A Measurement of W+jets Z+jets with the ATLAS Detector [PDF]
, 2015 PhDA study is presented on the production of vector boson (W and Z0) events in association with recoiling hadronic activity in the form of hadronic jets, using proton-proton collisions at the LHC.

Density Profiles of Collapsed Rotating Massive Stars Favor Long Gamma-Ray Bursts
The Astrophysical Journal Letters, 2023 Long-duration gamma-ray bursts (lGRBs) originate in relativistic collimated outflows—jets—that drill their way out of collapsing massive stars. Accurately modeling this process requires realistic stellar profiles for the jets to propagate through and ...

Magnetic Fields in Stellar Jets [PDF]
The Astrophysical Journal, 2007 Although several lines of evidence suggest that jets from young stars are driven magnetically from accretion disks, existing observations of field strengths in the bow shocks of these flows imply that magnetic fields play only a minor role in the dynamics at these locations. To investigate this apparent discrepancy we performed numerical simulations of

Collapsar Black Holes Are Likely Born Slowly Spinning
The Astrophysical Journal Letters, 2023 Collapsing stars constitute the main black hole (BH) formation channel, and are occasionally associated with the launch of relativistic jets that power γ -ray bursts (GRBs). Thus, collapsars offer an opportunity to infer the natal (before spin-up/down by

Power-law Distribution of Solar Cycle–modulated Coronal Jets
The Astrophysical Journal Supplement Series, 2023 Power-law distributions have been studied as a significant characteristic of nonlinear dissipative systems. Since discovering the power-law distribution of solar flares that was later extended to nanoflares and stellar flares, it has been widely accepted

Theory of Stellar and Extragalactic Jets [PDF]
International Astronomical Union Colloquium, 1986 AbstractDifferent types of astrophysical jets are briefly described and the wide differences in their observed properties are emphasized. Various physical mechanisms that have been proposed for creating jets, based on gas dynamical, magnetic, and radiative stresses are briefly reviewed. It is argued that magnetic fields are probably generally important

Bipolar Outflows and Stellar Jets [PDF]
Symposium - International Astronomical Union, 1987 A wealth of data is now available on the energetic mass outflows that are associated with young stellar objects. This phenomenon is thought to occur at a very early stage in the evolution of stars of almost all masses. The discovery of this energetic event was first made through observations of the rapidly expanding molecular gas that surrounds many of
