Constraints on heavy unstable neutrinos from galaxy formation
Joel R. Primack,Marco Roncadelli +1 more
TL;DR: In this paper, a new bound on the lifetime of nonradiatively decaying heavy neutrinos VH was derived from the requirement that the universe be dominated by nonrelativistic matter after the epoch of recombination, in order that galaxies and clusters have time to grow from small fluctuations in the early universe.

Particle Astrophysics after COBE: Blois92 Summary Talk
TL;DR: The most interesting things discussed at Blois were the near-success of CDM in predicting the COBE fluctuation amplitude, which favors the hypothesis that structure formed in the universe through gravitational collapse as mentioned in this paper.

Origin and Destiny of Dark Matter Halos: Cosmological Matter Exchange and Metal Enrichment
Tsafrir S. Kolatt,James S. Bullock,Avishai Dekel,Joel R. Primack,Yair Sigad,Andrey V. Kravtsov,Anatoly Klypin +6 more
TL;DR: In this paper, the exchange of dark matter between halos, subhalos, and their environments in a high-resolution cosmological N-body simulation of a Lambda CDM cosmology is analyzed.
Book ChapterDOI
Supersymmetry and Cosmology
TL;DR: In this article, the authors reviewed the observational constraints on the mass of the gravitino and possibly also the photino and showed that if the mass lies near the cosmological upper bound, ~ 1 keV, then gravitinos play an important role in galaxy formation.

TL;DR: In this article, the authors present a suite of high-resolution cosmological zoom-in simulations to z = 4 of a 1012Me halo at z = 0, obtained using seven contemporary astrophysical simulation codes (ART-I, ENZO, RAMSES, CHANGA, GADGET-3, GEAR, and GIZMO) widely used in the numerical galaxy formation community.
