Still alive and kicking: A significant outburst in changing-look AGN Mrk 1018
R. Brogan, M. Krumpe, D. Homan +13
Changing-look active galactic nuclei (CL-AGN) have been observed to change optical spectral type. Mrk 1018 is unique: first classified as a type 1.9 Seyfert galaxy, it transitioned…
Resolved Kennicutt-Schmidt law in two strongly lensed star-forming galaxies at redshift 1
David Nagy, Miroslava Dessauges-Zavadsky, Matteo Messa +4
We study the star formation rate (SFR) versus molecular gas mass () scaling relation from hundreds to thousands parsec scales in two strongly lensed galaxies at red…
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…
ViCTORIA project: MeerKAT HI observations of the ram pressure stripped galaxy NGC 4523
A. Boselli, P. Serra, F. de Gasperin +22
We present the first results of a 21 cm HI line pilot observation carried out with MeerKAT in preparation for the ViCTORIA project, an untargeted survey of the Virgo galaxy cluster…
X-ray Cavity Dynamics and their Role in the Gas Precipitation in Planck Sunyaev-Zeldovich (SZ) Selected Clusters
V. Olivares, Y. Su, W. Forman +7
We study active galactic nucleus (AGN) feedback in nearby (z<0.35) galaxy clusters from the Planck Sunyaev-Zeldovich (SZ) sample using Chandra observations. This nearly unbiased ma…
Asymmetries in random motions of neutral Hydrogen gas in spiral galaxies
P. Adamczyk, P. Amram, L. Chemin +4
(Abridged). It has been recently shown that random motions of the neutral Hydrogen gas of the Triangulum galaxy (M33) exhibit a bisymmetric perturbation which is aligned with the m…
AGN feedback in action in the molecular gas ring of the Seyfert galaxy NGC7172
A. Alonso-Herrero, S. Garcia-Burillo, M. Pereira-Santaella +14
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
G. Castignani, M. Radovich, F. Combes +10
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
A. Audibert, C. Ramos Almeida, S. García-Burillo +6
In order to investigate the impact of radio jets on the interstellar medium (ISM) of galaxies hosting active galactic nuclei (AGN), we present subarcsecond resolution Atacama Large…
Proximate molecular quasar absorbers: Chemical enrichment and kinematics of the neutral gas
P. Noterdaeme, S. Balashev, R. Cuellar +7
Proximate molecular quasar absorbers (PH2) are an intriguing population of absorption systems recently uncovered through strong H2 absorption at small velocity separation from the…
The MeerKAT Absorption Line Survey: Homogeneous continuum catalogues towards a measurement of the cosmic radio dipole
J. D. Wagenveld, H. -R. Klöckner, N. Gupta +21
The number counts of homogeneous samples of radio sources are a tried and true method of probing the large scale structure of the Universe, as most radio sources outside the galact…
PKS1413+135: OH and HI at z = 0.247 with MeerKAT
F. Combes, N. Gupta, S. Muller +13
The BL Lac PKS 1413+135 was observed by the Large Survey Project "MeerKAT Absorption Line Survey" (MALS) in the L-band, at 1139 MHz and 1293-1379 MHz, targeting the HI and OH lines…
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…
