The relation between bar formation, galaxy luminosity, and environment

open access: yes, 2013
We derive the bar fraction in three different environments ranging from the field to Virgo and Coma clusters, covering an unprecedentedly large range of galaxy luminosities (or, equivalently, stellar masses).

Galaxy interactions I: Major and minor mergers [PDF]

open access: bronze, 2011
Aims. We study galaxy pair samples selected from the Sloan Digital Sky Survey (SDSS-DR7) and we perform an analysis of minor and major mergers with the aim of investigating the dependence of galaxy properties on interactions. Methods.

Staphylococcus aureus AgrA Modulators From South African Antimicrobial Plants

open access: yesChemistry &Biodiversity, EarlyView.
The study workflow utilized validated in silico [molecular docking, fingerprinting, pharmacokinetics prediction, molecular dynamics (MD) simulation, ligand‐protein contact maps] tools to bioprospect a wide variety of metabolites surveyed from South African plants with antimicrobial activities, and target them against the key S.

Ring or No Ring—Revisiting the Multiphase Nuclear Environment in M31

open access: yesThe Astrophysical Journal
Nuclear rings, prevalent in barred galaxies, are essential to understanding gas transport toward galactic nuclei. However, the peculiar nuclear ring in our neighboring galaxy M31 remains poorly understood.

LGBTQ+ Affirmative Care Training in Counselor Education: A Community‐Based Inquiry

open access: yesCounselor Education and Supervision, EarlyView.
ABSTRACT Counselor educators, counselors‐in‐training, and LGBTQ+ community members engaged in a community‐based qualitative inquiry exploring LGBTQ+ affirmative care education. Findings revealed counselor educators’ components and delivery of content, developmental implications for applying LGBTQ+ affirmative care, and gaps between education and LGBTQ+

UV–Vis Spectra of Carbonic Acid: Rationalizing Experimental Redshifts between Monomer and Bulk based on (H2CO3)n Calculations

open access: yesChemPhysChem, EarlyView.
In bulk carbonic acid (e.g., in interstellar icy dust grains) cluster formation produces two distinct UV‐Vis spectral features redshifted by ≈2 eV (25 nm) and by ≈5 eV (80 nm) compared to gas phase single molecule carbonic acid 's adiabatic ionization energy. Theory and experiment were used to investigate the origin of these shifts.

The graviton background: a new way to quantum gravity [PDF]

open access: yes, 2006
Graviton pairing and destruction of these pairs under collisions with bodies may lead to the Newtonian attraction. It opens us a new way to a very-low-energy quantum gravity model.

Bar-spheroid interaction in galaxies

open access: yesThe Astrophysical Journal, 1992
The secular evolution of barred galaxies is explored using N-body simulation and linear analysis. In particular, we examine the interaction between bars and spheroidal components of galaxies. According to our calculations, this interaction drives secular transfer of angular momentum from bars to spheroids, primarily through resonant coupling.
