AGN Jet Mass Loading and Truncation by Stellar Winds [PDF]
, 2006 Active Galactic Nuclei can produce extremely powerful jets. While tightly collimated, the scale of these jets and the stellar density at galactic centers implies that there will be many jet/star interactions, which can mass-load the jet through stellar ...

Supernova Hosts for Gamma-Ray Burst Jets: Dynamical Constraints [PDF]
, 2002 I constrain a possible supernova origin for gamma-ray bursts by modeling the dynamical interaction between a relativistic jet and a stellar envelope surrounding it.

A Global Inventory of Feedback
Galaxies, 2023 Feedback from both supermassive black holes and massive stars plays a fundamental role in the evolution of galaxies and the inter-galactic medium. In this paper, we use available data to estimate the total amount of kinetic energy and momentum created ...

Are jets rotating at the launching? [PDF]
, 2009 I argue that the Doppler shift asymmetries observed in some young stellar object (YSO) result from the interaction of the jets with the circumstellar gas, rather than from jets' rotation.

Relativistic stellar jets: dynamics and non-thermal radiation
EPJ Web of Conferences, 2013 Relativistic stellar jets, produced in binary systems called microquasars, propagate through media with different spatial scales releasing their energy in the form of work and radiation from radio to gamma rays.

A model for high-mass microquasar jets under the influence of a strong stellar wind [PDF]
, 2019 Context. High-mass microquasars (HMMQs) are systems from which relativistic jets are launched. At the scales of several times the binary system size, the jets are expected to follow a helical path caused by the interaction with a strong stellar wind and ...

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

Low- and High-energy Neutrinos from SN 2023ixf in M101
The Astrophysical Journal Letters, 2023 Supernova (SN) 2023ixf in M101 is the closest SN explosion observed in the last decade. Therefore, it is a suitable test bed to study the role of jets in powering the SN ejecta.

Cosmic Feedback from AGN [PDF]
, 2009 Accretion onto the massive black hole at the centre of a galaxy can feed energy and momentum into its surroundings via radiation, winds and jets. Feedback due to radiation pressure can lock the mass of the black hole onto the M-sigma relation, and shape ...

Simulations of Gamma-Ray Emission from Magnetized Microquasar Jets
Advances in High Energy Physics, 2018 In this work, we simulate γ-rays created in the hadronic jets of the compact object in binary stellar systems known as microquasars. We utilize as the main computational tool the 3D relativistic magnetohydrodynamical code PLUTO combined with in-house ...
