Environmental Dependence of the Nature of Gaseous Envelopes of Galaxies
نویسندگان
چکیده
We present new statistical study on the origin of Lyα absorption systems that are detected in QSO fields. The primary objective is to investigate environmental dependence of the relationship between galaxies and Lyα absorption systems. We find that galaxies exhibit no environmental dependence in giving rise to Lyα absorbers in their halos. Conversely, Lyα absorbers do not exhibit preference as to the environment where they reside.

Green envelopes classification: the comparative analysis of efficient factors on the thermal and energy performance of green envelopes
This paper classifies green envelopes as green roofs and green walls according to effective factors, which were derived from literature to compare the green envelopes’ thermal and energy performance in a more effective way. For this purpose, an extensive literature review was carried out by searching keywords in databases and studying related journal papers and articles. The research meth...
متن کاملProperties of a Chemically Enriched Ly α Absorption System at z = 0 . 167 and Implications for the Total Baryons
We present a detailed analysis of the chemical abundances, ionization state, and origin of a partial Lyman limit system (N(H I) ≈ 10 cm) at low redshift (z = 0.167 towards PKS0405−1219). We also present the first estimate of the total baryons in extended gaseous envelopes around galaxies based on a simple photoionization model for the Lyα absorbers. We find that extended gaseous envelopes can e...

In this paper we consider a gaseous detector and supposed, because of pass of an ionizing radiation, an electron created inside it. By numerical simulation with monte carlo method and concluding the impacts, scatterings and creation of secondary electrons, we find the trajectory of initial and secondary electrons. Dependence of number of secondary electrons to applied electrical field is invest...
متن کاملTHE ORIGIN OF Lyα ABSORPTION SYSTEMS AT z > 1—IMPLICATIONS FROM THE HUBBLE DEEP FIELD
The Hubble Deep Field images have provided us with a unique chance to relate statistical properties of high-redshift galaxies to statistical properties of Lyα absorption systems. Combining an empirical measure of the galaxy surface density versus redshift with an empirical measure of the gaseous extent of galaxies, we predict the number density of Lyα absorption systems that originate in extend...
