Nice to see Kepler/K2 and TESS leaving their marks on MAST!

A patch of young New Zealand native trees on a grassy hillside.

700 new native trees in the ground from today's Trees for Canterbury planting at Orton Bradley Park. Another small patch of Aotearoa returning to what it was.

An urn containing the ashes of each PhD thesis from the Research School of Astronomy and Astrophysics

It's always nice to check in on my thesis when visiting Mt Stromlo 🔥

Fantastic presentation on Timescape by @ryanridden.bsky.social yesterday at the South Island Stardate. Exciting times in cosmology! He also gave an awesome presentation on Cosmic Cataclysms and how we can get involved in it through zooniverse. Wow! Some great research going on at UC!

A series of TESS lightcurves extracted by TESSELLATE which include example events of GRB afterglow, dwarf nova, flare star, variable star, asteroid detections, and an exoplanet candidate.

In analysing just a few sectors we already have an extraordinary number of objects to study across all areas of astronomy! If you like grb afterglows, stellar flares, dwarf novae, variable stars, asteroids, and even exoplanets, then we've got lightcurves for you!

TESSELLATE: Piecing Together the Variable Sky With TESS We present TESSELLATE, a dedicated pipeline for performing an untargeted search documenting all variable phenomena captured by the TESS space telescope. Building on the TESSreduce difference imaging p...

New paper up on arXiv! We present the TESSELLATE pipeline to conduct a general transient search of all TESS data. This is a massive goal that I've been working towards for years which was made possible by my incredible students and co-authors!

We have more data going up now! Keep an eye out for a comet that is photobombing TESS ☄️

I'm amazed at how fast the citizen scientists tore through the dataset. It's made something that seemed like a insurmountable task suddenly feel very achievable!

Just a few hours in and a lot of cool discoveries already!

Here's a newly observed outburst from the cataclysmic variable ASASSN -14je.
