Fast Radio Burst Real-Time Spectral Theory

General Discussion

Hello!

My Spectral Research on Fast Radio Bursts Repeaters

Fast Radio Burst (FRB 121102)

Used Casey Laws mp3. Of FRB 57643.mp3

what are FRBs?

more information on FRB121102 PDF download https://aas.org/files/resources/chatterjee-law-hessels-tendulkar-spolaor.pdf

My Research
I have done Many spectral analyzing of the 57643 File.

Settings used in Audacity app
Noise Reduction, Frequency smoothing, and Stretching the millisecond mp3. to 1 Hour duration
(Maximum bandwidth before stretch tones)

Programs Used
Audacity - Spectrum analyzer enabled

Noise Reduction Removal
Normalization
DC offset
Amplify
Paul Stretch
Frequency Smoothing - spreading the attenuation of “noise frequencies” across neighbouring Fast Fourier transform bins

Hardware used.

Phase Lock Loop:
The phase-locked loop (PLL) block is a feedback control system that automatically adjusts the phase of a locally generated signal to match the phase of an input signal. PLLs operate by producing an oscillator frequency to match the frequency of an input signal.

AM-Demodulation:
Amplitude demodulation is the reverse process of modulation
Notch Filter: A notch filter is a type of band-stop filter, which is a filter that attenuates frequencies within a specific range while passing all other frequencies unaltered. For a notch filter, this range of frequencies is very narrow.

Conclusion
The Phase Lock Loop and AM Demodulation Allowed for the Lightcurve of the FRB to be Expanded and Spectral (Luminosity) of Said FRB Object producing it.

Future Study followup
Need Faster Computer Capable of Rendering Larger resolution Spectral for Real Time Visual
graphics card used gtx 980m the 1 hour file is 163 MB and sometimes struggles to process the FRB sound file.

Zoomed In almost all the way of the 1Hour Long FRB produce incredible realtime spectral pulses of light (I recommend squinting the eyes it shows more intresting details)

digital oscilliscope of same audio showing more structural
Lissajous patterns

This part is the only object so far That I had found for sure that appears when the “object” speeds up Becomes Incredibly luminous at that point of acceleration seen in the other spectral video. As you can see it spins in a Yaw rotation quickly in a dynamic elongated and spinning

Im unsure if Its Natural signal or Artificial.
I do believe it may be a Neutron star
I hope to see something Distinct video showcase my work on this subject.
I believe I found something that seems to repeat and changes frequency and Flashing pulses of some unknown rotating spinning object.

I Will be posting more in the coming time. As I require additional hardware and programs, able to run digital oscilliscope and spectrals and other software at the same time to analyize in Real time to examine the progenitors closely. Will also Submit here Copy of the FRB file in-case anyone is intrested looking at it themselves

I firmly Believe if the Astronomers used a oscilloscope ( a test instrument that captures and displays the behavior of electrical signal over time) and Better spectral programs to identify signals. They would be able to quickly identify signals better and detect Microwave perytons quickly as well

Thank You For Your Time

Thank you for sharing your work. Im interested to hear feedback from the group.

Thanks for the info. Very interesting and educational. I don’t know a lot about these topics, but I am sure future members will.

Found Actual Pulsar audio files here: https://www.jb.man.ac.uk/research/pulsar/Education/Sounds/sounds.html

And Finding similarities with pulsar audio with my Fast radio burst audio

did some pulsar spectral

And found this intresting part in the FRB. This is the second time im seeing a small object moving quickly like this. (The object appears to be moving in a S shape pattern. It Goes Up and then Down and up again. the wavelength is also moving up and Down. The object moves in and out (Forward and Backward) like a Yo-yo movement, perhaps striking something with speed. When it approaches us closer the object appears bigger. But At this point it is also producing High Flux. Its possibly bursting light in sequences of 3) -possibly due to high flux scattering

I seen a short few seconds where I see a circular object closed in on whatever is pulsating like a yoyo

slowed it down, shows other animated effects

within the 1hr long audio data. the areas where there is low noise. These are where I am finding the good audio dynamics from to do the above FRB videos.. These areas produce very clean visible wavelengths… I have to try getting the rest of the audio that clean..

These are low flux regions the black areas.

This audio is something… requires technical experince to make
Oscilloscope visuals . I have no clue how to generate those kinds of cool animations.
So its rather surprising that im finding animations in a FRB..
