Uncertainties in Parameters Estimated with Neural Networks: Application to Strong Gravitational Lensing [PDF]
In Hezaveh et al. we showed that deep learning can be used for model parameter estimation and trained convolutional neural networks to determine the parameters of strong gravitational-lensing systems.

Gravitational lensing by a magnetized compact object in the presence of plasma [PDF]
In the weak field approximation, we study the gravitational lensing by spherical symmetric compact object immersed in magnetic field in the presence of magnetized plasma. The external magnetic field causes the split of the deflection angle of the photon,

Becoming inclusive: Developing pre‐service teachers' orientations towards their practice in Scotland
Abstract This article presents findings, from a case study with a cohort of third‐year undergraduate pre‐service teachers (PSTs) in Scotland, regarding their ideas about inclusion and curricular justice, as they concurrently encountered practice and theory.

Gravitational lensing effects of black hole with conformally coupled scalar hair
In this paper, we investigate the gravitational lensing effects in the weak and strong field limits of a static black hole with conformally coupled scalar field.

Constraining the abundance of primordial black holes with gravitational lensing of gravitational waves at LIGO frequencies [PDF]
Gravitational waves from binary black holes that are gravitationally lensed can be distorted by small microlenses along the line of sight. Microlenses with masses of a few tens of solar masses, and that are close to a critical curve in the lens plane ...

The dark matter of gravitational lensing [PDF]
We review progress in understanding dark matter by astrophysics, and particularly via the effect of gravitational lensing. Evidence from many different directions now all imply that five sixths of the material content of the universe is in this mysterious form, separate from and beyond the ordinary "baryonic" particles in the standard model of particle

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.

A deconstruction of methods to derive one-point lensing statistics
Gravitational lensing is a crucial tool for exploring cosmic phenomena, providing insights into galaxy clustering, dark matter, and dark energy. Given the substantial computational demands of $N$-body simulations, approximate methods like $\texttt ...
