A Preferred Orientation Angle for Bipolar Planetary Nebulae
Galaxies, 2020 We present preliminary results from measuring Galactic orientation angles of 766 elliptical and bipolar Planetary Nebulae (PNe) in the Hong Kong/Australian Astronomical Observatory/Strasbourg Observatory H-alpha Planetary Nebula research platform and ...

A Potential Galaxy Threshing System in the Cosmos Field [PDF]
, 2006 We report on the discovery of a new potential galaxy threshing system in the COSMOS 2 square degree field using the prime-focus camera, Suprime-Cam, on the 8.2 m Subaru Telescope. This system consists of a giant elliptical galaxy with $M_V \approx -21.6$

The Manifold of Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 1983 The significant number of dimensions of the manifold is two. Notwithstanding the contamination of the second dimension by projection effects, there are arguments for an intrinsic variation.

Elliptical Galaxies with Shells [PDF]
International Astronomical Union Colloquium, 1984 A considerable number of otherwise normal elliptical galaxies show sharp edged, low surface brightness concentric features, often at very large radii from the parent galaxy. Features like this are visible in some of the photographs presented by Arp (1966).

Dynamical Models of Spherical Galaxies with Massive Halo [PDF]
Journal of Astronomy and Space Sciences, 2003 Using the Schwarzschild's linear programming technique, we obtained the general solutions of the collisionless Bolzmann equation describing the spherical galaxy in dynamical equilibrium.

Cold gas in elliptical galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 We explore the evolution of the cold gas (molecular and neutral hydrogen) of elliptical galaxies and merger remnants ordered into a time sequence on the basis of spectroscopic age estimates. We find that the fraction of cold gas in early merger remnants decreases significantly for ~1-2Gyr, but subsequent evolution toward evolved elliptical systems sees

The Astrophysical Journal Supplement Series, 2023 We investigate the roles of major and minor mergers during brightest cluster galaxy (BCG) assembly using surface brightness profiles, line indices, and fundamental plane relations.

Abundance ratios in dwarf elliptical galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We determine abundance ratios of 37 dwarf ellipticals (dEs) in the nearby Virgo cluster. This sample is representative of the early-type population of galaxies in the absolute magnitude range -19.0 < Mr < -16.0. We analyze their absorption line-strength indices by means of index-index diagrams and scaling relations and use the stellar population ...
