AbstractA study of [S iii]λλ9096, 9532 emitters at z = 1.34 and 1.23 is presented using our deep narrow-band H 2 S 1 (centered at 2.13 μm) imaging survey of the Extended Chandra Deep Field South (ECDFS). We combine our data with multi-wavelength data of ECDFS to build up spectral energy distributions (SEDs) from the U to the K s-band for emitter candidates selected with strong excess in H 2 S 1 - K s and derive photometric redshifts, line luminosities, stellar masses and extinction. A sample of 14 [S iii] emitters are identified with H 2 S 1 < 22.8 and K s < 24.8 (AB) over 381 arcmin2 area, having [S iii] line luminosity L [SIII] =∼ 1041.5-42.6 erg s-1. None of the [S iii] emitters is found to have X-ray counterpart in the deepest Chandra 4Ms observation, suggesting that they are unlikely powered by AGNs. The HST/ACS F606W and HST/WFC3 F160W images show their rest-frame UV and optical morphologies. About half of the [S iii] emitters are mergers and at least one third are disk-type galaxies. Nearly all [S iii] emitters exhibit a prominent Balmer break in their SEDs, indicating the presence of a significant post-starburst component. Taken together, our results imply that both shock heating in post-starburst and photoionization caused by young massive stars are likely to excite strong [S iii] emission lines. We conclude that the [S iii] emitters in our sample are dominated by star-forming galaxies (SFGs) with stellar mass 8.7 < log(M/M aˆSˇ™) < 9.9. © 2013 Science China Press and Springer-Verlag Berlin Heidelberg.(56 refs) Main heading: Stars
