Gas-rich Local Dwarf Star-forming Galaxies and Their Connection with the Distant Universe
نویسنده
چکیده
I discuss the properties of gas-rich forming galaxies. I particularly emphasize the latest results on Lyα emission that are relevant to the search of distant young galaxies. The interdependance of the Lyα escape with the properties of the ISM in starburst galaxies is outlined. A new model from G. Tenorio-Tagle and his collaborators explain Lyα profiles in starburst galaxies from the hydrodynamics of superbubbles powered by massive stars. I stress again that since Lyα is primarely a diagnostic of the ISM, it is mandatory to understand how the ISM and Lyα are related to firmly relate Lyα to the cosmic star–formation rate.

Dwarf Galaxies: Important Clues to Galaxy Formation
The smallest dwarf galaxies are the most straight forward objects in which to study star formation processes on a galactic scale. They are typically single cell star forming entities, and as small potentials in orbit around a much larger one they are unlikely to accrete much (if any) extraneous matter during their lifetime (either intergalactic gas, or galaxies) because they will typically lose...
متن کاملStellar Populations in the Central Galaxies of Fossil Groups
It is inferred from the symmetrical and luminous X-ray emission of fossil groups that they are mature, relaxed galaxy systems. Cosmological simulations and observations focusing on their dark halo and inter-galactic medium properties confirm their early formation. Recent photometric observations suggest that, unlike the majority of non-fossil brightest group galaxies (BGGs), the central early-t...
متن کاملThe Star Formation History of Damped Lyman Alpha Absorbers
The local power law relationship between the surface densities of neutral hydrogen gas and star formation rate (SFR) can be used to explore the SFR properties of damped Lyman α (DLA) systems at higher redshift. We find that while the SFR densities for DLA systems are consistent with luminous star forming galaxies at redshifts below z ≈ 0.6, at higher redshifts their SFR density is too low for t...
متن کاملThe Origin of Dwarf Ellipticals in the Virgo Cluster
We study the evolution of dwarf (LH < 10 9.6 LH⊙) star forming and quiescent galaxies in the Virgo cluster by comparing their UV to radio centimetric properties to the predictions of multizone chemospectrophotometric models of galaxy evolution especially tuned to take into account the perturbations induced by the interaction with the cluster intergalactic medium. Our models simulate one or mult...
متن کاملInterstellar Media in the Magellanic Clouds and other Local Group Dwarf Galaxies
I review the properties of the interstellar medium in the Magellanic Clouds and Local Group dwarf galaxies. The more massive, star-forming galaxies show a complex, multi-phase ISM full of shells and holes ranging from very cold phases (a few 10 K) to extremely hot gas (> 10 K). In environments with high UV radiation fields the formation of molecular gas is suppressed, while in dwarfs with low U...
