Astronomer. I take images of extrasolar planets. Sometimes I make GIFs of them. Professor @NUCIERA and @NUPhysicsAstro
Joined August 2009
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'd like to see!

So excited to share this news!
Northwestern has joined the Giant Magellan Telescope's international consortium 🔭 Launching in the 2030s, @giantmagellan will be the world’s most powerful optical telescope—exploring the distant universe, including the search for Earth-like planets. https://t.co/VG3CCKlQLZ

Check out our new paper where we make the first C/O measurements of a protoplanet and compare it to the disk C/O!
I am excited to share my third paper of this year, and my first exoplanet paper with @semaphore_P , accepted to ApJL. We detected CO and water in the atmosphere of PDS 70 b using Keck/KPIC. PDS 70 b shows a stellar-like C/O ratio (!). Paper here:

Every other school should commission Cal students to do their gameday signs. These are top-tier.

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!

Calling all early Universe observers applying for postdocs: consider applying for the Brinson Prize Fellowship with @NUCIERA as your host institution! We have a great extragalactic group 🌌 and plenty of access to big glass! 🔭 Feel free to get in touch if you have any questions
A collaboration between The Brinson Foundation and @stsci, the Brinson Prize Fellowship program offers postdoctoral awards in observational cosmology. We are proud to return as one of eleven host institutions. Applications close on Nov 7. https://t.co/z5ENRUX1Wz

I did a podcast with Paul Duffell on imaging exoplanets, and now it's out! I had a lot of fun on it, and Paul was a great host, but he has zero social media presence, so I'm spreading the word. https://t.co/PJXPO8se11

For centuries, all that we have known about planets was confined to our own solar system, and its occasionally-changing number of planets (eight as of now). But in the past several decades, astrono...

Looking forward to seeing everyone showcase their new open source packages tomorrow!
The scenery of everyone working and discussing and creating some amazing work on their laptop screens at this meeting of creative minds is a sight to behold. I feel privileged to be a part of this community, first as a student and then as a TA. #CodeAstro at @NUCIERA

Northwestern is a host institution this year for the 51 Peg b fellowship! Happy to chat about possible research opportunities and link to other exoplanet/planetary science faculty here.
Northwestern is a new host institution for the Heising-Simons Foundation’s 51 Pegasi b Fellowship! The fellowship funds 3-4 years of research related to any area of planetary science (in our solar system and exoplanetary). Apply from Jul 9 - Oct 4: https://t.co/qdPpqcnVRL

Nice work led by @ChihChunHsu that expands the sample of benchmark brown dwarfs where we can get accurate abundance ratios using high res spectroscopy!
I wanted to advertise the two papers I led in 2024! The first one is HD 33632 Ab with Keck/KPIC, a late-L brown dwarf (~46 Mjup) companion (~20 au). We measured its spin, RV, and abundances, and compared the literature spins at the population level.

New beta pic b orbit movie!
This is Beta Pictoris b—a planet 12 times the mass of Jupiter—sailing around its star in a tilted orbit. Constructed from real data, astrophysicist Jason Wang (@semaphore_P)'s video condenses 17 years of footage, making it the longest time-lapse video of an exoplanet to date.

A Northwestern University astrophysicist has created the longest time-lapse video of an exoplanet to date. “We need another six years of data before we can see one whole orbit,” said Jason Wang, who led the work. “We’re almost there. Patience is key.” https://t.co/9gWWJ5vnaa
