The SPace-based InterFerometer Feasibility (SPIFF) Project: Enabling Future High-Resolution Astronomy Across the EM Spectrum
Berke Vow Ricketti, Victoria Yankelevich, Chris Benson +19
A plethora of astronomical science cases can only be achieved with high angular resolution observations, and we can expect the number of these to grow as astronomers are constraine…
Euclid preparation. XCVIII. Cosmology Likelihood for Observables in Euclid (CLOE). 5: Extensions beyond the standard modelling of theoretical probes and systematic effects
Euclid Collaboration, L. W. K. Goh, A. Nouri-Zonoz +301
Euclid is expected to establish new state-of-the-art constraints on extensions beyond the standard LCDM cosmological model by measuring the positions and shapes of billions of gala…
Euclid preparation. XLIII. Measuring detailed galaxy morphologies for Euclid with machine learning
Euclid Collaboration, B. Aussel, S. Kruk +255
The Euclid mission is expected to image millions of galaxies with high resolution, providing an extensive dataset to study galaxy evolution. We investigate the application of deep…
Euclid: Forecasts from the void-lensing cross-correlation
M. Bonici, C. Carbone, S. Davini +129
The Euclid space telescope will survey a large dataset of cosmic voids traced by dense samples of galaxies. In this work we estimate its expected performance when exploiting angula…
The halo bispectrum as a sensitive probe of massive neutrinos and baryon physics
Victoria Yankelevich, Ian G. McCarthy, Juliana Kwan +2
The power spectrum has been a workhorse for cosmological studies of large-scale structure. However, the present-day matter distribution is highly non-Gaussian and significant cosmo…
The reach of next-to-leading-order perturbation theory for the matter bispectrum
Davit Alkhanishvili, Cristiano Porciani, Emiliano Sefusatti +4
We provide a comparison between the matter bispectrum derived with different flavours of perturbation theory at next-to-leading order and measurements from an unprecedentedly large…
preparation: XV. Forecasting cosmological constraints for the and CMB joint analysis
Euclid Collaboration, S. Ilić, N. Aghanim +207
The combination and cross-correlation of the upcoming data with cosmic microwave background (CMB) measurements is a source of great expectation since it will provide the l…
Euclid: constraining dark energy coupled to electromagnetism using astrophysical and laboratory data
M. Martinelli, C. J. A. P. Martins, S. Nesseris +92
In physically realistic scalar-field based dynamical dark energy models (including, e.g., quintessence) one naturally expects the scalar field to couple to the rest of the model's…
Euclid preparation: XI. Mean redshift determination from galaxy redshift probabilities for cosmic shear tomography
Euclid Collaboration, O. Ilbert, S. de la Torre +162
The analysis of weak gravitational lensing in wide-field imaging surveys is considered to be a major cosmological probe of dark energy. Our capacity to constrain the dark energy eq…
Euclid: Forecasts for -cut Point Statistics
P. L. Taylor, T. Kitching, V. F. Cardone +92
Modelling uncertainties at small scales, i.e. high in the power spectrum , due to baryonic feedback, nonlinear structure growth and the fact that galaxies are biased trac…
Euclid: Forecast constraints on the cosmic distance duality relation with complementary external probes
M. Martinelli, C. J. A. P. Martins, S. Nesseris +82
In metric theories of gravity with photon number conservation, the luminosity and angular diameter distances are related via the Etherington relation, also known as the distance-du…
Euclid: The importance of galaxy clustering and weak lensing cross-correlations within the photometric Euclid survey
I. Tutusaus, M. Martinelli, V. F. Cardone +87
The data from the Euclid mission will enable the measurement of the photometric redshifts, angular positions, and weak lensing shapes for over a billion galaxies. This large datase…
Euclid preparation: VII. Forecast validation for Euclid cosmological probes
Euclid Collaboration, A. Blanchard, S. Camera +151
The Euclid space telescope will measure the shapes and redshifts of galaxies to reconstruct the expansion history of the Universe and the growth of cosmic structures. Estimation of…
Cosmological information in the redshift-space bispectrum
Victoria Yankelevich, Cristiano Porciani
We use the Fisher-matrix formalism to investigate whether the galaxy bispectrum in redshift space, , contains additional cosmological information with respect to the power spect…
Towards accurate rescaling of a halo mass function
Victoria Yankelevich, Sergey Pilipenko
We investigate the precision within which a simulated dark matter halo mass function can be rescaled to a different set of cosmological parameters. Our tests show that the accuracy…
Notes on counter-orbiting globular clusters in the Milky Way
Victoria Yankelevich
It is argued that Galactic globular clusters rotating retrograde may originate from prograde globular clusters that change their angular momenturm due to gravitational perturbation…
