A FUV and optical study of star formation in closely interacting galaxies: star forming rings, tidal arms and nuclear outflows

Jyoti Yadav, Mousumi Das, Sudhanshu Barway +1

We present a study of the morphology of star formation and the associated nuclear activity in a sample of 8 closely interacting southern galaxies, which are in different stages of…

The oblateness of dark matter halos of nearby galaxies and its correlation with gas mass fractions

Mousumi Das, Roger Ianjamasimanana, Stacy McGaugh +2

We present a method to measure the the oblateness parameter q of the dark matter halos of gas rich galaxies that have extended HI disks. We have applied our model to a sample of 20…

Dark Matter Halo Spin of the Dwarf Galaxy UGC 5288: Insights from Observations, N-body and Cosmological Simulations

Sioree Ansar, Sandeep K Kataria, Mousumi Das

Dark matter (DM) halo angular momentum is very challenging to determine from observations of galaxies. In this study, we present a new hybrid method of estimating the dimensionless…

Modelling Dark Matter Halo Spin using Observations and Simulations: application to UGC 5288

Sioree Ansar, Sandeep Kumar Kataria, Mousumi Das

Dark matter (DM) halo properties are extensively studied in cosmological simulations but are very challenging to estimate from observations. The DM halo density profile of observed…

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…
