Stars and dark matter in the spiral gravitational lens 2237+0305

C. M. Trott, T. Treu, L. V. E. Koopmans +1

We construct a mass model for the spiral lens galaxy 2237+0305, at redshift z_l=0.04, based on gravitational-lensing constraints, HI rotation, and new stellar-kinematic information…

Cosmological constraints from 21cm surveys after reionization

Eli Visbal, Abraham Loeb, Stuart Wyithe

21cm emission from residual neutral hydrogen after the epoch of reionization can be used to trace the cosmological power spectrum of density fluctuations. Using a Fisher matrix for…

Gravitational Radiation from Accreting Millisecond Pulsars

Matthias Vigelius, Donald Payne, Andrew Melatos

It is widely assumed that the observed reduction of the magnetic field of millisecond pulsars can be connected to the accretion phase during which the pulsar is spun up by mass acc…

Gamma-ray Constraints on Dark Matter Annihilation into Charged Particles

Nicole F. Bell, Thomas D. Jacques

Dark matter annihilation into charged particles is necessarily accompanied by gamma rays, produced via radiative corrections. Internal bremsstrahlung from the final state particles…

Evidence for Merger-Driven Activity in the Clustering of High Redshift Quasars

Stuart Wyithe, Abraham Loeb

Recently, a very large clustering length has been measured for quasars at a redshift of z~4. In combination with the observed quasar luminosity function we assess the implications…
