The Outer Halos of Elliptical Galaxies [PDF]
, 2010 Recent progress is summarized on the determination of the density distributions of stars and dark matter, stellar kinematics, and stellar population properties, in the extended, low surface brightness halo regions of elliptical galaxies. With integral field absorption spectroscopy and with planetary nebulae as tracers, velocity dispersion and rotation ...

The Elliptical Galaxy formerly known as the Local Group: Merging the Globular Cluster Systems [PDF]
, 2000 Prompted by a new catalogue of M31 globular clusters, we have collected together individual metallicity values for globular clusters in the Local Group. Although we briefly describe the globular cluster systems of the individual Local Group galaxies, the

On the Formation of Elliptical Galaxies [PDF]
The Astrophysical Journal, 1975 Simple collapse and violent relaxation models produce sharply cut off envelopes with ϱ(r) ∝ r–4, whereas actual elliptical galaxies have more extended envelopes approximately given by ϱ(r) ∝ r–3 as implied by Hubble's Law. Numerical models are presented, showing that when cosmological infall effects are included, galaxies are produced with more ...

The Astronomical JournalVV 191 is a nearby ( z ∼ 0.05), overlapping (occulting) galaxy pair, where a multiple-armed spiral galaxy is backlit by an elliptical galaxy. The overlap is used to derive and map dust attenuation in two James Webb Space Telescope NIRCam filters (F090W ...

Absorption Line Gradients of an Elliptical Galaxy NGC 5322 [PDF]
Journal of Astronomy and Space Sciences, 1999 Archival long-slit spectra, covering the wavelength range 4050Å - 5150Å, have been used to investigate the radial behavior of absorption line features (G4300, Fe4383, Ca4455, Fe44531, Fe4668, and Hα) of an eliptical galaxy NGC 5322.
