Exhaustion of the gas next to M31's supermassive black hole
Anne-Laure Melchior, Francoise Combes
New observations performed at IRAM Plateau de Bure reveal the absence of molecular gas next to Andromeda's black hole. We derived a 3 sigma upper limit on the molecular gas mass of…
Properties of the molecular gas in the fast outflow in the Seyfert galaxy IC 5063
Tom Oosterloo, J. B. Raymond Oonk, Raffaella Morganti +5
We present a detailed study of the molecular gas in the fast AGN-driven outflow in the nearby radio-loud Seyfert galaxy IC 5063. Using ALMA observations of a number of tracers (12C…
A CO Detection in a Brightest Cluster Galaxy
A. N. Vantyghem, B. R. McNamara, A. C. Edge +7
We present ALMA Cycle 4 observations of CO(1-0), CO(3-2), and CO(3-2) line emission in the brightest cluster galaxy of RXJ0821+0752. This is one of the first detections of $…
An Overview of the MHONGOOSE Survey: Observing Nearby Galaxies with MeerKAT
W. J. G. de Blok, E. A. K. Adams, P. Amram +65
MHONGOOSE is a deep survey of the neutral hydrogen distribution in a representative sample of 30 nearby disk and dwarf galaxies with HI masses from 10^6 to ~10^{11} M_sun, and lumi…
ALMA imaging of C2H emission in the disk of NGC1068
S. Garcia-Burillo, S. Viti, F. Combes +16
We study the feedback of star formation and nuclear activity on the chemistry of molecular gas in NGC1068, a nearby (D=14Mpc) Seyfert 2 barred galaxy, by analyzing if the abundance…
Close entrainment of massive molecular gas flows by radio bubbles in the central galaxy of Abell 1795
H. R. Russell, B. R. McNamara, A. C. Fabian +8
We present new ALMA observations tracing the morphology and velocity structure of the molecular gas in the central galaxy of the cluster Abell 1795. The molecular gas lies in two f…
AGN feedback and its quenching efficiency
F. Combes
In the last decade, observations have accumulated on gas outflows in galaxies, and in particular massive molecular ones. The mass outflow rate is estimated between 1-5 times the st…
The MeerKAT Absorption Line Survey (MALS)
N. Gupta, R. Srianand, W. Baan +41
Deep galaxy surveys have revealed that the global star formation rate (SFR) density in the Universe peaks at 1 < z < 2 and sharply declines towards z = 0. But a clear picture of th…
Secular evolution of Milky Way-type galaxies
F. Combes
The internal evolution of disk galaxies like the Milky Way are driven by non-axisymmetries (bars) and the implied angular momentum transfer of the matter; baryons are essentially d…
Detection of CH+, SH+, and their 13C- and 34S- isotopologues toward PKS1830-211
S. Muller, H. S. P. M"uller, J. H. Black +13
The z=0.89 molecular absorber toward PKS1830-211 provides us with the opportunity to probe the chemical and physical properties of the interstellar medium in the disk of a galaxy a…
Closing remarks and Outlook
F. Combes
Some highlights are given of the IAU Symposium 334, Rediscovering our Galaxy, held in Potsdam, in July 2017: from the first stars fossil records found in the halo, the carbon-enhan…
Molecular Gas Dominated 50 kpc Ram Pressure Stripped Tail of the Coma Galaxy D100
Pavel Jachym, Ming Sun, Jeffrey D. P. Kenney +6
We have discovered large amounts of molecular gas, as traced by CO emission, in the ram pressure stripped gas tail of the Coma cluster galaxy D100 (GMP 2910), out to large distance…
Luminous, pc-scale CO 6-5 emission in the obscured nucleus of NGC1377
S. Aalto, S. Muller, F. Costagliola +13
High resolution submm observations are important in probing the morphology, column density and dynamics of obscured active galactic nuclei (AGNs). With high resolution (0.06 x 0.05…
