  1. S5 First EpochBNS Inspiral Results Drew Keppel1 representing the Inspiral Group 1California Institute of Technology Nov LSC Meeting MIT, 4 November 2006 LIGO-G060556-00-Z

  2. Summary • Start of run (11/4/05) to start of LHO commissioning (02/06/06) • Standard 1 - 3 M 2pN inspiral templates • Search pipeline (filter, vetoes, coincidence) • Full Data Results • No detection • Upper Limit • 0.17 L10-1 yr-1 for 1.35 M • Mass dependent • Future plans

  3. S5 First Epoch BNS Analysis Distance to optimally oriented 1.4,1.4 M BNS at  = 8 First S5 Epoch Nov 4, 2005 - Feb 6, 2006 current target sensitivity shown in sensemon 2k 4k

  4. Parameter Accuracyof recovered software injections • Mchirp accuracy: 0.01 M sun • End time accuracy: 5 ms

  5. Accidental Coincidencesand Simulated Signals • Tune pipeline using background, playground (10% of data) and injections • Measure background by applying time slides before coincidence • Add simulated signals to detector data to evaluate analysis performance

  6. Vetoes • Two types of Vetoes are used to eliminate false triggers • Data Quality Vetoes • Signal-Based Vetoes • 2 waveform consistency test • 2 time above threshold veto • Data Quality Vetoes: categorized • Cat. 1 • Data not analyzed • H1:H2_OUT_OF_LOCK • Cat. 2 & 3 • Triggers discarded • MASTER_OVERFLOW_LSC • PRE_LOCKLOSS_120_SEC • All vetoed injections above coincide with glitches.

  7. H1H2 Amplitude Consistency • Effective Distance Cut • For triggers with both H1 and H2 triggers • Consistency Cut • For triggers with one Hanford trigger when both were in science mode

  8. H1H2 Effective Distance Cut

  9. Efficiency Curve • 50% efficiency at 25 Mpc

  10. Population Model • The galaxy catalog has been extended to 100 Mpc • only complete to 25 Mpc • we are now sensitive to those distances • The upper limit has used a catalog extended to 75 Mpc

  11. S5 Epoch 1 Full Data • All triggers consistent with background Signal with SNR 8 in H1 and L1 detectors would appear here

  12. Upper Limit • Gaussian Mass Distribution • centered around 1.35 M • Luminosity for H1H2L1 times: 177 L10 • Upper Limit: 0.17 L10-1 yr-1 • Uniform Mass Distribution • Luminosity for H1H2L1 times: • 2-3 M: 155 L10 • 3-4 M: 294 L10 • 4-5 M: 499 L10 • 5-6 M: 1077 L10 • 1 MWEG = 1.7 L10,B • Switched to L10’s because of error in MWEG

  13. Mass DependentUpper Limit S2 Rate L10-1 yr-1 S3/S4 0.19 0.11 0.06 0.03 Total Mass M

  14. Future for S5 BNS • Follow up of loudest events in First Epoch • Adding Coherent Code to Pipeline • Post-Newtonian search from 2 to ~30 Total M from 1 calendar year of S5 data • Goal is a result presented at March LSC Meeting 2007

  15. The End
