Journal ArticleDOI
Extragalactic magnetic fields
TL;DR: In this paper, the observational methods for detecting and measuring extragalactic magnetic fields are discussed, along with some new indirect methods which could be used for inferring field strengths at large redshifts which are otherwise beyond the reach of direct measurement.
Book
Cosmic Magnetic Fields
TL;DR: Magnetic fields are important in the universe and their effects contain the key to many astrophysical phenomena that are otherwise impossible to understand as mentioned in this paper, and their interconnections to plasma processes, astroparticle physics, high energy astrophysics, and cosmic evolution.
Book ChapterDOI
Magnetic Fields and Faraday-Active Clouds out to the Distances of Quasars
TL;DR: In this paper, the authors review the evidence supporting the first detection of large scale magnetic fields in the universe out to redshifts of 2 and greater, and show some independent, new evidence which gives us some further, more direct clues concerning the nature of the extragalactic systems containing the magnetic fields which I and my collaborators have detected.
Chemical Evolution of High Redshift Galaxies

TL;DR: In this paper, the authors tried to determine the chemical evolution of high redshift galaxies from the observed redshift distribution of the heavy element absorption systems in the spectra of QSOs, taking into account the evolution in the intensity of the metagalactic UV ionizing radiation background.
