Numerical modelling of Auriga's Wheel - a new ring galaxy

, 2012
We model the formation of Auriga's Wheel - a recently discovered collisional ring galaxy. Auriga's Wheel has a number of interesting features including a bridge of stars linking the neighbouring elliptical to the ring galaxy, and evidence for components ...

The Stellar Kinematics of Elliptical Galaxies [PDF]

Symposium - International Astronomical Union, 1987
The kinematic properties of elliptical galaxies are summarized. New developments are discussed in four areas: (i) the Faber-Jackson relation and the role of second parameters (ii) the luminosity-rotation relation (iii) the figures of elliptical galaxies and (iv) the mass-to-light ratio as a function of radius.

Chandra X-Ray Observations of the X-Ray Faint Elliptical Galaxy NGC 4697 [PDF]

, 2001
A Chandra ACIS S3 observation of the X-ray faint elliptical galaxy NGC 4697 resolves much of the X-ray emission (61% of the counts from within one effective radius) into 90 point sources, of which ~80 are low-mass X-ray binaries (LMXBs) associated with ...

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK

Journal of Research in Science Teaching, Volume 62, Issue 8, Page 1902-1922, October 2025.
ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

Near-IR TRGB Distance to Dwarf Elliptical Galaxy NGC 147 [PDF]

Journal of Astronomy and Space Sciences, 2007
We report the distance modulus of nearby dwarf elliptical galaxy NGC 147 estimated from the Tip of Red-giant Branch (TRGB) method applying to the color-magnitude diagrams and luminosity functions in the near-infrared JHK bands.

The Planetary Nebula System and Dynamics in the Outer Halo of NGC 5128

, 2003
The halos of elliptical galaxies are faint and difficult to explore, but they contain vital clues to both structure and formation. We present the results of an imaging and spectroscopic survey for planetary nebulae (PNe) in the nearby elliptical NGC 5128.

Simulations of Galaxy Formation in a ΛCDM Universe. III. The Dissipative Formation of an Elliptical Galaxy [PDF]

, 2003
We examine the dynamical structure of an elliptical galaxy simulated in the ΛCDM scenario. The morphology of the galaxy evolves dramatically over time in response to the mode and timing of mass accretion; smooth deposition of cooled gas leads to the ...

Searching for tidal tails - investigating galaxy harassment

, 2005
Galaxy harassment has been proposed as a physical process that morphologically transforms low surface density disc galaxies into dwarf elliptical galaxies in clusters.

A review of multiscale numerical modeling of rock mechanics and rock engineering

Deep Underground Science and Engineering, Volume 4, Issue 3, Page 382-405, September 2025.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...
