Beautiful image!

Does anyone else see Van Leeuwen merchandise (from the ice cream brand) and think why there's merch for the Hipparcos astrometry catalog?

I'm apparently experiencing an adrenaline rush from a grad student in my group giving a talk at a conference I'm not even at?

Not at #HWO25 but had to watch the Youtube stream to see the coolest version of the HR 8799 orbit movie from @bmacastro.bsky.social

Every time I blink, Roman gets even closer to launch!

The 51 Peg b postdoctoral fellowship is out and Northwestern is one of the possible host institutions. Come join us! More information about the range of planetary astronomy research and other opportunities (like PI of Keck proposals) here: ciera.northwestern.edu/opportunitie....

Help us decide how to allocate ~2200 hours of Roman Space Telescope time! The Roman Coronagraph team is soliciting white papers to get community input on how to use our observing time (reminder, there is no GO call for the Coronagraph). If you need more details about the Roman Coronagraph.. (1/2)

We're looking to hire a director of operations for CIERA! Consider applying if you're interested in a position in astronomy where you enable others to do research.

Here's NASA astrophysics, if I read the president's proposed budget correctly. 🔭

*speechless horror* (Guys the NASA Exoplanet Archive is in this box. My job is in this box.)

Just coming down from the adrenaline rush of participating in the public comment period of my town's board meeting.

When schools on semesters are finishing up but you have 4 weeks left in the quarter.

Postdoc job Ad! Want to apply the latest technologies in laser combs and high-speed detector arrays for pushing heterodyne interferometry? Come to Ann Arbor to work with Prof Cundiff and me! Please repost this to help spread the word. Best to apply by Mar 31: apply.interfolio.com/162289

AAS has a helpful page for contacting your congresspeople on the status of astronomy funding in the US: aas.org/advocacy/get...

The 7th annual Other Worlds Laboratory (OWL) Exoplanet Summer Program is now accepting applications for our 3-week workshop in late July 2025. We seek to foster collaborations in exoplanet science with this workshop on the UC Santa Cruz campus. Applications are due March 15: owl.ucsc.edu/summer/

Very excited to share that I was selected as a Sloan Research Fellow! Really thankful to all my mentors, colleagues, collaborators, and my amazing research group. Wouldn't have been possible with all of them!

A cosmic love story? In a new study, CIERA graduate student Fulya Kıroğlu discovers that binary black holes formed in crowded star clusters align their spins - in a seemingly choreographed dance - before merging. Learn more: bit.ly/cieravalentine 📹: Jamie Lombardi / Allegheny College

Our second Picture an Astronomer public lecture -- in person (Chicago) and online Friday! Hear @astrokatie.com talk about the end of the Universe! More information + registration at pictureanastronomer.github.io/lectures/ 🔭🧪👩‍🔬

Final week to apply for the Code/Astro workshop! Come learn about open-source software development in Python.

Our Picture an Astronomer series starts in just over a week! Free to attend (in person in Chicago and online) and an incredible opportunity to engage directly with the scientists behind cutting edge astrophysics research. More info (including registration) at pictureanastronomer.github.io 🔭🧪👩‍🔬

The Roman Coronagraph team is soliciting input on what to do with 2200 hours on the highest contrast coronagraph ever flown! There is no open-time program, so fill out this survey on the technology demonstration and science that you think would be most interesting! docs.google.com/forms/d/e/1F...

Excited to share our interdisciplinary work on developing new methods to subtract off the glare of the star to reveal fainter exoplanets. We show in simulation that we can build a full optical model of JWST/NIRCam and generate images of the star to subtract off and reveal faint planets (1/3)

Want to learn how to make your astronomy code open source? The Code/Astro workshop is happening this Aug 4-8th at Northwestern! We typically get a strong demand so we ask those interested to fill out an application by Feb 1st. See Sarah's post below for details.

Duolingo is having me speak sentences about how parents-in-law tell bad jokes, while I'm at the in-laws.....

I actually followed through on a new year's resolution!

Black In Astro and @aascsma.bsky.social are hosting a free networking dinner on January 15, 2025, from 6-9pm at the 245th @aasoffice.bsky.social meeting in National Harbor, MD! Please express interest in attending by Dec 30 by using the QR code! 🔭🪐☄️. Link 🔗: forms.gle/ged5tKkYYTVS...

Northwestern press and Nature Astronomy research highlights nicely summarize our new paper on a baby planet’s atmosphere news.northwestern.edu/stories/2024... www.nature.com/articles/s41...

So excited to share the news that Northwestern is joining the GMT consortium! news.northwestern.edu/stories/2024...

Hey folks! Just popping in to announce that the full recording of the 2024 Code/Astro workshop is up on youtube. Playlist here: www.youtube.com/playlist?lis... Code/Astro is a week-long software development workshop for astronomers. More info about the workshop here: semaphorep.github.io/codeastro/

🔭🧪 Things that make me happy: This is the first image from Mars, taken July 1965. Why does it look like this? Because computers were slow and it was going to be hours before the computer processed it enough to make an image. The scientists and engineers were impatient. 1/5

You can learn about this discovery directly from Jocelyn Bell Burnell during one of our Picture an Astronomer events! More information at pictureanastronomer.github.io, including registration (in person and remote). For astrophysicists, come to our symposium, too -- all genders welcome! 🔭🧪👩‍🔬

I may have been thinking too much about optics recently because the first thing I thought of when I saw these truck lights is GMT pupil.

NASA is soliciting additional funded teams to join the Roman Space Telescope Coronagraph Participation Program. Help us demonstrate the technology to image habitable worlds in space! Happy to chat with anyone that's curious about getting involved. nspires.nasaprs.com/external/sol...

Check out our new paper on the first system where we can measure the C/O ratio in both a protoplanet and its disk!

Optimist: The cup is half full Pessimist: The cup is half empty Exoplanetary scientist: We've detected water in the cup!

Was I not paying attention or did Duolingo just add triple XP boosts? Is this a ploy to make me learn more?

I'm pretty sure I've seen each of these at SPIE this year.

Hello blue sky! Ready to catch up with friends and colleagues here, and share some my new science in the future 😁

Realized I never shared this when I was at OHP: this is the now-retired ELODIE spectrograph that discovered 51 Peg b. You can see the fibers that inject both starlight and calibration lamp light, the echelle grating that dispersed the light, and the detector that captured the spectra.

Let's see how the algorithm here likes coronagraphs. Can you see the small black dot at the center of this optic? (you might need to zoom in) That is used to occult the light of a star to see planets around it.

In addition, I hear there's a really interesting episode on exoplanets this year

I had the opportunity to make a pilgrimage to the Observatoire de Haute-Provence and see both the telescope and the spectrograph that discovered 51 Peg b. Super cool and awesome that the telescope is still detecting new exoplanets!

Northwestern is now a host institution for the 51 Pegasi b fellowship. Applications are due October 4. Happy to chat about the fellowship and/or opportunities here at Northwestern! www.hsfoundation.org/programs/sci...

Come for the software development, stay for the memes!

Apparently you can emoji react to outlook emails now???

Hello rayleigh scattering atmosphere!
