Testing the Surface Brightness Fluctuations Method for Dwarf Elliptical Galaxies in the Centaurus A Group
Helmut Jerjen, Ken C. Freeman, Bruno Binggeli
We have obtained deep B and R-band CCD photometry for 5 dE galaxies that were previously identified on Schmidt films covering the Cen A group region. From a Fourier analysis of the…
Optical and near-infrared spectrophotometric properties of Long Period Variables and other luminous red stars
R. Alvarez, A. Lancon, B. Plez +1
Based on a new and large sample of optical and near-infrared spectra obtained at the Mount Stromlo and Siding Spring Observatories (Lancon & Wood 1998; Lancon & Wood, in preparatio…
The environments of intermediate-redshift QSOs: 0.3 < z < 0.7
R. J. Smith, B. J. Boyle, S. J. Maddox
An angular correlation of low significance (2 sigma) is observed between 0.3 < z < 0.5 QSOs and V < 23 galaxies. Overall, the cross-correlation function between 82 intermediate-red…
Properties of Dust Grains in Planetary Nebulae -- I. The Ionized Region of NGC 6445
P. A. M. van Hoof, G. C. Van de Steene, D. A. Beintema +3
In this paper we study new infrared spectra of the evolved planetary nebula NGC 6445 obtained with ISO. These data show that the thermal emission from the grains is very cool and h…
Stellar Streams in the Solar Neighbourhood from High Resolution N-Body Simulations
R. Fux
A high-resolution N-body simulation suggests that stellar streams in the discs of barred galaxies are common and strongly time-dependent. The velocity distribution of stars in the…
The Hubble Space Telescope Key Project on the Extragalactic Distance Scale XXIV: The Calibration of Tully-Fisher Relations and the Value of the Hubble Constant
Shoko Sakai, Jeremy R. Mould, Shaun M. G. Hughes +15
This paper presents the calibration of BVRIH$ Tully-Fisher relations based on Cepheid distances to 21 galaxies within 25 Mpc, and 23 clusters within 10,000 km/s. These relations ha…
