Cross-correlation Techniques to Mitigate the Interloper Contamination for Line Intensity Mapping Experiments

The Astrophysical Journal
Line intensity mapping (LIM) serves as a potent probe in astrophysics, relying on the statistical analysis of integrated spectral line emissions originating from distant star-forming galaxies.

Data Analysis for Precision 21 cm Cosmology [PDF]

Publications of the Astronomical Society of the Pacific, 2019
The redshifted 21 cm line is an emerging tool in cosmology, in principle permitting three-dimensional surveys of our universe that reach unprecedentedly large volumes, previously inaccessible length scales, and hitherto unexplored epochs of our cosmic ...

Knowledge acquisition in science and the blurred boundary between perception and cognition

British Educational Research Journal, EarlyView.
Abstract This paper provides a critical and detailed study of what researchers in the fields of contemporary cognition and neuroscience have revealed about the blurred boundary between perception and cognition. We set out the arguments with a view to what researchers and teachers should now consider regarding the subtleties of their interrelationship ...

The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

No thanks: How an ideology of sharing, not reciprocating, ensures abundance in the forests of south‐eastern Cameroon

People and Nature, EarlyView.
Abstract Reciprocity and relationality are themes which frequently emerge with respect to human–nature associations in Indigenous groups around the world. But many hunter‐gatherers have been shown to reject systems of reciprocity, instead favouring unconditional sharing both between each other and their environment through egalitarian social structures.

Reciprocal contributions: Indigenous perspectives and voices on marine‐coastal experiences in the channels of northern Patagonia, Chile

People and Nature, EarlyView.
Abstract The recovery of marine ecosystems in areas heavily impacted by fishing and environmental exploitation depends, to some extent, on the sustainable management of resources and should be complemented by cultural traditions, practices and scientific knowledge.

Indigenous knowledge‐bridging to support ecological stewardship in Canada and Tanzania

People and Nature, EarlyView.
Abstract Indigenous peoples worldwide assert their cultural and political governance through ecological stewardship and traditional land use. With the rapid degradation of ecosystems globally, there is a growing need to strengthen the role of Indigenous knowledge systems and values in environmental stewardship.

Cosmic Chronometers, Pantheon+ Supernovae, and Quasars Favor Coasting Cosmologies over the Flat ΛCDM Model

The Astrophysical Journal
We test and compare coasting cosmological models with curvature parameters $k=\left\{-1,0,+1\right\}$ in ${H}_{0}^{2}{c}^{-2}$ units and the flat ΛCDM model by fitting them to cosmic chronometers (CCs), the Pantheon+ sample of Type Ia supernovae (SNe ...

Effects of Type Ia Supernovae Absolute Magnitude Priors on the Hubble Constant Value

The Astrophysical Journal Letters
We systematically explore the influence of the prior of the peak absolute magnitude ( M ) of Type Ia supernovae (SNe Ia) on the measurement of the Hubble constant ( H _0 ) from SNe Ia observations.

Cosmological Dynamics of Interacting Dark Energy and Dark Matter in f(Q)$f(Q)$ Gravity

Fortschritte der Physik, EarlyView.
Abstract In this work, the behavior of interacting dark energy (DE) and dark matter (DM) within a model of f(Q)$f(Q)$ gravity is explored, employing the standard framework of dynamical system analysis. The power‐law f(Q)$f(Q)$ model is considered, incorporating two different forms of interacting DE and DM: 3αHρm$3\alpha H\rho _m$ and α3HρmρDE$\frac ...
