The stellar halo of isolated central galaxies in the Hyper Suprime-Cam imaging survey
Wenting Wang, Jiaxin Han, Alessandro Sonnenfeld +14
We study the faint stellar halo of isolated central galaxies, by stacking galaxy images in the HSC survey and accounting for the residual sky background sampled with random points.…
Kinematics of cluster galaxies and their relation to galaxy evolution
Susmita Adhikari, Neal Dalal, Surhud More +1
We study the kinematics of galaxies within massive clusters, as a probe of the physics of star-formation quenching within clusters. Using N-body simulations, we argue that satellit…
SDSS-IV MaNGA: The Spectroscopic Discovery of Strongly Lensed Galaxies
Michael S. Talbot, Joel R. Brownstein, Adam S. Bolton +11
We present a catalogue of 38 spectroscopically detected strong galaxy-galaxy gravitational lens candidates identified in the Sloan Digital Sky Survey IV (SDSS-IV). We were able to…
What to expect from dynamical modelling of galactic haloes II: the spherical Jeans equation
Wenting Wang, Jiaxin Han, Shaun Cole +3
The spherical Jeans equation (SJE) is widely used in dynamical modelling of the Milky Way (MW) halo potential. We use haloes and galaxies from the cosmological Millennium-II simula…
Evidence for radial variations in the stellar mass-to-light ratio of massive galaxies from weak and strong lensing
Alessandro Sonnenfeld, Alexie Leauthaud, Matthew W. Auger +4
The Initial Mass Function (IMF) for massive galaxies can be constrained by combining stellar dynamics with strong gravitational lensing. However, this method is limited by degenera…
