Supernova Blast Waves in Low-Density Hot Media: A Mechanism for Spatially Distributed Heating
structure supernova remnants
2014/12/24
Most supernovae are expected to explode in low-density hot media, particularly in galactic bulges and elliptical galaxies. The remnants of such supernovae, although difficult to detect individually, c...
Detecting relic gravitational waves in the CMB: A statistical bias
Detecting relic gravitational waves statistical bias
2011/10/13
Analyzing the imprint of relic gravitational waves (RGWs) on the cosmic microwave background (CMB) power spectra provides a way to determine the signal of RGWs. In this Letter, we discuss a statistica...
Towards Quark Deconfinement in Neutron Stars via Spindown: Gravitational Waves or Magnetic Braking?
Quark Deconfinement Neutron Stars Gravitational Waves Magnetic Braking
2011/9/28
A phase of interacting quark matter can arise inside the dense core of isolated neutron stars when they have been sufficiently spun down from their initial rapidly rotating configuration. In this work...
Nature's Most Precise Clocks May Make "Galactic GPS" Possible; Pulsing Pulsars Help in Search for Gravitational Waves
Nature's Most Precise Clocks Galactic GPS Pulsing Pulsars Gravitational Waves
2010/1/11
Radio astronomers have uncovered 17 millisecond pulsars in our galaxy by studying unknown high-energy sources detected by NASA's Fermi Gamma-ray Space Telescope. The astronomers made the discovery in ...
CMB Temperature Polarization Correlation and Primordial Gravitational Waves：WMAP5
cosmic microwave background Primordial Gravitational Waves
2009/9/4
we continue our study of the CMB temperature polarization (TE) cross-correlation as a source of information about primordial gravitational waves (PGWs). In a previous paper, we considered two methods ...
