SHARC II 350μm continuum and archival HST J−H band maps are presented of NGC 3656, the brightest of our sample of six elliptical galaxies for which resolved CO gas disks have recently been detected with 7′′-spatial-resolution, interferometry mapping. These gas disks confirm the conclusions of earlier results showing optical dust lanes and unresolved CO that implied the common existence of molec...

The nearby dwarf elliptical galaxy NGC 205 offers a unique opportunity for high resolution studies of the interstellar medium in an elliptical galaxy. The present paper investigates the distribution of molecular gas, molecular line ratios, and the relationships between atomic gas, molecular gas, and dust in this galaxy. The line ratios 12 CO(2-1)/(1-0) and 12 CO(1-0)/ 13 CO(1-0) in one of the m...

We report 0. ′′ 5 × 0. ′′ 9 resolution, interferometric observations of the 1.3 mm CO J=2→1 line in the infrared luminous galactic merger NGC 6240 2. About half of the CO flux is concentrated in a rotating but highly turbulent, thick disk structure centered between the two radio and near-infrared nuclei. A number of gas features connect this ∼500 pc diameter central disk to larger scales.

A combination of spectral and moments analysis of the continuous X-ray flux data is used to show consistency of statistical properties of the powerful solar flares with 2D BTW prototype model of self-organized criticality.
