Scientific paper

We present the multi-band images of the Ophiuchus molecular cloud region to investigate the physical properties of dust. Based on the far-ultraviolet (FUV; 1370 - 1670 A) image, observed with the SPEAR imaging spectrograph, we generate a model that gives the properties of the dust grains (such as albedo and asymmetry factor) in the cloud. With the obtained FUV intensity map, we combine the Spitzer MIPS and the Akari FIS observations to produce a dust temperature map and a far-IR (FIR) dust opacity map for further analysis of dust evolution.
