Molecular gas in the system of merging galaxies Arp 299 ?
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...
متن کاملTidal Tail in the Luminous Infrared Merger Arp 299
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...
متن کاملA 180 Kiloparsec Tidal Tail in the Luminous Infrared Merger Arp 299
We present VLA H I observations and University of Hawaii 88 inch (2.2 m) deep optical Band R-band observations of the IR-luminous merger Arp 299 (\NGC 3690 ] IC 694). These data reveal a gas-rich optically faint mag arcsec~2, mag arcsec~2) tidal tail (MH I\ 3.3] 109 M_) (kB Z 27 kR Z 26 with a length of over 180 kpc. The size of this tidal feature necessitates an old interaction age for the mer...
متن کاملChandra Observations of the X-ray Luminous Star-forming Galaxy Merger Arp 299
We report results of a Chandra observation of the X-ray luminous star-forming galaxy Arp299 (NGC3690/IC694). We detect 18 discrete X-ray sources with luminosities above ∼ 10 39 erg s −1 (0.5-8.0 keV band), which contribute ∼ 40% of the total galactic emission in this band. The remaining emission is associated with a diffuse component spatially coincident with regions of widespread star-formatio...
متن کاملARP/wARP and molecular replacement.
The aim of ARP/wARP is improved automation of model building and refinement in macromolecular crystallography. Once a molecular-replacement solution has been obtained, it is often tedious to refine and rebuild the initial (search) model. ARP/wARP offers three options to automate that task to varying extents: (i) autobuilding of a completely new model based on phases calculated from the molecula...
