A Study of Catalogued Nearby Galaxy Clusters in the SDSS-DR4: I. Cluster Global Properties

, 2007
We have selected a sample of 88 nearby (z 800$ km s$^{-1}$). However, the local environment could play a key role in galaxy evolution for low mass clusters.Comment: 19 pages, 11 figures, accepted for publication in A&

The redshift-space two-point correlation functions of galaxies and groups in the Nearby Optical Galaxy sample [PDF]

, 2001
We use the two-point correlation function in redshift space, $\xi(s)$, to study the clustering of the galaxies and groups of the Nearby Optical Galaxy (NOG) sample, which is a nearly all-sky, complete, magnitude-limited sample of $\sim$7000 bright and ...

Linking early‐ and late‐type galaxies to their dark matter haloes [PDF]

, 2002
Using data from the 2 Degree Field Galaxy Redshift Survey (2dFGRS) we compute the conditional luminosity functions (CLFs) of early- and late-type galaxies.

Understanding Degradation Mechanisms in Water‐In‐Salt Electrolyte. Part 2: Impact of the Electrochemical Parameters on the Cycling Behavior of LiFePO4 versus TiS2

Batteries &Supercaps, EarlyView.
Cycling water‐in‐salt batteries involves complex degradation processes that require multiprobe analysis. Using online electrochemical mass spectrometry (OEMS), postmortem X‐ray photoemission spectroscopy (XPS) (including hard‐XPS), and scanning electron microscopy (SEM), the degradation mechanisms are examined in composite electrodes (TiS2 and LiFePO4)

Probing the effect of the protocluster environment on galaxy morphology at z = 2.23

Astronomy & Astrophysics
Context. As galaxies evolve in dense cluster and protocluster environments, they interact and quench their star formation. This gradually transforms the dominant galaxy population from star-forming galaxies to quiescent red galaxies.

Dark Matter in Late-type Dwarf Galaxies

, 1998
Previous studies of dwarf irregular galaxies have mostly found that these systems have slowly rising rotation curves and that they are dominated by dark matter, even well within the optical disk. However, based on new observations and a different technique to derive rotation curves, we find that the rotation curves may be steeper and that dark matter ...

1.65 Micron (H Band) Surface Photometry of Galaxies. VI. The History of Star Formation in Normal Late-Type Galaxies [PDF]

, 2000
We have collected a large body of near-IR (H band), UV (2000 Å), and Hα measurements of late-type galaxies. These are used jointly with spectral evolutionary synthesis models to study the initial mass function (IMF) in the mass range m > 2 M⊙.

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.

Minor-merger-induced Star Formation Rejuvenation in an Elliptical Radio-loud Quasar Host, 3C 59

The Astrophysical Journal
We report a rare case where an elliptical radio-loud quasar host, 3C 59, rejuvenates star formation activity through minor mergers with its nearby satellite galaxies.
