So if I got it right... this isn't an upscaled AI image, but what's happening here instead is the original EHT image was totally theory agnostic in order to avoid bias, and now that we know that it is in fact a black hole ring shaped by general relativity PRIMO can apply known physics to the original data to resolve the image in accordance with known theory... I think? Thanks as always for the great videos!

3:35 why would a doppler shift increase the brightness? Wouldn't that decrease the wavelength?

@ytrrs Год назад

Good question. My guess is: the increased doppler shift frequency from the region of the accretion disc moving towards us, results in more energy incident on the antenna than the region that moves away from us ( since E = hf ).

@100vg Год назад

It seems odd that the brighter ring areas don't match the same positions as the original EHT 2019 composition. The bright area on the left at ~255° is gone and the lower mid-left is brighter with a dim space where it was brightest. It seems odd for the same data to present such different results. OK, it's rotating. Will Webb be imaging this black hole? And why should a black hole look like it's wearing a hat from some angles? The 90° bend is anti-intuitive. Thanks. It's been a while. I hope you've been well.

@charleslivingston2256 Год назад

It is not technically correct to say that each component antenna combined to form the image is seeing a different part of the image. Each of the individual antennas see the whole image, just at poor resolution. Effectively, each antenna has the "whole image" within a single pixel. As you add together that single pixel of different, separated antennas, you make the resolution of the resultant pixel much finer. By changing the relative phase before adding them up, you shift the location of that finer, resultant pixel (constructive interference occurs for a different pointing angle). Doing a lot of different phase adjustments you to form a lot of different pixels of the final image. The problem is, if two antennas are spaced more than half a wavelength apart, then there are multiple direction with that peak gain. The farther separated they are, the more different directions have that same gain (called grating lobes in passed array radars). Adding more antennas to combine reduces the number of grating lobes (and increases sensitivity)

@charleslivingston2256 Год назад

When adding up different antennas using interferometry, you are working with the phase at each antenna. If the phase difference is 10°, you don't know if it is 10, 370, 730, ... degrees. This means when you are adding up the sources with phase adjustments so the as up constructively in the desired pointing angle, they also add up constructively in other directions (called grating lobes in passed array radars). What you get is not just what is at the pointing angle, but the sum of that and all those grating lobes (plus other stuff, just at lower gains). The more wavelengths apart your individual antennas are, the more grating lobes you have to contend with. There is guesswork in combining a sparse interferometer whether it is the scientists doing it or an AI.

(1) The radio waves that we can't see, gives the data; (2) the visual image is a radio image that we can't see; (3) EHT synthesizes an effective antenna aperture of Earth's size; A.I learns about 30K simulated models of black holes and refines the image! I'm more and more convinced that REALITY is not absolute and is in the eyes of the beholder.

@JenniferA886 Год назад

Imagine if there was a telescope on the moon? 👍👍👍

@charleslivingston2256 Год назад

Yeah, but most discussions of radio telescopes on the Moon talk about being on the far side. That decreases how much that improves the interferometric baseline. That being said, it would still be a big improvement if the Moon data is collected from much of an angle. The resolution of the Moon data decreases with increased scanning angle (off of perpendicular to the antenna), proportional to cosine of the scanning angle. However the Moon array can be quite large, so resolution is still good. The interferometric baseline has a factor of sine of the scanning angle, but it is the multiplied by the distance to the Moon. Since the distance to the Moon is almost 30 times the Earth diameter, that adds a lot. The problem is, the larger the gaps in the interferometric baseline, the more grating lobes there are. This means other directions with just as much gain as the desired pointing direction.

Q ???

@dat_21 Год назад

Just the fact that the data allows so many different interpretations doesn't make it very trustworthy. Maybe there wasn't any black hole to begin with and it's all in the interpretation. I mean if they somehow add many more sampling points and improve their SNR to the point where there will be no room for interpretation, it will be a "picture" of a black hole. But so far the data is very unreliable at best.

Why are the two "images" so different (i.e. where the brightest areas are)? It's hard to have faith in either of them because of that.

It’s partly because the PRIMO version wasn’t required to be model agnostic, but also because there is still work being done to assess the physical properties of the image.

@JCO2002 Год назад

@@LaunchPadAstronomy Thanks. So the PRIMO version used an assumed model to construct the image? You can basically come up with anything you want doing that.

That's why the first images were done by teams that were separate so each was agnostic. Once they had an image they were able to refine things. It's not pseudo science.
