MAHALO Deep Cluster Survey I. Accelerated and enhanced galaxy formation in the densest regions of a protocluster at z=2.5

Rhythm Shimakawa, Tadayuki Kodama, Masao Hayashi +6

We carried out deep H narrowband imaging with 10 hours net integrations towards the young protocluster, USS1558003 at with the Subaru Telescope. This system is compo…

The interstellar medium in [OIII]-selected star-forming galaxies at

Tomoko L. Suzuki, Tadayuki Kodama, Masato Onodera +11

We present new results from near-infrared spectroscopy with Keck/MOSFIRE of [OIII]-selected galaxies at . With our and -band spectra, we investigate the interstell…

A universal correlation between star-formation activity and molecular gas properties across environments

Shuhei Koyama, Yusei Koyama, Takuji Yamashita +10

We present the molecular gas mass fraction () and star-formation efficiency (SFE) of local galaxies on the basis of our new CO() observations with the Nobeya…

Evolutionary phases of gas-rich galaxies in a galaxy cluster at z=1.46

Masao Hayashi, Tadayuki Kodama, Kotaro Kohno +7

We report a survey of molecular gas in galaxies in the XMMXCS J2215.9-1738 cluster at . We have detected emission lines from 17 galaxies within a radius of from t…

Identification of variability in recent star formation histories of local galaxies based on H/UV ratio

Rhythm Shimakawa, Yusei Koyama, J. Xavier Prochaska +3

Because the timescale of H emission (several tens of Myr) following star formation is significantly shorter than that of UV radiation (a few hundred Myr), the H/UV flux ratio…

The nature of H-selected galaxies along the large-scale structure at z=0.4 revealed by Subaru Hyper Suprime-Cam survey

Yusei Koyama, Masao Hayashi, Masayuki Tanaka +13

We present the environmental dependence of colour, stellar mass, and star formation (SF) activity in H-alpha-selected galaxies along the large-scale structure at z=0.4 hosting twin…

A 16 deg survey of emission-line galaxies at z<1.5 in HSC-SSP PDR1

Masao Hayashi, Masayuki Tanaka, Rhythm Shimakawa +15

We present initial results from the Subaru Strategic Program (SSP) with Hyper Suprime-Cam (HSC) on a comprehensive survey of emission-line galaxies at z<1.5 based on narrowband (NB…

Rotating starburst cores in massive galaxies at z=2.5

Ken-ichi Tadaki, Tadayuki Kodama, Erica J. Nelson +21

We present spatially resolved ALMA observations of the CO J=3-2 emission line in two massive galaxies at z=2.5 on the star-forming main sequence. Both galaxies have compact dusty s…

Direct evidence for Ly depletion in the protocluster core

Rhythm Shimakawa, Tadayuki Kodama, Masao Hayashi +8

We have carried out a panoramic Ly narrowband imaging with Suprime-Cam on Subaru towards the known protocluster USS1558--003 at . Our previous narrowband imaging at near…
