The corotation gap in the Galactic H i distribution
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
We used the H i data from the LAB Survey to map the ring-shaped gap in H i density that lies slightly outside the solar circle. Adopting R(0) = 7.5 kpc, we find an average gap radius of 8.3 kpc and an average gap width of ...
Integral-Field Stellar and Ionized Gas Kinematics of Peculiar Virgo Cluster Spiral Galaxies
(American Astronomical Society, 2015)
We present the stellar and ionized gas kinematics of 13 bright peculiar Virgo cluster galaxies observed with the
DensePak Integral Field Unit at the WIYN 3.5m telescope in order to look for kinematic evidence that ...
Accretion of galaxy groups into galaxy clusters
(Wiley Blackwell Publishing, Inc, 2020-11)
We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼1014 M from the cosmological hydrodynamical simulation Illustris and follow their ...
