The two slides below show velocity and mass distribution of Milky Way from LRO data 30/12/2023. Andy
Radio observation in hydrogen line (1420MHz)
Measuring data at 102.1 degrees elevation with Ptarmigan Array (Milky Way Hydrogen Map)
It appears my map with the extra 96.6 degrees elevation readings is now close to maximum I can achieve (see plot on previous post). I am going to try adding…
Results of adding 96.6 degrees elevation (beyond Zeinith by 6.6 degrees) to my galactic hydrogen map
Adding bricks to point the Ptarmigan Array beyond the Zenith 21/12/2023
Today I decided to find out what happens when I take the array to point other side of Zenith (ie > 90 degrees). Will it just give same data as…
Latest hydrogen radio map (1420MHz) Milky Way from LRO 20/12/23

First light on additive interferometer
Experiencing difficulties with my multiplying interferometer (which means it doesn’t work yet!), I am trying a simpler additive interferometer using 2 x Nooelec 1.4GHz dishes, SAWBird+ H1M LNAs at dishes,…
Determining the galactic rotation curve of the Milky successfully with my 1420MHz array
Galactic rotation curve from my data: Below shows exercise of picking points for curve above in my data: Compare my rotation curve above with typical Keplarian rotation curve (not from…
Interferometer test rig
My proposed test rig for interferometer, although I intend to change the splitter to power splitter. Andy
