We present new observations of the merging system Arp 299 obtained with the IRAM Plateau de Bure interferometer. We have observed the 12CO(1 − 0), 12CO(2 − 1), 13CO(1 − 0) and HCN(1-0)lines. For the 12CO(1 − 0) line, short spacings were recovered by using 30m data; about half of the total flux is found in weak and extended emission filtered out by the interferometer. The 12CO(1 − 0)map shows th...

Evaluation of over 255 patients with sellar and parasellar lesions allowed study of the computed tomographic (CT) appearance of the cavernous sinus. Optimal visualization of the cavernous sinus was obtained with continuous contrast enhancement of both axial and coronal tomograms. The coronal projection provided imaging of cranial nerves within the cavernous sinus. The intracavernous carotid art...

We present VLA H i observations and UH88 ′′ deep optical Band R-band observations of the IR luminous merger Arp 299 (= NGC 3690 + IC 694). These data reveal a gas-rich (M HI = 3.3 × 10 9 M ⊙) optically faint (µ B ∼ >27 mag arcsec −2 , µ R ∼ >26 mag arcsec −2) tidal tail with a length of over 180 kpc. The size of this tidal feature necessitates an old interaction age for the merger (∼ >750 Myr s...
