  • Target-of-opportunity Observations of Gravitational-wave Events with Vera C. Rubin Observatory
  • 2022

    • The discovery of the electromagnetic counterpart to the binary neutron star (NS) merger GW170817 has opened the era of gravitational-wave multimessenger astronomy. Rapid identification of the optical/infrared kilonova enabled a precise localization of the source, which paved the way to deep multiwavelength follow-up and its myriad of related science results. Fully exploiting this new territory of exploration requires the acquisition of electromagnetic data from samples of NS mergers and other gravitational-wave sources. After GW170817, the frontier is now to map the diversity of kilonova properties and provide more stringent constraints on the Hubble constant, and enable new tests of fundamental physics. The Vera C. Rubin Observatory's Legacy Survey of Space and Time can play a key role in this field in the 2020s, when an improved network of gravitational-wave detectors is expected to reach a sensitivity that will enable the discovery of a high rate of merger events involving NSs (∼tens per year) out to distances of several hundred megaparsecs. We design comprehensive target-of-opportunity observing strategies for follow-up of gravitational-wave triggers that will make the Rubin Observatory the premier instrument for discovery and early characterization of NS and other compact-object mergers, and yet unknown classes of gravitational-wave events.

  • The secondary prevention of low back pain : a controlled study with follow-up
  • 1989
  • In: Pain. - : Elsevier. - 0304-3959 .- 1872-6623. ; 36:2, s. 197-207
  • Journal article (peer-reviewed)abstract
    • The current investigation studied the effectiveness of a secondary prevention program for nurses with back pain who were deemed at risk for developing a chronic problem. A 2 × 3 repeated measures design was employed with 2 groups and 3 assessment periods. The treatment group received an intervention designed to reduce current problems, but above all to prevent reinjury and minor pains from becoming chronic medical problems, and it included a physical and behavioral therapy package. The control group was placed on a waiting-list. Results indicated that the treatment group had significantly greater improvements than the control group for pain intensity, anxiety, sleep quality and fatigue ratings, observed pain behavior, activities, mood, and helplessness. These differences were generally maintained at the 6 month follow-up. In addition, the treatment group broke a trend for increasing amounts of pain-related absenteeism, while the control group did not. Taken as a whole, the results suggest that a secondary prevention program aimed at altering life style factors may represent an effective method for dealing with musculoskeletal pain problems.
