A Large X-ray Sample of Fossil Groups
Eric D. Miller, Eli Rykoff, Renato de Alencar Dupke +3
We present Chandra snapshot observations of the first large X-ray sample of optically identified fossil groups. For 9 of 14 candidate groups, we are able to determine the X-ray lum…
Asymptotic theory for the semiparametric accelerated failure time model with missing data
Bin Nan, John D. Kalbfleisch, Menggang Yu
We consider a class of doubly weighted rank-based estimating methods for the transformation (or accelerated failure time) model with missing data as arise, for example, in case-coh…
Towards the 2020 vision of the baryon content of galaxy groups and clusters
A. Kravtsov, A. Gonzalez, A. Vikhlinin +12
Groups and clusters of galaxies occupy a special position in the hierarchy of large-scale cosmic structures because they are the largest and the most massive (from ~10^13 Msun to o…
Massive Black Holes Across Cosmic Time
P. Madau, T. Abel, P. Bender +12
This White Paper to the National Academy of Sciences Astro2010 Decadal Review Committee outlines some of the outstanding questions regarding the assembly history of Massive Black H…
How do Galaxies Accrete Gas and Form Stars?
M. E. Putman, P. Henning, A. Bolatto +42
Great strides have been made in the last two decades in determining how galaxies evolve from their initial dark matter seeds to the complex structures we observe at z=0. The role o…
The Role of Dwarf Galaxies in Building Large Stellar Halos
Evan N. Kirby, Puragra Guhathakurta, James S. Bullock +10
The hierarchical theory of galaxy formation rests on the idea that smaller galactic structures merge to form the galaxies that we see today. The past decade has provided remarkable…
