Star Forming Molecular Gas in Early Stage Mergers
[Abstract]
While the simulations have predicted a number of intriguing aspects of the gas response during the early stages of a galaxy collision, only a handful of observational tests exist in literature so far. We performed observation of early stages galaxies with Nobeyama45m CO(1-0) and ASTE10m CO(3-2). An extensive survey of molecular gas along the complete merger sequence will finally allow us a detailed comparison with the predictions from numerical simulations.

Rapid dust production in Hα-8μm-selected galaxies at z=2
[Abstract]
I present results on the dust obscuration of star-burst galaxies at z=2 selected by MIPS/Spitzer and MOIRCS/Subaru, towards on-going programs with ALMA. Thanks to our past narrow-band imaging survey (Mahalo-Subaru), we have a large sample of Hα-selected star-forming galaxies. By combining them with MIPS 24um data, we probed ~50 dusty galaxies with IR luminosities above 5E11 Lsun. Since those also have spatially-resolved rest-UV image taken by Hubble Space Telescope, we can study morphological dependence of dust properties (IRX=IR/UV). Our preliminary results show that for a given UV slope, “UV-saturated” galaxies have more heavily-obscured UV structures, which directly indicates that dust covering fraction increase rapidly than intrinsic UV luminosity as suggested by Reddy et al. 2010. Moreover, such highly-obscured galaxies tend to have high equivalent widths of Hα emission, which is also good agreement with dust properties of massive galaxies at low redshift (Koyama et al. 2015).
