HI absorption in MHONGOOSE -- Spin temperatures and cold neutral medium in nearby disk galaxies

W. J. G. de Blok, F. M. Maccagni, L. Chemin +7

Combined HI emission-absorption studies constrain the spin temperature and phase structure of the neutral atomic hydrogen interstellar medium (ISM), but have largely been limited t…

Outflowing shocked gas dominates the NIR H emission from the dual AGN NGC6240

J. Carlsen, C. Cicone, B. Hagedorn +10

[Abridged] We present a multi-line study of the kinematics of the molecular and ionised gas phases in the central 2 kpc of NGC6240, based on JWST/NIRSpec and ALMA observations. We…

A deep MeerKAT view of associated HI absorption in radio AGNs at intermediate redshift: Role of absorber geometry and conditions of the gas

Raffaella Morganti, Tom Oosterloo, Clive Tadhunter +1

We present MeerKAT observations searching for HI absorption in a sample of 17 powerful ( W Hz) radio sources at intermediate redshifts (

Not so-dark: High resolution HI imaging of J0139+4328 and identification of an optical counterpart

Barbara Å iljeg, Elizabeth A. K. Adams, Tom A. Oosterloo +4

Dark galaxies - systems rich in neutral hydrogen (HI) gas but with no stars - are a common prediction of numerous theoretical models and cosmological simulations. However, the uneq…

The inside-out quenching of the MHONGOOSE galaxy NGC 1371

S. Veronese, W. J. G. de Blok, F. Fraternali +5

We present the deepest 21-cm spectral line and 1.4 GHz broad-band continuum observations of nearby early-type spiral galaxy NGC 1371 as part of the MeerKAT HI Observations of Nearb…
