The phenomenology of jets in astrophysics
Webb26 jan. 2012 · A key point missing in the aforementioned rich phenomenology is a physical explanation of the jet appearance, disappearance, and re-appearance as the sources follow a “q”-shaped curve in the so-called hardness-intensity diagram (HID, first introduced in the present context by Miyamoto et al. 1995; Fig. 1 1).
The phenomenology of jets in astrophysics
Did you know?
An astrophysical jet is an astronomical phenomenon where outflows of ionised matter are emitted as an extended beam along the axis of rotation. When this greatly accelerated matter in the beam approaches the speed of light, astrophysical jets become relativistic jets as they show effects from special … Visa mer Relativistic jets are beams of ionised matter accelerated close to the speed of light. Most have been observationally associated with central black holes of some active galaxies, radio galaxies or quasars, … Visa mer Jets may also be observed from spinning neutron stars. An example is pulsar IGR J11014-6103, which has the largest jet so far observed in the Milky Way, and whose velocity is estimated at 80% the speed of light (0.8c). X-ray observations have been obtained but there is … Visa mer • Accretion disk • Bipolar outflow • Blandford–Znajek process • CGCG 049-033, elliptical galaxy located 600 million light-years from Earth, known for having the longest galactic jet discovered Visa mer Because of the enormous amount of energy needed to launch a relativistic jet, some jets are possibly powered by spinning Visa mer • Illustration of the dynamics of a proplyd, including a jet • Centaurus A in x-rays showing the relativistic jet Visa mer • NASA – Ask an Astrophysicist: Black Hole Bipolar Jets • SPACE.com – Twisted Physics: How Black Holes Spout Off • Blandford, Roger; Agol, Eric; Broderick, Avery; Heyl, Jeremy; … Visa mer WebbAstrophysical jets play an important feedback role in the evolution of their host systems.

WebbOne of the challenges of collider physics is to unambiguously associate detector-based objects with the corresponding elementary physics objects. A particular example is the association of calorimeter-based objects such as “jets,” identified with a standard (IR-safe) jet algorithm, with the underlying physics objects, which may be QCD-jets (arising from a …
