GalaxiesObservations provided by the Hubble Space Telescope (HST) and James Webb Space Telescope (JWST) have revealed a surprising abundance of galaxies at the “cosmic dawn” epoch, z>7. Some of them are found even in a more distant universe at z ≃ 14–16. Most of

, 2013 Galaxy morphology is a product of how galaxies formed, how they interacted with their environment, how they were influenced by internal perturbations, AGN, and dark matter, and of their varied star formation histories. This article reviews the phenomenology of galaxy morphology and classification with a view to delineating as many types as possible and

Out There No One Has a Right to Die
Bioethics, EarlyView.ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...

Study on the Gamma-Ray Radiation Properties of High-Redshift Blazars at z > 2.5
UniverseThe high-redshift blazars are important cosmological probes for exploring the early universe and unraveling the fundamental emission processes and the structure of the active galactic nuclei.

Computers and chess masters: The role of AI in transforming elite human performance
British Journal of Psychology, EarlyView.Abstract Advances in Artificial Intelligence (AI) have made significant strides in recent years, often supplementing rather than replacing human performance. The extent of their assistance at the highest levels of human performance remains unclear. We analyse over 11.6 million decisions of elite chess players, a domain commonly used as a testbed for AI

Probing cosmic voids with emission-line galaxies
Frontiers in Astronomy and Space SciencesIntroductionWe aim to provide forecasts for future line intensity mapping (LIM) observations and galaxy redshift surveys, focusing on the physical properties of low-density region of the cosmic web (voids).

Diabetic Medicine, EarlyView.Abstract Aim Although hybrid closed‐loop systems (HCLS) and sensor‐augmented pump (SAP) therapy are advanced diabetes management technologies for type 1 diabetes, their relative efficacy in optimising glycaemic control is not fully established. This meta‐analysis evaluated the impact of HCLS versus SAP therapy on glucose regulation across multiple ...
