Advancing extragalactic spectral line studies with the Square Kilometre Array Observatory
Jacco Th. van Loon, Viviana Casasola, Manuela Bischetti +6
We present an overview of the Square Kilometre Array Observatory (SKAO) science potential in the area of extragalactic spectral lines besides 21-cm neutral hydrogen. It highlights…
HI 21-cm absorption in low- and high-excitation radio-loud AGNs at from MALS
P. P. Deka, N. Gupta, J-. K. Krogager +5
We present results from a search of cold neutral gas associated with radio-loud active galactic nuclei (AGNs) at using HI 21-cm absorption measurements from the MeerKAT A…
The MeerKAT Absorption Line Survey (MALS) data release 3: Cold atomic gas associated with the Milky Way
N. Gupta, J. Kerp, S. A. Balashev +15
We present results of a blind search for Galactic HI 21-cm absorption lines toward 19130 radio sources, using 390 pointings of MALS, each pointing centered on a source brighter tha…
LeMMINGs. Multi-wavelength constraints on the co-existence of nuclear star clusters and AGN in nucleated galaxies
B. T. Dullo, J. H. Knapen, R. D. Baldi +16
[Abridged] The relation between nuclear star clusters (NSCs) and the growth of the central SMBHs, as well as their connection to the properties of the host galaxies, is crucial for…
MHONGOOSE -- A MeerKAT Nearby Galaxy HI Survey
W. J. G. de Blok, J. Healy, F. M. Maccagni +57
The MHONGOOSE (MeerKAT HI Observations of Nearby Galactic Objects: Observing Southern Emitters) survey maps the distribution and kinematics of the neutral atomic hydrogen (HI) gas…
MALS discovery of a rare HI 21-cm absorber at : origin of the absorbing gas in powerful AGN
P. P. Deka, N. Gupta, H. W. Chen +14
We report a new, rare detection of HI 21-cm absorption associated with a quasar (only six known at ) here towards J2339-5523 at = 1.3531, discovered through the Mee…
