My first, first author paper is now on arXiv! We investigate how different parameterizations can bias L dwarf retrievals. The headline? We need non-uniform-with-pressure abundance profiles for prominent rainout species! arxiv.org/abs/2301.08258

"That lets us somatically experience a future beyond what exists now, a future we all actually want. Joy in the present makes joy in the future seem plausible. And that, too, is hope."

.@macleans: ‘Heated Rivalry’ Is Anti-Dystopia Art “‘Heated Rivalry’ offers a cinematic universe that references our own, but casts an alternate vision of a world that’s possible — a world of pleasure, mutuality, humanness, intimacy, creativity and joy. (…) It has broken through the onslaught of pop culture visions that make dystopia’s cynical, joyless futures seem inexorable precisely because it is a piece of art that not only shows us, but allows us to feel that another world is truly possible. That lets us somatically experience a future beyond what exists now, a future we all actually want. Joy in the present makes joy in the future seem plausible. And that, too, is hope.” 🔗 macleans.ca/culture/heated-r…

We found methane in emission on an isolated brown dwarf, which may indicate that it has an aurora! I'm so happy I got to be part of this team lead by @jfaherty. I learned a ton and it has me super excited for all of the unexpected discoveries yet to come with JWST!
NASA Webb Telescope
@NASAWebb9 Jan 2024
Brown dwarf W1935 posed a mystery. Webb found that methane in this object’s atmosphere was emitting infrared light, despite no obvious energy source. Using clues from our solar system, scientists found a possible explanation in aurorae: go.nasa.gov/3HddFPe #AAS243
An artist concept portrays a round, gaseous object on a black, star-filled background. The object, a brown dwarf, occupies the right half of the image. It is various shades of dark blue and is streaked with undulating horizontal bands that encircle it, much like the planet Jupiter in our solar system. It is tilted to the right and toward the viewer so that one pole is completely visible. The pole is circled by a curtain of red representing an aurora.

Graphic design is my passion.
A screenshot of a text message thread with my exhausted boss. It reads: Boss: Before you log off, we need to tweet a reminder about Labor Day Fire Safety. Me: Prevent these flames or we'll call you names. Boss: Not this again. Me: Watch your pile or we'll get hostile. Me: Illegally start a fire? Your situation'll get dire! Boss: Can you please just make a cute graphic or something? Me: On it.

Hey Astro Tweeps. I'm looking for input/advice on LGBTQIA friendly Astro grad programs in the US or abroad, especially those that are trans friendly. Happy to hear from anyone, but I'm particularly interested in hearing from grad students currently/recently at these programs.

We celebrate the life of Nichelle Nichols, Star Trek actor, trailblazer, and role model, who symbolized to so many what was possible. She partnered with us to recruit some of the first women and minority astronauts, and inspired generations to reach for the stars.

UT Astronomy graduate student Rebecca Larson chatted with Quanta Magazine about some of the amazing things JWST has already seen just a couple of weeks into its science mission:

@QuantaMagazine25 Jul 2022
Just weeks into its mission, the JWST is unleashing a fire hose of valuable data. “It’s better than I imagined and it’s only the beginning,” said astronomer Rebecca Larson (@SaturnsWings). @Astro_Jonny reports: quantamagazine.org/two-weeks…

Two Weeks In, the Webb Space Telescope Is Reshaping Astronomy | Quanta Magazine

In the days after the mega-telescope started delivering data, astronomers reported new discoveries about galaxies, stars, exoplanets and even Jupiter.

Hi #CoolStars21 👋🏼 If you’re interested in L dwarfs, come visit me at poster 76 today or tomorrow to learn about how uniform abundance retrievals can bias your retrieved mass and metallicity values! #cs21

Fun fact about this picture. @KVandorou and I were standing in front of @kerockcliffe @AstroMelRow and @DKrolikowski - before we had even met! Couldn’t guess we would become friends during the conference ☺️ #exo4
Dr. Dawn Gelino 💜⁷@DawnGelino7 May 2022
Thanks to everyone for an awesome #Exo4! I’m so glad that our hard work paid off! What if we threw a party and no one came? Luckily we didn’t need to find out. Hooray for the largest in-person exoplanet meeting ever! 😊 Travel home safely all!

Gunfire by British soldiers unfolded in Northern Ireland 50 years ago, taking over a dozen lives and later becoming known as Bloody Sunday. As Northern Ireland reflects on the grisly day, symbols of division and hostility still hold their power. nyti.ms/3u9RnZx
