Image Simulations for Strong and Weak Gravitational Lensing [PDF]
Symmetry, 2020 Gravitational lensing has been identified as a powerful tool to address fundamental problems in astrophysics at different scales, ranging from exoplanet identification to dark energy and dark matter characterization in cosmology. Image simulations have played a fundamental role in the realization of the full potential of gravitational lensing by ...

The Depositional Record, EarlyView.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.

The Astrophysical JournalStrongly lensed binary neutron star (NS–NS) mergers are expected to be observed once LIGO/Virgo/Kagra reaches the planned A+ or proposed A# sensitivity. We demonstrate that the relative transverse velocity of the source-lens system can be constrained by ...

The Astrophysical Journal Letters, 2023 We report the discovery of COOL J0335−1927, a quasar at z = 3.27 lensed into three images with a maximum separation of 23.″3 by a galaxy cluster at z = 0.4178. To date, this is the highest redshift wide-separation lensed quasar known.

Measuring Bending Rigidity and Compression Resistance in Pickering Layers
European Journal of Lipid Science and Technology, EarlyView.This graphical abstract presents the mechanical response of Pickering layers of polystyrene beads (PBs) and clay particles (CPs) under compression. PBs exhibit buckling at 40–70 mN/m, whereas CPs show no buckling. Experimental force–compression curves highlight distinct deformation behaviors, and deviations in bending rigidity emphasize interparticle ...

Harnessing Unresolved Lensed Quasars: The Mathematical Foundation of the Fluctuation Curve
The Astrophysical Journal, 2023 Strong gravitational lensed quasars (QSOs) have emerged as powerful and novel cosmic probes as they can deliver crucial cosmological information, such as a measurement of the Hubble constant, independent of other probes. Although the upcoming LSST survey

Strong Lens Models for 37 Clusters of Galaxies from the SDSS Giant Arcs Survey
, 2019 We present strong gravitational lensing models for 37 galaxy clusters from the SDSS Giant Arcs Survey. We combine data from multi-band Hubble Space Telescope WFC3imaging, with ground-based imaging and spectroscopy from Magellan, Gemini, APO, and MMT, in ...

The Journal of Humanistic Counseling, EarlyView.ABSTRACT Survivors and refugees of war often have mental, behavioral, emotional, and spiritual consequences from undergoing civil unrest. In many cases, counselors utilize cognitively‐based therapies as the recommended treatment to alleviate these issues.
