GW151226 Intensive Tracking – standard binary or low volume compilation?

Now that we are getting GWs, we would like to understand better the systems that produce GWs. GWs have been found far from collisions with celestial bodies, such as black holes and neutron stars. Once we have discovered the GW, we use the “Bayesian Inference” to find the masses and spins of the objects that shot GW (to understand the concept, check out this video at 3blue1brown). Then we can use our weight loss and spin to answer: where are these corpses in Space? Are these conflicting themes packed into galaxies or separated from the atmosphere? But, it is difficult to answer such questions when our finances and spins are incorrect! So, in my recent research, I created a “deep tracking” tool to determine which crowds and spins best describe a given GW event.

I used this in-depth tracking tool to learn the “boxing-day” gravity wave, GW151226. The first work found that this GW was derived from a combination of two black holes (BHs) with ordinary masses and spins (case A). However, recent work has found that GW may have come from an unusual system: one BH can be much larger than another and have a faster spin (case B)

In these cases, the “deep tracking” approach involves piercing to determine which BH binary system best describes GW. First, we set down some of the found features of the black hole integration system, such as mass-ratio q (the minimum BH value divided by BH) and jeff (the active spin integration in the z-direction.). The pinnacle of original and new results is on the left side. We then applied the Bayesia considerations to these PINs. The output allows us to compare case A with case B. We find that both standard (case A) and unusual (case B) black hole pairs can define GW151226, giving the event a dual identity!

This dual identity gives GW151226 a much more prominent character than previously thought. For example, we initially believed that GW151226 came from a different black hole pair. However, a couple of BH from case B will probably be found in the center of the active galaxy! So, finally, I wonder: are there other GW events with different personalities? Hopefully, our in-depth tracking system will be able to answer these questions.
