Redshift-dependent galaxy formation efficiency at $z=5-13$ in the FirstLight simulations [PDF]
A&A 689, A244 (2024)Current models of the formation of first galaxies predict low masses and faint objects at extremely high redshifts, z=9-15. However, the first observations of this epoch indicate a higher-than-expected number of bright (sometimes massive) galaxies. Numerical simulations can help to elucidate the mild evolution of the bright end of the UV luminosity ...

Parametric Design of Continuum Robots Using Interlocking Ball Joints
Advanced Intelligent Systems, EarlyView.Herein, a parametric design methodology is introduced for producing a wide variety of modular ball joint‐based continuum robots. It is demonstrate by designing a magnetically actuated continuum robot for cardiac ablations. The methodology is released as an open‐source computer‐assisted design extension that automatically designs continuum robots based ...

The Formation and Evolution of Galaxies
, 1998 Galaxies represent the visible fabric of the Universe and there has been considerable progress recently in both observational and theoretical studies. The underlying goal is to understand the present-day diversity of galaxy forms, masses and luminosities.

The role of black holes in galaxy formation and evolution [PDF]
Nature, 2009 Virtually all massive galaxies, including our own, host central black holes ranging in mass from millions to billions of solar masses. The growth of these black holes releases vast amounts of energy that powers quasars and other weaker active galactic nuclei.

The Astrophysical Journal Letters, 2023 We present JWST Mid-InfraRed Instrument/Medium-Resolution Spectrometer (MIRI/MRS) observations of an infrared luminous disk galaxy, FLS1, at z ∼ 0.54. With a lookback time of 5 Gyr, FLS1 is chronologically at the midpoint between the peak epoch of star ...

Incorporating Morphological Types into Semi-analytic Schemes for Galaxy Formation [PDF]
arXiv, 1995 We test the hypothesis that elliptical galaxies are formed by violent mergers in a universe with hierarchical structure formation. Within the framework of a semi-analytic scheme for galaxy formation, we predict the distribution of morphological types with redshift and compare the colours of elliptical galaxies in different environments.

And the winner is: galaxy mass
, 2011 The environment is known to affect the formation and evolution of galaxies considerably best visible through the well-known morphology-density relationship.

Annals of Neurology, EarlyView.Artificial intelligence (AI) applications are finding use in real‐world neurological settings. Whereas part 1 of this 3‐part review series focused on the birth of AI and its foundational principles, this part 2 review shifts gears to explore more practical aspects of neurological care.

The Role of Interactions and Mergers [PDF]
arXiv, 1998 Galaxy evolution depends strongly on the environment. Dynamical interactions and subsequent evolution make galaxies more concentrated, with higher surface densities, and also trigger star-formation, which consumes the available cold gas. Already at z=0, a large variety of galaxy types are observed, with different evolution stages, from the unevolved ...

The origin of pseudobulges in cosmological simulations of galaxy formation
, 2012 More than half of nearby disc galaxies have pseudobulges instead of classical bulges that are though to be end-products of galaxy mergers. Pseudobulges are presumed to develop overtime as a result of secular evolution of galaxy discs.
