Paper day! I'm excited to share some results on how correlated stellar variability may affect future extreme precision radial velocity surveys. If you want to just read the paper, it's up on arXiv: arxiv.org/abs/2204.12512 Otherwise, here's a thread with some highlights...
Hey #coolstars22, here's a sneak peek at my poster that will be on display tomorrow through Friday! If you care about RVs or magnetic activity, let's chat! The poster number is super easy to remember: 123
Hats off to the #coolstars22 LOC for treating a large group of astronomers to a rocket launch during the opening reception
Congratulations to Postdocs Luhn & Martiniez from @uciphysastro who swept the 2024 UCI Postdoctoral Scholar Research Symposium: Jacob Luhn took 1st for oral presentation & Raquel Martinez 1st among posters! Both in exoplanet science. physics.uci.edu/node/14844
I took an image every minute during yesterday's eclipse to make this video. I don't have a tracker, so I had to align (rotate & shift) each frame by hand. It's out of focus in the beginning because of some high, thin clouds, but I'm happy with how it turned out! #Eclipse2024
ExSoCal 2023 was a success! Thank you so much to all who attended!
The eclipse as seen from Irvine, CA yesterday. Sporadic clouds in the first half made things difficult, so this is from maximum coverage (~9:20 local time) to the end (~10:50), with photos roughly 11 minutes apart. I love that you can make out some sun spots at the end!
It's a beautifully clear day and the greater LA area is getting treated to some impressive views of the snowy San Gabriel Mountains. Check out this interactive before and after I made as seen from @UCIrvine campus! public.flourish.studio/visualisation/…

My first earthquake (that I’ve been awake for). Got a pretty good jolt here in Irvine
A 4.2 magnitude earthquake occurred 9.94mi S of Malibu Beach, CA. Details: eqbot.com/6fW Map: eqbot.com/6fk
Awesome talk about the APF A-Star Retirement Program (AARP) by UCI postdoc @jacobkluhn !!
I’ll be sharing in public for the first time something I’ve been working on for the past ~3 years! Come check it out at 10:40am in Room 609:
UC Irvine chalk art meme champion! My surprised Pikachu was one of two winners the other day, but I’m pretty proud of how my Bernie Sanders turned out today #ucstrike
It was fun to help on this project! I love that the first night of NEID science observations were used for some cool stellar astrophysics with EPRV implications; there’s something really cool about seeing p-mode oscillations resolved in the time domain. Check out Arvind’s paper!
Really excited to finally share some cool results I've been working on! In this paper (arxiv.org/abs/2210.00544), we use @NEID_at_WIYN and @NASA_TESS data to look at how p-mode oscillations manifest as a source of correlated noise for precision RV measurements. Some highlights:
