An MCMC Fitting Method for Triaxial Dark Matter Haloes [PDF]

, 2008
Measuring the 3D distribution of mass on galaxy cluster scales is a crucial test of the LCDM model, providing constraints on the behaviour of dark matter. Recent work investigating mass distributions of individual galaxy clusters (e.g.

On-sample water content measurement for a complete local monitoring in triaxial testing of unsaturated soils [PDF]

, 2012
To provide a complete local monitoring of the state of an unsaturated soil sample during triaxial testing, a local water content measurement device was adapted to a triaxial device comprising the measurement of local displacements (Hall effect ...

Experimental study on impact dynamics and failure characteristics of coal specimen under true triaxial conditions

Meitan xuebao, 2023
Deep coal is mostly in a three-dimensional unequal stress state. In order to study the dynamic characteristics of coal under impact load, the dynamic failure mechanics experiment of coal was carried out by true triaxial Hopkinson experimental system ...

Estimating Black Hole Masses in Triaxial Galaxies [PDF]

, 2009
Most of the super massive black hole mass estimates based on stellar kinematics use the assumption that galaxies are axisymmetric oblate spheroids or spherical.

Modeling the gravitational potential of a cosmological dark matter halo with stellar streams [PDF]

, 2016
Stellar streams result from the tidal disruption of satellites and star clusters as they orbit a host galaxy, and can be very sensitive probes of the gravitational potential of the host system. We select and study narrow stellar streams formed in a Milky-

Galaxy Clusters: Oblate or Prolate? [PDF]

, 1999
It is now well known that a combined analysis of the Sunyaev-Zel'dovich (SZ) effect and the X-ray emission observations can be used to determine the angular diameter distance to galaxy clusters, from which the Hubble constant is derived.

Weak lensing by triaxial galaxy clusters [PDF]

, 2011
Weak gravitational lensing studies of galaxy clusters often assume a spherical cluster model to simplify the analysis, but some recent studies have suggested this simplifying assumption may result in large biases in estimated cluster masses and ...

True triaxial tests on transversely isotropic unsaturated loess

Yantu gongcheng xuebao, 2022
In order to study the mechanical properties of transversely isotropic unsaturated remolded loess under complex stress paths, two groups of 15 tests are carried out using the true triaxial apparatus.

Spectral Statistics of the Triaxial Rigid Rotator: Semiclassical Origin of their Pathological Behavior [PDF]

, 2003
In this paper we investigate the local and global spectral properties of the triaxial rigid rotator. We demonstrate that, for a fixed value of the total angular momentum, the energy spectrum can be divided into two sets of energy levels, whose classical ...
