Emission Line Galaxies in Clusters
At the present epoch, clusters of galaxies are known to be a hostile environment for emission-line galaxies, which are more commonly found in low density regions outside of clusters. In contrast, going to higher redshifts the population of emission-line galaxies in clusters becomes progressively more conspicuous, and large numbers of star-forming late-type galaxies are observed. I present an ov...
متن کاملSpectral classification of emission-line galaxies from the Sloan Digital Sky Survey I. An improved classification for high redshift galaxies
Aims. We study the spectral classification of emission-line galaxies as star-forming galaxies or Active Galactic Nuclei (AGNs). From the Sloan Digital Sky Survey (SDSS) high quality data, we define an improved classification to be used for high redshift galaxies Methods. We classify emission-line galaxies of the SDSS according to the latest standard recipe using [OIII]λ5007, [NII]λ6584, [SII]λ6...
متن کاملH I observations of emission - line galaxies
We present single-dish Lovell telescope H i observations of a sample of 67 emission-line and UV-excess galaxies, of which 52 are taken from the University of Michigan (UM) catalogue. In addition, H i observations of 24 gas-rich irregular galaxies are presented. We find that emission-line galaxies are H i–rich with a median H i mass to blue luminosity ratio MHI /LB of ∼ 0.45 M /L . Within the UM...
متن کاملFabry-Perot Survey of Emission-Line Galaxies
The recent results from a deep Fabry-Perot survey of nearby active and star-forming galaxies are presented. Line-emitting material is detected over two orders of magnitude in galactocentric radius, from the 100-pc scale of the active or starbursting nucleus out to several 10s of kpc, sometimes well beyond the optical confines of the host galaxies. The excitation and dynamical properties of the ...
متن کاملCO line emission from Lyman break galaxies
Context. The detection of the rotational lines of CO in proto-galaxies in the early Universe provides one of the most promising ways of probing the fundamental physical properties of a galaxy, such as its size, dynamical mass, gas density, and temperature. While such observations are currently limited to the most luminous galaxies, the advent of ALMA will change the situation dramatically, resu...
