The Empath’s Travel Log

Cynthia Marie Hoffman Studner said of the poem, This is an ambitious poem that delivers on empathy, just as promised. The poem establishes a metaphor of a “taught thread” that pulls together the traveler and an “orange-coated mutt” spotted in Italy, and this thread weaves throughout the poem as one of continual and deep connection with others. One wonders of the empath’s fate, especially when the poem begins with the story of wives cremated beside their dead husbands. What are the implications of this empathy in terms of its being something the speaker must bear? At times, it is guilt, as in the case of the baby rabbit that cannot be saved. Later, it is the insensitivity of a father who laughs and orders a rabbit cooked and delivered on a plate. It seems the speaker ultimately comes to find purpose and usefulness in empathy, saving animals after all (making the dream come true in which “the thread connecting/ me to you does not snap,/ and you live,/ and you live”). But it is the stark absence of animals and others in the final section that haunts me. The tension and strangeness in the ending lines is satisfying in a way that resists closure. I want more, but at the same time, I don’t want more. And that seems just right

Gamma-Ray Pulsar Studies with GLAST

Some pulsars have their maximum observable energy output in the gamma-ray band, offering the possibility of using these high-energy photons as probes of the particle acceleration and interaction processes in pulsar magnetospheres. After an extended hiatus between satellite missions, the recently-launched AGILE mission and the upcoming Gamma-ray Large Area Space Telescope (GLAST) Large Area Telescope (LAT) will allow gamma-ray tests of the theoretical models developed based on past discoveries. With its greatly improved sensitivity, better angular resolution, and larger energy reach than older instruments, GLAST LAT should detect dozens to hundreds of new gamma-ray pulsars and measure luminosities, light curves, and phase-resolved spectra with unprecedented resolution. It will also have the potential to find radio-quiet pulsars like Geminga, using blind search techniques. Cooperation with radio and X-ray pulsar astronomers is an important aspect of the LAT team's planning for pulsar studies.Comment: 8 pages, 5 figures.

Space Detectors for Gamma Rays (100 MeV - 100 GeV): from EGRET to Fermi LAT

The design of spaceborne high-energy (E>100 MeV) gamma-ray detectors depends on two principal factors: (1) the basic physics of detecting and measuring the properties of the gamma rays; and (2) the constraints of operating such a detector in space for an extended period. Improvements in technology have enabled major advances in detector performance, as illustrated by two successful instruments, EGRET on the Compton Gamma Ray Observatory and LAT on the Fermi Gamma-ray Space Telescope.Comment: 11 pages, 7 figures, submitted to Comptes Rendus Physiqu
