We present a strong lensing analysis of COOL J1241+2219, the brightest known gravitationally lensed galaxy at z ≥ 5, based on new multiband Hubble Space Telescope (HST) imaging data. The lensed galaxy has a redshift of z = 5.043, placing it shortly after

Strong gravitational lensing and dark energy complementarity [PDF]
In the search for the nature of dark energy most cosmological probes measure simple functions of the expansion rate. While powerful, these all involve roughly the same dependence on the dark energy equation of state parameters, with anticorrelation between its present value w_0 and time variation w_a.

Abstract Many newcomer children spend a ‘silent year’ in elementary school classrooms while they adjust to a new culture and language. This often delays inclusion in learning and forming friendships with peers. For refugee children with disabilities (RCDs) this phase may last for 3 years or more, impacting their mental health and sense of belonging ...

Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

Photochemical Surface Degradation in Spiropyran Based Films
Monitoring of photoswitching surface properties using molecular photochromes can give misleading results due to primary inner filter effects. The surface layer can degrade but then protect deeper layers from damage, leading to misassignment of the origin of light driven changes in surface energy.

Curvature from Strong Gravitational Lensing: A Spatially Closed Universe or Systematics? [PDF]
Model-independent constraints on the spatial curvature are not only closely related to important problems, such as the evolution of the universe and properties of dark energy, but also provide a test of the validity of the fundamental Copernican ...

A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.
