HI Galaxy Science with the SKA
Jing Wang, D. J. Pisano, Sarah Blyth +9
This chapter introduces the contributions of the HI galaxy science in this volume reviewing the latest developments and urgent questions in HI galaxy science, providing guiding pri…
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…
