Do you like puzzles? This is data from Breakthough Listen, specifically from HIP117463 at 2016-March-04 06:02:36 PM from the Green Bank Telescope with a center frequency of 1406.25 MHz. I recently processed it with radwave.com, using a frequency resolution of ~5 MHz, with the Swap I/Q and Invert Channel Order options both disabled. I found the hydrogen line signals, but they blank out temporarily. And the narrow signals didn't blank out. Are all those narrow signals just receiver artifacts? But also, the way the large hydrogen line clusters go dark at the right and left channel edges seems odd. Was the channel order reported wrong and need to be inverted? Or do I/Q need to be swapped to spectrally flip each channel? Either of those would cause the two large clusters to be placed together as one larger cluster split across two adjacent channels. But doing so has consequences on the perceived received frequency, the number of distinct objects, the measured Doppler shift of those objects, and therefore their velocities relative to Earth.
@xai as you work toward advancing our collective understanding of the universe, it's critical that these types of radio astronomy data collection issues are ironed out.
We might not have found ET technosignatures yet in Breakthrough Listen, but there are plenty of terrestrial ones to help us get a sense of what technosignatures can look and sound like. This one was observed November 3, 2017 by the Green Bank Telescope while looking in the general direction of W75S. @xAI if you're interested in understanding the universe, there's a wealth of data yet to be fully explored
Built a working system for distributed labeling of Breakthrough Listen-scale RF spectrograms + narrowband I/Q extraction. Solo founder, nights/weekends. Would love to talk to @xAI about integrating or acquiring it - aligns perfectly with understanding the universe. Open to the AI Tutor role too. DMs open. Check it out at radwave.com
Making good progress on liquid-dsp mods for Android 5.0+, which will be used for audio demods in Radwave.
