Chandra 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 کاملProbing 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 کاملMulti - wavelength Study of Young Massive Star Clusters in the Interacting Galaxy ARP 24
We made a multi-wavelength study of young massive star clusters (YSCs) in the interacting galaxy ARP 24, using the optical and ultraviolet images from Hubble Space Telescope (HST), Sloan Digital Sky Survey, and Galaxy Evolution Explorer; the mid-infrared images from Spitzer Space Telescope; and the narrow-band Hα image and optical spectra from the NAOC 2.16 m telescope. Based on the HST images,...
متن کاملPropagating Star Formation in the Collisional Ring Galaxy Arp 10
Propagating star formation in a collisional ring galaxy Arp 10 is investigated by a complex approach , which includes the broad-and narrow-band photometry, long-slit spectroscopy, and scanning Fabry-Perot spectroscopy. The ionized gas velocity field obtained with best spatial resolution to date indicates a non-isotropic expansion of the outer ring with a maximum velocity 110 km s −1. Strong ver...
متن کاملPowerful H2 Emission and Star Formation on the Interacting Galaxy System Arp 143: Observations with Spitzer and Galex
We present new mid-infrared (5− 35μm) and ultraviolet (1539 – 2316 Å) observations of the interacting galaxy system Arp 143 (NGC 2444/2445) from the Spitzer Space Telescope and GALEX. In this system, the central nucleus of NGC 2445 is surrounded by knots of massive star-formation in a ring-like structure. We find unusually strong emission from warm H2 associated with an expanding shock wave bet...
