A robust cosmic standard ruler from the cross-correlations of galaxies and dark sirens
João Ferri, Ian L. Tashiro, L. Raul Abramo +3
Observations of gravitational waves (GWs) from dark sirens allow us to infer their locations and distances. Galaxies, on the other hand, have precise angular positions but no direc…
Cluster profiles from beyond-the-QE CMB lensing mass maps
Sayan Saha, Louis Legrand, Julien Carron
Clusters of galaxies, being the largest collapsed structures in the universe, offer valuable insights into the nature of cosmic evolution. Precise calibration of the mass of cluste…
Constraining Horndeski theory with gravitational waves from coalescing binaries
Miguel Quartin, Shinji Tsujikawa, Luca Amendola +1
In the broad subclass of Horndeski theories with a luminal speed of gravitational waves, we derive gravitational waveforms emitted from a compact binary by considering the wave pro…
Early dark energy constraints with late-time expansion marginalization
João Rebouças, Jonathan Gordon, Diogo H. F. de Souza +5
Early dark energy (EDE) is an extension to the CDM model, proposed to reduce the tension between the measurements of the Hubble constant from the cosmic microwave backgrou…
Dark Energy Survey Year 3 Results: Galaxy mock catalogs for BAO analysis
I. Ferrero, M. Crocce, I. Tutusaus +83
The calibration and validation of scientific analysis in simulations is a fundamental tool to ensure unbiased and robust results in observational cosmology. In particular, mock gal…
Mitigating baryonic effects with a theoretical error covariance
Maria G. Moreira, Felipe Andrade-Oliveira, Xiao Fang +5
One of the primary sources of uncertainties in modeling the cosmic-shear power spectrum on small scales is the effect of baryonic physics. Accurate cosmology for Stage-IV surveys r…
Cosmological Constraints from Multiple Probes in the Dark Energy Survey
DES Collaboration, T. M. C. Abbott, A. Alarcon +166
The combination of multiple observational probes has long been advocated as a powerful technique to constrain cosmological parameters, in particular dark energy. The Dark Energy Su…
Dark Energy Survey Year 1 Results: Constraints on Extended Cosmological Models from Galaxy Clustering and Weak Lensing
DES Collaboration, T. M. C. Abbott, F. B. Abdalla +112
We present constraints on extensions of the minimal cosmological models dominated by dark matter and dark energy, CDM and CDM, by using a combined analysis of galaxy clusteri…
Dark Energy Survey Year 1 Results: Measurement of the Galaxy Angular Power Spectrum
H. Camacho, N. Kokron, F. Andrade-Oliveira +73
We use data from the first-year (Y1) observations of the DES collaboration to measure the galaxy angular power spectrum (APS), and search for its BAO feature using a template-fitti…
BAO from angular clustering: optimization and mitigation of theoretical systematics
K. C. Chan, M. Crocce, A. J. Ross +58
We study the methodology and potential theoretical systematics of measuring Baryon Acoustic Oscillations (BAO) using the angular correlation functions in tomographic bins. We calib…
Dark Energy Survey Year 1 Results: galaxy mock catalogues for BAO
S. Avila, M. Crocce, A. J. Ross +51
Mock catalogues are a crucial tool in the analysis of galaxy surveys data, both for the accurate computation of covariance matrices, and for the optimisation of analysis methodolog…
Dark Energy Survey Year 1 Results: Galaxy Sample for BAO Measurement
M. Crocce, A. J. Ross, I. Sevilla-Noarbe +84
We define and characterise a sample of 1.3 million galaxies extracted from the first year of Dark Energy Survey data, optimised to measure Baryon Acoustic Oscillations in the prese…
Dark Energy Survey Year 1 Results: Measurement of the Baryon Acoustic Oscillation scale in the distribution of galaxies to redshift 1
The Dark Energy Survey Collaboration, T. M. C. Abbott, F. B. Abdalla +109
We present angular diameter distance measurements obtained by locating the BAO scale in the distribution of galaxies selected from the first year of Dark Energy Survey data. We con…
Dark Energy Survey Year 1 Results: Cosmological Constraints from Galaxy Clustering and Weak Lensing
DES Collaboration, T. M. C. Abbott, F. B. Abdalla +197
We present cosmological results from a combined analysis of galaxy clustering and weak gravitational lensing, using 1321 deg of imaging data from the first year of the D…
Theoretical predictions for dark matter detection in dwarf irregular galaxies with gamma rays
V. Gammaldi, E. V. Karukes, P. Salucci
We investigate dwarf irregular(dIrr) galaxies as a new category of targets for indirect Dark Matter(DM) searches with gamma-rays. In the framework of point-like analysis, dwarf sph…
Combined analysis of galaxy cluster number count, thermal Sunyaev-Zel'dovich power spectrum, and bispectrum
G. Hurier, F. Lacasa
The Sunyaev-Zel'dovich (SZ) effect is a powerful probe of the evolution of structures in the universe, and is thus highly sensitive to cosmological parameters and , thou…
Spherical Cows in Dark Matter Indirect Detection
Nicolás Bernal, Lina Necib, Tracy R. Slatyer
Dark matter (DM) halos have long been known to be triaxial, but in studies of possible annihilation and decay signals they are often treated as approximately spherical. In this wor…
Testing the lognormality of the galaxy and weak lensing convergence distributions from Dark Energy Survey maps
L. Clerkin, D. Kirk, M. Manera +57
It is well known that the probability distribution function (PDF) of galaxy density contrast is approximately lognormal; whether the PDF of mass fluctuations derived from weak lens…
Cosmic Voids and Void Lensing in the Dark Energy Survey Science Verification Data
C. Sánchez, J. Clampitt, A. Kovacs +69
Galaxies and their dark matter halos populate a complicated filamentary network around large, nearly empty regions known as cosmic voids. Cosmic voids are usually identified in spe…
