ALMA reveals Strong [CII] emission in a galaxy embedded in a giant Lyman-alpha blob at z=3.1
Hideki Umehata, Yuichi Matsuda, Yoichi Tamura +21
We report the result from observations conducted with the Atacama Large Millimeter/submillimeter Array (ALMA) to detect [CII] 158 um fine structure line emission from galaxies embe…
Clustering of infrared-bright dust-obscured galaxies revealed by the Hyper Suprime-Cam and WISE
Yoshiki Toba, Tohru Nagao, Masaru Kajisawa +20
We present measurements of the clustering properties of a sample of infrared (IR) bright dust-obscured galaxies (DOGs). Combining 125 deg of wide and deep optical images obtain…
Outflow and metallicity in the broad-line region of low-redshift active galactic nuclei
Jaejin Shin, Tohru Nagao, Jong-Hak Woo
Outflows in active galactic nuclei (AGNs) are crucial to understand in investigating the co-evolution of supermassive black holes (SMBHs) and their host galaxies since outflows may…
Molecular gas on large circumgalactic scales at z=3.47
Michele Ginolfi, Roberto Maiolino, Tohru Nagao +9
We report ALMA observations of the most massive (star forming) galaxy in the redshift range 3<z<4 within the whole GOODS-S field. We detect a large elongated structure of molecular…
Revisiting the Completeness and the Luminosity Function in High-Redshift Low-Luminosity Quasar Surveys
Mana Niida, Tohru Nagao, Hiroyuki Ikeda +4
Recent studies have derived quasar luminosity functions (QLFs) at various redshifts. However, the faint side of the QLF at high redshifts is still too uncertain. An accurate estima…
A new quadruple gravitational lens from the Hyper Suprime-Cam Survey: the puzzle of HSC~J115252+004733
Anupreeta More, Chien-Hsiu Lee, Masamune Oguri +16
We report the serendipitous discovery of a quadruply lensed source at , HSC~J115252+004733, from the Hyper Suprime-Cam (HSC) Survey. The source is lensed by an earl…
