Coupled Geodynamical‐Geochemical Perspectives on the Generation and Composition of Mid‐Ocean Ridge Basalts

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 2, February 2024.
Abstract Owing to their abundance and relative availability on Earth's seafloor, mid‐ocean ridge basalts (MORBs) have a well‐defined chemical element budget, reflected by the low standard deviation associated with typical normal MORB (N‐MORB) composition. However, the exact mechanisms leading to magma differentiation and MORB generation remain debated,

Angular ellipticity correlations in a composite alignment model for elliptical and spiral galaxies and inference from weak lensing

, 2018
We investigate a physical, composite alignment model for both spiral and elliptical galaxies and its impact on cosmological parameter estimation from weak lensing for a tomographic survey. Ellipticity correlation functions and angular ellipticity spectra

Non-parametric inversion of gravitational lensing systems with few images using a multi-objective genetic algorithm

, 2007
Galaxies acting as gravitational lenses are surrounded by, at most, a handful of images. This apparent paucity of information forces one to make the best possible use of what information is available to invert the lens system.

Modeling CMB Lensing Cross Correlations with {\sc CLEFT}

, 2017
A new generation of surveys will soon map large fractions of sky to ever greater depths and their science goals can be enhanced by exploiting cross correlations between them.

Primordial Bispectrum Information from CMB Polarization

, 2004
After the precise observations of the Cosmic Microwave Background (CMB) anisotropy power spectrum, attention is now being focused on the higher order statistics of the CMB anisotropies.

Unveiling the Dynamics of the Universe

, 2016
We explore the dynamics and evolution of the Universe at early and late times, focusing on both dark energy and extended gravity models and their astrophysical and cosmological consequences.

Evolution of intrinsic ellipticity correlations due to peculiar motion

, 2012
Topic of this paper is the time-evolution of intrinsic correlations of galaxy ellipticities due to peculiar motion. In our model, the galaxy ellipticities are determined from the angular momentum of their host haloes, which can be computed from the ...
