Inspiral Analysis Group Results and Plans Patrick Brady, UWM for the Inspiral Group G060560-00-Z

S3/S4 Joint Analysis S3/S4 analysis is complete: 6 searches Primordial black holes, binary neutron stars, binary black holes over two data sets. No plausible detections. Paper draft circulated earlier in the week. Thomas Cokelaer corresponding author. Will keep paper moving through LSC publication process Want final version in mid December; approval? Backed up by several technical papers: galaxy pop., systematics, pipeline, tuning. 08/15/2006

List of projects - Urgent S5 BNS/BBH; paper by Feb '07; see later S3 Spinning BBH (new analysis); paper in prep S4 Ringdown (new analysis); paper in Mar '07 Follow-ups/detection checklist Most urgent project being addressed by group, Automation of follow-ups, Improving vetoes, signal-based vetoes, ..... 08/15/2006

List of projects – cont'd S5 GRB triggered search; paper in Jun '07 S4/S5 Spinning BBH; improved search methods; preliminary results in March. S5 higher mass (>~ 30Msun); preliminary results in March. Signal based vetoes Hierarchical pipeline 08/15/2006

Publication plan for S5 data Masses m1,m2>1.0Msun, m1+m2<~30.0Msun One calendar year analysis Return epoch #1 to blind. Tune and analyze. Improvements: Better cover mass range, i.e. eliminate squares; chisq for higher masses; coherent H1/H2 statistic; Improve mapping between SNR and false alarm; Improve coincidence methods Complete result including draft paper Feb '07. 08/15/2006

Final Issue: Preparing for detection Group continues to gear its detection checklist http://www.lsc-group.phys.uwm.edu/iulgroup/papers/policy/detection.pdf Prepare proposal for full scale mock detection challenge; ideas right now. Discussion of blind analysis procedures to avoid bias at detection stage; recent dry run reminded people that this goes both ways. 08/15/2006
