Origin and Evolution of Large-scale Magnetic Fields [PDF]
, 2015 Magnetic elds are ubiquitous at all scales in the Universe and have been observed in galaxies and clusters of galaxies via observations of di use radio emission and Faraday Rotation Measures.

A complete redshift sample of galaxies [PDF]
, 1983 The role of complete redshift samples is discussed with particular attention focused on the need for new deeper and better controlled surveys for statistical clustering and dynamical studies.

A Full Accounting of the Visible Mass in SDSS MaNGA Disk Galaxies
The Astrophysical JournalWe present a study of the ratio of visible mass to total mass in spiral galaxies to better understand the relative amount of dark matter present in galaxies of different masses and evolutionary stages.

, 2014 A maximum jet efficiency line R similar to 25 (R = L-jet/L-bol), found in FRII radio galaxies by Fernandes et al., was extended to cover the full range of jet power by Punsly.

An investigation of the active galaxies M82 and NGC 5128 [PDF]
, 1995 In this thesis we present multi-waveband imaging polarimetry and spectropolarime- try of the starburst galaxy M82 and multi-waveband imaging polarimetry of the active galaxy NGC 5128. A review of previous studies of these galaxies is given.

The First Quenched Galaxies: When and How?
The Astrophysical Journal LettersMany quiescent galaxies discovered in the early Universe by JWST raise fundamental questions on when and how these galaxies became and stayed quenched. Making use of the latest version of the semianalytic model GAEA that provides good agreement with the ...

Counter-Rotation in Disk Galaxies
, 2014 Counter-rotating galaxies host two components rotating in opposite directions with respect to each other. The kinematic and morphological properties of lenticulars and spirals hosting counter-rotating components are reviewed. Statistics of the counter-rotating galaxies and analysis of their stellar populations provide constraints on the formation ...

Evolution of galactic disks and spheroids [PDF]
, 2004 In this Thesis the structural properties of galaxies using quantitative 2-dimensional bulge to disk decompositions are analysed across a range of environments and red- shifts.

The relationship between Gas and Galaxies [PDF]
, 2009 We have investigated the 2D 2-point correlation function, ƐAG, between low column density Lya absorbers and galaxies at a redshift z ~ 1 for the first time.

The Astrophysical JournalWe explore the relationship between galaxy structure, stellar mass, and local galaxy density in three SpARCS clusters at z ∼ 1.6 and compare with field galaxies from the 3D-HST survey.
