What powers the starburst activity of NGC 1068? Star-driven gravitational instabilities caught in the act
Alessandro B. Romeo, Kambiz Fathi
We explore the role that gravitational instability plays in NGC 1068, a nearby Seyfert galaxy that exhibits unusually vigorous starburst activity. For this purpose, we use the Rome…
Submillimeter-HCN Diagram for an Energy Diagnostics in the Centers of Galaxies
Takuma Izumi, Kotaro Kohno, Susanne Aalto +16
Compiling data from literature and the ALMA archive, we show enhanced HCN(4-3)/HCO(4-3) and/or HCN(4-3)/CS(7-6) integrated intensity ratios in circumnuclear molecular gas aroun…
ALMA Observations of the Submillimeter Dense Molecular Gas Tracers in the Luminous Type-1 Active Nucleus of NGC 7469
Takuma Izumi, Kotaro Kohno, Susanne Aalto +30
We present ALMA Cycle 1 observations of the central kpc region of the luminous type-1 Seyfert galaxy NGC 7469 with unprecedented high resolution (0.5 0.4 = 165 pc $\…
The OH-streamer in Sgr A revisited: analysis of hydroxyl absorption within 10 pc from the Galactic centre
Roland Karlsson, Aage Sandqvist, Kambiz Fathi +1
We study the structure and kinematics of the OH-streamer and the +80 km/s cloud and their interactions with the circumnuclear disk (CND) and with other molecular clouds in the vici…
Kinematics of Haro11 - the miniature Antennae
Göran Östlin, Thomas Marquart, Robert Cumming +5
(abridged) Luminous blue compact galaxies are among the most active galaxies in the local universe in terms of their star formation rate per unit mass. They may be seen as the loca…
Local instability signatures in ALMA observations of dense gas in NGC7469
Kambiz Fathi, Takuma Izumi, Alessandro B. Romeo +11
We present an unprecedented measurement of the disc stability and local instability scales in the luminous infrared Seyfert 1 host, NGC7469, based on ALMA observations of dense gas…
