Searching for signatures of inflationary massive fields in DESI Imaging data and Stage-V galaxy surveys
Walter Riquelme, Santiago Avila, Lucas Pinol +2
We investigate the cosmological imprints of massive fields during inflation through primordial non-Gaussianity (PNG). When these fields are sufficiently light, they produce a signa…
Constraints on Dynamical Dark Energy from Multiple Probes in the Full Dark Energy Survey
DES Collaboration, T. M. C. Abbott, M. Adamow +166
We present results on dark energy evolution, assuming a time-dependent equation of state , from growth and geometric probes using the full six-year Dark Energy S…
Dark Energy Survey Year 6 Results: Cosmological Constraints from Galaxy Clustering and Weak Lensing
DES Collaboration, T. M. C. Abbott, M. Adamow +169
We present cosmology results combining galaxy clustering and weak gravitational lensing measured in the full six years (Y6) of observations by the Dark Energy Survey (DES) covering…
Dark Energy Survey Year 6 Results: MagLim++ Lens Sample Selection and Measurements of Galaxy Clustering
N. Weaverdyck, M. Rodríguez-Monroy, J. Elvin-Poole +85
Galaxy clustering is a sensitive probe of the expansion history and growth of structure of the universe, and key degeneracies can be broken by combining these data with measurement…
Imprints of Large-Scale Structures in the Anisotropies of the Cosmological Gravitational Wave Background
Rafael Bravo, Walter Riquelme
We compute the cross-correlation between the anisotropies of the cosmological gravitational wave background (CGWB) and the galaxy density contrast. We show that the cross-correlati…
Primordial non-Gaussianity with Angular correlation function: Integral constraint and validation for DES
Walter Riquelme, Santiago Avila, Juan Garcia-Bellido +17
Local primordial non-Gaussianity (PNG) is a promising observable of the underlying physics of inflation, characterised by . We present the methodology to meas…
Dark Energy Survey Year 3 Results: Galaxy Sample for BAO Measurement
A. Carnero Rosell, M. Rodriguez-Monroy, M. Crocce +106
In this paper we present and validate the galaxy sample used for the analysis of the Baryon Acoustic Oscillation signal (BAO) in the Dark Energy Survey (DES) Y3 data. The definitio…
Landscape tomography through primordial non-Gaussianity
Xingang Chen, Gonzalo A. Palma, Walter Riquelme +2
In this paper, we show how the structure of the landscape potential of the primordial Universe may be probed through the properties of the primordial density perturbations responsi…
Axion excursions of the landscape during inflation
Gonzalo A. Palma, Walter Riquelme
Because of their quantum fluctuations, axion fields had a chance to experience field excursions traversing many minima of their potentials during inflation. We study this situation…
Scale invariance of the primordial tensor power spectrum
Gonzalo A. Palma, Bastian Pradenas, Walter Riquelme +1
Future cosmic microwave background polarization experiments will search for evidence of primordial tensor modes at large angular scales, in the multipole range $4 \leq \ell \leq 50…
