The Thirty Millimeter Telescope
Yoshifusa Ita, Takashi Ichikawa, Hironori Tsutsui +11
A near-infrared telescope with an effective aperture diameter of thirty millimeters has been developed. The primary objective of the development is to observe northern bright stars…
The fate of a red nugget: In-situ star formation of satellites around a massive compact galaxy
Takahiro Morishita, Takashi Ichikawa
To study the accretion phase for local massive galaxies, we search accreting satellites around a massive compact galaxy (M_*~3.9x10^10Msun), spectroscopically confirmed (z_spec-1.9…
Noise Based Detection and Segmentation of Nebulous Objects
Mohammad Akhlaghi, Takashi Ichikawa
A noise-based non-parametric technique for detecting nebulous objects, for example, irregular or clumpy galaxies, and their structure in noise is introduced. "Noise-based" and "non…
From Diversity to Dichotomy, and Quenching: Milky-Way-Like and Massive-Galaxy Progenitors at 0.5<z<3.0
Takahiro Morishita, Takashi Ichikawa, Masafumi Noguchi +4
Using the HST/WFC3 and ACS multi-band imaging data taken in CANDELS and 3D-HST, we study the general properties and the diversity of the progenitors of the Milky Way (MWs) and loca…
NIR spectroscopic observation of massive galaxies in the protocluster at z = 3.09
Mariko Kubo, Toru Yamada, Takashi Ichikawa +3
We present the results of near-infrared spectroscopic observations of the -band selected candidate galaxies in the protocluster at in the SSA22 field. We observed 67 ca…
The evolution of galaxy size and morphology at z~0.5-3.0 in the GOODS-N region with HST/WFC3 data
Takahiro Morishita, Takashi Ichikawa, Masaru Kajisawa
We analyze the recent released HST/WFC3 IR images in the GOODS-N region to study the formation and evolution of Quiescent galaxies (QGs). After examining the reliability with artif…
