Tidal 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 کاملMolecular 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 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 کاملar X iv : a st ro - p h / 06 10 88 8 v 1 3 0 O ct 2 00 6 The water megamaser in the merger system Arp 299
We present preliminary results of an interferometric study of the water megamaser in the merger system Arp 299. This system is composed of two main sources: IC 694 and NGC 3690. There is clear evidence that most of the water maser emission is associated with the nucleus of the latter, confirming the presence of an optically obscured AGN as previously suggested by X-ray observations. Furthermore...
