MIGHTEE-HI: Mass Models and Dark Matter properties
Anastasia A. Ponomareva, P. E. Mancera Piña, A. A. VÄrÄÅteanu +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…
Multi-resolution kinematic modelling of nearby galaxies: a demonstration using MHONGOOSE observations
B. R. Makinson, K. A. Oman, A. M. Swinbank
We present a novel method of combining kinematic models obtained at multiple spatial resolution levels in a self-consistent manner. The MHONGOOSE survey has mapped atomic hydrogen…
HI asymmetries in spatially resolved SIMBA galaxies
Nadine A. N. Hank, Marc A. W. Verheijen, Sarah-L. Blyth +4
We present a study of the neutral atomic hydrogen (HI) content of spatially resolved, low-redshift galaxies in the SIMBA cosmological simulations. We create synthetic HI data cubes…
Investigating the HI distribution and kinematics of ESO444-G084 and [KKS2000]23: New insights from the MHONGOOSE survey
Brenda Namumba, Roger Ianjamasimanana, Bärbel Koribalski +25
We present the HI distribution, kinematics, mass modeling, and disk stability of the dwarf irregular galaxies ESO444-G084 and [KKS2000]23 using high-resolution, high-sensitivity MH…
Star formation and stellar & AGN feedback in the absence of accretion, not gas stripping, set the quenching timescale in satellite galaxies
Anatolii I. Visser-Zadvornyi, Mary E. Carstairs, Kyle A. Oman +1
Observational measurements hint at a peak in the quenching timescale of satellite galaxies in groups and clusters as a function of their stellar masses at $M_{\star} \approx 10^{9.…
WALLABY pilot survey: properties of HI-selected dark sources and low surface brightness galaxies
T. O'Beirne, L. Staveley-Smith, V. A. Kilborn +13
We examine the optical counterparts of the 1829 neutral hydrogen (HI) detections in three pilot fields in the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) using dat…
