Probing Galaxy Formation with TeV Gamma Ray Absorption
Joel R. Primack, James S. Bullock, Rachel S. Somerville +1
We present here the extragalactic background light (EBL) predicted by semi-analytic models of galaxy formation, and show how measurements of the absorption of gamma rays of …
Constraining the IMF using TeV gamma ray absorption
J. S. Bullock, R. S. Somerville, D. MacMinn +1
Gamma rays of ~TeV energies from distant sources suffer attenuation due to pair production off of ~1 micron EBL photons. We may exploit this process in order to indirectly measure…
Formation of Dark Matter Halos
J. R. Primack, J. S. Bullock, A. A. Klypin +1
This article concerns the formation and structure of dark matter halos, including (1) their radial density profiles, (2) their abundance, and (3) their merger rates. The last topic…
Comments on non-Gaussian density perturbations and the production of primordial black holes
James S. Bullock, Joel R. Primack
We review the basic arguments for the likelihood of non-Gaussian density perturbations in inflation models with primordial black hole (PBH) production. We discuss our derived distr…
