Numerical Fourieri Analysis of a GRB light curve

AI Thread Summary
The discussion focuses on analyzing gamma-ray burst (GRB) light curves using numerical Fourier transforms on count rate data recorded every 64 ms. The original poster seeks guidance on applying a discrete Fourier transform to their finite dataset, as most available resources discuss Fourier transforms in terms of integrals and continuous functions. A user named Laura expresses interest in collaborating and offers to provide assistance after receiving more information. The conversation highlights the need for practical methods to analyze GRB data effectively. Collaboration and sharing expertise are emphasized as potential solutions to the challenges presented.

Hey everyone,
Ok, my ultimate aim is analysis of gamma ray burst light curves, so i have data which includes count rate in a certain energy range recorded every 64 ms. I would like to apply some kind of discrete, numerical Fourier transform to this long list of data, in order to produce a new graph that tells me something about frequencies present. I'm not at all sure how to go about doing this for a finite list of numbers, since all info i can find on Fourier transforms is in terms of integrals and functions...any help at all would be greatly appreciated!

Hi Valkyrie,

Send me a private message. What you described is roughly what I do in my research. I need more information before I can help you out. Perhaps we can collaborate.

Best wishes,
Laura
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
