ALMA observations towards M83 reveal N2H+ tracing dense gas
Nanase Harada, Yuri Nishimura, Toshiki Saito +6
Galactic observations have shown that N2H+ intensities preferentially trace star-forming dense molecular gas compared with HCN or HCO+, which are conventionally used as dense-gas t…
Spectrally and spatially resolved (sub)millimeter HCN-to-HCO flux ratios in nearby ultraluminous infrared galaxies
Masatoshi Imanishi, Yuri Nishimura, Shunsuke Baba +2
We present the results of our investigations of spectrally and spatially resolved (sub)millimeter HCN-to-HCO flux ratios at J=2-1, J=3-2, and/or J=4-3 in 18 nearby ( 0.1…
ATT12: The Antarctic 12-m Terahertz Telescope for Studies of Dusty Galaxies. I. Instrument Sensitivity and Science Forecasts
Koki Wakasugi, Takuya Hashimoto, Nario Kuno +13
We present a feasibility study of the Antarctic 12m Terahertz Telescope (ATT12), a next-generation facility to be constructed at New Dome Fuji in Antarctica, designed to open up th…
Components of star formation in NGC 253 : Non-negative Matrix Factorization Analysis with the ALCHEMI integrated intensity images
Ryo Kishikawa, Nanase Harada, Toshiki Saito +12
It is essential to examine the physical or chemical properties of molecular gas in starburst galaxies to reveal the underlying mechanisms characterizing starbursts. We used non-neg…
The fountain of the luminous infrared galaxy Zw049.057 as traced by its OH megamaser
Boy Lankhaar, Susanne Aalto, Clare Wethers +15
High resolution (0."037-0."13 [10-35 pc]) e-MERLIN ( cm) and (0."024 [6.5 pc]) ALMA ( mm) observations have been used to image OH (hydroxyl) and HCO (formald…
ALMA Lensing Cluster Survey: Physical characterization of near-infrared-dark intrinsically faint ALMA sources at z=2-4
Akiyoshi Tsujita, Kotaro Kohno, Shuo Huang +33
We present results from Atacama Large Millimeter/submillimeter Array (ALMA) spectral line-scan observations at 3-mm and 2-mm bands of three near-infrared-dark (NIR-dark) galaxies b…
A temperature or FUV tracer? The HNC/HCN ratio in M83 on the GMC scale
Nanase Harada, Toshiki Saito, Yuri Nishimura +2
The HNC/HCN ratio is observationally known as a thermometer in Galactic interstellar molecular clouds. A recent study has alternatively suggested that the HNC/HCN ratio is affected…
Physical Properties of the Southwest Outflow Streamer in the Starburst Galaxy NGC 253 with ALCHEMI
Min Bao, Nanase Harada, Kotaro Kohno +19
The physical properties of galactic molecular outflows are important as they could constrain outflow formation mechanisms. We study the properties of the southwest (SW) outflow str…
The ALCHEMI atlas: principal component analysis reveals starburst evolution in NGC 253
Nanase Harada, David S. Meier, Sergio Martín +24
Molecular lines are powerful diagnostics of the physical and chemical properties of the interstellar medium (ISM). These ISM properties, which affect future star formation, are exp…
SERENADE II: An ALMA Multi-Band Dust-Continuum Analysis of 28 Galaxies at and the Physical Origin of the Dust Temperature Evolution
Ikki Mitsuhashi, Yuichi Harikane, Franz E. Bauer +14
We present an analysis of ALMA multi-band dust-continuum observations for 28 spectroscopically-confirmed bright Lyman-break galaxies at . Our sample consists of 11 galaxies…
Volume density structure of the NGC253 CMZ through ALCHEMI excitation analysis
Kunihiko Tanaka, Jeffrey G. Mangum, Serena Viti +21
We present a spatially-resolved excitation analysis for the central molecular zone (CMZ) of the starburst galaxy NGC 253 using the data from the ALMA Large program ALCHEMI, whereby…
