MagAO-X 2023A Day 8: Daisy, Daisy

Day 8 saw the arrival of two colleagues and one hefty tarantula.

Despite having to negotiate the Atlanta airport with speed, they made their connection to Santiago, where they obtained their Mountain Names: Iden and Jackke.

Nobody captured the exact moment they alighted from their servicio especial van, and they’re extremely asleep right now, so you’ll have to trust us: they’re here.

Today we crammed in quite a lot of science and engineering before shutting the instrument down for the night before its Friday morning trip up to the telescope platform. We also wrap it up to prevent heating and intrusion by dust.

Anyway, all that means: tomorrow we’re doing the thing! This means we wake up for breakfast, make approximately 100 trips back and forth between the summit and the almost-summit where the cleanroom is, plug a lot of things into other things, and then do astronomy until it’s time for breakfast again.


As the only graduate student present who has been on a MagAO Classic run, it fell to me to implement the speech-synthesis ops concept that Jared has long coveted for MagAO-X. (Only so many people can crowd around MegaDesk, but everyone in the control room can hear “loop is closed.”)

Speech synthesis has changed a lot since Jared was a grad student, and professional-grade deep-learning models are surprisingly good these days. Of course, the budget for this was $0.00, so I used OpenTTS. OpenTTS lets you sample a wide variety of synthesis packages with a common API, and I had the container running on AOC (that’s our Adaptive optics Operator Computer) in a few minutes.

The next challenge was to hold auditions. For my auditions I imagined some things MagAO-X might want to say, and gave them to the various models: “Target changed. High-order loop closed. Data saving started. Loop is open. Smoke ’em if you got ’em.”

The previous-generation models were there for comparison, and sounded like absolute butt:

On the plus side, espeak was one of the only included engines with a non-US/non-UK English voice:

Island vibes aside, the synthesis was just not that good. I kept looking. This MaryTTS voice seemed all right:

Just one small problem: Maggieo-X is clearly not male. This voice clearly is. That simply won’t do. How about this from Larynx?

Not bad. But are we sure Maggieo speaks English?

I also ran the Dutch voices past Sebastiaan Haffert, local Dutchman:

Verdict?
“They’re all… very Flemish.”
“Is that bad?”
“No, they’re just very… soft.”

It’s true. The characteristic throaty “g” of the true Dutchman was let down by these synthetic voices. Just click the speaker icon on here to have Google’s model read the same to you. See?

Anyway, auditions continue, but I have a pretty good idea of who will be narrating our ops tomorrow night. Until then,

“Good night. We’ll see each other tomorrow.”

Song of the Day

Okay, maybe when I posted Bring Me To Life and then Jared had Korn it started a bit of a nu metal trend, but in the end it doesn’t really matter.

I don’t play many video games, mainly because I am usually in the business of telling computers what to do, and therefore really resent them telling me what to do. One recent exception was Sayonara Wild Hearts, which is incredible. More of an album-length interactive music video than a “game,” I guess, but anything that includes:

  • firing heart-shaped projectiles
  • from your motorcycle
  • at a three-headed robot dog
  • as a metaphor for overcoming heartbreak
  • (narrated by Queen Latifah)

has to be good. And, of course, the music complements the v i b e s perfectly. (And is strongly inspired by CHVRCHES, no doubt.)

“Dead of Night” by Daniel Olsén, Jonathan Eng, and Linnea Olsson

For some reason, nobody’s taken the unadulterated audio and overlaid it on gameplay for a ready-made music video, but if you can ignore the dings and bleeps this should give you some of the flavor.

Bonus Tarantula

This little guy took up residence on Avalon’s door this evening, requiring XKID xpert Noah Swimmer to remove him.

MagAO-X 2023A Day 7: Back for more

Warren and I took different paths to Santiago but were able to meet up at the infamous Starbucks in the domestic terminal.

The tradition of name swapping continues. We lost Warren today, but we are quite happy with his replacement Juan.

We continued our journey onwards took the plane to La Serena and then the bus to the observatory. It took me only 78 days this time to come back to LCO and it feels like I never left. Like a certain PI said: “home is where the wifi connects”. This rings very true for LCO.

Our days immediately started with work due to tight schedule because of the many projects that we are doing at MagAO-X. Warren dived into the clean room to assemble his new monstrosity to mount the PIAA lenses. And, I started aligning a laser into a single-mode fiber. This was necessary to take some calibrations to improve the reduction of data from our last run. Its quite tricky to get enough light out of a single mode fiber when not all axis of your mount work. After spending about 2.5 hours I finally got enough light through and I was able to finish my calibrations. I finished at 2 AM! However, the night sky at that time is always amazing.

The milkyway at LCO.

During daytime we were able to make big strides on the integration of the camera software of VIS-X IFU and MagAO-X. This will hopefully mean I won’t have to leave my laptop beneath the instrument again during the observations.

I choose a song from Bon Jovi which is one of the few artists I have actually seen IRL. This was part of the Royal Dutch Beach concerts almost 10 year ago.

MagAO-X 2023A Day 6: Got The Life

I’m a C++ programmer, which means I’ve been here for a week. Consequences include I’m doing laundry already, and I have no idea what day of the week it is (that might be a memory leak joke).

Sebastiaan and Warren arrived today, and immediately started tearing the instrument apart (as expected).

The XKID crew warmed it up today to inspect some things on the inside, which gave us an opportunity to go visit and see the guts up close.

Noah Swimmer likes to dance with his PhD project.
Ben explains it all to Laird, Joseph, and Avalon, while Noah and Jeb (he’s back there) work.

We’ve been seeing these Neotropical Stick Grasshoppers a bunch. This one was flexing for me after lunch:

It’s a grasshopper?

The machine shop sink outside the cleanroom has been decorated:

Not as desolate as you’d expect

I think one of our cleanroom friends overdid the sun bathing today, and was a little out of it at sunset.

sleepy viz
oh, yawn, are you taking my,yawn, picture? (I didn’t observe actual viz yawn)

As in all things in life, there are ways to separate the people who have really made it. The signs are there if you look:

How to know that one is a Certified Big Deal.
Alpha Cen-rise. The Southern Cross is 60% up and 25% over. Follow the short arm down to the first star, then go one more.

So you could title my series of songs “concerts I went to with my best friend Ben.” Here we switch from country to hard rock and metal, and this will be the first in a sub-series about a specific show. We went to a concert in Omaha to see a band (coming up, no spoilers here), for which there were two openers. The first opener was a total surprise, that no one there had ever heard of (we didn’t even know there was going to be a first opener). I’m not trying to be that guy, you know, cool before it was cool.

They come out, and I’m grumpy “who the F is this?” And then Ben looks at me and says “are they . . . do they have … bagpipes?”. And then it was on, into the mosh pit we went. The band was KoRn (I can’t do the R right here). Awesome show. Ben still has a dollar bill signed by Jonathan Davis in the CD case he bought that night. KoRn got huge shortly after and we get to say we saw them when.

So here’s my favorite KoRn song:

Got The Life by Korn

Update: I am a big enough deal that I travel with my own personal tech support. Thanks to Joseph I can now write KoЯN.

MagAO-X 2023A Day 5: Aligned and well

Today Laird and I continued alignment on MagAO-X with some frustration but ultimately success. The MKIDS team has provided us (among other additions) with a new dichroic that has made a nice addition to the instrument.

Keeping up with MagAO-X fashion to consistently sneak new things onto the table in fun mechanical ways!

Occasional robotic and sometimes chipmunk-like sound bites were heard around the cleanroom today, indicating that MagAO-X may be soon equipped with some auditory additions…

Laird and I (now sometimes referred to as Lardy and Eva) will be freed from our bubbles tomorrow as long as we pass our nose-swabbing tests in the morning. This means I can very soon visit my good friend the espresso machine! Non-bubbled members got to enjoy a visit from Carlos the culpeo at the lodge.

Perhaps looking for leftovers.

Not to worry, vizzy activity near the cleanroom has kept all members happy – bubbled or not.

Some of my favorite mountain dwellers were spotted by the PI today as well.

My kind of caravan.

Group members Warren and Sebastiaan are en route to LCO so we will have new familiar faces arriving soon!

Song of the day is brought to you by Melanie:

This song was introduced to me by both my dad and aunt in conjunction I suppose. Back in the days of cds, my dad’s sister burned a cd for him with some of his favorites and songs they had shared a likeness for growing up together. This charmer made it on that cd and was played nearly every morning by my dad – quite loudly through the house – in order to encourage my brother and I out of bed to get to school on time. On that same cd you can find the song I was named after (I’ll let you guess the title) by Roxy Music. Both of these have found their way onto my personal playlists, and sometimes help me get out of bed in the morning to this day.

MagAO-X 2023A Day 4: Never go Full Quantum

For better or worse, the original MagAO-X NSF proposal included funds to bring a brand new type of camera to the party – a superconducting sensor array that runs at 0.1 degrees above absolute zero. The big idea is that these arrays can tell you the energy of every photon that hits them, without the pesky noise sources that typically degrade astronomical images. These detectors, called MKIDs, are also VERY FAST, which lets you play all sorts of fun games to pick faint sources out from the background starlight that MagAO-X hasn’t bothered to deal with.

This camera, called XKID, was originally meant to just be the DARKNESS instrument from Palomar moved down to Magellan. However, DARKNESS uses liquid helium for cooling, and that has become outrageously expensive, so we actually took the old ARCONS fridge and did a massive upgrade. This resulted in the beauty you see above.

XKID will extend the wavelength range of MagAO-X out to 1400 nm (J band), allowing astronomers to look at older, colder exoplanets, and also provide low resolution spectroscopy and eventually focal plane wavefront sensing to help MagAO-X clean up all the meshugas the damn atmosphere gets up to.

Jeb Bailey, Noah Swimmer, and I are in the process of getting this bad boy cooled down and tuned up, which is always an adventure. Later in the week we will mate it up to MagAO-X (for the first time!) and hopefully see stuff… Stay tuned!
