Dynamical stability and galaxy evolution in LSB disk galaxies [PDF]
AIP Conference Proceedings, 1997 We demonstrate that, due to their low surface mass density and large dark matter content, LSB disks are quite stable against the growth of global bar modes. However, they may be only marginally stable against local disk instabilities. We simulate a collision between an LSB and HSB galaxy and find that, while the HSB galaxy forms a strong bar, the ...

Staphylococcus aureus AgrA Modulators From South African Antimicrobial Plants
Chemistry &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.

ChemCatChem, EarlyView.An enzyme that has been identified and characterized as capable of hydrolyzing paclitaxel (Taxol), a key anticancer drug derived from Pacific yew (Taxus brevifolia) has been identified. Molecular docking (MD) simulations map the catalytic triad and critical residues that drive substrate‐enzyme interactions. The findings indicate the catalytic potential

The Magellanic Stream in Modified Newtonian Dynamics
, 2006 The dynamics of the Magellanic Stream (MS) as a series of clouds extending from the Magellanic Clouds (MCs) to the south Galactic pole is affected by the distribution and the amount of matter in the Milky Way. We calculate the gravitational effect of the

Dynamical evolution of triplets of galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 By means of N-body simulations we study the global dynamics of triplets of galaxies, considering initial conditions starting from `maximum expansion' and in virial equilibrium. Unlike previous studies we treat galaxies self-consistently. We do not consider the influence of a primordial common halo of dark matter.

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

Testing Lorentz invariance of dark matter with satellite galaxies
, 2017 We develop the framework for testing Lorentz invariance in the dark matter sector using galactic dynamics. We consider a Lorentz violating (LV) vector field acting on the dark matter component of a satellite galaxy orbiting in a host halo. We introduce a

, 1999 Our Galaxy is a barred spiral. Recent work based on the COBE NIR data implies a small bulge-bar and a disk with a short scale-length. The corotation radius of the bar is in the range 3-4.5 kpc. The stellar density distribution beyond the end of the bar appears to be perturbed strongly by the Galaxy's spiral arms.

Dynamical friction of radio galaxies in galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2008 Abstract The distribution of luminous radio galaxies in galaxy clusters has been observed to be concentrated in the inner region. We consider the role of dynamical friction of massive galaxies (M∼ 1012.5M⊙), assuming them to be hosts of luminous radio galaxies, and show that beginning with a Navarro–Frenk–White density profile of a ...
