Dr./Prof. Meredith MacGregor

Life has been chaotic recently, so I've been quiet here but it's big news time! I've accepted a new faculty position at @JohnsHopkins in the Department of Physics and Astronomy starting this fall. Really excited to dive back into the DC/Baltimore astro community!

@djulik Bluesky has really exploded this week!

Just for fun, I created a shortcut on my phone so I still have a blue bird icon that says twitter 🤓. But this platform has become really shitty. #astrotwitter seems to have moved between 🐘 and 🦋. I have both but I don't find the critical mass. What do you use most? #whereto

@jradavenport @ztfsurvey @alercebroker @NASA I think it can vary. ID8 is a pretty extreme system: arxiv.org/abs/1903.10627. This paper has a larger sample from WISE: iopscience.iop.org/article/10.384…

@jradavenport @ztfsurvey @alercebroker @NASA There's a class of extreme debris disks that show large speaks in IR emission and at least one also shows exocomet transits. Happy to chat more if you're interested! I've had an awesome undergrad digging around in TESS data for these sources...

@jradavenport @ztfsurvey @alercebroker @NASA Transiting exocomets?

Congratulations @astroxicana! So excited to have the chance to work with you at @JHUArtsSciences starting this fall!

My very first PhD student just passed her defense - Congrats Dr. Kiana Burton! 🎉 Feels pretty surreal to now have graduated my own student. Guess I'm a real professor now! 🙃

Save the Date! We’re hosting a community workshop May 5-7, 2025 at the @JHUBloombergCtr in Washington, DC to discuss the future of infrared astrophysics and synergies across the spectrum going into the next decadal survey.

Rescued this fluff ball exactly one year ago and now she is living her best doggo life ❤️

@cfroning @JHUAPL I went home after submission and promptly fell asleep on the couch...

@mmacgreg @JHUAPL I'm in a post-PMW haze, myself.

Hello world! The weather is beautiful here at @JHUAPL outside of the windowless conference room that has been my home for the last few days 🫠 Super proud of our FIRSST team for tackling the potential major weaknesses and getting everything submitted this morning!

And, congrats to all of the APEX team! This is not an easy process and you all deserve a restful weekend for surviving

@djulik @JHUArtsSciences Time sure flies!

@mmacgreg @JHUArtsSciences Wow, already! Congrats

And that’s a wrap on the semester! Taught my last class of ISM and Fluid Dynamics this morning, and now I can say that I’ve officially been at @JHUArtsSciences for a whole academic year! 🎉

@astronomills Amazing! Do you have a job posting? Or would you prefer students contact you directly?

Annual request to please respond with any post-bacc positions in astronomy you know of! Grad admissions was rough this year, and there are lots of awesome undergrads now looking for research positions to help prepare them to apply again.

@GregHerczeg I hadn’t heard this yet - What a terrible loss!

I was devastated last week to hear that my friend and colleague, Will Fischer, passed away. He was very sharp and also one of the gentlest people I've met. In a field of egos, he was unassuming and genuine. I will miss him. mariettatimes.com/obituaries/202…

@afeinstein20 Congratulations! That’s so exciting!

IT WAS CLEAR AND THAT WAS THE MOST AMAZING THING EVER!!!

Four Johns Hopkins experts held a virtual briefing on Friday to discuss the science of eclipses and what viewers should look for during the upcoming celestial event. Read the key takeaways at bit.ly/3U9HdVe.

Both dogs getting in on the eclipse action now!
