The content of astrophysical jets
(Wiley VCH Verlag, 2021-06)
Jets, collimated outflows of particles and fields, are observed in a wide variety of astrophysical systems, including Active Galactic Nuclei of various types, micro-quasars, gamma-ray bursts, and young stellar objects. ...
The origin of matter at the base of relativistic jets in active galactic nuclei
(Multidisciplinary Digital Publishing Institute, 2020-07-18)
The generation of relativistic jets in active sources such as blazars is a complex problem with many aspects, most of them still not fully understood. Relativistic jets are likely produced by the accretion of matter and ...
Nonthermal emission and particle acceleration in protostellar jets
(Publications of the Astronomical Society of the Pacific, 2018-11)
The presence of non thermal emission detected at radio frequencies in some protostellar jets, constitutes a remarkable discovery with very imporant implications: (1) these low energy systems should be able to accelerate ...
Non-thermal emission resulting from a supernova explosion inside an extragalactic jet
(EDP Sciences, 2019-02)
Context. Core-collapse supernovae are found in galaxies with ongoing star-formation. In a starburst galaxy hosting an active galactic nucleus with a relativistic jet, supernovae can take place inside the jet. The collision ...
The Highly Collimated Radio Jet of HH 80-81: Structure and Nonthermal Emission
(IOP Publishing, 2017-12)
Radio emission from protostellar jets is usually dominated by free-free emission from thermal electrons. However, in some cases, it has been proposed that nonthermal emission could also be present. This additional contribution ...
Approximate Next-to-Next-to-Leading Order Corrections to Hadronic Jet Production
(American Physical Society, 2014-02)
We determine dominant next-to-next-to-leading order QCD corrections to single-inclusive jet produc- tion at the LHC and Tevatron, using the established threshold resummation framework. In contrast to previous literature ...
Axis-switching of a micro-jet
(American Institute of Physics, 2014-03)
In this study, it is shown that free microjets can undergo complex transitions similar to large-scale free jets despite relatively low Reynolds numbers. Using an original experimental method allowing for the 3D reconstruction ...
Neutron escape from microquasar jets
(Asociación Argentina de Astronomía, 2020-08)
The launching mechanism and composition of astrophysical jets are still open problems. If relativistic protons are present in these jets, then energetic neutrons should be produced. Since neutrons are not affected by ...
Jet production in polarized deep inelastic scattering at next-to-next-to-leading order
(American Physical Society, 2020-08)
We present the next-to-next-to-leading order (NNLO) calculation for single-inclusive jet production in polarized deep inelastic lepton-nucleon scattering e→p→→jet+X. We perform the computation based on the projection-to-Born ...
