MegaMorph -- multi-wavelength measurement of galaxy structure: Sérsic profile fits to galaxies near and far
Marina Vika, Steven P. Bamford, Boris Haeussler +3
We demonstrate a new multi-wavelength technique for two-dimensional parametric modelling of galaxy surface-brightness profiles, which we have incorporated into the widely used soft…
Evidence for a correlation between the sizes of quiescent galaxies and local environment to z ~ 2
Caterina Lani, Omar Almaini, William G. Hartley +14
We present evidence for a strong relationship between galaxy size and environment for the quiescent population in the redshift range 1 < z < 2. Environments were measured using pro…
Structural Evolution of Early-type Galaxies to z=2.5 in CANDELS
Yu-Yen Chang, Arjen van der Wel, Hans-Walter Rix +18
Projected axis ratio measurements of 880 early-type galaxies at redshifts 1<z<2.5 selected from CANDELS are used to reconstruct and model their intrinsic shapes. The sample is sele…
