Everyone go check out Ryan's paper on one of the coolest star systems in the galaxy (not biased) Also I was glad to contribute to this work in an artistic and scientific scope by creating this false color composite image! 🔭🧪

Here's I3/ATLAS from the 0.8m at Mt Kent as of 1 hr ago. The clip is a 50-min sequence.

UniSQ PhD student Emma Nabbie has a cool paper about a Kepler system showing more than 24 hr of TTVs! They show that the system can be explained by a mutually inclined (15deg) non transiting interior planet at 2:1 resonance! See paper! www.nature.com/articles/s41...

Phil Armitage, Dan Tamayo @astrodan.bsky.social, and I will host a workshop April 22-25 at CCA @flatironinstitute.org in New York on methods and applications of ML for planetary dynamics and exoplanet population inference. Express your interest in attending by 3/3/25: forms.gle/zgzkUDCs8Uzz...

I'm looking for a two year postdoc to work with me at Macquarie University building an Astrostatistics Research Group! We're interested in diverse applicants with previous experience in applying stats/AI/ML in astronomy, especially in relation to exoplanets/stellar astrophysics/instrumentation.

The tail of comet G3 is extraordinary! It was already visually stunning to me in dark skies, but in photographs there is so much detail in its striations and bands - the poor comet has been stripped apart. Taken over farmland in southern Queensland as thunderstorms rolled by. 50mm f2.2 36x10s 800D

Go work with Ben at Macquarie! A great opportunity to join one of the best research groups in Aus, and be part of the growing exoplanet community here!

PhD positions in exoplanets: - with @georgezhouastro.bsky.social at the University of Southern Queensland bsky.app/profile/geor... - with me at Macquarie in Sydney bsky.app/profile/frin... Others - reply in thread?

Come join the exoplanets team at UniSQ in Australia. Our team is seeking multiple PhD positions to understand the formation and evolution of planetary systems, involving ongoing programs on JWST, HST, and VLT. See AAS advert. Applications before March 07. aas.org/jobregister/...

Comet G3 is getting exciting! Here it is from my back porch overlooking Toowoomba just an hour after sunset. 110mm 26x4s

I love comets - there are very few things visible to the naked eye that come and go in the night sky. Comet G3 low in the horizon soon after sunset, only 11deg from the sun. Hoping it will remain bright for a week or more.

My new paper is out today on searching for stellar companions with pulsation timing in TESS photometry! arxiv.org/abs/2410.19729 Paper thread below ⬇️

Venus, Comet A3 (Tsuchinshan-ATLAS), the Milky Way, and Zodiacal light (if you can spot it) all in one shot! Taken at Mount Kent observatory 🪐🔭

Comet Tsuchinshan Atlas has been quite a show over the last month. Some final shots before it fades away from us. One of the best comets I’ve see for a long time.

We were joined by a special guest while setting up for comet photos. Joys of Queensland

From 27deg S, our part of Queensland is not well know for its Aurora displays

My first PhD paper is on arxiv today! Rotating planets are slightly wider at their equator compared to the poles. Saturn in our Solar System (below, minus the rings), is about 10% oblate! Can we detect this shape difference in transits from JWST? (1/N) arxiv.org/abs/2410.03449

The tail of Comet Tsuchinshan-Atlas stretching dozen degrees, amazing in dark skies :) With @astroshishir.bsky.social

The long tail of Comet Tsuchinshan-Atlas stretched over Toowoomba 70mm

Tsuchinshan-ATLAS growing a nice tail now. Still difficult to see without binoculars, so low to the horizon before sunrise.

Getting up at 4am to see Comet Tsuchinshan-ATLAS rising over the Toowoomba range

To kick off the group, we're recruiting a 2-year postdoc and have an international open PhD scholarship, plus domestic PhD students. We're looking for people with strong experience & interest in stats, especially connecting differentiable physics models, HMC, GPs, NNs, and SVI.

Excited about @sydneyvach.bsky.social 's discovery of a 60 million year old planet system in the Theia 116 association. arxiv.org/pdf/2407.19680

🚨🚨🚨 IT’S DONE! ❗️The ARC Review Response Bill just passed parliament❗️ No more political interference in individual ARC grants! The ARC will get a Board, who will approve individual grants. It’s a wonderful day for Australian research!

My first PhD paper on "The occurrence of small, short-period planets younger than 200 Myr with TESS" has been accepted to AJ and is now available on arXiv! I'll also be presenting a poster on the paper at #ExSSV (607.02)! arxiv.org/abs/2403.03261

Highlighting new paper by UniSQ PhD student Sydney Vach! She computed the occurrence rate of planets <200 Myr with TESS. arxiv.org/abs/2403.03261

Hello from Toowoomba, Queensland! When I’m not pretending to put AO on our local telescopes with laser pointers for photoops, I’m enjoying the company of two fur babies and one skin baby.
