Heavy lifting is done by #astropy and #sqlite. Might work on a rust version of this in the future, which actually motivated the come up!

Astro update 2025/04 is on the way to be submitted.

Checking for full stack success build, so far no major issues with #Astropy 7.0

#Guix #Astro

Me, trying to refresh #Astropy to 7.0+ in #Guix which needs #Python 3.11 and #NumPy 2.0+
[PATCH 00/34] Astro update 2025/03.

Building #Python tools for astronomical data analysis?

#EuroSciPy2025 is seeking proposals on cosmic modeling, observatory data pipelines, or celestial mechanics.

Help us reach for the stars!

[PATCH 00/38] Astro update 2024/12

Good news everyone!

October Astro soft update is out there for review in Guix.

This month brought us the latest @astropy, Stellarium and @Siril_Official.

IRAF Community, maintained
by @olebole, is packed and will be available after it's reviewed and merged.

[PATCH 00/42] Astronomy update 2024/10

I have a completely crazy idea!

To rewrite #astropy in #swift!

How many GWh electric energy would be save if astronomers do adopt it?

Well, I already started it a while ago. Working on geometric and time conversions AtM. Of course it will be open source.

Whoa.

`nifty-ls` claims to be a faster, more accurate drop-in replacement for #astropy's Lomb-Scargle periodogram.

I've briefly experimented with the Kepler short cadence light curve for the enigmatic δ Sct variable HD 187547 (~1M data points) and `nifty-ls` really is ~5-8× faster than the usual `fast` method, for the price of one minimal-dependency import and one keyword argument. 🚀

Plus the authors show it's more accurate, too! 🎯

nifty-ls: Fast and Accurate Lomb-Scargle Periodograms Using a Non-Uniform FFT

We present nifty-ls, a software package for fast and accurate evaluation of the Lomb-Scargle periodogram. nifty-ls leverages the fact that Lomb-Scargle can be computed using a non-uniform FFT (NUFFT), which we evaluate with the Flatiron Institute NUFFT package (finufft). This approach achieves a many-fold speedup over the Press & Rybicki (1989) method as implemented in Astropy and is simultaneously many orders of magnitude more accurate. nifty-ls also supports fast evaluation on GPUs via CUDA and integrates with the Astropy Lomb-Scargle interface. nifty-ls is publicly available as open-source software.
