The 1000 Brightest HIPASS Galaxies: Newly Cataloged Galaxies
The H i Parkes All-Sky Survey (HIPASS) is a blind 21-cm survey for extragalactic neutral hydrogen, covering the whole southern sky. The HIPASS Bright Galaxy Catalog (BGC; Koribalski et al. 2002) is a subset of HIPASS and contains the 1000 H i-brightest (peak flux density) galaxies. Here we present the 138 HIPASS BGC galaxies, which had no redshift measured prior to the Parkes multibeam H i surv...
متن کاملThe 1000 Brightest Hipass Galaxies: H I Mass Function and Ω Hi
We present a new accurate measurement of the H I mass function of galaxies from the HIPASS Bright Galaxy Catalog, a sample of 1000 galaxies with the highest H I peak flux densities in the southern (δ < 0) hemisphere (Koribalski et al. 2003). This sample spans nearly four orders of magnitude in H I mass (from log(MHI⁄ M⊙) + 2logh75 = 6.8 to 10.6) and is the largest sample of H I selected galaxie...
متن کاملThe Origin of the Brightest Cluster Galaxies
Most clusters and groups of galaxies contain a giant elliptical galaxy in their centres which far outshines and outweighs normal ellipticals. The origin of these brightest cluster galaxies is intimately related to the collapse and formation of the cluster. Using a large cosmological N-body simulation of cluster collapse, we show how hierarchical merging naturally produces a giant, central ellip...
متن کاملThe stellar content of brightest cluster galaxies
We present near-infrared K-band spectroscopy of 21 elliptical or cD Brightest Cluster Galaxies (BCGs), for which we have measured the strength of the 2.293 µm CO stellar absorption feature. We find that the strength of this feature is remarkably uniform among these galaxies, with a smaller scatter in equivalent width than for the normal elliptical population in the field or clusters. The scatte...
متن کاملRadial kinematics of brightest cluster galaxies
This is the first of a series of papers devoted to the investigation of a large sample of brightest cluster galaxies (BCGs), their kinematic and stellar population properties, and the relationships between those and the properties of the cluster. We have obtained high signal-to-noise ratio, long-slit spectra of these galaxies with Gemini and WHT with the primary purpose of investigating their s...
