SMBH Spherically Symmetric Accretion Regulated by Violent Star Formation Feedback
S. Silich, F. Hueyotl-Zahuantitla, G. Tenorio-Tagle
The mounting evidence for violent nuclear star formation in Seyfert galaxies has led us to consider the hydrodynamics of the matter reinserted by massive stars through strong stell…
Spherically-symmetric Accretion onto a Black Hole at the Center of a Young Stellar Cluster
Sergiy Silich, Guillermo Tenorio-Tagle, Filiberto Hueyotl-Zahuantitla
We present a self-consistent, bimodal stationary solution for spherically symmetric flows driven by young massive stellar clusters with a central supermassive black hole. We demons…
On the origin of the neutral hydrogen supershells: the ionized progenitors and the limitations of the multiple supernovae hypothesis
Sergiy Silich, Federico Elias, José Franco
Here we address the question whether the ionized shells associated with giant HII regions can be progenitors of the larger HI shell-like objects found in the Milky Way and other sp…
The pressure confined wind of the massive and compact superstar cluster M82-A1
Sergiy Silich, Guillermo Tenorio-Tagle, Casiana Munoz-Tunon
The observed parameters of the young superstar cluster M82-A1 and its associated compact HII region are here shown to indicate a low heating efficiency or immediate loss, through r…
Super stellar clusters with a bimodal hydrodynamic solution: an Approximate Analytic Approach
R. Wunsch, S. Silich, J. Palous +1
We look for a simple analytic model to distinguish between stellar clusters undergoing a bimodal hydrodynamic solution from those able to drive only a stationary wind. Clusters in…
On the hydrodynamics of the matter reinserted within superstellar clusters
Guillermo Tenorio-Tagle, Richard Wunsch, Sergiy Silich +1
We present semi-analytical and numerical models, accounting for the impact of radiative cooling on the hydrodynamics of the matter reinserted as strong stellar winds and supernovae…
Super Massive Star Clusters: From Superwinds to a Cooling Catastrophe and the Re-processing of the Injected Gas
S. Silich, G. Tenorio-Tagle, C. Munoz-Tunon +1
Different hydrodynamic regimes for the gaseous outflows generated by multiple supernovae explosions and stellar winds occurring within compact and massive star clusters are discuss…
On the structure of giant HII regions and HII galaxies
G. Tenorio-Tagle, C. Munoz-Tunon, E. Perez +2
We review the structural properties of giant extragalactic HII regions and HII galaxies based on two dimensional hydrodynamic calculations, and propose an evolutionary sequence tha…
On the feedback from super stellar clusters. I. The structure of giant HII regions and HII galaxies
G. Tenorio-Tagle, C. Munoz-Tunon, E. Perez +2
We review the structural properties of giant extragalactic HII regions and HII galaxies based on 2D hydrodynamic calculations, and propose an evolutionary sequence that accounts fo…
On the neutral gas distribution and kinematics in the dwarf irregular galaxy IC 1613
Sergiy Silich, Tatyana Lozinskaya, Alexei Moiseev +4
We study the neutral hydrogen distribution and kinematics in the Local Group dwarf irregular galaxy IC 1613 and compare them with the ionized gas distribution and stellar content o…
On the X-ray Emission from Massive Star Clusters and their Evolving Superbubbles
Sergiy Silich, Guillermo Tenorio-Tagle, Gabriel Alejandro Anorve Zeferino
The X-ray emission properties from the hot thermalized plasma that results from the collisions of individual stellar winds and supernovae ejecta within rich and compact star cluste…
On the Extreme Positive Feedback Star-Forming Mode from Massive and Compact Superstar Clusters
Guillermo Tenorio-Tagle, Sergiy Silich, Ary Rodriguez Gonzalez +1
The force of gravity acting within the volume occupied by young, compact and massive superstar clusters, is here shown to drive in situ all the matter deposited by winds and supern…
Superstellar clusters and their impact on their host galaxies
Guillermo Tenorio-Tagle, Sergiy Silich, Casiana Munoz-Tunon
We review the properties of young superstellar clusters and the impact that their evolution has in their host galaxies. In particular we look at the two different star-forming feed…
On the extreme stationary outflows from super-star clusters: from superwinds to supernebulae and further massive star formation
Guillermo Tenorio-Tagle, Sergiy Silich, Ary Rodriguez-Gonzalez +1
The properties of star cluster winds in the supercritical, catastrophic cooling regime are discussed. We demonstrate that strong radiative cooling may inhibit superwinds and, after…
How old are the HII Galaxies?
Roberto Terlevich, Sergiy Silich, Daniel Rosa-Gonzalez +1
Using a novel approach we have reanalized the question of whether the extreme star forming galaxies known as HII galaxies are truly young or rejuvenated old systems. We first prese…
On the formation of massive stellar clusters
Guillermo Tenorio-Tagle, Jan Palous, Sergiy Silich +2
Here we model a star forming factory in which the continuous creation of stars results in a highly concentrated, massive (globular cluster-like) stellar system. We show that under…
Supergalactic winds driven by multiple superstar clusters
G. Tenorio-Tagle, S. Silich, C. Munoz-Tunon
We present two dimensional hydrodynamic calculations of free expanding supergalactic winds, taking into consideration strong radiative cooling. Our main premise is that supergalact…
