I think he refers to her at his Fuhi which (in gujarati) is part of a whole vocabulary of extended family relations that doesn't translate well and gets compressed into aunt/uncle

I'm still confused by the cousin-x-removed in English tbh

Just after sunset to the west! The star Alphecca (alpha CrB) is in this photo, so it's quite close to the constellation corona borealis

Forgot the astrophoto tag!

I took this w a monochrome camera & refractor w H-alpha etalon (Daystar Quark). 800 frames every 30s, best 5% stacked. Autostakkert, ImPPG for alignment, Wavesharp for sharpening and final warp stabilizer in Premiere. Humans have poor acuity in the real deep red H-alpha so colored orange instead.

In a companion paper, PhD student @maxecharles.bsky.social applies this to reconstructing complex images, not just fields of dots. We apply a regularised maximum likelihood method to restore clean, diffraction limited imaging by fitting directly to pixel level data.

In the first paper Louis Desdoigts (ex PhD in my group, now Leiden postdoc) learns a model for the entire AMI system's optical physics together with a neural network 'effective detector model' the sensor, which suffers from a serious 'brighter-fatter effect' that blurs images at the pixel level.

Yeah, it was labor intensive for sure. 15 mins for each video plus >100gb, but I'm a grad student so I've got time 😆

It's all hand-tracked! I aligned the long axis of the camera in the direction of the drift and would recenter it every few seconds.

Research also shows that spreading smaller amounts of funding out over more researchers generally delivers better scientific outcomes per dollar spent than focusing bigger grants on fewer researchers.

FFTs are pretty hard to beat in speed but restricting to the surface of a sphere and the analytic solution certainly helps! The goal is to do HMC on the surface map coefficients

I believe @astromonnier.bsky.social has work on interferometrically detecting hot Jupiters from closure phases, maybe he'd have more to add about this
