HOLISMOKES

Astronomy & Astrophysics
Strong gravitationally lensed supernovae (LSNe), though rare, are exceptionally valuable probes for cosmology and astrophysics. Upcoming time-domain surveys such as the Vera Rubin Observatory’s Legacy Survey of Space and Time (LSST) offer a major ...

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 ...

Residual Test to Search for Microlensing Signatures in Strongly Lensed Gravitational Wave Signals

The Astrophysical Journal
When a gravitational wave signal encounters a massive object, such as a galaxy or galaxy cluster, it undergoes strong gravitational lensing, producing multiple copies of the original signal.

Microlensing-Based Studies of the Unresolved Structure of AGNs and the Composition of Lensing Galaxies

Open Astronomy, 2011
Multiple images of quasars formed by gravitational lensing are typically seen through the lensing galaxy. The granulation of the galaxy in stars or other compact objects induces local (‘microscopic’) but strong fluctuations in the gravitational potential

Discovering Strong Gravitational Lenses in the Dark Energy Survey with Interactive Machine Learning and Crowd-sourced Inspection with Space Warps

The Astrophysical Journal
We conduct a search for strong gravitational lenses in the Dark Energy Survey (DES) Year 6 imaging data. We implement a pre-trained Vision Transformer (ViT) for our machine learning (ML) architecture and adopt interactive machine learning to construct a ...

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.

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 ...

On the inversion methods of strong gravitational lensing [PDF]

, 2007
In dieser Dissertation präsentiere ich eine neue Methode zur Inversion der Linsengleichung. Der präsentierte Algorithmus basiert auf dem Modifizierten Hausdorff- Abstand zwischen beobachteten und modell- erzeugten Bögen als eine Funktion der Fit-Güte.

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 ...
