Outflows from Star-Forming Galaxies in the Early Universe: Evolution from Double- to Single-Peaked Lyman-$ α$ Profiles Following Delayed Supernova Feedback
Lyman-$ α$ emission, which owing to its resonant nature strongly couples the emergent line profile to gas kinematics, has become a key observable for probing outflows from star-forming galaxies in the early universe. Typically, Lyman-$ α$ profiles are explained in terms of idealised expanding shell models, while empirically-motivated interpretations of Lyman-$ α$ profiles that make use of comparisons with kinematics revealed by other spectral features (e.g. metal emission and absorption line…

Many people are detained at U.S. airports for reasons they find arbitrary and mysterious.
I got lucky—when I was stopped by Customs and Border Protection last week, after flying to Los Angeles from Melbourne, a border agent told me, explicitly and proudly, why I’d been pulled out of the customs line.
“Look, we both know why you are here,” the agent told me.
He identified himself to me as Adam, though his colleagues referred to him as Officer Martinez.
When I said that…

Unified Origin of Curvature Perturbation and Baryon Asymmetry of the Universe
We propose a unified framework that describes both the curvaton mechanism for generating primordial density fluctuations and the Affleck-Dine (AD) mechanism for baryogenesis. By introducing a complex scalar field (AD field) carrying a baryon/lepton number and its potential consisting of quadratic and quartic terms with a small baryon/lepton-number-violating mass term, we investigate the evolution of the scalar field during the radiation-dominated era following inflation. We set the initial cond…
