Numerical study on the interaction of AGN winds and interstellar medium

open access: yesMonthly Notices of the Royal Astronomical Society
ABSTRACT Accretion disc winds can leave active galactic nuclei (AGNs) and interact with the interstellar medium (ISM) of their host galaxies. We perform two-dimensional numerical simulations to investigate the interaction of AGN winds and ISM.

W50 - a stellar-wind bubble in a three-phase interstellar medium? [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1983
L'interaction entre les jets relativistes de SS 433 et la nebuleuse radio W 50 est analysee sur la base d'observations recentes. On trouve que SS 433 pourrait etre entouree d'un milieu interstellaire nuageux, du type de celui decrit par le modele a 3 phases de McKee et Ostriker. W 50 est probablement une bulle interstellaire en expansion, entrainee par

An Anisotropic Plasma Model of the Heliospheric Interface

open access: yesThe Astrophysical Journal
We present a pioneering model of the interaction between the solar wind and the surrounding interstellar medium that includes the possibility of different pressures in directions parallel and perpendicular to the magnetic field.

Termination of the solar wind in the hot, partially ionized interstellar medium [PDF]

open access: yes, 1974
Theoretical foundations for understanding the problem of the termination of the solar wind are reexamined in the light of most recent findings concerning the states of the solar wind and the local interstellar medium.

Scaling Relations of Galactic Outflows across Cosmic Time: New Insights from Cosmic Noon

open access: yesThe Astrophysical Journal
Galactic outflows play a significant role in regulating galaxy evolution. Scaling relations between stellar mass ( M _⋆ ), star formation rate (SFR), and outflow properties have been extensively studied at low redshifts ( z   50 for H α or [O iii ] λ ...

The Interstellar Medium

open access: yes, 2005
Describing interstellar matter in our galaxy in all of its various forms, this book also considers the physical and chemical processes that are occurring within this matter.

Distance to the IBEX Ribbon beyond the Heliopause

open access: yesThe Astrophysical Journal
Our understanding of the solar–interstellar interaction greatly improved with measurements of energetic neutral atoms (ENAs) from the outer heliosphere by NASA’s Interstellar Boundary Explorer (IBEX).

WawHelioIonMP: A Semiempirical Tool for the Determination of Latitudinal Variation in the Ionization Rate of Interstellar Hydrogen and the Solar Wind

open access: yesThe Astrophysical Journal
The latitudinal structure of the solar wind varies during the cycle of solar activity. Analysis of this variation is important for understanding the solar activity and interpretation of observations of heliospheric energetic neutral hydrogen atoms and ...

Optimal Management of a Wind/CAES Power Plant by means of Neural Network Wind Speed Forecast

open access: yes, 2007
Some of the major limitations of renewable energy sources are represented by their low power density and intermittent nature, largely depending upon local site and unpredictable weather conditions. These problems concur to increase the unit costs of wind

First Resolution of a Main-sequence G star’s Astrosphere Using Chandra

open access: yesThe Astrophysical Journal
We report the resolution of a halo of X-ray line emission surrounding the zero-age main-sequence G8.5V star HD 61005 by Chandra/ACIS-S. Located only ∼36 pc distant, HD 61005 is young (100 ± 50 Myr) and X-ray bright (∼300 × solar), observed with a nearly ...
