The Dark Matter Distribution in the Central Regions of Galaxy Clusters: Implications for Cold Dark Matter [PDF]

, 2003
We have undertaken a spectroscopic survey of gravitational arcs in a carefully chosen sample of six clusters, each containing a dominant brightest cluster galaxy.

The clustering of dark matter, haloes & galaxies [PDF]

, 2008
In this thesis I study the spatial distribution of galaxies, haloes and dark matter particles using a suite of state-of-art cosmological N-body simulations of the growth structure in the Universe.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Indirect Detection of Decaying Dark Matter with High Angular Resolution: The Case for Axion Search by IRCS on the Subaru Telescope

The Astrophysical Journal
Recent advances in photon detectors have provided exceptional sensitivities to dark matter with high angular resolution. Motivated by this, we present a detailed study of photon flux from dark matter decay in dwarf spheroidal galaxies (dSphs) by focusing

The Mass Discrepancy-Acceleration Relation: Disk Mass and the Dark Matter Distribution [PDF]

, 2004
The mass discrepancy in disk galaxies is shown to be well correlated with acceleration, increasing systematically with decreasing acceleration below a critical scale a0 ≈ 3700 km2 s-2 kpc-1 = 1.2 × 10-10 m s-2. For each galaxy, there is an optimal choice

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 ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

The Roman View of Strong Gravitational Lenses

The Astrophysical Journal
Galaxy–galaxy strong gravitational lenses can constrain dark matter models and the Lambda cold dark matter cosmological paradigm at subgalactic scales. Currently, there is a dearth of images of these rare systems with high signal-to-noise ratio (SNR) and

The AIDA-TNG project: Abundance, radial distribution, and clustering properties of halos in alternative dark matter models

Astronomy & Astrophysics
Warm and self-interactive dark matter cosmologies have been proposed as nonbaryonic solutions to the tensions between the Λ cold dark matter model and observations at the kiloparsec scale.

THE CENTRAL DARK MATTER DISTRIBUTION OF NGC 2976 [PDF]

, 2011
We study the mass distribution in the late-type dwarf galaxy NGC 2976 through stellar kinematics obtained with the Visible Integral Field Replicable Unit Spectrograph Prototype and anisotropic Jeans models as a test of cosmological simulations and ...
