MIGHTEE-HI: Mass Models and Dark Matter properties

Anastasia A. Ponomareva, P. E. Mancera Piña, A. A. Vărăşteanu +17

Measuring galaxy rotation curves is critical for inferring the properties of dark-matter haloes in the Lambda Cold Dark Matter (CDM) paradigm. We present HI rotation curves and…

The AGN fuelling/feedback cycle in nearby radio galaxies III. 3D relative orientations of radio jets and CO discs and their interaction

I. Ruffa, R. A. Laing, I. Prandoni +4

This is the third paper of a series exploring the multi-frequency properties of a sample of eleven nearby low-excitation radio galaxies (LERGs) in the southern sky. We are conducti…

Molecular gas kinematics in local early-type galaxies with ALMA

I. Ruffa, T. A. Davis

Local early-type galaxies (ETGs) are mostly populated by old stars, with little or no recent star formation activity. For this reason, they have historically been believed to be es…

The AGN fuelling/feedback cycle in nearby radio galaxies - V. The cold atomic gas of NGC 3100 and its group

F. M. Maccagni, I. Ruffa, A. Loni +6

We present Australia Compact Telescope Array (ATCA) 21-cm observations of the nearby low-excitation radio galaxy (LERG) NGC 3100. This is the brightest galaxy of a loose group and…

MIGHTEE-HI: deep spectral line observations of the COSMOS field

I. Heywood, A. A. Ponomareva, N. Maddox +16

The MIGHTEE survey utilises the South African MeerKAT radio telescope to observe four extragalactic deep fields, with the aim of advancing our understanding of the formation and ev…

CO in the ALMA Radio-Source Catalogue (ARC): the molecular gas content of radio galaxies as a function of redshift

A. Audibert, K. M. Dasyra, M. Papachristou +6

To evaluate the role of radio activity in galaxy evolution, we designed a large archival CO survey of radio galaxies (RGs) to determine their molecular gas masses at different epoc…
