Ultrafast Imaging of the Jahn-Teller Topography in Carbon Tetrachloride
(2023)Journal of the American Chemical SocietyWe report the direct time-domain observation of ultrafast dynamics driven by the Jahn-Teller effect. Using time-resolved photoelectron spectroscopy with a vacuum-ultraviolet femtosecond source to prepare high-lying Rydberg states of carbon tetrachloride, our measurements reveal the local topography of a Jahn-Teller conical intersection. The pump pulse prepares a configurationally mixed superposition of the degenerate 1T2 4p-Rydberg states, ...Journal Article -
Euclid preparation: II. the EUCLIDEMULATOR - a tool to compute the cosmology dependence of the nonlinear matter power spectrum
(2019)Monthly Notices of the Royal Astronomical SocietyWe present a new power spectrum emulator named EuclidEmulator that estimates the nonlinear correction to the linear dark matter power spectrum depending on the six cosmological parameters ωb, ωₘ, nₛ, h, w₀, and σ₈. It is constructed using the uncertainty quantification software UQLab using a spectral decomposition method called polynomial chaos expansion. All steps in its construction have been tested and optimized: the large high-resolution ...Journal Article -
AGN photoionization of gas in companion galaxies as a probe of AGN radiation in time and direction
(2019)Monthly Notices of the Royal Astronomical SocietyWe consider active galactic nucleus (AGN) photoionization of gas in companion galaxies (cross-ionization) as a way to sample the intensity of AGN radiation in both direction and time, independent of the gas properties of the AGN host galaxies. From an initial set of 212 AGN+companion systems, identified with the help of Galaxy Zoo participants, we obtained long-slit optical spectra of 32 pairs that were a priori likely to show cross-ionization ...Journal Article -
Radio Galaxy Zoo: CLARAN - a deep learning classifier for radio morphologies
(2019)Monthly Notices of the Royal Astronomical SocietyThe upcoming next-generation large area radio continuum surveys can expect tens of millions of radio sources, rendering the traditional method for radio morphology classification through visual inspection unfeasible. We present CLARAN — Classifying Radio sources Automatically with Neural networks — a proof-of-concept radio source morphology classifier based upon the Faster Region-based Convolutional Neutral Networks method. Specifically, ...Journal Article -
The Inner Workings of Crustal Distillation Columns; the Physical Mechanisms and Rates Controlling Phase Separation in Silicic Magma Reservoirs
(2019)Journal of PetrologyIgneous processes have a fundamental impact on how our planet is shaped: they contribute to the growth of continents, control volcanic activity, form ore deposits and supply most volatile elements to our atmosphere. In the course of this igneous differentiation, phase separation plays a key role, as in all distillation processes. How, and how fast, this phase separation occurs are therefore critical questions to address to better understand ...Journal Article -
More out of less: an excess integrated Sachs-Wolfe signal from supervoids mapped out by the Dark Energy Survey
(2019)Monthly Notices of the Royal Astronomical SocietyThe largest structures in the cosmic web probe the dynamical nature of dark energy through their integrated Sachs–Wolfe imprints. In the strength of the signal, typical cosmic voids have shown good consistency with expectation AISW = ΔTdata/ΔTtheory = 1, given the substantial cosmic variance. Discordantly, large-scale hills in the gravitational potential, or supervoids, have shown excess signals. In this study, we mapped out 87 new ...Journal Article
