  author={I. C. R. Abbasi and E. al.},
  journal={The Astrophysical Journal},
We present new results of searches for neutrino point sources in the northern sky, using data recorded in 2007-2008 with 22 strings of the IceCube detector (approximately one-fourth of the planned total) and 275.7 days of live time. The final sample of 5114 neutrino candidate events agrees well with the expected background of atmospheric muon neutrinos and a small component of atmospheric muons. No evidence of a point source is found, with the most significant excess of events in the sky at 2.2… Expand
Time-integrated Searches for Point-like Sources of Neutrinos with the 40-string IceCube Detector
We present the results of time-integrated searches for astrophysical neutrino sources in both the northern and southern skies. Data were collected using the partially completed IceCube detector inExpand
First search for atmospheric and extraterrestrial neutrino-induced cascades with the IceCube detector

Search for steady and flaring astrophysical neutrino point sources with the IceCube detector
High energy neutrino astronomy relies on the predictions of neutrino fluxes coming from astrophysical objects, for example active galactic nuclei. In these models, neutrinos and gamma-rays areExpand
Searches for high-energy neutrino emission in the Galaxy with the combined IceCube-AMANDA detector

Multimessenger studies of point-sources using the IceCube neutrino telescope and the MAGIC gamma-ray telescope
Three messengers can be used to extract information about the sources of cosmic rays: photons, charged particles (cosmic rays) and neutrinos. In this work the connection between the Very High EnergyExpand
Searches for periodic neutrino emission from binary systems with 22 and 40 strings of IceCube
In this paper, we present the results of searches for periodic neutrino emission from a catalog of binary systems. Such modulation, observed in the photon flux, would be caused by the geometry ofExpand
Search strategies for discovering extraterrestrial neutrinos with IceCube
Abstract With completion expected in 2011, the IceCube Neutrino Observatory is approaching the 1 km 3 scale required for high energy neutrino astronomy. Before completion, the data taken with theExpand
The IceCube Neutrino Observatory: search for extended sources of neutrinos and preliminary study of a communication protocol for its future upgrade
When humans started looking out at a starry night, astronomy was born. Photons emitted by stars travel up to sometimes billions of light years to reach our eyes, and by studying the properties ofExpand
Directional correlations between UHECRs and neutrinos observed with IceCube
Ultra-high energy cosmic rays (UHECR) above an energy threshold of tens of EeV might undergo only small deflections due to interstellar magnetic fields. Their arrival directions would then point toExpand


Detection of atmospheric muon neutrinos with the IceCube 9-string detector
The IceCube neutrino detector is a cubic kilometer TeV to PeV neutrino detector under construction at the geographic South Pole. The dominant population of neutrinos detected in IceCube is due toExpand
Search for Point Sources of High Energy Neutrinos with Final Data from AMANDA-II
We present a search for point sources of high energy neutrinos using 3.8 years of data recorded by AMANDA-II during 2000-2006. After reconstructing muon tracks and applying selection criteriaExpand
Neutrino Astronomy with the MACRO detector
High-energy gamma-ray astronomy is now a well-established —eld, and several sources have been dis- covered in the region from a few gigaelectron volts up to several teraelectron volts. If sourcesExpand
Including systematic uncertainties in confidence interval construction for Poisson statistics
A search for cosmic point sources of neutrinos has been performed using data taken in 1999 with the AMANDA-B10 neutrino telescope. This work describes methods for signal and background separation andExpand
Methods for point source analysis in high energy neutrino telescopes
Abstract Neutrino telescopes are moving steadily toward the goal of detecting astrophysical neutrinos from the most powerful galactic and extragalactic sources. Here we describe analysis methods toExpand
TeV Gamma-ray Sources from a survey of the Galactic Plane with Milagro
A survey of Galactic gamma-ray sources at a median energy of ~20 TeV has been performed using the Milagro Gamma-Ray Observatory. Eight candidate sources of TeV emission are detected with pretrialExpand
Galactic discrete sources of high energy neutrinos
Abstract We review recently developed models of galactic discrete sources of high energy neutrinos. Some of them are based on a simple rescaling of the TeV γ-ray fluxes from recently detectedExpand

Neutrino flux predictions for known Galactic microquasars
It has been proposed recently that Galactic microquasars may be prodigious emitters of TeV neutrinos that can be detected by upcoming km^2 neutrino telescopes. In this paper we consider a sample ofExpand
The H.E.S.S. Survey of the Inner Galaxy in Very High Energy Gamma Rays
The distribution in Galactic latitude of the detected sources appears to be consistent with a scale height in the Galactic disk for the parent population smaller than 100 pc, consistent with expectations for supernova remnants and/or pulsar wind nebulae. Expand
