I'm excited to announce my newest paper out on arxiv: Expanding the High-z Supernova Frontier with JWST 🚀 We just used JWST to push transient astronomy to z ~ 5, discovering 68 supernovae...all without a dedicated time-domain survey. Here’s what we found 👇🧵 1/n

It's been an exciting 2025. I haven't done a great job promoting my work on social media, so over the next couple weeks, I'll make an attempt to summarize three of my biggest papers. Stay tuned...we'll see if I actually get this done.

Roman Time Domain Session at 10am! #AAS247

As I have the past 3 years, I am organizing the a “Foodie Dinner” on Wednesday night, January 7th at 7pm. Location will be sent to those who sign up. At the current time, I have 3 spots left. PM if interested. #AAS247

🚀The Roman Cycle 1 Call for Proposals is OPEN! Unlock new discoveries with the Wide Field Instrument—your science starts here! Apply for funding to analyze Roman data, perform theory/lab research, and propose new observations. 🔭☄️ 📅 Deadline: Mar 17, 2026 (5 PM PDT) 📝 bit.ly/4q3jbbL

Got a look at @nasaromantelescope.bsky.social this morning. And it was looking right back.

🚀The Roman Coronagraph Community Participation Program (CPP) is meeting this week at IPAC in Pasadena, CA! The team is gearing up for commissioning, observations with the Coronagraph, and preparing for the launch of Roman next year. Exciting times ahead! ✨🪐 www.romancoronagraph.space

I don't post a lot, but I am particularly proud of this paper. It's the first observational sample of binary companions to stripped envelope supernovae. And places constraints on the binary evolution physics. It only took me 10 years to build with HST! arxiv.org/abs/2508.12677

In these turbulent times for science, I can't resist putting out my "Case For Space". It's sometimes a little scary to speak up, but here I go. I hope this doesn't go viral. 😉

🚨Get Ready for #AAS246!🚨 Follow us daily for your dose of #NASARoman at AAS: talks, posters, booths, sessions (and stickers) —we’ve got it all. 🔭📡📸

🚀Want to get involved with #NASARoman before it launches? You can tune-in, interact, or actively contribute. It's a great way to gear up for the Cycle 1 Call for Proposals coming in late 2025! 👩‍🚀🛰️ Find out more: bit.ly/4kigJM9 #ExpandOurView

Let's get back to Euclid's Early Release Observation (ERO)! 🔭 This is a new version of mine of the Messier 78 observation by Euclid. I wanted to improve my first try from months ago, so here is it! M78 is a nebula located some 1,350 light years away. HD: flic.kr/p/2r6juDX

Join us for "Cosmic Cartography with Roman", a symposium on how our large survey maps will be used to explore the intersection of dark energy and dark matter, including galaxy formation/evolution. @stsci.edu - July 14-18! Speaker schedule now available. Register by June 9. #CCR25 bit.ly/4jYe3TH

Representing @nancyromansci.bsky.social at the Congressional @planetarysociety.bsky.social Caucus event with Bill Nye and @stsci.edu! www.planetary.org/advocacy/the...

If you're looking to get involved in #NASARoman, *now is the time.* Cycle 1 Call for Proposals will be in Fall 2025. This workshop at #AAS246 is one of the best opportunities to get involved and early access to the cloud infrastructure. #LongLiveRoman

Next #NASARoman Virtual Lecture on May 15! "Chromatic Effects on the PSF and Shear Measurement for the Roman Space Telescope" - Federico Berlfein (Carnegie Mellon) For more information, visit roman.ipac.caltech.edu/Lectures.html #ExpandOurView

🚀We are ready for launch...of the official social media account for doing science with #NASARoman! This account will keep researchers informed about opportunities for preparing for and participating in Roman science. Follow us to stay involved. #ExpandOurView

Excited to announce the 'Rutgers Summer Transient Soiree' this July 16-18! To offset the uncertain funding landscape, we are offering a hybrid option + requiring NO registration fee. Non-faculty are especially encouraged to apply! Please apply by May 31! More in the replies! 🧪🔭☄️ #highenergyastro

Just 3/4 of it! I’m hoping the other fourth will include an ultra-deep field 🤩

You probably know the Pillars of Creation in Messier 16, let me introduce you to other pillars in our own galactic center! 🔭 Named the Sickle, these are pillars seen by the JWST in mid-infrared in the center of the Milky Way. The stars being born here will be monsters! HD: flic.kr/p/2qZFSpD

The Nancy Grace Roman Space Telescope observing program is going to be amazing. Can't wait. #NASARoman @nasaromantelescope.bsky.social www.nasa.gov/missions/rom...

Very proud to see @NASARoman ROTAC report on initial 5-year mission plan come out today...and have my name on it! This is the FUTURE of astronomy. #Roman #LongLiveRoman t.co/Co9qgBrKr6

In case you missed it…. Special Announcement: Recommendations for the Roman Core Community Surveys to be Announced Thursday, April 24 at 12pm EDT. Details below. outerspace.stsci.edu/pages/viewpa...

Maryland voters: join me on the @aas.org Zoom on Friday at noon. I'll give a short summary of the congressional appropriations process, and I'll walk you through making your own request for funding for NASA, NSF, and DOE Office of Science. 🧪🔭 Zoom at noon on Friday, April 18: bit.ly/3Y1cJq2

Here’s how I know AI still has a ways to go. The automated voice conversation on United Airlines couldn’t make it past the first question where my answer was “No.”

Abstract Deadline Reminder: "Cosmic Cartography with Roman" will be this year's official @NASARoman summer conference, focusing on the advances in Galaxy Structures, Distributions, Dark Matter, and Dark Energy. Abstracts due next Friday, March 28. www.stsci.edu/contents/eve....

Registration is now open for the next JWebbinar – NIRCam and MIRI Coronagraphy: An Update 3 Years into #JWST Operations – to be held on April 3rd. Get the details: ow.ly/ewNq50VgoQW

OMG. Last night's lunar eclipse -- as seen from the Moon! The Blue Ghost lander got this shot. The Sun is overexposed, but in the reflection you can see it's almost fully eclipsed by the Earth. 🧪🔭 fireflyspace.com/news/blue-gh...

Transients From Space 2025 group photo! #TFS25

Incredible night for #TFS25 where Karrie Gilbert gives a @astroontapdc.bsky.social at Guilford Hall Brewery.

Yvette Cendes: Ignore radio at your own peril. #TFS25

Masterson: Incredible Mid-IR spectra of TDEs with JWST! The WISE-selected TDEs sit up with the AGN host-galaxy line strengths. #TFS25

Megan Masterson: TDEs prefer post-starburst host galaxies. #TFS25

Christos Panagiotou: Deep IR surveys from WISE discovered the closest TDE ever! #TFS25

Yuhan Yao: Highly Variable X-Ray emission detected with Swift tells us this can't be a SN, but must be an offset TDE from a wandering black hole. #TFS25

Anya Nugent: Host galaxies are key to distinguishing transient types and identifying their progenitors. #TFS25

Fed Bianco: AI is used in every stage of survey science! #TFS25

Kishalay De: IR Surveys stand to make a big impact in all astrophysics (BOOM!). #TFS25

Haojing Yan: PEARLS is finding great transients, too. North Ecliptic Pole the best place because of the CVZ. #TFS25

Wenlei Chen: Lensing measurements of SNe Ia can potentially put some important constraints on the Hubble tension, although the small sample and large error bars are not too constraining...yet. #TFS25

Justin Pierel: High-z SNe Ia are WEIRD! Look at that red color of SN2023adsy at z=2.90! #TFS25

Christa DeCoursey: Supernovae Supernovae everywhere you point with JWST. 1-2 SNe per square arcmin down to 30th mag. #TFS25

Hey, so while I totally appreciate everyone's good work selling Tesla stock and offloading their Tesla vehicles, something that is MUCH quicker and cheaper and is relevant to MANY MORE PEOPLE would be to GET OFF TWITTER.
