Calabi-Yau Genus-One Fibrations and Twisted Dimensional Reductions of F-theory
Lara B. Anderson, James Gray, Paul-Konstantin Oehlmann
In this brief note we explore the space of genus one and elliptic fibrations within CY manifolds, their organizing principles, and how they relate to the set of all CY manifolds. W…
Twisted Fibrations in M/F-theory
Lara B. Anderson, James Gray, Paul-Konstantin Oehlmann
In this work we investigate 5-dimensional theories obtained from M-theory on genus one fibered threefolds which exhibit twisted algebras in their fibers. We provide a base-independ…
Branes and Bundles through Conifold Transitions and Dualities in Heterotic String Theory
Lara B. Anderson, Callum R. Brodie, James Gray
Geometric transitions between Calabi-Yau manifolds have proven to be a powerful tool in exploring the intricate and interconnected vacuum structure of string compactifications. How…
Vanishing Yukawa Couplings and the Geometry of String Theory Models
Lara B. Anderson, James Gray, Magdalena Larfors +1
We provide an overview of recent work which aims to understand patterns of vanishing Yukawa couplings that arise in models of particle physics derived from string theory. These pat…
Generalized Vanishing Theorems for Yukawa Couplings in Heterotic Compactifications
Lara B. Anderson, James Gray, Magdalena Larfors +2
Heterotic compactifications on Calabi-Yau threefolds frequently exhibit textures of vanishing Yukawa couplings in their low energy description. The vanishing of these couplings is…
The optical-UV emissivity of quasars: dependence on black hole mass and radio loudness
Francesco Shankar, Giorgio Calderone, Christian Knigge +15
We analyzed a large sample of radio-loud and radio-quiet quasar spectra at redshift 1.0 < z < 1.2 to compare the inferred underlying quasar continuum slopes (after removal of the h…
