Detecting the 21 cm Signal from the Cosmic Dark Ages
The Astrophysical JournalThe cosmic “dark ages” is the period between the last scattering of the cosmic microwave background and the appearance of the first luminous sources, spanning redshifts 1100 ≳ z ≳ 30.

Statefinder diagnostic for cosmology with the abnormally weighting energy hypothesis
, 2007 In this paper, we apply the statefinder diagnostic to the cosmology with the Abnormally Weighting Energy hypothesis (AWE cosmology), in which dark energy in the observational (ordinary matter) frame results from the violation of weak equivalence ...

Science Education, EarlyView.ABSTRACT In this article I explore the case of the Mariana dam disaster in 2015 in Brazil seeking to contribute to reflections about the role of chemistry and chemistry education in environmental injustices. Drawing on stories about this disaster shared in the Dead River Podcast (2024), on wider literature and on other cases of environmental injustices

The ΛCDM-NG Cosmological Model: A Possible Resolution of the Hubble Tension
The Astrophysical JournalWe offer a cosmological model based on conventional general relativity (no speculative physics) that may resolve the Hubble tension. A reanalysis of the foundation of the Lambda-CDM model shows that general relativity alone does not specify what fraction

COSMOLOGICAL OBSERVATIONS AND BACKREACTION [PDF]
, 2014 Since the very beginning the Friedmann-Robertson-Walker metric has played one of the most important roles in developing cosmology. The underlying assumptions of maximal symmetry have simplified our general view of the Universe but recent developments in observational cosmology, like the discovery of cosmic acceleration, have demonstrated that a more ...

Integrating multimodal data and machine learning for entrepreneurship research
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary Extant research in neuroscience suggests that human perception is multimodal in nature—we model the world integrating diverse data sources such as sound, images, taste, and smell. Working in a dynamic environment, entrepreneurs are expected to draw on multimodal inputs in their decision making.

Reheating via gravitational particle production in simple models of quintessence or $\Lambda$CDM inflation [PDF]
, 2017 We have tested some simple $\Lambda$CDM (the same test is also valid for quintessence) inflation models, imposing that they match with the recent observational data provided by the BICEP and Planck's team and leading to a reheating temperature, which is ...

New Directions for Teaching and Learning, EarlyView.ABSTRACT This chapter simultaneously tells a story and examines the process of storytelling as it shares ideas about the decolonization of drama, theatre, and performance provoked by participating in a Disrupting interview process that included an individual interview and a land‐based medicine walk.

Journal of the Royal Anthropological Institute, EarlyView.In this article, I delve into the field diary of Ma Changshou – a major Chinese ethnohistorian and social anthropologist active between the 1930s and 1960s – to show how his journeys through Liangshan, a mountainous land in Southwest China inhabited by the Nuosu‐Yi, led to a new kind of anthropological knowledge.
