Astronomers record signal coming from deep space every 157 days

What could happen powerful radio signal, what repeats simultaneously in 157 days periods? (1) If the signal comes from our galaxy, theories like falling neutron stars or white dwarfs. In those cases, the material would mass on the surface of that object and cause the eruption. So what makes this radio signal interesting? 

It is FRB (Fast Radio Burst)(2) not GRB (Gamma Ray Burst)(3) or X-ray burster(4), which is normally the sing of the black holes. The sender of FRB (Fast Radio Burst) is predicted to be the lighter object than the black hole, which normally sends also the gamma- or X-rays. 

The high-energy gamma- or X-ray radiation would normally uncover the black hole. In usual cases, those high-energy radiation bursts would be forming when some particles like planets are dropping in the singularity. And they are sending the Gamma- or X-ray radiation as the "goodbye". 

Also, neutron stars could send the gamma or X-rays when they are colliding. But those cases are not very usual. So what might happen, when some object sends the radio bursts simultaneously to the Earth? We could think that this effect is causing because the direction of the FRB is chancing. And there is nothing, what could turn the black hole upside down. So could the sender of that radio signal some kind of neutron star? 

The possibility is that the situation is like in the image above this text, where the orbiting object will cover the sender of the radio burst. But the problem is that the signal is extremely powerful, and one explanation could be that the signal from the neutron star travels through the powerful magnetic field, which increases the power of the FRB.

Could the reason for that signal some object, what poles change their direction in a certain period? 

There is a possibility that the thing, that causes this kind of signal is the neutron star, which would just turn to another side. In this case, the neutron star would send jets to a little bit asymmetrical trajectory, and the power of that jet would rotate the neutron star in a polar direction. That could be a good explanation if the signal comes from Milky Way. 

So when the jet is going out from the polar of the neutron star sloping. That thing would cause that the direction of the poles is changing. The jets would be acting like rockets, which are causing the turning of the neutron star opposite direction. 

Of course, the reason for the signal could be material that is dropping on some very heavy object. When the material is massing on the surface of the heavy object like a neutron star or white dwarf sooner or later there will happen the nuclear reaction. Or more accurate saying, the fusion reaction starts on the surface of that heavy object, what is used its fusion fuel 

Those explanations would be suitable and reasonable, but the problem is that the radio bursts are coming from some other galaxy. So that thing means that there should be a very powerful power source for that kind of radio burst.
