... showing multiple galaxy maps conveys different properties - but we can't watch them all at once... I'm interested in sound to enhance perception of data, and find new things! If you have application ideas, try our STRAUSS sonification code (github.com/james-trayfo...), or let me know! 🧪🔭⚡🐡

...Temperature illustrates the hot outflowing gas corresponding to the windy sound - pale plumes emanate from the central region. Sonification allows us to represent this with sound while visualising something else - such as starlight - so we can impart more dimensions of the data at once! 🧪🔭⚡🐡

The sophisticated COLIBRE simulations finally land on the arXiv: arxiv.org/abs/2508.21126. Treating these with sonification, we can get new intuition for galaxy evolution to augment our visuals. Sound on for the explainer vid, visit the site for more! colibre.strw.leidenuniv.nl/videos.html 🔭🧪

Next paper I want to highlight: the paper for STRAUSS by @trayford.bsky.social et al. came out! ☄️ #astrocode STRAUSS is a tool for sonifying scientific data, meaning you can enhance the presentation & accessibility of your data. Paper: arxiv.org/abs/2504.01660 Here's a great example:

Through diverse perspectives, we discover a lot. We found composite rhythms in calypso ideal for representing many planets at once, which we will build on. Arron guided us musically, providing the joyful incidental music, instrument recordings and endless enthusiasm...(3/n)🧪🔭🐡 #edusky #musiciansky

Collaboration helped us do this as authentically as possible; The instruments chosen to 'voice' each star and planet, the harmonies used that represent calypso styles, and the relative emphasis on musical elements like melody, rhythm and harmony... www.port.ac.uk/news-events-... (2/n) 🧪🔭☀️🐡 #EduSky

This has happened to me before when i'd forgotten to convert argvals from strings. My favourite recent is converting a numpy boolean index array to an integer array by accident so it just happily indexes the 0th and 1st element and yields garbage

I've definitely seen instances of people new to creative mediums referring to things they've generated with prompts as 'my art'. I think what they're closer to is curators, and that curatorial skill is usually developed alongside the creative one (choosing ideas, throwing away bad ones)

A nuanced issue fs, but definitely one worth bringing to light!

James Trayford @trayford.bsky.social · 15/12/2024
A potential issue I see, though, is further encouraging a wide-shallow mode of applications, which makes more work for everyone and I think is more likely to lead to a mismatch between people and positions (e.g. 'a' and 'b' ending up in each others ideal positions...)

I think randomisation is the only way to fully remove bias - though ofc must be mindful that this can cut both ways.

Progress! Star lives with sonification 🌟🔉. Models colour evolution from 0.3-150 sun masses. A higher note indicates higher main sequence temperature, shifting with post-MS temperature pre-death. They go 'bang' if they then go supernova or 'whoosh' if they blow out to leave a white dwarf. 🌌🔭🧪💽🐡...

...the point being that we need to be careful what we _mpose on data by sonifying it. Musical elements can have a strong emotional asssociations. Are satellites good, bad or neutral? The choices we make can communicate different things. Understanding these things can help with visuals too 🔭...
