    Research Interests and achievementt

    My research encompasses a galaxy evolution and observational cosmology. My selected past achievements include:

    ● Detected the integrated Sachs-Wolfe effect (expansion of the Universe) by

    cross-correlating WISE and WMAP at 3.1σ significance (most significant

    from a single galaxy map). (Goto et al. 2011d)

    ● Discovered one of the highest redshift QSOs at z6 to investigate the reionization

    process of the early Universe (Goto 2006).

    ● Performed the Gunn-Peterson test with a QSO at z=6.4 and found a 200 Mpc

    long dark gap (Goto et al 2011c).

    ● Discovered the most distant Lyα blob around a QSO and its host galaxy at z=6.4 (Goto et al.2009,2011e)

    Revealed dust-hidden cosmic star formation history at 0<z<2.2 more

    reliably than Spitzer by taking advantage of the AKARI space telescope's

    continuous mid-IR filters (Goto et al. 2010a,b,2011a,b).

    ● Found galaxy clusters to z 1.7 using a new technique using the AKARI's 4μm

    filter (Goto et al. 2008c).

    ● A creation of a catalog of 4,000 galaxy clusters (which was one of the

    largest) (Goto et al. 2002a)

    ● Revealed the environmental dependence of morphological and spectral

    evolution of galaxies with unprecedented statistical accuracy (Goto et al.


    ● Solved the 20-year-old mystery on the physical origin of post-starburst(E+A)

    galaxies (Goto et al. 2003d,2004,2005a)

    ● Found evidence of downsizing galaxy evolution using a HST/ACS cluster

    survey at z 1 (Goto et al. 2005b)
