Detecting the Cosmic Web: Lyα Emission from Simulated Filaments at z=3
Lydia M. Elias, Shy Genel, Amiel Sternberg +4
The standard cosmological model (CDM) predicts the existence of the cosmic web: a distribution of matter into sheets and filaments connecting massive halos. However, observation…
Cosmological insights into the assembly of the radial and compact stellar halo of the Milky Way
Lydia M. Elias, Laura V. Sales, Amina Helmi +1
Recent studies using Gaia DR2 have identified a massive merger in the history of the Milky Way (MW) whose debris is markedly radial and counterrotating. This event, known as the Ga…
The Halos and Environments of Nearby Galaxies (HERON) I: Imaging, Sample Characteristics, and Envelope Diameters
R. Michael Rich, Aleksandr Mosenkov, Henry Lee-Saunders +16
We use a dedicated 0.7-m telescope to image the halos of 119 galaxies in the Local Volume to mag/arcsec. The sample is primarily from the 2MASS Large Galaxy At…
Stellar Halos in Illustris- Probing the Histories of Milky Way-Mass Galaxies
Lydia M. Elias, Laura V. Sales, Peter Creasey +4
The existence of stellar halos around galaxies is a natural prediction of the hierarchical nature of the LambdaCDM model. Recent observations of Milky Way-like galaxies have reveal…
