Hickson 62

Hα Imaging of the Hickson Compact Group 62

We report results of a search for optical emission line gas in the Hickson compact group 62. From narrow band (Hα) imaging observations we estimate 10 4 M ⊙ of ionized hydrogen gas within the central regions of three of the galaxies in the group. There has been considerable interest in this group since ROSAT detected an extended halo of diffuse X-ray emission, possibly with a cooling flow at th...

Hickson 96 : a physical compact group ⋆

We analyze the morphology and dynamics of the galaxies of the Hickson 96 compact group by means of deep CCD images in the B, V and R photometric bands and long–slit spectroscopy. The four galaxies of this spiral rich group show signs of gravitational interaction. Two long tails come out from the contact region of the close pair H96ac. It is also there where both galaxies, bi-symmetrical in thei...

Chapter 62

The study highlights a deeper insight of the genes involved in the degradation of diverse number of refractory environmental pollutants, the pool of available genomic data needs to be enhanced. There seems to be a high urgency for such ecologically important microbes to be sequenced and their genomes to be critically analyzed. Sphingobium indicum B90A is the most efficient degrader of Hexachlor...

Where is the Neutral Atomic Gas in Hickson Groups?

We have analyzed the total HI contents of 72 Hickson compact groups of galaxies (HCGs) and the detailed spatial distributions and kinematics of HI within a subset of 16 groups using the high angular resolution observations obtained with the VLA in order to investigate a possible evolutionary scenario for these densest systems in the present day galaxy hierarchy. For the more homogeneous subsamp...
