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…

MIGHTEE-\HI: Possible interactions with the galaxy NGC~895

Brenda Namumba, Javier Román, Jesus Falcon Barroso +29

The transformation and evolution of a galaxy is strongly influenced by interactions with its environment. Neutral hydrogen (\HI) is an excellent way to trace these interactions. He…

Estimating the Oblateness Of Dark Matter Halos Using Neutral Hydrogen Velocity Dispersion

Mousumi Das, Roger Ianjamasimanana, Stacy S. McGaugh +2

We derive the oblateness parameter q of the dark matter halo of a sample of gas rich, face-on disk galaxies. We have assumed that the halos are triaxial in shape but their axes in…
