Form flows function: Learner‐centered game Re‐design in a STEM classroom

British Educational Research Journal, EarlyView.
Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.

Revisiting the Fundamental Metallicity Relation with Observation and Simulation

The Astrophysical Journal Letters
The gas-phase metallicity of galaxies is regulated by multiple astrophysical processes, which makes it a crucial diagnostic of galaxy formation and evolution.

Clustering and redshift-space distortions in QSO and galaxy surveys [PDF]

, 2006
In this thesis, we exploit the potential of existing QSO and galaxy surveys for investigating the nature of the large scale structure in the Universe. A detailed analysis of clustering and redshift- space distortions allows us to constrain cosmological ...

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

Deep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Stellar Populations with MaNGA: Iron Kink and Nitrogen Fuzz

The Astrophysical Journal
Recent analysis of 2968 MaNGA early-type galaxies has yielded two notable trends with velocity dispersion ( σ ) not previously discussed in the literature. First, Fe abundance rises with σ but only until σ  ≈ 100 km s ^−1 , after which it falls.

The host of GRB 060206 : kinematics of a distant galaxy [PDF]

, 2008
Context. GRB afterglow spectra are sensitive probes of interstellar matter along the line-of-sight in their host galaxies, as well as in intervening galaxies. The rapid fading of GRBs makes it very difficult to obtain spectra of sufficient resolution and

Radial Gradients and Intrinsic Scatter in MaNGA Galaxies

The Astrophysical Journal Supplement Series
We derive stellar population parameters and radial gradients within 0.65 R _e for spatially resolved spectra of 2968 early-type galaxies from MaNGA, spanning stellar velocity dispersions ( σ ) of 50–340 km s ^−1 .

The evolution of dark matter substructure [PDF]

, 2001
This thesis investigates the dynamical evolution of systems orbiting within deeper potentials. Initially we use a simple satellite-halo interaction to study the dynamical processes that act on orbiting systems and we compare these results to analytical ...

Episodic Star Formation. I. Overview and Scatter of the Star-forming Main Sequence

The Astrophysical Journal
There is mounting evidence for episodic star formation cycles in both high- and low-redshift galaxies. This paper aims to understand the detailed physical processes behind such behaviors and investigate how such an episodic star-forming scenario can ...

A study of radio continuum emission of the Milky Way Galaxy [PDF]

, 1996
The synchrotron emissivity distribution of the Milky Way Galaxy has been modelled from the 408 MHz allsky survey of Haslam et al.(1982) after separation of its thermal component with the help of IRAS 60 micron emission(Broadbent et al 1989).
