Probing the Dust-enshrouded Regions of the Interacting Galaxy System Arp 299 : a Near-infrared Study
We present high spectral resolution (j/dj + 103) Pab(1.28 km) and Brc(2.17 km), 3.29 km dust feature, and near-infrared broadband images of the Arp 299\NGC 3690/IC 694 galaxy system. The emission is found to be concentrated at the positions of three active regions, known as sources A, B, and C. From our Brc/Pab Ñux ratio we Ðnd the visual extinction toward the ionized gas in A, B, and C is D6, ...
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 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 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 کاملDust Enshrouded Agb Variables in the Lmc
The luminosities and periods of obscured AGB stars in the LMC are discussed using a combination of ISO and ground-based infrared photometry. The bolometric luminosities of these stars fall close to an extrapolation of the period-luminosity relation derived for oxygen-rich Mira variables, with both oxygenand carbon-rich stars falling close to the same relation. It has been known for many years t...
