Parsec-scale jets driven by high-mass young stellar objects [PDF]
Astronomy & Astrophysics, 2018 Context. Protostellar jets in high-mass young stellar objects (HMYSOs) play a key role in the understanding of star formation and provide us with an excellent tool to study fundamental properties of HMYSOs. Aims.

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.

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.

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.

A search for ionized jets towards massive young stellar objects [PDF]
, 2016 Radio continuum observations using the Australia telescope compact array at 5.5, 9.0, 17.0 and 22.8 GHz have detected free-free emission associated with 45 of 49 massive young stellar objects and HII regions.

Black holes, disks, and jets following binary mergers and stellar collapse: The narrow range of electromagnetic luminosities and accretion rates. [PDF]
Physical review. D., 2017 We have performed magnetohydrodynamic simulations in general relativity of binary neutron star and binary black hole-neutron star mergers, as well as the magnetorotational collapse of supermassive stars. In many cases the outcome is a spinnng black hole (

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 ...

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 ...

The effects of the stellar wind and orbital motion on the jets of high-mass microquasars [PDF]
, 2016 High-mass microquasar jets propagate under the effect of the wind from the companion star, and the orbital motion of the binary system. The stellar wind and the orbit may be dominant factors determining the jet properties beyond the binary scales.} An ...
