On the bird app, I play a game with my followers called #1vs2.
I show X-ray data of supermassive black hole from the Chandra X-ray telescope, and ask my followers if they think it's an image of a single point source or a dual point source (aka possible a pair of SMBHs)!
For the smallest separated SMBH pairs, it's not very easy to tell if the data is 1 or 2 !
What do you think? Is this a single or a dual? I'll send a sticker of a black hole cat to someone who guesses correctly!
@AdiFoord ok so I’d guess with that background it would be poorly fit as a single point source, so I’ll say either a double or an extended source - but maybe that’s a cheaty answer :) Very hard to tell the difference- depends I think (?) on the quadrupole moment, which needs really great SNR to measure, according to old deconvolution papers by Leon Lucy
@AdiFoord I really want to say single point-source, but I have absolutely nothing to back that up besides "vibe"
@AdiFoord with the assumption that you cannot see the center of a black hole, I presume there's just one in this case.
@AdiFoord that sticker is great and this topic is great so how can I not venture a guess! Double is my totally uneducated guess :)
@AdiFoord This is awesome :D Let's say ... coin flip... single source, definitely.
What is the source of the X ray? Accretion disk, or polar jets, or something else?
@AdiFoord is there some background information we can read? What does the color intensity map to? What's the size of a pixel? It sounds like a fun game.
@AdiFoord Cool! I'll guess dual. Does the color difference represent something having to do with magnitude?
@AdiFoord that's pretty fascinating. I study chart patterns for e.g. equities so it reminds me a bit of that. Does subjective pattern recall seem to help in these studies?
@noble you have a 50% chance of being right with a random guess 😊 but my Etsy store is: www.Etsy.com/shop/XtraGalacticStitches
Okay, here goes nuthin'. ... I'm so nervous ... let me catch my breath ... okay... um... .... .... 2?
@AdiFoord I have negative idea how to interpret the plot on the left, but can I ask where I can purchase a black hole kitty sticker??
