CMB anisotropies due to cosmological magnetosonic waves
Tina Kahniashvili, Bharat Ratra
We study scalar mode perturbations (magnetosonic waves) induced by a helical stochastic cosmological magnetic field and derive analytically the corresponding cosmic microwave backg…
Discovery of TeV Gamma-Ray Emission from the Cygnus Region of the Galaxy
A. A. Abdo, B. Allen, D. Berley +36
The diffuse gamma radiation arising from the interaction of cosmic ray particles with matter and radiation in the Galaxy is one of the few probes available to study the origin of t…
A New Force in the Dark Sector?
Glennys R. Farrar, Rachel A. Rosen
We study the kinematics of dark matter using the massive cluster of galaxies 1E0657-56. The velocity of the "bullet" subcluster has been measured by X-ray emission from the shock f…
Gravitational Backreaction of Matter Inhomogeneities
A. Gruzinov, M. Kleban, M. Porrati +1
The non-linearity of Einstein's equations makes it possible for small-scale matter inhomogeneities to affect the Universe at cosmological distances. We study the size of such effec…
The Scale Dependence of Halo and Galaxy Bias: Effects in Real Space
Robert E. Smith, Roman Scoccimarro, Ravi K. Sheth
We examine the scale dependence of dark matter, halo and galaxy clustering on very large scales (0.01<k[h/Mpc]<0.15), due to non-linear effects from dynamics and halo bias. We purs…
Magnetar-Driven Magnetic Tower as a Model for Gamma-Ray Bursts and Asymmetric Supernovae
Dmitri A. Uzdensky, Andrew I. MacFadyen
We consider a newly-born millisecond magnetar, focusing on its interaction with the dense stellar plasma in which it is initially embedded. We argue that the confining pressure and…
