Understanding Nlr in Seyfert Galaxies: Numerical Simulation of Jet-cloud Interaction
نویسندگان
چکیده
Observaciones recientes con el HST sugieren que la NLR de las galaxias Seyfert puede ser el resultado de la interacción entre un chorro de plasma y un medio inhomogéneo. Con esta idea hacemos simulaciones numéricas de la colisión de un chorro radiativo con una nube densa. Se utiliza un código hidrodinámico con un tratamiento simple de los procesos radiativos, que permite estudiar los detalles de la hidrodinámica con una interpretación cualitativamente buena de los procesos de emisión. Nuestros tres objetivos principales son (i) reproducir en las simulaciones las condiciones observadas, (ii) deducir restricciones de los parámetros del chorro y (iii) estudiar la capacidad del chorro para fotoionizar al medio circundante.

Understanding narrow line regions in Seyfert galaxies: Numerical simulation of jet-cloud interaction
Recent HST observations suggest that the NLR in Seyfert Galaxies can be the result of interaction between jet and external inhomogeneous medium; following this suggestion we perform numerical simulations considering the impact of a radiative jet on a dense cloud. We approach the problem adopting a hydrodynamical code, that allows us to study in detail the jet hydrodynamics, while we choose a mo...
متن کاملJet-cloud interactions and the brightening of the narrow line region in Seyfert galaxies
We study the kinematical and brightness evolution of emission line clouds in the narrow line region (NLR) of Seyfert galaxies during the passage of a jet. We derive a critical density above which a cloud remains radiative after compression by the jet cocoon. The critical density depends mainly on the cocoon pressure. Super-critical clouds increase in emission line brightness, while sub-critical...
متن کاملPhysical Conditions in the Narrow - Line Region Of
We have investigated the physical conditions in the narrow-line region (NLR) of M51 using long-slit spectra obtained with the Space Telescope Imaging Spectrograph (STIS) aboard the Hubble Space Telescope (HST) and 3.6 cm radio continuum observations obtained with the Very Large Array (VLA)2. Emission-line diagnostics were employed for nine NLR clouds, which extend 2.5 (102 pc) from the nucleus,...
متن کاملJet Cocoons and the Formation of Narrow Line Clouds in Seyfert Galaxies
We present non-adiabatic hydrodynamic simulations of a supersonic light jet propagating into a fully ionized medium of uniform density on a scale representative of the narrow line region (NLR) in Seyfert galaxies with associated radio jets. In this regime the cooling distance of the swept up gas in the bowshock of the jet is of the same order as the transverse extent of the jet bowshock, as opp...
متن کاملAre Seyfert Narrow Line Regions Powered by Radio Jets?
We argue that the narrow line regions of Seyfert galaxies are powered by the transport of energy and momentum by the radio-emitting jets. This implies that the ratio of the radio power to jet energy flux is much smaller than is usually assumed for radio galaxies. This can be partially attributed to the smaller ages (∼ 106 yrs) of Seyferts compared to radio galaxies but one also requires that ei...
