The impact and mitigation of broad absorption line quasars in Lyman forest correlations

Lauren Ennesser, Paul Martini, Andreu Font-Ribera +1

Correlations in and with the flux transmission of the Lyman (Ly) forest in the spectra of high-redshift quasars are powerful cosmological tools, yet these measurements can b…

Accuracy of power spectra in dissipationless cosmological simulations

Sara Maleubre, Daniel Eisenstein, Lehman H. Garrison +1

We exploit a suite of large \emph{N}-body simulations (up to N=) performed with \Abacus, of scale-free models with a range of spectral indices , to better understand and…

Gravitational collapse from cold uniform asymmetric initial conditions

Francesco Sylos Labini, Michael Joyce

Using controlled numerical N-body experiments, we show how, in the collapse dynamics of an initially cold and uniform distribution of particles with a generic asymmetric shape, fin…

The Twins Embedding of Type Ia Supernovae I: The Diversity of Spectra at Maximum Light

K. Boone, G. Aldering, P. Antilogus +34

We study the spectral diversity of Type Ia supernovae (SNe Ia) at maximum light using high signal-to-noise spectrophotometry of 173 SNe Ia from the Nearby Supernova Factory. We dec…

The Twins Embedding of Type Ia Supernovae II: Improving Cosmological Distance Estimates

K. Boone, G. Aldering, P. Antilogus +34

We show how spectra of Type Ia supernovae (SNe Ia) at maximum light can be used to improve cosmological distance estimates. In a companion article, we used manifold learning to bui…

Good and Proper: Self-similarity of N-body Simulations with Proper Force Softening

Lehman H. Garrison, Michael Joyce, Daniel J. Eisenstein

Analysis of self-similarity in scale-free -body simulations reveals the spatial and temporal scales for which statistics measured in cosmological simulations are converged to th…
