Rowan-Robinson, Michael. The Nine Numbers of the Cosmos. Oxford, UK: Oxford University Press, 1999. The density of baryonic matter, anisotropy, rate of expansion, age, microwave background temperature, density of both cold and hot dark matter, cosmological constant, and star formation history altogether make the universe comprehensible.

Sawala, Till, et al. Distinct distributions of elliptical and disk galaxies across the Local Supercluster as a ΛCDM prediction. Nature Astronomy.. August, 2024. We enter this article by University of Helsinki and Durham University, UK astrophysicists including Carlos Frenk for its content and as an example of apparently limitless 21st century Earthuman stellar abilities to explore, instrument, quantify, compute and record by way of data, image, graph, equation, theory any celestial spacescape dimension and temporal dynamic animation.

Galaxies of different types are not equally distributed in the Local Universe. In particular, the supergalactic plane is prominent among the brightest ellipticals, but inconspicuous among the brightest disk galaxies. This striking difference provides a unique test for our understanding of galaxy and structure formation. Here we use the SIBELIUS DARK constrained simulation to confront the predictions of the standard Lambda Cold Dark Matter (ΛCDM) model and standard galaxy formation theory with these observations. We find that SIBELIUS DARK reproduces the spatial distributions of disks and ellipticals and, in particular, the observed excess of massive ellipticals near the supergalactic equator. (Excerpt).

Scharf, Caleb. Is Physical Law an Alien Intelligence? Nautilus. Issue 42, 2016. The Columbia University astrobiologist (search) muses over trending evidence with regard to universal, and multiversal properties which inspire inklings that maybe lively systems equations and systems are actually an intrinsic essence which suffuse our reality. Our interest is to say that such an epochal revolution might imply, akin to Gaian self-regulation on Earth, that animate forces might similarly begin to influence the entire ecosmos.

The universe began to expand at an accelerated rate about 5 billion years ago. This acceleration is conventionally chalked up to dark energy. In fact, one explanation is that the timing has to do with life—an anthropic argument. The dark energy didn’t become significant until enough time had gone by for life to take hold on Earth. For many cosmologists, that means our universe must be part of a vast multiverse where the strength of dark energy varies from place to place. We live in one of the places suitable for life like us. Elsewhere, dark energy is stronger and blows the universe apart too quickly for cosmic structures to form and life to take root. But perhaps there is another reason for the timing coincidence: that dark energy is related to the activities of living things. After all, any very early life in the universe would have already experienced 8 billion years of evolutionary time by the time expansion began to accelerate. It’s a stretch, but maybe there’s something about life itself that affects the cosmos.

This is a 426 page edition by 60 authors which begins with Foundations from matter and energy to the wide array of stellar suns, exoplanetary systems, radiative forces, torques and tides, and more. A next section Comparative Eco-Astrophysics adds evolutionary trajectories for myriad stars, worlds, atmospheres, relative habitability, magnetospheres, and indeed everything under the sun and cosmos.

Schumacher, Jorg and Katepalli Sreenivasan. Colloquium: Unusual Dynamics of Convection in the Sun. Reviews of Modern Physics. 92/041001, 2020. Technical University of Ilmenau, Germany and NYU Tandon School mathematicians (search KS) proceed to analyze, model and describe the active turbulence that composes our home star. We note for its content, and also to record and reflect how incredible it is that we curious creaturely beings are able to achieve such deep and wide cosmic quantifications. One wonders what participant agency and function we peoples are, as yet unawares, carrying out.

The Sun is our nearest star; it is also the most important star that determines life on Earth. A large variety of phenomena observed on the Sun’s surface, with potential impact on Earth, is thought to arise from turbulent convection in Sun’s interior, this being the dominant mode of heat transport within the outer envelope at r≳0.715R⊙. However, convection in the Sun differs in most of its aspects from convection processes known on Earth, certainly those under controlled laboratory conditions, thus seriously challenging existing physical models of convective turbulence and boundary conditions in the Sun. Solar convection is a multiscale-multiphysics phenomenon including the transport of mass, momentum, and heat in the presence of rotation, dynamo action, radiation fluxes, and partial changes in chemical composition.

Stanway, Elizabeth. Applications of Stellar Population Synthesis in the Distant Universe. /galaxies. 8/1, 2020. A University of Warwick astrophysicist provides another example of the 21st century reach and depth of scientific explorations still in thier initial development via Earth and space sensory instrumentation, along with computational methods. By a natural philoSophia going forward, our collaborative humankinder, as able to instantly post, communicate, iterate and advance, seems poised to carry out a self-quantitative description of the whole animate ecosmos.

This review discusses both our current state of understanding of galaxies in the distant Universe, and how that understanding is informed by the stellar population synthesis models we use. Key examples and uncertainties are highlighted, and a holistic approach, in which all possible diagnostic indicators of a stellar population are considered, is advocated. (2)

Steinhardt, Charles and Josh Speagle. A Uniform History for Galaxy Evolution. arXiv:1409.2883. In a paper to appear in the Astrophysical Journal, California Institute of Technology and University of Tokyo researchers report a consensus observation result that developing galaxies of a common mass are remarkably similar to each other at any fixed redshift over a broad range. With such affinities, they are seen to have a predictable temporal course as a “morphological evolution.” But how amazing is it that human persons on a minute orb are yet able at all to quantify, describe, and comprehend such vast reaches. Surely there must be some reason of cosmic import unto discovery that we ought to ask about.

Recent observations indicate a remarkable similarity in the properties of evolving galaxies at fixed mass and redshift, prompting us to consider the possibility that most galaxies may evolve with a common history encompassing star formation, quasar accretion, and eventual quiescence. We quantify this by defining a "synchronization timescale" for galaxies as a function of mass and redshift that characterizes the extent to which different galaxies of a common mass are evolving in the same manner at various cosmic epochs. As a result, we propose a model in which the star-forming "main sequence", analogous quasar behavior, and other observations form a galactic evolution "main sequence", in which star formation occurs earliest, followed by supermassive black hole accretion, and feedback between the two are dominated by deterministic rather than stochastic processes.

Strigari, Louis, et al. A Common Mass Scale for Satellite Galaxies of the Milky Way. Nature. 454/1096, 2008. A collaboration from Irvine, Pasadena, New Haven, Cambridge, MA, and Cambridge, UK finds that some 23 mini-galaxies around the Milky Way, a notable discovery in themselves, in a realm attributed to dark matter, can be seen to take on a correlative hierarchical geometry. One then wonders what kind of universe evolves an Earthkind whom is lately able to gain such consciously perceived quantification.

Strom, Allison. The DNA of Galaxies. carnegiescience.edu/GalaxyDNA. A Carnegie Institution for Science, Washington public lecture by the Carnegie-Princeton astrophysicist which was presented on April 29, 2019. Again the summary invites an engaging view of galactic phenomena.

Like people, each of the billions of galaxies in the universe developed its own unique traits over a complicated lifetime. Until recently, astronomers have only been able to study galaxies closest to the Milky Way in detail, leaving much of the universe's history a mystery. Dr. Strom will show how astronomers are now using the world's largest telescopes to determine the chemical DNA of even very distant galaxies, and how this information is answering key questions about how galaxies like our own formed and evolved.

Taujimoto, Takuji. From Galactic Chemical Evolution to Cosmic Supernova Rates Synchronized with Core-Collapse. arXiv:2211.09160. We cite this entry by a National Astronomical Observatory of Japan researcher as an instance whereby one human member of a collaborative 2020s EartHuman sapience and elibrary resource can be able to learn about and describe, so it seems, any domain, reach, aspect of the whole celestial ecosmos. See also, for example The Basics of Primordial Black Hole Formation by Yoo, Chul-Moon Yoo, Nagoya University, Japan (2211.13512) and A Study of Warm Dark Matter by Bruce Hoeneisen, University of Quito, Ecuador (2211.12574). Such innate capacities of homo to Earthropo individuals requires a radically expansive 2020s definitive appreciation of our phenomenal identity and purpose.

Massive stars perish via one of two fates: core-collapse supernovae, which release synthesized heavy elements, or failed supernovae, thereby forming black holes. In the conventional Galactic chemical evolution (GCE) scheme, larger stars enrich the Galaxy with nucleosynthetic products. Here, we show that the chemicals shaped by thin disk stars meet the predictions by enrichment in the new paradigm of Galactic dynamics that allows stars to migrate from the inner disk.

Torrel, Jean-Claude, et al. Complex Systems in Cosmology: “The Antennae” Case Study. Zhou, Jie, ed. Complex Sciences. Berlin: Springer, 2009. From Volume 2 of these proceedings of the First International Conference on Complex Systems, Shanghai, February 2009, French astrophysicists analyze a collisional impact between two galaxies that appears as two ears of an antenna so as to show that nonlinear phenomena and theories equally apply in this nebulae realm.

Due to its particular shape, “The Antennae” is a well-known complex cosmological dynamical structure. Classical simulations of this phenomenon are based on “top-down” models that required thousands of point-mass particles. We describe an approach for cosmological simulation based on a hierarchical multi-agent system, and evidence is shown that this approach significantly reduces the number of elements needed to simulate “The Antennae” structure. (Abstract, 1887)

A complex system is composed of interacting elements that, as a whole, exhibit properties which cannot be obviously deduced from the ones of the individual elements. Simulating such systems requires the computation of non-linear interactions and, thus, a high computing power bounds to the number of elements. Cosmology is a perfect example of this computing concern; from globular clusters to spiral galaxies, deep space shows a wide variety of complex patterns and behaviors. (1887)

Tyson, Neil de Grasse, et al. Welcome to the Universe: An Astrophysical Tour. Princeton: Princeton University Press,, 2016. The American Museum of Natural History cosmic impresario and senior Princeton astrophysicists Michael Strauss and Richard Gott guide the reader across the spatial cosmic expanse and its dynamic temporal course, with many important stops and topics along the way.

Inspired by the popular introductory astronomy course that Neil de Grasse Tyson, Michael A. Strauss, and J. Richard Gott taught together at Princeton, this book spans from planets, stars, and galaxies to black holes, wormholes, and time travel. Describing the latest discoveries, the informative narrative propels you from our home solar system to the outermost frontiers of space. Why did Pluto lose its planetary status? What are the prospects of intelligent life elsewhere? How did the universe begin? Is our universe alone or part of an infinite multiverse? Answering these and many other questions, the authors share their wonderment about this awesome celestial raiment.
