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.

The Truncated Lognormal Distribution as a Luminosity Function for SWIFT-BAT Gamma-Ray Bursts

Galaxies, 2016
The determination of the luminosity function (LF) in Gamma ray bursts (GRBs) depends on the adopted cosmology, each one characterized by its corresponding luminosity distance.

Towards an Observational Appraisal of String Cosmology

, 2011
We review the current observational status of string cosmology when confronted with experimental datasets. We begin by defining common observational parameters and discuss how they are determined for a given model.

The Apparent Fractal Conjecture [PDF]

, 1999
This short communication advances the hypothesis that the observed fractal structure of large-scale distribution of galaxies is due to a geometrical effect, which arises when observational quantities relevant for the characterization of a cosmological ...

From the manager's point of view: work intensification, posthuman ethnography, and healthcare in England Du point de vue des managers : intensification du travail, ethnographie post‐humaine et soins de santé en Angleterre

Journal of the Royal Anthropological Institute, EarlyView.
Drawing on fieldwork conducted in a hospital in Greater Manchester, England in 2016–17, we describe how a set of national health priorities were translated into work for hospital managers and clinicians during a period of significant organizational pressure.

Revisiting the Hubble Constant, Sound Horizon, and Cosmography from Late-time Universe Observations

The Astrophysical Journal
The Hubble tension has become one of the central problems in cosmology. In this work, we determine the Hubble constant H _0 and sound horizon r _d by using the combination of baryon acoustic oscillations (BAOs) from DESI surveys, time-delay lensed ...

Observing the dark sector

, 2019
Despite the observational success of the standard model of cosmology, present-day observations do not tightly constrain the nature of dark matter and dark energy and modifications to the theory of general relativity.

Stringy Effects During Inflation and Reheating [PDF]

, 2005
We consider inflationary cosmology in the context of string compactifications with multiple throats. In scenarios where the warping differs significantly between throats, string and Kaluza-Klein physics can generate potentially observable corrections to ...

World Heritage Status and Farmers’ Income: Evidence From a Regression Discontinuity Design in Colombia

Agricultural Economics, EarlyView.
ABSTRACT The core of Colombia's coffee growing region was designated as a World Heritage (WH) site in 2011, making a distinction between “the core” of the region and “the periphery.” However, the coffee cultural heritage does not abruptly stop at the WH boundary but it exists inside and outside the boundary.
