Cross-correlations between the CLAMATO Lyman-alpha forest and galaxies within the COSMOS field
Benjamin Zhang, Khee-Gan Lee, Andrei Cuceu +2
We compute the 3D cross-correlation between the absorption of the Lyman-alpha forest measured by the COSMOS Lyman-Alpha Mapping And Tomography Observations (CLAMATO) su…
Subaru Hyper Suprime-Cam excavates colossal over- and under-dense structures over 360 deg2 out to z=1
Rhythm Shimakawa, Yuichi Higuchi, Masato Shirasaki +8
Subaru Strategic Program with the Hyper-Suprime Cam (HSC-SSP) has proven to be successful with its extremely-wide area coverage in past years. Taking advantages of this feature, we…
On the Diffuse Lyman-alpha Halo Around Lyman-alpha Emitting Galaxies
Ethan Lake, Zheng Zheng, Renyue Cen +3
Ly photons scattered by neutral hydrogen atoms in the circumgalactic media or produced in the halos of star-forming galaxies are expected to lead to extended Ly emission arou…
Sensitivity for 21cm Bispectrum from Epoch of Reionization
Shintaro Yoshiura, Hayato Shimabukuro, Keitaro Takahashi +3
The 21cm line brightness temperature brings rich information about Epoch of Reionizaton (EoR) and high- universe (Cosmic Dawn and Dark Age). While the power spectrum is a useful…
Diffuse Lyman-alpha Halos around Galaxies at z=2.2-6.6: Implications for Galaxy Formation and Cosmic Reionization
Rieko Momose, Masami Ouchi, Kimihiko Nakajima +6
We present diffuse Lyman-alpha halos (LAHs) identified in the composite Subaru narrowband images of 100-3600 Lyman-alpha emitters (LAEs) at z=2.2, 3.1, 3.7, 5.7, and 6.6. First, we…
Accelerated Evolution of Ly Luminosity Function at Revealed by the Subaru Ultra-Deep Survey for Ly Emitters at
Akira Konno, Masami Ouchi, Yoshiaki Ono +8
We present the ultra-deep Subaru narrowband imaging survey for Lya emitters (LAEs) at in SXDS and COSMOS fields with a total integration time of 106 hours. Exploiting our n…
Star Formation On Sub-kpc Scale Triggered By Non-linear Processes In Nearby Spiral Galaxies
Rieko Momose, Jin Koda, Robert C. Kennicutt +8
We report a super-linear correlation for the star formation law based on new CO(=1-0) data from the CARMA and NOBEYAMA Nearby-galaxies (CANON) CO survey. The sample includes 10…
First Systematic Search for Oxygen-Line Blobs at High Redshift: Uncovering AGN Feedback and Star-Formation Quenching
Suraphong Yuma, Masami Ouchi, Alyssa B. Drake +8
We present the first systematic search for extended metal-line [OII]λλ3726,3729 nebulae, or [OII] blobs (OIIBs), at z=1.2 using deep narrowband imaging with a survey volume of 1.9x…
An Intensely Star-Forming Galaxy at z~7 with Low Dust and Metal Content Revealed by Deep ALMA and HST Observations
Masami Ouchi, Richard Ellis, Yoshiaki Ono +10
We report deep ALMA observations complemented with associated HST imaging for a luminous (m_uv=25) galaxy, `Himiko', at a redshift z=6.595. The galaxy is remarkable for its high st…
Physical Conditions in Molecular Clouds in the Arm and Interarm Regions of M51
J. Koda, N. Scoville, T. Hasegawa +10
We report systematic variations in the CO(2-1)/CO(1-0) line ratio (R) in M51. The ratio shows clear evidence for the evolution of molecular gas from the upstream interarm regions,…
Resolved Measurements of Xco in NGC 6946
Jennifer Donovan Meyer, Jin Koda, Rieko Momose +9
We present the largest sample to date of giant molecular clouds (GMCs) in a substantial spiral galaxy other than the Milky Way. We map the distribution of molecular gas with high r…
The Super-linear Slope of the Spatially-Resolved Star Formation Law in NGC 3521 and NGC 5194 (M51a)
Guilin Liu, Jin Koda, Daniela Calzetti +2
We have conducted interferometric observations with CARMA and an OTF mapping with the 45-m telescope at NRO in the CO (J=1-0) emission line of NGC 3521. Combining these new data, t…
Star formation efficiency in the Barred Spiral Galaxy NGC 4303
Rieko Momose, Sachiko K. Okumura, Jin Koda +1
We present new CO(J=1-0) observations of the barred galaxy NGC 4303 using the Nobeyama 45m telescope (NRO45) and the Combined Array for Research in Millimeter-wave Astronomy…
