The PN.S elliptical galaxy survey: A standard ΛCDM halo around NGC 4374? [PDF]

, 2010
As part of our current programme to test ACDM predictions for dark matter (DM) haloes using extended kinematical observations of early-type galaxies, we present a dynamical analysis of the bright elliptical galaxy NGC 4374 (M84) based on ∼450 planetary ...

The dust morphology of the elliptical Galaxy M 86 with SPIRE [PDF]

, 2010
We present Herschel-SPIRE observations at 250-500 mu m of the giant elliptical galaxy M 86 and examine the distribution of the resolved cold dust emission and its relation with other galactic tracers.

Tracing Galaxy Evolution by Their Present-Day Luminosity Function

Open Astronomy, 2011
Galaxy luminosity functions are derived for different morphological types and various colors of galaxies, to trace the evolutionary effects which a priori should be different for void and supercluster galaxies.

The Planetary Nebula Spectrograph elliptical galaxy survey: the dark matter in NGC 4494 [PDF]

, 2008
We present new Planetary Nebula Spectrograph observations of the ordinary elliptical galaxy NGC 4494, resulting in positions and velocities of 255 planetary nebulae out to seven effective radii (25 kpc).

Dearth of dark matter or massive dark halo? Mass-shape-anisotropy degeneracies revealed by nmagic dynamical models of the elliptical galaxy NGC 3379 [PDF]

, 2008
Recent results from the Planetary Nebula Spectrograph (PNS) survey have revealed a rapidly falling velocity dispersion profile in the nearby elliptical galaxy NGC 3379, casting doubts on whether this intermediate-luminosity galaxy has the kind of dark ...

ABSORPTION LINE GRADIENTS IN THE SPECTRUM OF AN ELLIPTICAL GALAXY NGC 5864A [PDF]

Journal of Astronomy and Space Sciences, 1999
The archival long-slit spectra, covering the wavelength range 4050 ~ 5150 Å, have been used to investigate the radial behavior of absorption line fea-tures (G4300, Fe4383, Ca4455, Fe4531, and Hβ) of an elliptical galaxy NGC 5846A.

THE ELLIPTICITIES OF GALAXIES IN GALAXY CLUSTERS OF DIFFERENT MORPHOLOGICAL TYPE

Odessa Astronomical Publications, 2014
The distribution of galaxy ellipticities was analyzed for 207 rich PF galaxy clusters found in the Munster Red Sky Survey Galaxy Catalogue. Clusters with BM types from a comparison with the ACO catalogue were also classified on the new scheme.
