Question about the toroidal magnetic field in quasars and the role of an ergosphere
1) Introduction
Most of astrophysical bodies (in this context: formed stars, young stellar objects and black holes) produce or are immersed in a non-zero magnetic field $\vec{B}$. It is common, since ...

Optical emission seen in Relativistic Jets from Quasars
So, I came across a very exciting paper on arXiv today. Here, they talk about the Hubble Space Telescope (HST) imaging of the host galaxy of the very first known quasar- 3C 273. My question is related ...

Why the Sun does not shoot relativistic jets?
I saw the features of the Sun here and it has almost everything include nanojets and CME but not relativistic jets. Isn't the Sun magnetically active so why isn't it capable of shooting out ...

Is creation of quark-gluon plasma endothermic?
When we create quark-gluon plasma in a lab by colliding lead nuclei, does releasing the nuclear bonds give us energy? Or take it?
An astrophysical jet could be as hot as 10 trillion K:

Jet streams from black holes - how can they be emitted? [duplicate]
I have seen many models showing the jet-streams shot out of black holes, and even some images. However, it is always said that a black hole has so strong of a gravity field, that not even light can ...

Does a white hole forms accretion disk?
A white is time reversal of a blackhole at least mathematically, I know it can't exist but may I know if it can form accretion disc similar to those stellar mass black holes. Does it spins on it's ...

Does the event when two BH without polar jets merge, cause a short living polar jet on the newly formed BH?
Does the event when two BH without polar jets merge, cause a short living polar jet on the newly formed BH? As BH need infalling material to activate their polar bursts does the BH falling into ...

Question about the Blandford-Znajek process
In the Blandford-Znajek Process (which is considered a potential mechanism to explain jets from AGN), the lorentz force is assumed to be vanishing (the force-free condition).
But we see that the ...

Has it been observed so far an object moving towards a BH along the trajectory of the polar astrophysical jet?
If we assume that the cause of the astrophysical jet is the magnetism of the BH than an object falling towards the BH in counterdirection of 'polar jet' emitions should not feel any strong deflection ...

Calculating Diagrams with Wilson Lines to One Loop
I have a question concerning the calculation of amplitudes containing Wilson lines.
I want to calculate the jet function defined by equation (3.3) from this paper.
$$\mathcal{J}(\text{arguments})u_s(p)...

Is there comprehensive catalogue of black holes and relativistic jets?
Basically I am looking for a database with RJs and BHs characteristics.
In High Energy Physics there is Particle Data Group book which is updated regularly. Is there something similar?

Help in understanding how general relativity describes space-time near black hole poles that emit astrophysical jets
I am aware that General relativity does not explicitly deal with 'expanding' or growing and due to that reason 'cosmologically pressurised' aether (proposed by the 'Theory of a river flow' but that ...

What would happen to a star caught in the path of an astrophysical jet?
The question pretty much captures it. What would happen to a star caught in the path of an astrophysical jet? I imagine the distance to the source of the jet, and the power of the source, matter most ...

Has an object been observed falling inside the black hole in direction antiparallel to an astrophysical jet?
Has an object been observed falling inside the black hole in direction antiparallel to an astrophysical jet? I do not know if the jet is fighting against gravity or not so will that part around the ...

Why does relativity affect relativistic jets?
Relativistic jets are regions outside black holes where matter is spewed out.
Wikipedia states that these jets will demonstrate relativistic effect such as relativistic beaming. I don't understand why ...
