Gravitational waves from dark matter isocurvature
Guillem Domènech, Samuel Passaglia, Sébastien Renaux-Petel
The primordial fluctuations on large scales are adiabatic, but on smaller scales this need not be the case. Here we derive the general analytical framework to compute the stochasti…
Euclid: Covariance of weak lensing pseudo- estimates. Calculation, comparison to simulations, and dependence on survey geometry
R. E. Upham, M. L. Brown, L. Whittaker +102
An accurate covariance matrix is essential for obtaining reliable cosmological results when using a Gaussian likelihood. In this paper we study the covariance of pseudo- es…
Gravitational background from dynamical binaries and detectability with 2G detectors
Carole Périgois, Filippo Santoliquido, Yann Bouffanais +5
We study the impact of young clusters on the gravitational wave background from compact binary coalescence. We simulate a catalog of sources from population I/II isolated binary st…
Were recently reported MHz events planet mass primordial black hole mergers?
Guillem Domènech
A bulk acoustic wave cavity as high frequency gravitational wave antenna has recently detected two rare events at MHz. Assuming that the detected events are due to gravitation…
Constraints on the cosmic expansion history from GWTC-3
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1676
We use 47 gravitational-wave sources from the Third LIGO-Virgo-KAGRA Gravitational-Wave Transient Catalog (GWTC-3) to estimate the Hubble parameter , including its current va…
In-flight polarization angle calibration for LiteBIRD: blind challenge and cosmological implications
Nicoletta Krachmalnicoff, Tomotake Matsumura, Elena de la Hoz +67
We present a demonstration of the in-flight polarization angle calibration for the JAXA/ISAS second strategic large class mission, LiteBIRD, and estimate its impact on the measurem…
The RayGalGroupSims cosmological simulation suite for the study of relativistic effects: an application to lensing-matter clustering statistics
Y. Rasera, M-A. Breton, P-S. Corasaniti +8
General Relativistic effects on the clustering of matter in the universe provide a sensitive probe of cosmology and gravity theories that can be tested with the upcoming generation…
Signatures of Primordial Gravitational Waves on the Large-Scale Structure of the Universe
Pritha Bari, Angelo Ricciardone, Nicola Bartolo +2
We study the generation and evolution of second-order energy-density perturbations arising from primordial gravitational waves. Such "tensor-induced scalar modes" approximately evo…
Breaking the Single Clock Symmetry: measuring single-field inflation non-Gaussian features
Daniele Bertacca, Raul Jimenez, Sabino Matarrese +1
The Universe is not just cold dark matter and dark energy, it also contains baryons, radiation and neutrinos. The presence of these components, beyond the pressure-less cold dark m…
Expansion history-dependent oscillations in the scalar-induced gravitational wave background
Lukas T. Witkowski, Guillem Domènech, Jacopo Fumagalli +1
Oscillations in the frequency profile of the scalar-induced contribution to the stochastic gravitational wave background are a characteristic signal for small-scale features during…
Leverage on small-scale primordial non-Gaussianity through cross-correlations between CMB -mode and -distortion anisotropies
Mathieu Remazeilles, Andrea Ravenni, Jens Chluba
Multi-field inflation models and non-Bunch-Davies vacuum initial conditions both predict sizeable non-Gaussian primordial perturbations and anisotropic -type spectral distortion…
Euclid: Forecast constraints on consistency tests of the CDM model
S. Nesseris, D. Sapone, M. Martinelli +112
The standard cosmological model is based on the fundamental assumptions of a spatially homogeneous and isotropic universe on large scales. An observational detection of a violation…
KiDS & Euclid: Cosmological implications of a pseudo angular power spectrum analysis of KiDS-1000 cosmic shear tomography
A. Loureiro, L. Whittaker, A. Spurio Mancini +111
We present a tomographic weak lensing analysis of the Kilo Degree Survey Data Release 4 (KiDS-1000), using a new pseudo angular power spectrum estimator (pseudo-) under d…
Euclid preparation: XIX. Impact of magnification on photometric galaxy clustering
F. Lepori, I. Tutusaus, C. Viglione +183
We investigate the importance of lensing magnification for estimates of galaxy clustering and its cross-correlation with shear for the photometric sample of Euclid. Using updated s…
The paradigm of warm quintessential inflation and spontaneous baryogenesis
Soumen Basak, Sukannya Bhattacharya, Mayukh R. Gangopadhyay +3
In this paper, we consider a scenario of spontaneous baryogenesis in a framework of warm quintessential inflation where the residual inflaton field, left out after warm inflation,…
Search for subsolar-mass binaries in the first half of Advanced LIGO and Virgo's third observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1634
We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 and 1.0 in Advanced LIGO and Advanced Virgo dat…
Clustering of Gravitational Wave and Supernovae events: a multitracer analysis in Luminosity Distance Space
Sarah Libanore, Maria Celeste Artale, Dionysios Karagiannis +5
We study the clustering of Gravitational Wave (GW) merger events and Supernovae IA (SN), as cosmic tracers in Luminosity Distance Space. We modify the publicly available CAMB code…
