Evidence for Dark Energy Driven by Star Formation: Information Dark Energy? [PDF]

open access: yesEntropy
Evidence is presented for dark energy resulting directly from star formation. A survey of stellar mass density measurements, SMD(a), as a function of universe scale size a, was found to be described by a simple CPL w0 − wa parameterisation that was in ...

Information Dark Energy Can Resolve the Hubble Tension and Is Falsifiable by Experiment [PDF]

open access: yesEntropy, 2022
We consider the role information energy can play as a source of dark energy. Firstly, we note that if stars and structure had not formed in the universe, elemental bits of information describing the attributes of particles would have exhibited properties

The dark matter and dark energy [PDF]

open access: yesSHS Web of Conferences, 2023
The dark matter and dark energy are one of the biggest challenges facing contemporary physics and astronomy. Dark energy and dark matter play an important role the universe.

Combining outlier analysis algorithms to identify new physics at the LHC

open access: yesJournal of High Energy Physics, 2021
The lack of evidence for new physics at the Large Hadron Collider so far has prompted the development of model-independent search techniques. In this study, we compare the anomaly scores of a variety of anomaly detection techniques: an isolation forest ...

290 metagenome-assembled genomes from the Mediterranean Sea: a resource for marine microbiology [PDF]

open access: yesPeerJ, 2017
The Tara Oceans Expedition has provided large, publicly-accessible microbial metagenomic datasets from a circumnavigation of the globe. Utilizing several size fractions from the samples originating in the Mediterranean Sea, we have used current assembly ...

Constrains on the electric charges of the binary black holes with GWTC-1 events

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Testing black hole’s charged property is a fascinating topic in modified gravity and black hole astrophysics. In the first Gravitational-Wave Transient Catalog (GWTC-1), ten binary black hole merger events have been formally reported, and these ...

Using Host Galaxy Photometric Redshifts to Improve Cosmological Constraints with Type Ia Supernovae in the LSST Era

open access: yesThe Astrophysical Journal, 2023
We perform a rigorous cosmology analysis on simulated Type Ia supernovae (SNe Ia) and evaluate the improvement from including photometric host galaxy redshifts compared to using only the “ z _spec ” subset with spectroscopic redshifts from the host or SN.

Characterizing the Sample Selection for Supernova Cosmology

open access: yesThe Open Journal of Astrophysics, 2021
Type Ia supernovae (SNe Ia) are used as distance indicators to infer the cosmological parameters that specify the expansion history of the universe. Parameter inference depends on the criteria by which the analysis SN sample is selected.

A comparison of optimisation algorithms for high-dimensional particle and astrophysics applications

open access: yesJournal of High Energy Physics, 2021
Optimisation problems are ubiquitous in particle and astrophysics, and involve locating the optimum of a complicated function of many parameters that may be computationally expensive to evaluate.

On dark matter and dark energy

open access: yesЛитьë и металлургия, 2020
The dark matter hypothesis was created to explain the reason for the preservation of stellar clusters from dispersion. The weak point of this hypothesis is the great age of space, which is 13.8 billion years.
