Low frequency variations of high frequency signals

I have been looking at the general situation of tracking and studying slow variations of fast signals.  If you have a star, its main signal is likely electromagnetic or gravitational.  You track its “colors” with an FFT or spectrometer, and perhaps its slow variations up to decades of years or longer. (“pulsar” OR “pulsars”) “MHz”

Notes about PixInsight on Houston Astonomical Society Facebook closed group

I have not used PixInsight, but read what they are doing at https://pixinsight.com/. The commercial license is 230 Euros (about $275). They have free versions, but not sure what limitations, if any. All their image processing workshops listed are from 2017. There are software tutorials by their “PTeam” members at https://pixinsight.com/tutorials/index.html I do not know how many

Gravitational, Magnetic and Electric Field Changes from Global Climate Change

I wrote yesterday about magnetism and gravity and temperature at gravimeter and related sensor array detector sites.  I give averages over all frequencies, but the fine details can be tracked across all frequencies from picoHertz to ZettaHertz. Relation between gravity, magnetism and temperature at the earths surface at /?p=1893 Today I realized that if global

Question for Houston Astronomical Society and anyone else on the Internet

https://www.facebook.com/groups/AstronomyHouston Can you suggest a program to take two images from different cameras, combine and compare them? I am too tired to write more programs. Just wanted to look at some pictures I found on the web and see how the fit together. They are the same part of the sky, but different rotations, different

Comment on my video Windows USB GPS Device Based on UBlox Chip and UCenter Software

Windows USB GPS Device Based on UBlox Chip and UCenter Software https://www.youtube.com/watch?v=uJZHVKGrl6Y @Ali Zitouna Hamed, I am not sure what you mean by “base ntrip”. I made this long ago and have not used UBlox lately. Since then i have been working on software defined radios, electromagnetic interference, gravitational wave detection, imaging arrays for gravitational

Comment on FIRST STUDY OF USING GRAVITATIONAL SIGNAL GENERATOR FOR THE MEASUREMENT OF THE GRAVITY SPEED

https://www.researchgate.net/publication/329838665_FIRST_STUDY_OF_USING_GRAVITATIONAL_SIGNAL_GENERATOR_FOR_THE_MEASUREMENT_OF_THE_GRAVITY_SPEED/comments The gravitational potential and the magnetic potential overlap. They are part of the same potential, but they have different spatial frequencies. In a simple picture they are made of particles of different sizes, mixed to make one potential field. The energy density of the gravitational fields is much larger than the corresponding magnetic field.

Note on all sky maps at radio frequencies – correlations, registration, collaboration

Richard, I was visiting http://sundog.stsci.edu/first/images.html looking for the current best radio map of the whole sky.  There are many groups making their own radio telescopes, and I thought it would be a good idea to register their intensities and coordinates against some reference.  Your page showed up “First”, but I don’t know enough about the

Note to a dark sky site about renting cameras with telescopes and all sky needs of the world

I picked this because your example was “start at $600 per year”. But I have no idea what this does. Throwing a bunch of jargon at me means nothing. That picture of the equipment looks like a jumble of wires and objects. Can you see all parts of the sky? Does it run continuously? How

Note in Houston Astronomical Society about Gravitational Engineering

https://www.facebook.com/groups/AstronomyHouston I have been looking at all the radio astronomy groups on the Internet. There are a lot of them, at all levels of age and experience and size. I am trying to see how many of the ground and orbiting networks are also picking up signals in the nanoHertz to GHz range. That includes

Comment on Pictor Open Source Radio Telescope – Recommendations

https://www.youtube.com/watch?v=70plmWJDt2k Open Source: https://github.com/0xCoto/PICTOR Website: https://www.pictortelescope.com/ Please leave the settings and all form fields. Don’t clear them. Just leave them the same as the last observation.  I am having to re-enter them ever time I make a request.  I am making series of requests.  Many people might.  Tell them how many files they will receive, how many
