On the complementarity of pulsar timing and space laser interferometry for supermassive black hole binaries individual detection
complementarity pulsar timing space laser interferometry supermassive black hole
2011/10/14
For the observation of an individual supermassive black hole binary (SMBHB), the complementarity between pulsar timing (PT) and space laser interferometry (SLI) has been previously suggested. Herein s...
Dense Molecular Gas Excitation at High Redshift: Detection of HCO+(J=4-3) Emission in the Cloverleaf Quasar
galaxies active — galaxies starburst — galaxies formation — galaxies
2010/11/10
We report the detection of HCO+(J=4→3) emission in the Cloverleaf Quasar at z=2.56, using
the IRAM Plateau de Bure Interferometer. HCO+ emission is a star formation indicator similar
to HCN, tracing...
The Detection of a Population of Submillimeter-Bright, Strongly-Lensed Galaxies
Population Submillimeter-Bright Strongly-Lensed Galaxies
2010/11/11
Gravitational lensing is a powerful astrophysical and cosmological probe and is particularly valuable at submillimeter wavelengths for the study of the statistical and individual properties of dusty s...
The effect of M dwarf starspot activity on low-mass planet detection thresholds
planetary systems stars activity stars atmospheres stars spots techniques
2010/11/11
In light of the growing interest in searching for low mass, rocky planets, we investigate the
impact of starspots on radial velocity searches for earth-mass planets in orbit about M dwarf
stars. Sin...
The MIDAS Experiment: A New Technique for the Detection of Extensive Air Showers
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/4
Recent measurements suggest free electrons created in ultra-high energy cosmic ray extensive air showers (EAS) can interact with neutral air molecules producing Bremsstrahlung radiation in the microwa...
Detection of an X-ray Pulsation for the Gamma-ray Pulsar Centered in CTA 1
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/27
We report the detection of X-ray pulsations with a period of ~315.87 ms from the 2009 XMM-Newton observation for the radio-quiet gamma-ray pulsar, LAT PSR J0007+7303, centered in the supernova remnant...
Dark Matter detection via lepton cosmic rays
High Energy Astrophysical Phenomena (astro-ph.HE) Cosmology and Extragalactic Astrophysics (astro-ph.CO) High Energy Physics - Phenomenology (hep-ph)
2010/12/23
Recent observations of lepton cosmic rays, coming from the PAMELA and FERMI experiments, have pushed our understanding of the interstellar medium and cosmic rays sources to unprecedented levels.
