Multiple merging in the Abell cluster 1367 . ⋆

We present a dynamical analysis of the central ∼ 1.3 square degrees of the cluster of galaxies Abell 1367, based on 273 redshift measurements (of which 119 are news). From the analysis of the 146 confirmed cluster members we derive a significantly non-Gaussian velocity distribution, with a mean location CBI = 6484±81 km s −1 and a scale SBI = 891 ± 58 km s −1. The cluster appears elongated from...

Capturing a star formation burst in galaxies infalling onto the cluster Abell 1367

The discovery of a striking astrophysical laboratory in the cluster of galaxies Abell 1367 (Sakai et al. 2002) is confirmed with independent imaging and spectroscopic observations and further investigated in the present analysis. Two giant and ten dwarf/HII galaxies, members to a group, are simultaneously undergoing a burst of star formation. Redshift measurements suggest that the group galaxie...

Temperature Structure in Abell 1367

We study the temperature structure of the rich cluster of galaxies Abell 1367 using two independent methods of correcting for the ASCA PSF. The results of the two methods are in excellent agreement and give solid evidence of a strong and localized shock in the intracluster medium (ICM). Our analysis suggests that we are observing the merger of two subclusters. We find that the lower luminosity ...

The Star-Forming Molecular Gas in High-Redshift Submillimetre Galaxies

We present a model for the CO molecular line emission from high-redshift Submillimetre Galaxies (SMGs). By combining hydrodynamic simulations of gas-rich galaxy mergers with the polychromatic radiative transfer code, SUNRISE, and the 3D non-LTE molecular line radiative transfer code, TURTLEBEACH, we show that if SMGs are typically a transient phase of major mergers, then their observed compact ...

Molecular Gas in the Low Metallicity , Star Forming Dwarf Ic

We present a complete survey of CO (1 → 0) emission in the Local Group dwarf irregular IC 10. The survey, conducted with the BIMA interferometer, covers the stellar disk and a large fraction of the extended H I envelope with the sensitivity and resolution necessary to detect individual giant molecular clouds (GMCs) at the distance of IC 10 (950 kpc). We find 16 clouds with a total CO luminosity...
