The Fundamental Manifold of Spheroids
Dennis Zaritsky, Anthony H. Gonzalez, Ann I. Zabludoff
We present a unifying empirical description of the structural and kinematic properties of all spheroids embedded in dark matter halos. We find that the stellar spheroidal component…
Probing Galaxy Formation with He II Cooling Lines
Yujin Yang, Ann I. Zabludoff, Romeel Davé +5
Using high resolution cosmological simulations, we study hydrogen and helium gravitational cooling radiation. We focus on the HeII cooling lines, which arise from gas with a differ…
Disentangling Morphology, Star Formation, Stellar Mass, and Environment in Galaxy Evolution
Daniel Christlein, Ann Zabludoff
We present a study of the spectroscopic and photometric properties of galaxies in six nearby clusters. We perform a partial correlation analysis on our dataset to investigate wheth…
Can Early Type Galaxies Evolve from Fading the Disks of Late Types?
Daniel Christlein, Ann Zabludoff
We examine whether early-type galaxies in clusters may have evolved from later types by the fading of their disks (e.g., as a result of ram-pressure stripping or strangulation) or…
