Lactea: Web‐Based Spectrum‐Preserving Multi‐Resolution Visualization of the GAIA Star Catalog

Computer Graphics Forum, EarlyView.
Abstract The explosion of data in astronomy has resulted in an era of unprecedented opportunities for discovery. The GAIA mission's catalog, containing a large number of light sources (mostly stars) with several parameters such as sky position and proper motion, is playing a significant role in advancing astronomy research and has been crucial in ...

A Strong Gravitational Lens Is Worth a Thousand Dark Matter Halos: Inference on Small-scale Structure Using Sequential Methods

The Astrophysical Journal
Strong gravitational lenses are a singular probe of the Universe’s small-scale structure—they are sensitive to the gravitational effects of low-mass (

Children's agencies navigating sexism and LGBTI+ phobia in Santiago de Chile's primary school

Children &Society, EarlyView.
Abstract Through their talk, actions and interactions, children actively shape and develop notions of gender and sexuality. This research delves into the realm of children's agency to explore the ways children act and react to instances of sexism and LGBTI+ phobia.

Galaxy–Galaxy Strong Lensing with U-Net (GGSL-UNet). I. Extracting Two-dimensional Information from Multiband Images in Ground and Space Observations

The Astrophysical Journal Supplement Series
We present a novel deep learning method to separately extract the two-dimensional flux information of the foreground galaxy (deflector) and background system (source) of galaxy–galaxy strong-lensing events using U-Net (GGSL-UNet for short). In particular,

Understanding Child Sexual Exploitation in Australia: An Empirical Contribution to the Evidence Base

Children &Society, EarlyView.
ABSTRACT Attention has been given to child sexual exploitation (CSE) internationally yet there is limited evidence about the issue deriving from Australian contexts, particularly so for understanding this form of sexual abuse. This qualitative study explored CSE from the perspectives of child protection and out‐of‐home caseworkers (N = 15) from across ...

The Symbolistic Christology in Frantz Fanon's Existentialist Thought

Dialog, EarlyView.
ABSTRACT This article attempts to answer a provocative question: Can existentialist thought provide insights into the nature of Christ? Specifically, what might we learn about Christ from existentialist such as Frantz Fanon, even if only implicitly? In offering a response to the question, I propose a symbolistic Christology through an examination of ...
