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

How accurately can we measure the hydrogen 2S->1S transition rate from the cosmological data?
Recent progress in observational cosmology, and especially the forthcoming PLANCK mission data, open new directions in so-called precision cosmology. In this paper we illustrate this statement considering the accuracy of cosmological determination of the

Comment on "Hubble flow variations as a test for inhomogeneous cosmology" [PDF]
Saulder et al [2019, A&A, 622, A83; arXiv:1811.11976] have performed a novel observational test of the local expansion of the Universe for the standard cosmology as compared to an alternative model with differential cosmic expansion.

Abstract There is rising recognition of resource‐use rights of Indigenous Peoples and Local Communities (IPLCs) within wildlife conservation. Historically, sociocultural institutions ensured wildlife sustainability in many IPLC areas. However, the future viability of such institutions is uncertain as IPLCs change in response to external pressures and ...

We present an overview of the Weighing Halos Accurately, Locally, and Efficiently with Supernovae (WHALES) survey, the first to discover and measure Type Ia supernovae (SNe Ia) in and around galaxy superclusters.

The Observational Implications of Loop Quantum Cosmology
In this paper we consider realistic model of inflation embedded in the framework of loop quantum cosmology. Phase of inflation is preceded here by the phase of a quantum bounce.

Abstract Stewardship is broadly defined as ‘universal responsibility of humanity to care for the planet, to ensure that it can continue to provide the essential natural resources for life’. Stewardship practices shape ecosystems, create diverse biocultural landscapes, and can enhance the productivity, availability and health of plants used by ...

The Target-selection Pipeline for the Dark Energy Spectroscopic Instrument
In 2021 May, the Dark Energy Spectroscopic Instrument (DESI) began a 5 yr survey of approximately 50 million total extragalactic and Galactic targets. The primary DESI dark-time targets are emission line galaxies, luminous red galaxies, and quasars.

Scale Invariance in a Perturbed Einstein-de Sitter Cosmology
This paper seeks to check the validity of the "apparent fractal conjecture" (Ribeiro 2001ab: gr-qc/9909093, astro-ph/0104181), which states that the observed power-law behaviour for the average density of large-scale distribution of galaxies arises when ...

Using New Submillimetre Surveys to Identify the Evolutionary Status of High-z Galaxies [PDF]
This paper describes a key submillimetre survey which we are currently conducting to address some of the outstanding questions in cosmology - how, at what epoch and over what period of time did massive galaxies form at high redshift?
