Searches for gravitational waves from known pulsars with S5 LIGO data

The LIGO Scientific Collaboration, The Virgo Collaboration, B. P. Abbott +678

We present a search for gravitational waves from 116 known millisecond and young pulsars using data from the fifth science run of the LIGO detectors. For this search ephemerides ov…

Search for gravitational-wave bursts associated with gamma-ray bursts using data from LIGO Science Run 5 and Virgo Science Run 1

LIGO Scientific Collaboration, Virgo Collaboration, B. P. Abbott +665

We present the results of a search for gravitational-wave bursts associated with 137 gamma-ray bursts (GRBs) that were detected by satellite-based gamma-ray experiments during the…

Searching for Dark Matter in Messier 33

Enrico Borriello, Giuseppe Longo, Gennaro Miele +4

Among various approaches for indirect detection of dark matter, synchrotron emission due to secondary electrons/positrons produced in galactic WIMPs annihilation is raising an incr…

Search for Gamma Ray Bursts with the Argo-YBJ Detector in Scaler Mode

YBJ Collaboration, G. Aielli

We report on the search for Gamma Ray Bursts (GRBs) in the energy range 1-100 GeV in coincidence with the prompt emission detected by satellites using the Astrophysical Radiation w…

Upper limit on the cosmic-ray photon fraction at EeV energies from the Pierre Auger Observatory

The Pierre Auger Collaboration, J. Abraham, P. Abreu +458

From direct observations of the longitudinal development of ultra-high energy air showers performed with the Pierre Auger Observatory, upper limits of 3.8%, 2.4%, 3.5% and 11.7% (a…

The growth and evolution of super massive black holes

S. Murray, R. Gilli, P. Tozzi +19

We discuss the central role played by X-ray studies to reconstruct the past history of formation and evolution of supermassive Black Holes (BHs), and the role they played in shapin…

Limit on the diffuse flux of ultra-high energy tau neutrinos with the surface detector of the Pierre Auger Observatory

The Pierre Auger Collaboration

Data collected at the Pierre Auger Observatory are used to establish an upper limit on the diffuse flux of tau neutrinos in the cosmic radiation. Earth-skimming may interact…

ARGO-YBJ constraints on very high energy emission from GRBs

YBJ Collaboration, G. Aielli

The ARGO-YBJ (Astrophysical Radiation Ground-based Observatory at YangBaJing) experiment is designed for very high energy -astronomy and cosmic ray researches. Due to the full c…

Evolution of the cosmic ray anisotropy above 10^{14} eV

M. Aglietta, V. V. Alekseenko, B. Alessandro +23

The amplitude and phase of the cosmic ray anisotropy are well established experimentally between 10^{11} eV and 10^{14} eV. The study of their evolution into the energy region 10^{…
