HI in the Outskirts of Nearby Galaxies
A. Bosma
The HI in disk galaxies frequently extends beyond the optical image, and can trace the dark matter there. I briefly highlight the history of high spatial resolution HI imaging, the…
Constraining the dark matter content of NGC 1291 using hydrodynamic gas response simulations
F. Fragkoudi, E. Athanassoula, A. Bosma
We present a pilot study on the nearby massive barred galaxy NGC 1291, in which we use dynamical modelling to constrain the disc mass-to-light ratio (M/L), thus breaking the degene…
The (dark) halo-to-stellar mass ratio in the Spitzer Survey of Stellar Structure in Galaxies (SG)
Simón Díaz-García, Heikki Salo, Eija Laurikainen +1
We use 3.6 m photometry for 1154 disk galaxies () in the Spitzer Survey of Stellar Structure in Galaxies (SG, Sheth et al. 2010) to obtain the stellar compon…
Detailed HI kinematics of Tully-Fisher calibrator galaxies
Anastasia A. Ponomareva, Marc A. W. Verheijen, Albert Bosma
We present spatially-resolved HI kinematics of 32 spiral galaxies which have Cepheid or/and Tip of the Red Giant Branch distances, and define a calibrator sample for the Tully-Fish…
Evidence of Bar-induced Secular Evolution in the Inner Regions of Stellar Discs in Galaxies: What Shapes Disc Galaxies?
Taehyun Kim, Dimitri A. Gadotti, E. Athanassoula +3
We present evidence of bar-induced secular evolution in galactic discs using 3.6 images of nearby galaxies from the Spitzer Survey of Stellar Structure in Galaxies (S4G). We…
A close look at secular evolution: Boxy/peanut bulges reduce gas inflow to the central kiloparsec
F. Fragkoudi, E. Athanassoula, A. Bosma
In this letter we investigate the effect of boxy/peanut (b/p) bulges on bar-induced gas inflow to the central kiloparsec, which plays a crucial role on the evolution of disc galaxi…
