Polycyclic aromatic hydrocarbons, ionized gas, and molecular hydrogen in brightest cluster galaxies of cool-core clusters of galaxies
Megan Donahue,Geneviève E. de Messières,Robert W. O'Connell,G. Mark Voit,Aaron Hoffer,Brian R. McNamara,Brian R. McNamara,Brian R. McNamara,Paul Nulsen +8 more
TL;DR: In this paper, the authors present measurements of 5-25 μm emission features of brightest cluster galaxies (BCGs) with strong optical emission lines in a sample of nine cool-core clusters of galaxies observed with the Infrared Spectrograph on board the Spitzer Space Telescope.

Regional sources of pollution aerosol at Barrow, Alaska during winter 1979–1980 as deduced from elemental tracers
TL;DR: A seven-element tracer system for regional pollution aerosol has been applied to 100 daily samples of aerosol from Barrow, Alaska during winter 1979-1980, using regional signatures from eastern N America, Europe, and the Soviet Union as mentioned in this paper.

Reconstructing seawater δ18O from paired coral δ18O and Sr/Ca ratios: Methods, error analysis and problems, with examples from Tahiti (French Polynesia) and Timor (Indonesia)

TL;DR: In this paper, the authors compare several statistical routines that may be used to calculate delta O-18 and SSS from paired coral Sr/Ca and delta O -18 measurements, showing that covariance leads to a bias in the coefficients of the univariate regression equations.

Global characteristics of the cold plasma in the equatorial plasmapause region as deduced from the Geos 1 Mutual Impedance Probe
TL;DR: In this paper, the authors used the mutual impedance experiment on GEOS 1 (4 < L < 8, 0000-2400 MLT) to measure the electron density and temperature of the outer plasmasphere (when kTe/Ne < 1.6 eV/cm³).

TL;DR: In this paper, the authors present the current results from their ongoing radial velocity survey of the intermediate-age (2.4 Gyr) open cluster NGC 6819, using both newly observed and other available photometry and astrometry, and define a primary target sample of 1454 stars that includes main-sequence, subgiant, giant, and blue straggler stars, spanning a magnitude range of 11?V? 16.5 and an approximate mass range of 1.6 M?.
