Jet collimation refers to the process by which astrophysical jets, typically emitted by objects like black holes or neutron stars, become narrowly focused and maintain a coherent structure over vast distances. This phenomenon is crucial for understanding the dynamics of high-energy astrophysical environments and the mechanisms behind energy transfer in the universe.

Jet Collimation

Astrophysical jets are highly collimated streams of plasma ejected at relativistic speeds from the vicinity of compact objects like black holes and neutron stars, often observed in active galactic nuclei and young stellar objects. These jets are significant for their role in transporting energy and matter across vast cosmic distances, influencing galaxy formation and evolution.

Astrophysical Jets

Black holes are regions in space where the gravitational pull is so strong that nothing, not even light, can escape from them. They are formed when massive stars collapse under their own gravity at the end of their life cycles, leading to singularities surrounded by an event horizon.

Black Holes

Neutron stars are the remnants of massive stars that have undergone supernova explosions, resulting in an incredibly dense object primarily composed of neutrons. They exhibit extreme gravitational and magnetic fields, and their study provides insights into fundamental physics and the behavior of matter under extreme conditions.

Neutron Stars

A coherent structure is a spatially and temporally organized pattern within a turbulent flow that significantly influences the dynamics and transport properties of the fluid. These structures are crucial for understanding and predicting complex fluid behaviors in natural and engineered systems.
