Statistical methods in weak gravitational lensing [PDF]

open access: yes, 2015
This thesis studies several topics in the area of weak gravitational lensing and addresses some key statistical problems within this subject. A large part of the thesis concerns the measurement of galaxy shapes for weak gravitational lensing and the ...

How Many Worlds Could There Be? David Lewis and Advanced Modalizing

open access: yesAnalytic Philosophy, EarlyView.
ABSTRACT Advanced modalizing, namely, possibilities and necessities concerning modal space itself, is problematic for a Lewis‐style analysis of modality. A popular solution, proposed by Divers, postulates explicit semantic clauses for a collapse of advanced modalizing, to the conclusion that all such matters are, if true in the first place, both ...

Finding the boundary: Using galaxy membership to inform galaxy cluster extent through machine learning

open access: yesThe Open Journal of Astrophysics
The spatial extent of the environment's impact on galaxies marks a transitional region between cluster and field galaxies. We present a data-driven method to identify this region in galaxy clusters with masses $M_{200\rm ,mean}>10^{13} M_{\odot}$ at $z =

The S-PLUS Fornax Project (S+FP): Fornax-like clusters in cosmological hydrodynamical simulations

open access: yesAstronomy & Astrophysics
Context. The Fornax cluster, the second-nearest rich galaxy cluster, constitutes a suitable laboratory to explore the evolution of galaxies in a dense environment.

BerryBox: An affordable computer vision system for postharvest phenotyping of cranberry and other small fruits

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Fruit size, shape, color, and percent fruit rot are important quality traits for breeding cranberry (Vaccinium macrocarpon Ait.). Image analysis can be used to measure these traits, but affordable hardware for standardized image capture and integrated user‐friendly software pipelines are lacking.

Euclid Quick Data Release (Q1)

open access: yesAstronomy & Astrophysics
The matter around galaxy clusters is distributed over several filaments, reflecting their positions as nodes in the large-scale cosmic web. The number of filaments connected to a cluster, i.e.

The Role of Cluster Environments in Quiescent Galaxy Stellar Halo Assembly

open access: yesThe Astrophysical Journal
External interactions drive galaxy stellar mass growth and morphological evolution. As stellar halos—assembled largely via hierarchical accretion—preserve signatures of these processes, their growth probes how environment regulates galaxy evolution.

Lyman continuum escaping from in situ formed stars in a tidal bridge at z = 3

open access: yesAstronomy & Astrophysics
We present an analysis of archival JWST NIRSpec IFS and HST imaging observations of the z = 3 Lyman continuum emitter (LCE) candidate LACES104037. We show that a nearby galaxy, denoted LACES104037-S, has a redshift offset from the main galaxy by only ...

Exploring the Potential of Unmanned Aerial System‐Based Topographic Indices Maps to Evaluate Storm Drain Positioning

open access: yesJournal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT Urbanisation, climate uncertainty, and limited city budgets have heightened the need for efficient urban drainage management. While advanced hydrodynamic models assess the performance of drainage networks, they are computationally intensive, time‐consuming, and expensive.
