Hello wonderful people on #Steemit! A very warm greetings to one and all present here. Hope you all are doing well in your life! In today's article, we're going to be discussing about going to the middle or the center of our galaxy and discuss about a recent study which basically suggested that we finally discovered the various types of black holes very close to the actual center of the Milky Way Galaxy.
Hope you people will read my article and provide your valuable suggestions and thoughts by commenting below. So, without any further delay let us start the exploration!!
This new study actually is based on the theory that suggests that right next to the central black hole; basically [Sagittarius A]* within about six to may be ten light years there should be a tremendous amount of black holes. Specifically, close to about 10000 black holes. So, let's actually first go to the [Sagittarius A]* which is right in the center of this very large globular cluster and there if I go to a distance of about ten light-years within this distance; there should be a tremendous amount of black holes. Now, for the longest time we couldn't really find any. As a matter of fact, as of today there's only about may be 60 or so black holes were discovered in the entire galaxy and that's not really even close to the theory and this so-called density cusp as it's known has been basically nothing but a theory.
Now, in Space Engine if I was to come closer to the central black hole and to then search for any kind of black holes within 20 light-years away from us or even more than 20 light-years; I can actually even put 50 light-years. I will unfortunately find nothing. So, even this is currently set to basically only detect black holes with a much lower frequency. But the reality is that most Scientists or most Astrophysicists believe that there are tremendous variety of black holes within about one parsec away from [Sagittarius A]. In other words within about four light-years of the central black hole there should be close to about 20,000 of these beautiful objects.
Now, where exactly are they? Well! It turns out and this is coming from a very recent paper by Charles J Haley, Kaya More and Franz E. Bauer and a few other people. This was actually posted in Nature magazine very recently in April of 2018 turns out that they actually use previous data from the Chandra telescope and what they did was look at the binary. Specifically, the so called x-ray binaries similar to the Cygnus binary. Basically, these are binaries containing a black hole and another object and normally these can be a relatively energetic. But they were looking at just the regular binaries that may actually have black holes that would have an accretion disk and these accretion disks in binaries will actually produce a little bit of x-rays and so they actually just looked at these more or less not so energetic black hole binaries and what they discovered was basically at least a dozen of these objects within about one parsec of the central black hole. They actually even took a photo of it which you can see just above and so there you can find [Sagitarius A]* and you can see every red spots that you see in that image is basically an x-ray coming from most likely a binary black hole.
In other words, they were able to discover quite a lot of these unusual binaries in this region that we haven't really seen before and using statistics we can actually estimate that there's probably a lot more singular black holes out there. So, even though they want to discover about a dozen or so binary black holes. Just based on the understanding of how black holes form and how binary systems work we think that there is probably something like at 10,000 or possibly 20,000 singular black holes hiding out there very close to [Sagittarius A].
Now, this is within a distance of about four or so light-years. So that's actually not very close and if you want you can simply see in Universe Sandbox so that you can get an idea of how far away it actually is in terms of distances and in the Universe Sandbox if we place [Sagittarius A] right in the middle we have place may be a few smaller black holes at a distance several light-years and that actually pretty far away. So, there's probably about 30-40 black holes we will discover now and these were all binary black holes. But at a relatively large distance and it's actually somewhat similar to distance between our Sun and the closest star to us which is Proxima Centauri and Proxima B is the planet around that star.
So, it's not that close. But like I said within this distance they expect at least 20,000 black holes which is actually quite a lot. So, even though there are actually also stars here but there is actually a tremendous amount of these Black holes as well and this is what we refer to as the density cusp. Mostly, because we believe that lot of these black holes came here from the outer edges of the inner galaxy and they actually ended up closer and closer to [Sagittarius A]* and a lot of them actually do end up following to [Sagittarius A]* . Thus increasing its mass! At least that's the theory behind it.
But because these are black holes; we won't really see them because they don't really emit any light and if they're not in a binary system they don't even have any accretion disk to basically provide any other energy either. They would only be emitting light if and only if something actually falls into them. Well! That's all I wanted to discuss in this article and now we know that the unusual region around [Sagittarius A]* actually possesses quite a lot of invisible black holes that we don't really see. In other words, even though this was a theory until now. We have now been able to detect at least a dozen unusual binary systems which are quite rare usually where there is or at least might be some sort of a black hole that is emitting x-ray radiation. There is really no better explanation for what it will be and so that's all I wanted to share with you all in this post and hopefully you have learnt something from it.
