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…
The Gamma Ray Origin in RXJ0852.0-4622 Quantifying the Hadronic and Leptonic Components: Further Evidence for the Cosmic Ray Acceleration in Young Shell-type SNRs
Yasuo Fukui, Maki Aruga, Hidetoshi Sano +5
Fukui et al. (2021) quantified the hadronic and leptonic gamma rays in the young TeV gamma ray shell-type supernova remnant (SNR) RXJ1713.7-3946 (RXJ1713), and demonstrated that th…
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…
ALMA CO Observations of the Gamma-Ray Supernova Remnant RX J1713.7-3946: Discovery of Shocked Molecular Cloudlets and Filaments at 0.01 pc scales
H. Sano, T. Inoue, K. Tokuda +14
RX J1713.7-3946 is a unique core-collapse SNR that emits bright TeV gamma-rays and synchrotron X-rays caused by cosmic rays, in addition to interactions with interstellar gas cloud…
A detailed study of the interstellar protons toward the TeV -ray SNR RX J0852.04622 (G266.21.2, Vela Jr.); a third case of the -rays and ISM spatial correspondence
Y. Fukui, H. Sano, J. Sato +18
We present a new analysis of the interstellar protons toward the TeV -ray SNR RX J0852.04622 (G266.21.2, Vela Jr.). We used the NANTEN2 CO( = 1-0) and ATCA & Par…
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…
Investigation of Dense Gas Towards Relativistic Outflow Sources
J. Hawkes, G. Rowell, B. Dawson +10
We probe the interstellar medium towards the objects Circinus X-1, a low-mass X-ray binary with relativistic jets; and the highly energetic Westerlund 2 stellar cluster, which is l…
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…
Detailed Investigation of the Gamma-Ray Emission in the Vicinity of SNR W28 with FERMI-LAT
Yoshitaka Hanabata, Hideaki Katagiri, John W. Hewitt +9
We present a detailed investigation of the -ray emission in the vicinity of the supernova remnant (SNR) W28 (G6.40.1) observed by the Large Area Telescope (LAT) onboard the F…
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…
A detailed study of non-thermal X-ray properties and interstellar gas toward the γ-ray supernova remnant RX J1713.7-3946
