AGN Feeding & Feedback Over the Galactic Scales
Filippo M. Maccagni, Vincenzo Mainieri, Isabella Prandoni +8
Active Galactic Nuclei (AGN) are key drivers of galaxy evolution, triggered by cold gas accreting onto a super-massive black hole. However, the processes regulating this gas accret…
Deep HI observations of cold gas inflow and outflow
W. J. G. de Blok, D. B. Fisher, K. Tachihara +8
A major question in galaxy evolution is how galaxies acquire sufficient gas to sustain their star formation rates. HI observations with high angular resolution and sensitivity to v…
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…
The ultra-deep HI radial profiles of late-type galaxies from MHONGOOSE
S. Veronese, W. J. G. de Blok, E. Brinks +4
Galaxy discs have a finite extent, yet how and where their neutral atomic hydrogen (HI) components end is not fully understood. The existence of a break in the HI disc at column de…
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…
FEASTS and MHONGOOSE: HI Column Density Distribution at for
Jing Wang, Xuchen Lin, Ze-Zhong Liang +24
We present the first HI column density distribution function, , extending down to . This was derived from high-s…
