A CO detection in the off-plane region of the edge-on galaxy NGC 4565 with the Nobeyama 45-m telescope

Ren Matsusaka, Fumi Egusa, Fumiya Maeda +1

Understanding the cycling of interstellar medium (ISM) between the galactic plane and off-plane regions is crucial for tracing the evolution of disk galaxies. We present CO(…

Sub-kpc scale gas density histograms of the nearby barred spiral galaxy M83: Multi-component molecular gas structure reflecting the galactic environment

Ren Matsusaka, Toshihiro Handa, Fumi Egusa +8

We investigate the sub-kiloparsec (sub-kpc) molecular ISM structure and its relation to the galactic environment and star formation in the barred spiral galaxy M83 (NGC 5236). We e…

Spatially and Dynamically Extended Molecular Gas in Stephan's Quintet Revealed by ALMA CO(1-0) Total Power Mapping

Fumiya Maeda, Shinya Komugi, Kazuyuki Muraoka +15

We present ALMA Total Power CO(1-0) mapping of Stephan's Quintet (SQ), a prototypical compact galaxy group, with a uniform noise level at a spatial scale of ~25 kpc. These observat…

Sub-kpc scale gas density histogram of the Galactic molecular gas: a new statistical method to characterise galactic-scale gas structures

Ren Matsusaka, Toshihiro Handa, Yusuke Fujimoto +6

To understand physical properties of the interstellar medium (ISM) on various scales, we investigate it at parsec resolution on the kiloparsec scale. Here, we report on the sub-kpc…

Multi log-normal density structure in Cygnus-X molecular clouds: A fitting for N-PDF without power-law

Takeru Murase, Toshihiro Handa, Ren Matsusaka +6

We studied the H column density probability distribution function (N-PDF) based on molecular emission lines using the Nobeyama 45-m Cygnus X CO survey data. Using the DENDROGRA…

Ammonia mapping observations toward the Galactic massive star-forming region Sh 2-255 and Sh 2-257

Mikito Kohno, Toshihiro Omodaka, Toshihiro Handa +9

We performed NH and mapping observations toward the Galactic massive star-forming region Sh 2-255 and Sh 2-257 using the Nobeyama 45-m telescope as…
