J14.00001: Overview of Advanced LIGO searches for unmodeled transients Jonah Kanner Sources of gravitational wave transients may include some of the most energetic events in the universe, including mergers of neutron stars and/or black holes, the core-collapse of massive stars, and cosmic string cusps. A network of modern gravitational wave detectors, including Advanced LIGO and Advanced Virgo, might soon be capable of observing these sources. Separating these signals from detector noise requires specialized algorithms, which are run both in low-latency and on archived data. In this talk, we describe the all-time, all-sky search for unmodeled transients during the first observing run of Advanced LIGO. [Preview Abstract] |

J14.00002: Status of searches for compact binaries in aLIGO with PyCBC Christopher Biwer Advanced LIGO began its first observing in September 2015. Gravitational waves from binary neutron stars, binary black holes and neutron star-black hole binaries are an important science goal for Advanced LIGO. The PyCBC search uses match filtering to correlate LIGO data with a bank of templates to search for transient gravitational-wave from compact object binaries with a total mass between 2 and 100 solar masses with spin. In this talk, we describe results of the PyCBC search during the first aLIGO observing run. [Preview Abstract] |

J14.00004: Characterization of the Advanced LIGO detectors during their first observing run Jess McIver The Advanced LIGO gravitational wave detectors have recently completed their first observing run from September 2015 - January 2016. Characterization of non-astrophysical transient artifacts in the detectors is crucial to the mitigation of noise sources that contaminate the astrophysical gravitational wave transient searches as well as the interpretation of any candidate event identified by these algorithms. This talk addresses transient noise sources during the first Advanced LIGO observing run and summarizes techniques to monitor and mitigate their impact on the astrophysical searches.

J14.00005: Characterization of GW transients in Advanced LIGO Ben Farr Advanced LIGO recently completed its first observing run, which collected gravitational wave data with unprecedented sensitivity between September 2015 and January 2016. One of Advanced LIGO's primary goals is to detect and characterize gravitational waves from transient sources such as the coalescence of binary compact objects containing neutron stars and/or stellar mass black holes. We will report on the characterization efforts applied to past and future Advanced LIGO candidates. [Preview Abstract] |

J14.00006: Astrophysical Implications Drawn from Advanced LIGO's First Observing Run Daniel Holz, Gijs Nelemans Following a major instrumentation upgrade, the Advanced LIGO detectors recently completed the first observing run. In this talk I will highlight constraints expected to be drawn from the analysis of this observational data set, in the context of astrophysical models for the formation and eventual mergers of binary compact objects in a wide range of stellar environments.

J14.00007: The Quest for the astrophysical background with Advanced LIGO/Virgo Tania Regimbau In addition to the cosmological background, an astrophysical background may have resulted from the superposition of a large number of unresolved sources since the beginning of stellar activity. This astrophysical contribution could be a foreground masking the cosmological background but it can also provide very interesting informations, not only about the physical properties of the respective astrophysical populations, complementing individual GW detections, but also about the evolution of these objects with redshift, the star formation history or the metallicity. In this talk, predictions of the gravitational wave background formed by all the compact binary coalescences at cosmological distances will be given, as well as a discussion of their accessibility with the network of Advanced LIGO/Virgo detectors. Finally, the expected astrophysical and cosmological constraints to be made by Advanced LIGO/Virgo will be presented. [Preview Abstract] |

J14.00008: Tests of General Relativity with gravitational waves from compact binary coalescences with Advanced LIGO Walter Del Pozzo Gravitational waves from compact binary systems provide access to the hitherto unexplored non-linear regime of Einstein’s theory of general relativity. The Advanced LIGO first observing run successfully achieved a sensitivity a few times better than the initial generation of interferometers in the hundred hertz frequency band. In this talk, I will describe the methods devised to verify the predictions of general relativity in the Advanced Detector era. [Preview Abstract] |
