.H.

I didn’t really get any pictures of the food! Jay Keuny’s partner Mel made incredible focaccia bread, Jay made amazing pistachio macarons, Maggie brought a lovely pie, and Jialin brought fun Asian flavor chips!

As a congrats gift, I made as Business Viscacha, or Businesscacha, or Biscacha. Behold Bizzy Biscacha:

He’s got some serious viscacha business to get to.

The briefcase opens and there are little letters in there 😀

Bizzy in his new home, attendin’ to business.

The Future

This summer Joseph is moving to New York City to begin a postdoc software fellowship at the Flatiron Institute. He’ll still be active with MagAO-X so keep an eye on this blog to follow his adventures.


The song of the day is HAPPY!
