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 ...

The fastest components in stellar jets
Bulletin of the American Astronomical Society, 2019 Outflows and jets are a crucial component of the star formation process. The innermost components of those jets are launched close to the star and thus probe the connection between star, disk, and magnetic field. Observations with high spatial resolution in the UV and X-rays are required to probe these fast winds.

Fictions, Conditionals, and Stellar Astrophysics [PDF]
, 2013 This article argues in favour of an inferential role for fictions in scientific modelling. The argument proceeds by means of a detailed case study, namely models of the internal structure of stars in stellar astrophysics.

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 ...

Turbulence Driven by Stellar Jets, the Possibility and the Efficiency [PDF]
The Astrophysical Journal, 2019 Abstract We investigate the feedback of the stellar jets on the surrounding interstellar gas based on 2D and 3D simulations applying HD and MHD modules of the PLUTO 4.2 code. The main question we address is whether the stellar jet can be considered as a turbulence driver into the interstellar gas.

UNIFYING THE ZOO OF JET-DRIVEN STELLAR EXPLOSIONS [PDF]
The Astrophysical Journal, 2012 We present a set of numerical simulations of stellar explosions induced by relativistic jets emanating from a central engine sitting at the center of compact, dying stars. We explore a wide range of durations of the central engine activity, two candidate stellar progenitors, and two possible values of the total energy release.

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.

Jets in Quasi-stellar Objects [PDF]
Nature, 1968 McCREA1 has raised the interesting possibility that the line spectrum from quasi-stellar objects could arise from a jet aimed toward the observer. McCrea states that this sort of model avoids the intergalactic absorption of Lyman α from 3C9 predicted by Gunn and Peterson2 if the density of neutral intergalactic hydrogen at z = 2 is of the order of 10 ...

Influence of surface stressing on stellar coronae and winds [PDF]
, 2013 STFC funding has supported this research.The large-scale field of the Sun is well represented by its lowest energy (or potential) state. Recent observations, by comparison, reveal that many solar-type stars show large-scale surface magnetic fields that ...
