I2.00001: Advanced LIGO quest for Gravitational Waves Astronomy. Invited Speaker: Michele Zanolin In this talk I will summarize the current efforts and prospects of the Laser Interferometer Gravitational Wave Observatory (LIGO) to detect Gravitational Wave transients of astronomical origin. Particular focus will be given on the current status of the instruments (Advanced LIGO started the collection of data in September 2015) and the perspectives for the incoming years.

I2.00002: Steering Astronomy Toward Gravitational Wave-Supernova Science Kiranjyot Gill \par Core-Collapse supernovas (CCSNe) mark the dynamic and explosive end of the lives of massive stars by emitting the gravitational wave that is detectable by detectors such as the Laser Interferometer Gravitational-Wave Observatory (LIGO). LIGO has been one of the first collaborations to create ways to collect and analyze data that would distinguish the gravitational waves from background noise produced on Earth. Optical observations of supernovas in the Local Universe provide trigger times (with a typical uncertainty of a few days) and precise sky locations, while an electromagnetic observation would provide a core-collapse trigger time (with an uncertainty of a few seconds) and a sky location. We describe a method that takes into account optical and electromagnetic observational techniques for detection of CCSNe within the Local Universe, which encompasses a volume of 20 Mpc. Providing distance sensitivity estimates for the rate of CCSNe within the Local Field and the Virgo Cluster specializes the implementation of the CCSNe rate toward specifically gravitational wave detection.

I2.00003: Overview of the Coherent WaveBurst Pipeline for the Laser Interferometer Gravitational-Wave Observatory Sophia Schwalbe With the herald of the second generation of the Laser Interferometer Gravitational-Wave Observatory (LIGO), this presentation aims to provide a brief overview of the coherent waveburst (cwb) pipeline for LIGO. This pipeline evaluates if the data collected contains a short burst gravitational wave (GW) and how it can be tuned to search for these waves from di?erent sources, such as binary star systems or, speci?cally for this presentation, supernovae. The pipeline itself ?rst processes the data, then converts the processed data into the time-frequency domain and determines potential candidates for GWs. The candidates are determined by the excess power correlated (coherent) between detectors around the world. The e?ciency of the pipeline for the particular emission model is tested through the injection of signals that model the GW of the source. [Preview Abstract] |

I2.00004: Gravitational Waves Science with Core-Collapse Supernova Marek Szczepanczyk The advance-generation Gravitational Wave Observatories will provide remarkable sensitivity to detect Gravitational Waves from Core-Collapse Supernova. I will discuss the LIGO/Virgo efforts to infer the Gravitational Wave signature from exploding stars. I will summarize the endeavor to extract waveform details, estimate physical parameters and learn about Core-Collapse Supernova dynamics from Gravitational Waves observed from the next nearby Core-Collapse event.
