Testing Scale-Dependent Suppression of Structure Growth in the Linear Regime

Fernanda Oliveira, Miguel A. Sabogal, Felipe Avila +2

We investigate recent reports of a suppression in the growth rate of cosmic structures inferred from analyses of the dataset. To address this issue, we explore the hyp…

Viability of general relativity and modified gravity cosmologies using high-redshift cosmic probes

Fernanda Oliveira, Bruno Ribeiro, Wiliam S. Hipólito-Ricaldi +2

Several models based on General Relativity and Modified Gravity aim to reproduce the observed universe with precision comparable to the flat-CDM cosmological model. In this stu…

Probing the Cosmic Distance Duality Relation via Non-Parametric Reconstruction for High Redshifts

Felipe Avila, Fernanda Oliveira, Camila Franco +4

We test the validity of the cosmic distance duality relation (CDDR) by combining angular diameter distance and luminosity distance measurements from recent cosmological observation…

Is CDM a good model for the clumpy Universe?

Fernanda Oliveira, Felipe Avila, Camila Franco +1

The DESI collaboration just obtained a set of precise BAO measurements, that combined with CMB and SNIa datasets show that the CDM model is preferred over CDM, at mo…

The SPT-Deep Cluster Catalog: Sunyaev-Zel'dovich Selected Clusters from Combined SPT-3G and SPTpol Measurements over 100 Square Degrees

K. Kornoelje, L. E. Bleem, E. S. Rykoff +191

We present a catalog of 500 galaxy cluster candidates in the SPT-Deep field: a 100 deg field that combines data from the SPT-3G and SPTpol surveys to reach noise levels of 3.0,…
