Gravitational lensing by deformed Horava-Lifshitz black hole in rainbow gravity

Physics Letters B
In this study, we investigate the gravitational lensing effects of deformed Horava-Lifshitz black holes, considering both strong and weak-field limit approximations and incorporating the impact of rainbow functions.

From Theory to Practice: A Framework for Collaborative Anti‐Racist Research With Young Black Children

Children &Society, EarlyView.
ABSTRACT While researchers continue to make significant scholarly inroads toward the acknowledgment of Black children's agency and competencies, including their recognition of and resistance to systemic racism, practical guides to anti‐racist qualitative research with young Black children factor conspicuously less often into the contextual balance of ...

A Novel Test for MOND: Gravitational Lensing by Disk Galaxies

The Astrophysical Journal
Disk galaxies represent a promising laboratory for the study of gravitational physics, including alternatives to dark matter (DM), owing to the possibility of coupling rotation curves’ dynamical data with strong gravitational lensing (SGL) observations ...

Generating Dark Matter Subhalo Populations Using Normalizing Flows

The Open Journal of Astrophysics
Strong gravitational lensing is a powerful tool for probing the nature of dark matter, as lensing signals are sensitive to the dark matter substructure within the lensing galaxy.

Novel assessment of facial skin displacement across age groups using a custom‐designed imaging device: Evidence from French women

International Journal of Cosmetic Science, EarlyView.
Deformation fields of skin displacements indicated by vectors in a 22‐year‐old participant (a) and a 65‐year‐old volunteer (b) in different positions. These vectors represent the direction and magnitude of skin displacement at each point on the facial surface.

Equity–Equality Tensions in Police Social Media Communication With Socially Disadvantaged Neighbourhoods: The Case of Instagram

Information Systems Journal, EarlyView.
ABSTRACT This study draws on Instagram‐related data to examine how and why the equity and equality principles of fairness govern police communication with socially disadvantaged neighbourhoods on social media. Using the computationally intensive theory construction methodology and drawing on institutional theory and the framework for the interplay of ...
