LIGO Scientific Collaboration
2007-2011
The LIGO Scientific Collaboration (LSC) glitch group is part of the detector characterization effort. It consists data analysts and experts who, during after science runs, collaborate for a better understanding noise transients in detectors. Goals fifth run (S5) included (1) offline assessment quality, with focus on transients, (2) veto recommendations astrophysical analysis (3) feedback to commissioning team anomalies seen gravitational wave auxiliary channels. Other activities study...
The LIGO detectors are sensitive to a variety of noise transients non-astrophysical origin. Instrumental glitches and environmental disturbances increase the false alarm rate in searches for gravitational waves. Using times already identified when interferometers produced data questionable quality, or channels that monitor interferometer indicated non-stationarity, we have developed techniques safely effectively veto triggers from compact binary coalescences (CBCs) search pipeline.
The LIGO experiment aims to detect and study gravitational waves using ground-based laser interferometry. A critical factor the performance of interferometers, a major consideration in design possible future upgrades, is isolation interferometer optics from seismic noise. We present results detailed programme measurements environment surrounding interferometers. describe experimental configuration used collect data, which were acquired over 613 day period. focused on frequency range 0.1–10...
Using a silicon vertex detector, we measure the charged particle pseudorapidity distribution over range 1.5 to 5.5 using data collected from PbarP collisions at root s = 630 GeV. With sample of 3 million events, deduce result with an overall normalization uncertainty 5%, and typical bin errors few percent. We compare our measurement UA5, generated by Lund Monte Carlo default settings. This is only second this level precision, for greater than 3.
Gravitational-wave observations became commonplace in Advanced LIGO-Virgo's recently concluded third observing run. 56 non-retracted candidates were identified and publicly announced near real time. Gravitational waves from binary neutron star mergers, however, remain of special interest since they can be precursors to high-energy astrophysical phenomena like $γ$-ray bursts kilonovae. While late-time electromagnetic emissions provide important information about the processes within, prompt...
The HERA-B experiment is designed for observation of CP violation in the B-meson system at HERA machine DESY. data acquisition and triggering must cope with a half million detector channels, 40 MHz interaction rate signal to background ratio 10/sup -10/. A highly selective multi-level trigger high bandwidth has been currently being implemented. second-level event buffer mid-level switch will be built from DSP boards carrying SHARC processors. second third level code run on farm 100-200...
