| contents | Physical properties of absorbers in high redshift quasars L. E. Simon F. W. Hamann M. Pettini Física, Astronomía y Matemáticas Recent studies based on quasar emission linessuggest that quasar environments are typicalymetal rich, with metallicities near or abovethe solar value at even the highest observedredshifts. Due to the large uncertainties in-herent in emission line abundance analysis,we employ another technique, absorption lineanalysis, to corroborate the evidence gleanedso far in order to better constrain the de-tected metallicities. We are also interested inthe physical nature of these absorbers, theirrelationship to quasar outows, and their rolein quasar-host galaxy evolution. 2007 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57102977 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.29 |
