We present a new analysis of HST , Spitzer telescope imaging and VLT imaging and spectroscopic data of a bright lensed galaxy at z =1.0334 in the lensing cluster Abell 2667 .
Using this high-resolution imaging we present an updated lens model that allows us to fully understand the lensing geometry and reconstruct the lensed galaxy in the source plane .
This giant arc gives a unique opportunity to peer into the structure of a high-redshift disk galaxy .
We find that the lensed galaxy of Abell 2667 is a typical spiral galaxy with morphology similar to the structure of its counterparts at higher redshift z \sim 2 .
The surface brightness of the reconstructed source galaxy in the z _ { 850 } band reveals the central surface brightness I ( 0 ) = 20.28 \pm 0.22 mag arcsec ^ { -2 } and the characteristic radius r _ { s } = 2.01 \pm 0.16 kpc at redshift z \sim 1 .
The morphological reconstruction in different bands shows obvious negative radial color gradients for this galaxy .
Moreover , the redder central bulge tends to contain a metal-rich stellar population , rather than being heavily reddened by dust due to high and patchy obscuration .
We analyze the VIMOS/IFU spectroscopic data and find that , in the given wavelength range ( \sim 1800 - 3200 Ã ) , the combined arc spectrum of the source galaxy is characterized by a strong continuum emission with strong UV absorption lines ( FeII and MgII ) and shows the features of a typical starburst Wolf-Rayet galaxy NGC5253 .
More specifically , we have measured the EWs of FeII and MgII lines in the Abell 2667 spectrum , and obtained similar values for the same wavelength interval of the NGC5253 spectrum .
Marginal evidence for CIII ] 1909 emission at the edge of the grism range further confirms our expectation .
