Do old globular clusters in low mass galaxies disprove modified gravity?
Michal Bílek, Hongsheng Zhao, Benoit Famaey +6
The controversy "dark matter vs. modified gravity" constitutes a major topic of discussion. It was proposed that dynamical friction could be used to discriminate between the two al…

We present new ALMA observations of the CO(3-2) transition and 854micron continuum at 0.06-0.3" resolution, together with new VLT/SINFONI observations of NGC7172. This is a luminou…
Gas, dust, and the CO-to-molecular gas conversion factor in low-metallicity starbursts
L. K. Hunt, F. Belfiore, F. Lelli +19
The factor relating CO emission to molecular hydrogen column density, XCO, is still subject to uncertainty, in particular at low metallicity. Here, to quantify XCO at two different…
Cosmo-tomography toward PKS1830-211: Variability of the quasar and of its foreground molecular absorption monitored with ALMA
S. Muller, I. Marti-Vidal, F. Combes +7
Time variability of astronomical sources provides crude information on their typical size and on the implied physical mechanisms. PKS1830-211 is a remarkable radio-bright lensed qu…
Star forming brightest cluster galaxies at in KiDS. Further studies of cold gas and stellar properties

Brightest cluster galaxies (BCGs) are among the most massive galaxies in the Universe. Their star formation (SF) history and stellar mass assembly are debated. Recent studies sugge…
SKA Science Data Challenge 2: analysis and results
P. Hartley, A. Bonaldi, R. Braun +105
The Square Kilometre Array Observatory (SKAO) will explore the radio sky to new depths in order to conduct transformational science. SKAO data products made available to astronomer…
Jet-induced molecular gas excitation and turbulence in the Teacup

Black hole and galaxy co-evolution in radio-loud AGN at z ~ 0.3-4
R. Poitevineau, G. Castignani, F. Combes
There exists a well known relation between the mass of the supermassive black hole (SMBH) in the center of galaxies and their bulge mass or central velocity dispersion. This sugges…

Does absorption against AGN reveal supermassive black hole accretion?
Tom Rose, B. R. McNamara, F. Combes +7
Galaxies often contain large reservoirs of molecular gas which shape their evolution. This can be through cooling of the gas -- which leads to star formation, or accretion onto the…
