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! 🎯

arxiv.org/abs/2409.08090

Figure 1 of Garrison et al's paper announcing the Python package nifty-ls, showing that nifty-ls is significantly faster than Astropy's current method called fast.

Who uses #guix in any type of research related to #astronomy #astrophysics, please share your wishlist of missing software.

I am working on scheduled update 2024-03 for (gnu guix astronomy), most of it is #python #astropy #jwst related packages.

It would be nice to have yt-project.org/

> ... supports structured, variable-resolution meshes, unstructured meshes, and discrete or sampled data such as particles. ...

The package is ready and I might include it in the upcoming update.

I'm not paid to do that!!! This is the great title from Evelina Gabasova on how to have an impact outside our work.
3 pathways:
- scientific change: not only paper publications, community recognition; with a StarWars example: github.com/evelinag/StarWars-s her most impactful work started as a curiosity/fan project.
- Open source: much of #ResearchSoftware finishes as discarded toys. Using #FAIR principles to make them Composable. Like LEGO briks.
- open source move from toys to clubs (e.g. #astropy @turingway). Find collaborations, look at what's out there before starting from 0. Embrace slow software!

#Astropy 5.2 was released a few days ago. I contributed to a couple of new functions that allow to draw the beam and a physical scale on celestial maps. These should be useful if you use Astropy to plot #ALMA observations. #Python #OpenSource #Astrodon docs.astropy.org/en/stable/wha

Hello #fediverse! Time for an #introduction 🚀

poliastro is an #opensource (MIT) pure #Python library for interactive #Astrodynamics and #OrbitalMechanics. It provides a simple and intuitive API, it's fast thanks to #numba, and it handles physical quantities with units thanks to #Astropy.
