An Origami Approximation to the Cosmic Web

Mark C. Neyrinck

The powerful Lagrangian view of structure formation was essentially introduced to cosmology by Zel'dovich. In the current cosmological paradigm, a dark-matter-sheet 3D manifold, in…

Constraints on Radial Migration in Spiral Galaxies I. Analytic Criterion for Capture at Corotation

Kathryne J. Daniel, Rosemary F. G. Wyse

Near the corotation resonance of a transient spiral arm, stellar orbital angular momenta may be changed without inducing significant kinematic heating, resulting in what has come t…

ZFOURGE/CANDELS: On the Evolution of M* Galaxy Progenitors from z=3 to 0.5

Casey Papovich, I. Labbé, R. Quadri +38

Galaxies with stellar masses near M* contain the majority of stellar mass in the universe, and are therefore of special interest in the study of galaxy evolution. The Milky Way (MW…
