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 ...
متن کاملMultiple 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...
متن کاملCO in late – type galaxies within the central region of Abell 1367
We present CO (J = 1 → 0) and CO (J = 2 → 1) spectra for 19 bright, late–type galaxies (spirals) in the central region of the galaxy cluster Abell 1367 (z = 0.02) from observations made with the IRAM 30–m telescope. All 19 spirals were observed at the position of their optical center and for a subset, at multiple positions. For each spiral the integrated CO (J = 1 → 0) intensity from the centra...
متن کاملCapturing 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...
متن کاملOptical spectroscopy and the UV luminosity function of galaxies in the Abell 1367 , Coma and Virgo clusters . ⋆
Optical spectroscopy and the UV luminosity function of galaxies in the Abell 1367, Coma and Virgo clusters. Abstract. Optical spectroscopy of 93 galaxies, 60 projected in the direction of Abell 1367, 21 onto the Coma cluster and 12 on Virgo, is reported. The targets were selected either because they were detected in previous Hα, UV or r ′ surveys. The present observations bring to 100% the reds...
