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 ...

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-

Strength and deformation properties of frozen sand under a true triaxial stress condition
Soils and Foundations, 2022 In recent years, the mechanical properties of frozen soils under complex stress states have attracted significant attention; however, limited by the test apparatus, true triaxial tests on frozen soils have rarely been conducted. To study the strength and

New method for true-triaxial rock testing [PDF]
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1997 Two new and related true-triaxial apparatus are described that make use of conventional triaxial pressure vessels in combination with specially configured, high-pressure hydraulic jacks inside these vessels. The development combines advantages not found in existing facilities, including a compact design, pore-pressure and flow-through capabilities, the

Aeolian Sand Test with True Triaxial Stress Path Achieved by Pseudo-Triaxial Apparatus
Sustainability, 2023 Aeolian sand is a special roadbed filler, but its three-dimensional mechanical properties are rarely studied. To obtain the characteristic of its deformation, strength on the deviatoric plane, and failure in three dimensions, a series of triaxial drained tests on aeolian sand in the Tengger Desert, under the condition of the constant average principal ...

Loss of halo triaxiality due to bar formation [PDF]
, 2010 Cosmological N-body simulations indicate that the dark matter haloes of galaxies should be generally triaxial. Yet, the presence of a baryonic disc is believed to alter the shape of the haloes.
