Awards: G1245046120, G1700342535, Development of Novel Statistical Tools for the Analysis of Astronomical Data, Discovering the Most Enigmatic Transient Phenomena in the Time-Domain, NEO DISCOVERY AND CHARACTERIZATION WITH THE PAN-STARRS PS1 TELESCOPE. WE WILL USE THE PAN-STARRS PS1 TELESCOPE SYSTEM TO RAPIDLY SURVEY LARGE AREAS O, G253522920, Collaborative Research: A Multi-Wavelength Observational and Theoretical Study of the Fastest Evolving Stellar Explosions, G3154294395, Cosmology in the Local Volume with Hawai'i Supernova Flows, TO TAKE FULL ADVANTAGE OF THE K2 SUPERNOVA COSMOLOGY EXPERIMENT WE PLAN TO FOLLOW ALL SUPERNOVA CANDIDATES FROM FOUR TELESCOPES THE 1.8-M PAN-STARRS TELESCOPE ON HALEAKALA 1.5-M RATIR TELESCOPE AT SAN PEDRO MATIR THE 1-M NICKEL TELESCOPE AT LICK OBSERVATORY AND THE 1-M SWOPE TELESCOPE AT LAS CAMAPANAS OBSERVATORY. IN COMBINATION WE WILL FOLLOW EVERY K2 SUPERNOVA IN 13 BANDS (UBVGRRIIZYYJH). THE DIFFERENT SITES ALLOW FOR BOTH IMPROVED CADENCE (BEING AT DIFFERENT LONGITUDES) AND MITIGATES AGAINST POOR WEATHER AT A SINGLE SITE. MOREOVER THE PAN-STARRS AND SWOPE TELESCOPES ARE PARTICULARLY WELL-CALIBRATED. THE PAN-STARRS TELESCOPE WAS USED TO DISCOVER AND MONITOR ~5000 HIGH-Z SUPERNOVAE AND IS CURRENTLY USED FOR THE LOW-Z FOUNDATION SURVEY. THE SWOPE TELESCOPE WAS USED FOR THE CARNEGIE SUPERNOVA PROJECT WHICH HAS ALSO OBSERVED HUNDREDS OF SUPERNOVAE. OBSERVATIONS ON THESE WELL-CALIBRATED SYSTEMS WILL DIRECTLY LINK THE K2 SUPERNOVAE TO A THOUSANDS OF OTHER SUPERNOVAE OBSERVED ON THESE SYSTEMS. OUR PROGRAM HAS THREE MAIN GOALS. FIRST WE WILL PROVIDE THE BEST DISTANCES TO TYPE IA SUPERNOVAE. THIS WILL ALLOW US TO IMPROVE KEPLER MEASUREMENTS OF IMPORTANT PHYSICAL PARAMETERS SUCH AS RADII OF THE PROGENITOR STARS. IT WILL ALSO ALLOW US TO LOOK FOR SUBTLE CORRELATIONS BETWEEN THE K2 LIGHT CURVES AND HUBBLE RESIDUALS. SECOND WE WILL USE THE K2 TYPE IA SUPERNOVAE AS A "ROSETTA" SAMPLE ANCHORED TO THE PAN-STARRS SYSTEM. AS THE K2 SUPERNOVAE WILL UNDOUBTEDLY BE OBSERVED BY MANY TELESCOPES IT IS A RARE OPPORTUNITY TO CROSS-CALIBRATE ALL TELESCOPES USING SUPERNOVAE THEMSELVES. THE PAN-STARRS TELESCOPE HAS ALREADY OBSERVED THE ENTIRE CAMPAIGN 16 FOOTPRINT AND HAS BEEN UBERCALIBRATED ACROSS THE ENTIRE SKY MAKING IT THE IDEAL SYSTEM TO BE THE ANCHOR. FINALLY WE WILL MONITOR ALL NEWLY DISCOVERED SUPERNOVAE AT HIGH CADENCE IN MULTIPLE BANDS. BECAUSE OF OUR DIFFERENT SITES WE WILL BE ABLE TO MONITOR THE SUPERNOVAE FOR A PARTICULARLY LONG CONTINUOUS PERIOD. OUR FILTERED OBSERVATIONS AT THESE EARLY TIMES WILL PROVIDE IMPORTANT COLOR INFORMATION TO COMPLEMENT THE KEPLER LIGHT CURVES. IN ADDITION TO OUR PHOTOMETRIC RESOURCES WE WILL SPECTROSCOPICALLY OBSERVE THESE SUPERNOVAE WITH TELESCOPES FROM LICK KECK LAS CAMPANAS APACHE POINT CERRO TOLOLO AND KITT PEAK OBSERVATORIES., The Progenitors and Explosions of Type Ia Supernovae and Exotic Transients, CDS&E: Collaborative Research: Development and Application of Machine Learning Classification of Optical Transients, G4026262344, G4084488544, G4161815245, Mapping the cosmic expansion history with Type Ia supernovae, G433322167, G434337789, G4498084077, Frameworks: SCiMMA: Real-time Orchestration of Multi-Messenger Astrophysical Observations, THE POWER OF THE PAN-STARRS1 TELESCOPE TO DISCOVER NEOS HAS BEEN AMPLY DEMONSTRATED WITH THE CURRENT 11% DEDICATED ALLOCATION OF OBSERVING TIME SUPPO, G5077163979, EPSCoR Research Fellows: NSF: Building a Duke University and University of Hawaii Collaboration for the Next Decade of Supernova Cosmology, G5304172058, Next-Generation Supernova Cosmology, G5771713820, G58316358, G6273510985, G6538072225, G6671297155, A NEO SEARCH PROGRAM USING THE PAN-STARRS PS1 TELESCOPETHE GOAL OF THE PROPOSED RESEARCH IS TO USE T, G6770599008, Collaborative Research: Exploring the Formation and Growth of Supermassive Black Holes through Variability and Transients, CAREER: Understanding the Nature of Dark Energy with the Young Supernova Experiment and the Legacy Survey of Space and Time, Pan-STARRS1: Operations; Public Data Release; Education and Outreach, G814503682, THE OBJECTIVE OF THIS PROPOSAL IS TO SIGNIFICANTLY UPGRADE THE PAN-STARRS TELESCOPE SYSTEM ON HALEAKALA, MAUI BY COMPLETING THE INSTRUMENTATION AND C, CAREER: A Holistic Study of Compact-Object Mergers across the Electromagnetic Spectrum, WE PROPOSE TO CONTINUE OUR SURVEY TO DISCOVER NEAR EARTH OBJECTS (NEOS) WITH THE PAN-STARRS SYSTEM EXPANDED TO INCLUDE THE PAN-STARRS2 OBSERVATORY (PS2) TOGETHER WITH THE PAN-STARRS1 OBSERVATORY (PS1). SINCE THE START OF DEDICATED USE OF PAN- STARRS FOR NEO DISCOVERY IN SPRING OF 2014 PS1 HAS DISCOVERED OVER 40% OF ALL NEOS AND OVER 50% OF THE LARGER NEOS AND POTENTIALLY HAZARDOUS ASTEROIDS. PS1 IS ALSO THE LEADING DISCOVERY TELESCOPE FOR NEOS LARGER THAN 1 KM IN DIAMETER. WITH PS2 WE WILL AT LEAST DOUBLE OUR RAW SURVEY POWER. THE PAN-STARRS2 OBSERVATORY IS COMPLETE AND WE EXPECT TO COMPLETE ITS CAMERA (GPC2) SOON AND ADD SCIENCE OPERATIONS WITH PS2 TO THE ONGOING PS1 SURVEY. PS2 WILL BE IN FULL SCIENCE OPERATIONS BY THE START OF THE PERIOD OF PERFORMANCE OF THIS PROPOSAL. THE PS2 OPTICS ARE SUPERIOR TO THOSE OF PS1 AND WE HAVE ELIMINATED THE CAUSE OF CORRELATED READ NOISE THAT AFFLICTS FAINT OBJECTS IN THE CAMERA ON PS1. THUS WE EXPECT PS2 TO BE SLIGHTLY SUPERIOR TO PS1 IN DISCOVERING NEOS. THE PAN-STARRS SYSTEM WITH BOTH PS1 AND PS2 WILL CHANGE THE LANDSCAPE OF NEO DISCOVERY. WE CAN DOUBLE THE AREA SURVEYED OR PERFORM SELF FOLLOW-UP OBSERVATIONS WHICH WILL SIGNIFICANTLY DECREASE THE NUMBER OF OBJECTS LOST DUE TO AN ABSENCE OF FOLLOW-UP. MORE SELF-FOLLOW-UP WILL ALSO AVOID BIASES INTRODUCED BY THE DIGEST SCORE AND PROVIDE A MORE SYSTEMATIC SURVEY. WE WILL INVESTIGATE WIDE AREA SURVEY STRATEGIES RANGING BETWEEN THESE TWO EXTREMES TO OPTIMIZE FOR THE MOST COMPLETE NEO SURVEY AND TO REDUCE LOSSES OF RARE OR CAMOUFLAGED NEOS THAT WE ARE CURRENTLY UNDER-SAMPLING. IN ADDITION TO BRINGING THE SURVEY POWER OF PS2 ON LINE WE HAVE IDENTIFIED PROMISING AVENUES WHERE WE CAN IMPROVE OUR DISCOVERY RATE BY ADVANCES IN SOFTWARE INCLUDING IMPROVED DE-TRENDING ASTROMETRY OBJECT DETECTION IMAGE SUBTRACTION AND MACHINE LEARNING TECHNIQUES. FINALLY WE HAVE AN EXPERIENCED TEAM WITH A PROVEN RECORD OF SUCCESS.
