Deep HI observations of cold gas inflow and outflow
W. J. G. de Blok, D. B. Fisher, K. Tachihara +8
A major question in galaxy evolution is how galaxies acquire sufficient gas to sustain their star formation rates. HI observations with high angular resolution and sensitivity to v…
Head-tail molecular clouds falling onto the Milky Way disk
Mikito Kohno, Yasuo Fukui, Takahiro Hayakawa +13
We report discovery of two CO clouds which are likely falling down to the Galactic plane at more than km s. The clouds show head-tail distributions elongated perpendicu…
Giant molecular clouds and their Type classification in M74: Toward understanding star formation and cloud evolution
F. Demachi, Y. Fukui, R. I. Yamada +10
We investigated the giant molecular clouds (GMCs) in M74 (NGC 628), using data obtained from the PHANGS project. We applied the GMC Types according to the activity of star formatio…
A Young GMC Formed at the Interface of Two Colliding Supershells: Observations Meet Simulations
J. R. Dawson, E. Ntormousi, Y. Fukui +2
Dense, star-forming gas is believed to form at the stagnation points of large-scale ISM flows, but observational examples of this process in action are rare. We here present a gian…
Characterizing the structure of diffuse emission in Hi-GAL maps
D. Elia, F. Strafella, N. Schneider +18
We present a study of the structure of the Galactic interstellar medium through the Delta-variance technique, related to the power spectrum and the fractal properties of infrared/s…
Optically thick HI dominant in the local interstellar medium; an alternative interpretation to "dark gas"
Y. Fukui, K. Torii, T. Onishi +5
Dark gas in the interstellar medium (ISM) is believed to not be detectable either in CO or Hi radio emission, but it is detected by other means including gamma-rays, dust emission…
SPLASH: The Southern Parkes Large-Area Survey in Hydroxyl - First Science from the Pilot Region
J. R. Dawson, A. J. Walsh, P. A. Jones +20
SPLASH (the Southern Parkes Large-Area Survey in Hydroxyl) is a sensitive, unbiased and fully-sampled survey of the Southern Galactic Plane and Galactic Centre in all four ground-s…
Molecular Clouds Toward the Super Star Cluster NGC3603; Possible Evidence for a Cloud-Cloud Collision in Triggering the Cluster Formation
Yasuo Fukui, Akio Ohama, Naoki Hanaoka +17
We present new large field observations of molecular clouds with NANTEN2 toward the super star cluster NGC3603 in the transitions 12CO(J=2-1, J=1-0) and 13CO(J=2-1, J=1-0). We sugg…
The first Hi-GAL observations of the outer Galaxy: a look to star formation in the third Galactic quadrant in the longitude range 216.5 < l < 225.5
D. Elia, S. Molinari, Y. Fukui +17
We present the first Herschel PACS and SPIRE photometric observations in a portion of the outer Galaxy ( and $-2^{\circ} \lesssi…
Non-thermal X-rays and interstellar gas toward the γ-ray supernova remnant RX J1713.7-3946: Evidence for X-ray enhancement around CO and HI clumps
H. Sano, T. Tanaka, K. Torii +18
RX J1713.7-3946 is the most remarkable very-high-energy γ-ray supernova remnant which emits synchrotron X-rays without thermal features. We made a comparative study of CO, HI and X…
A Detailed Study of the Molecular and Atomic Gas Toward the γ-ray SNR RX J1713.7-3946: Spatial TeV γ-ray and ISM Gas Correspondence
Y. Fukui, H. Sano, J. Sato +14
RX J1713.73946 is the most remarkable TeV -ray SNR which emits -rays in the highest energy range. We made a new combined analysis of CO and \ion{H}{1} in the SNR and deriv…
