The Effect of Gas Fraction on the Morphology and Time-scales of Disc Galaxy Mergers
Jennifer M. Lotz, Patrik Jonsson, T. J. Cox +1
Gas-rich galaxy mergers are more easily identified by their disturbed morphologies than mergers with less gas. Because the typical gas fraction of galaxy mergers is expected to inc…
The Effect of Mass Ratio on the Morphology and Time-scales of Disc Galaxy Mergers
Jennifer M. Lotz, Patrik Jonsson, T. J. Cox +1
The majority of galaxy mergers are expected to be minor mergers. The observational signatures of minor mergers are not well understood, thus there exist few constraints on the mino…
Gravity-driven Lyman-alpha blobs from cold streams into galaxies
Tobias Goerdt, A. Dekel, A. Sternberg +3
We use high-resolution cosmological hydrodynamical AMR simulations to predict the characteristics of La emission from the cold gas streams that fed galaxies in massive haloes at hi…
Cosmology: small scale issues revisited
Joel R. Primack
The abundance of dark matter satellites and subhalos, the existence of density cusps at the centers of dark matter halos, and problems producing realistic disk galaxies in simulati…
Dark Matter and Galaxy Formation
Joel R. Primack
The four lectures that I gave in the XIII Ciclo de Cursos Especiais at the National Observatory of Brazil in Rio in October 2008 were (1) a brief history of dark matter and structu…
Modeling gamma-ray burst observations by Fermi and MAGIC including attenuation due to diffuse background light
Rudy C. Gilmore, Francisco Prada, Joel R. Primack
Gamma rays from extragalactic sources are attenuated by pair-production interactions with diffuse photons of the extragalactic background light (EBL). Gamma-ray bursts (GRBs) are a…
GeV Gamma-Ray Attenuation and the High-Redshift UV Background
Rudy C. Gilmore, Piero Madau, Joel R. Primack +2
We present new calculations of the evolving UV background out to the epoch of cosmological reionization and make predictions for the amount of GeV gamma-ray attenuation by electron…
The Growth of Supermassive Black Holes Across Cosmic Time
K. Nandra, J. A. Aird, D. M. Alexander +54
One of the main themes in extragalactic astronomy for the next decade will be the evolution of galaxies over cosmic time. Many future observatories, including JWST, ALMA, GMT, TMT…
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…
Strong gravitational lensing probes of the particle nature of dark matter
Leonidas A. Moustakas, Kevork Abazajian, Andrew Benson +44
There is a vast menagerie of plausible candidates for the constituents of dark matter, both within and beyond extensions of the Standard Model of particle physics. Each of these ca…
Structure and Substructure of Galactic Spheroids
Aaron J. Romanowsky, Jean P. Brodie, James S. Bullock +6
The full spatio-chemo-dynamical structure of galaxies of all types and environments at low redshift provides a critical accompaniment to observations of galaxy formation at high re…
Cosmology: small scale issues
Joel R. Primack
The abundance of dark matter satellites and subhalos, the existence of density cusps at the centers of dark matter halos, and problems producing realistic disk galaxies in simulati…
A New Era in Extragalactic Background Light Measurements: The Cosmic History of Accretion, Nucleosynthesis and Reionization
Asantha Cooray, Alexandre Amblard, Charles Beichman +52
(Brief Summary) What is the total radiative content of the Universe since the epoch of recombination? The extragalactic background light (EBL) spectrum captures the redshifted ener…
