The First Data Release of the Sloan Digital Sky Survey
/ SDSS Collaboration
The Sloan Digital Sky Survey has validated and made publicly available its First Data Release. This consists of 2099 square degrees of five-band (u, g, r, i, z) imaging data, 186,240 spectra of galaxies, quasars, stars and calibrating blank sky patches selected over 1360 square degrees of this area, and tables of measured parameters from these data.

Sloan Digital Sky Survey IV: Mapping the Milky Way, Nearby Galaxies and the Distant Universe
/ Blanton, Michael R. (Stanford U., Phys. Dept.) ; Bershady, Matthew A. (Wisconsin U., Madison, Astron.) ; Abolfathi, Bela ; Albareti, Franco D. (Madrid, Autonoma U. ; Madrid, IFT) ; Allende Prieto, Carlos ; Almeida, Andres ; Alonso-García, Javier ; Anders, Friedrich (Potsdam, Astrophys. Inst.) ; Anderson, Scott F. (LLNL, Livermore) ; Andrews, Brett et al.
We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and high signal-to-noise ratio in the near-infrared.

(Swarthmore Coll.) ; Ahmed, Zeeshan (SLAC) et al.
The axion is a hypothetical, well-motivated dark-matter particle whose existence would explain the lack of charge-parity violation in the strong interaction. [...]

(Montana State U.) ; Berthereau, A. (LPC2E, Orleans ; Station Radioastronomy, Nancay) ; Bonetti, M. (Milan Bicocca U. ; INFN, Milan Bicocca) et al.
We searched for an isotropic stochastic gravitational wave background in the second data release of the International Pulsar Timing Array, a global collaboration synthesizing decadal-length pulsar-timing campaigns in North America, Europe, and Australia. In our reference search for a power law strain spectrum of the form $h_c = A(f/1\,\mathrm{yr}^{-1})^{\alpha}$, we found strong evidence for a spectrally-similar low-frequency stochastic process of amplitude $A = 3.8^{+6.3}_{-2.5}\times10^{-15}$ and spectral index $\alpha = -0.5 \pm 0.5$, where the uncertainties represent 95% credible regions, using information from the auto- and cross-correlation terms between the pulsars in the array.
