Cosmic Evolution of Stellar-mass Black Hole Merger Rate in Active Galactic Nuclei [PDF]

open access: yesAstrophysical Journal, 2020
Binary black hole mergers encode information about their environment and the astrophysical processes that led to their formation. Measuring the redshift dependence of their merger rate will help probe the formation and evolution of galaxies and the ...

‘Creation out of nothing’ – A problematic assumption: biblical, metaphysical and scientific perspectives

open access: yesHTS Teologiese Studies/Theological Studies, 2021
Science, technology, commerce and consumerism have set humankind on a trajectory towards a catastrophe of inestimable proportions. To respond appropriately to this danger, theology must replace obsolete contextualisations of its message with currently ...

Cosmic evolution in f(T) gravity theory [PDF]

open access: yesModern Physics Letters A, 2020
The paper deals with cosmology in modified [Formula: see text] gravity theory. With some phenomenological choices for the function [Formula: see text] it is possible to have cosmological solutions describing different phases of the evolution of the ...

Energy Budgets of Evolving Nations and Their Growing Cities

open access: yesEnergies, 2022
A new way is proposed to thermodynamically gauge the evolving complexity of nation-states and their growing cities. Energy rate density is a useful metric to track the evolution of energy budgets, which help facilitate how well or badly human society ...

Cosmic evolution of dark energy in a generalized Rastall gravity [PDF]

open access: yes, 2020
In this work, we propose a scheme for cosmic evolution in a generalized Rastall gravity. In our approach, the role of dark energy is taken by the non-conserved sector of the stress energy–momentum tensor.

The Cosmic Merger Rate Density Evolution of Compact Binaries Formed in Young Star Clusters and in Isolated Binaries [PDF]

open access: yesAstrophysical Journal, 2020
Next generation ground-based gravitational-wave detectors will observe binary black hole (BBH) mergers up to redshift , probing the evolution of compact binary (CB) mergers across cosmic time.

The Cosmic Evolution Early Release Science Survey (CEERS) [PDF]

open access: yesAstrophysical Journal Letters
We present the Cosmic Evolution Early Release Science (CEERS) Survey, a 77.2 hr Director’s Discretionary Early Release Science Program. CEERS demonstrates, tests, and validates efficient extragalactic surveys using coordinated, overlapping parallel ...

The Evolution of the Baryons Associated with Galaxies Averaged over Cosmic Time and Space [PDF]

open access: yesAstrophysical Journal, 2020
We combine the recent determination of the evolution of the cosmic density of molecular gas (H2) using deep, volumetric surveys, with previous estimates of the cosmic density of stellar mass, star formation rate and atomic gas (H i), to constrain the ...

The Cosmic Evolution Survey (COSMOS): Overview [PDF]

open access: yes, 2006
The Cosmic Evolution Survey (COSMOS) is designed to probe the correlated evolution of galaxies, star formation, active galactic nuclei (AGNs), and dark matter (DM) with large-scale structure (LSS) over the redshift range z > 0.5-6.

First results from the TNG50 simulation: the evolution of stellar and gaseous discs across cosmic time [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
We present a new cosmological, magnetohydrodynamical simulation for galaxy formation: TNG50, the third and final instalment of the IllustrisTNG project. TNG50 evolves 2 × 21603 dark matter particles and gas cells in a volume 50 comoving Mpc across.
