Abstract The exploration of the surrounding world and the universe is an important theme in the legacy of humankind. The detection of gravitational waves is adding a new dimension to this grand effort. What are the funda...

We investigate five different models for the dark matter (DM) halo bias, that is, the ratio of the fluctuations of mass tracers to those of the underlying mass, by comparing their cosmological evolution using optical qua...

Aims. We investigate whether viscous cold dark matter (vCDM) in a Λ-dominated Friedmann-Lemaître-Robertson-Walker (FLRW) universe can alleviate the Hubble tension, while satisfying thermodynamic constraints. Here, we e...

Precise measurements of Type Ia supernovae (SNe Ia) at low redshifts ( z ) serve as one of the most viable keys to unlocking our understanding of cosmic expansion, isotropy, and growth of structure. The Dark Energy Bedr...

Any inconsistent theory whose underlying logic is classical encompasses all the sentences of its own language. As it denies everything it asserts, it is useless for explaining or predicting anything. Nevertheless, paraco...

A partir de la categoría analítica de ‘universo superpoblado’ propuesta por Florencia Tola (2012) para la cosmología de los indígenas qom del Gran Chaco, es mi objetivo dar cuenta de su operatividad para el caso ...

We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave background (CMB) data and a recent reanalysis ...

Este artículo aborda dos de los conceptos más frecuentemente usados en la astronomía cultural: cosmovisión y cosmología. A pesar de su importancia hay pocos trabajos (Iwaniszewski 2009a; 2009b; 2010; 2011) que desde...

Con Giordano Bruno (1548-1600) asistimos a la recuperación de doctrinas neoplatónicas y herméticas que conducen a una comprensión animista y dinámica de la naturaleza, así como a una exaltación del hombre en tanto...

Strong gravitational lenses serve as powerful probes for cosmology and the mass distribution of galaxies. However, identifying these rare systems is often hindered by inaccurate localization and confusion with morphologi...

The study deals with pilgrimages to Esquipulas, Guatemala, and patterns of miracle in terms of their perception by the pilgrims reaching this prominent religious hub of Central America. Two key pilgrimage discourses are ...

Properties of massive galaxy clusters, such as mass abundance and concentration, are sensitive to cosmology, making cluster statistics a powerful tool for cosmological studies. However, favoring a more simplified, spheri...

En el marco del Convenio entre el CONICET, el CEHP-DADU-UNDAV y el Ministerio de Cultura de Santa Fe (para la puesta en valor del archivo personal de Fernando Birri), se inició una reflexión en torno a las obras emblem...

Family physicians have developed a holistic approach to patients’ care which can facilitate a mutual understanding of different Traditional and Complementary Medicine (T&CM) practices. This analytical paper considers t...

Based on ethnographic research carried out in Codó, in the interior of Maranhão, this article seeks to answer how religious entities relate to the city. To achieve this goal, the field of Afro-Brazilian religion studie...

The Q&U Bolometric Interferometer for Cosmology (QL’BIC) is the first bolometric interferometer designed to measure the primordial B-mode polarization of the Cosmic Microwave Background (CMB). Bolometric interferometry...

We present a new cosmological test using the distribution of galaxies around cosmic voids without assuming a fiducial cosmology. The test is based on a physical model for the void-galaxy cross-correlation function projec...

Se propone un estudio de la visión toba del cielo: los objetos celestes, asterismos y aquellos fenómenos que desde la óptica nativa se relacionan significativamente con el firmamento. Esta interpretación de lo celest...

Observations support the idea that supermassive black holes (SMBHs) power the emission at the centre of active galaxies. However, contrary to stellar-mass BHs, there is a poor understanding of their origin and physical f...

Abstract In this study, we explore the reheating phase that follows tachyon inflation within the framework of holographic induced gravity (H-IG). Analytical relations for the reheating temperature $$T_{re}$$ T re and the...

The Q and U Bolometric Interferometer for Cosmology (QUBIC) is a ground-based experiment that aims to detect B-mode polarization anisotropies [1] in the CMB at angular scales around the â.,"≃100 recombination peak. Sy...

This paper presents a resume of results obtained recently in the context of cosmology. We see how systems with escalating fields that can resolve the riddle of dark matter also can have a non linear comportment of the s...
