SHORT DURATION GAMMA-RAY BURSTS (GRBS) ARE BRIEF AND INTENSE FLASHES OF GAMMA-RAY RADIATION LOCATED AT COSMOLOGICAL DISTANCES. NASA S SWIFT MISSION PROVIDED THE FIRST BREAKTHROUGH OBSERVATIONS CONNECTING THESE HIGH-ENERGY TRANSIENTS TO THE COALESCENCE OF TWO COMPACT OBJECTS EITHER TWO NEUTRON STARS (NSS) OR A NS AND A BLACK HOLE (BH). SHORT GRBS ARE THEREFORE PRIME CANDIDATE ELECTROMAGNETIC COUNTERPARTS OF GRAVITATIONAL WAVE SOURCES DETECTABLE BY ADVANCED LIGO. UNFORTUNATELY ONLY A FRACTION OF SHORT GRBS VISIBLE BY SWIFT IS PROMPTLY IDENTIFIED BY THE ON-BOARD TRIGGER SYSTEM. A LARGER NUMBER OF EVENTS FAILS TO PASS THE ON-BOARD TRIGGER SELECTION AND GOES UNNOTICED. LUCKILY THIS SUBSET OF EVENTS IS NOT LOST. IT IS INSTEAD DOWNLINKED THROUGH A LOW-PRIORITY CHANNEL AND THEN ARCHIVED. THE GOAL OF THIS ADAP PROPOSAL IS TO HARVEST THIS RICH POPULATION OF GAMMA-RAY TRANSIENTS BURIED IN THE DATA ARCHIVE. WE PROPOSE TO 1) SYSTEMATICALLY MINE THIS UNTAPPED RESOURCE OF THE SWIFT ARCHIVE IN ORDER TO DISCOVER NEW SHORT GRBS; 2) CORRELATE THE SWIFT UNTRIGGERED DATASET WITH SIGNALS DETECTED BY OTHER FACILITIES (E.G FERMI INTEGRAL) AT OTHER WAVELENGTHS (E.G. FAST RADIO BURSTS) OR WITH OTHER MESSENGERS (E.G. GRAVITATIONAL WAVES); 3) DEVELOP AND RELEASE THE RELEVANT TOOLS AND DOCUMENTATION TO THE COMMUNITY IN ORDER TO FACILITATE THE EXPLOITATION OF THIS VALUABLE DATASET IN FUTURE YEARS. THE PROPOSED RESEARCH WILL SIGNIFICANTLY EXPAND THE CURRENT DATABASE OF SHORT GRBS AND AID MULTI-MESSENGER SEARCHES OF TRANSIENT PHENOMENA. BY STUDYING THE BEHAVIOR OF MATTER IN EXTREME PHYSICAL CONDITIONS THE FORMATION OF NEW BLACK HOLES AND GRAVITY THIS PROJECT DIRECTLY ADDRESSES NASA STRATEGIC OBJECTIVE 1.6 A KEY SCIENCE GOAL IN THE AREA OF COSMIC ORIGINS.
