Stellar-wind-blown Bubbles as Environments for Late-time Rebrightening of Gamma-ray Burst Afterglows

The Astrophysical Journal Letters
We present multiwavelength afterglow fitting results for three events that exhibit late afterglow rebrightening behavior: EP240414a ( z = 0.401), GRB 240529A ( z = 2.695), and GRB 240218A ( z = 6.782), which span a broad range of redshifts, from the ...

Powerful jets from accreting black holes: evidence from the optical and infrared

, 2010
A common consequence of accretion onto black holes is the formation of powerful, relativistic jets that escape the system. In the case of supermassive black holes at the centres of galaxies this has been known for decades, but for stellar-mass black ...

Quasar induced galaxy formation: a new paradigm ? [PDF]

, 2009
We discuss observational evidence that quasars play a key role in the formation of galaxies starting from the detailed study of the quasar HE0450-2958 and extending the discussion to a series of converging evidence that radio jets may trigger galaxy ...

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 ...

Discovery of a Collimated Jet from the Low-luminosity Protostar IRAS 16253−2429 in a Quiescent Accretion Phase with the JWST

The Astrophysical Journal Letters
Investigating Protostellar Accretion (IPA) is a JWST Cycle 1 GO program that uses NIRSpec integral field units and MIRI Medium Resolution Spectrograph to obtain 2.9–28 μ m spectral cubes of young, deeply embedded protostars with luminosities of 0.2–10 ...

Two-component jet simulations: II. Combining analytical disk and stellar MHD outflow solutions [PDF]

, 2009
Theoretical arguments along with observational data of YSO jets suggest the presence of two steady components: a disk wind type outflow needed to explain the observed high mass loss rates and a stellar wind type outflow probably accounting for the ...

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.

Jet-powered Turbulence in Common Envelope Evolution

The Astrophysical Journal, 2023
We conduct a three-dimensional hydrodynamical simulation of common envelope evolution (CEE) where a neutron star (NS) spirals in inside the envelope of a red supergiant star in a predetermined orbit.

On the interaction of jets with stellar winds in XRBs

, 2010
We present the first three-dimensional simulations of the evolution of a microquasar jet inside the binary-star system. The aim is to study the interaction of these jets with the stellar wind from a massive companion and the possible locations of high ...

Nonradial and nonpolytropic astrophysical outflows IX. Modeling T Tauri jets with a low mass-accretion rate

, 2011
Context: A large sample of T Tauri stars exhibits optical jets, approximately half of which rotate slowly, only at ten per cent of their breakup velocity.
