  text: "In the third APOKASC catalog, we present data for the complete sample of
    15,808 evolved stars with APOGEE spectroscopic parameters and Kepler asteroseismology.
    We used 10 independent asteroseismic analysis techniques and anchor our system
    on fundamental radii derived from Gaia L and spectroscopic Teff. We provide evolutionary
    state, asteroseismic surface gravity, mass, radius, age, and the data used to
    derive them for 12,418 stars. This includes 10,036 exceptionally precise measurements,
    with median fractional uncertainties in \r\nvmax, Δν, mass, radius, and age of
    0.6%, 0.6%, 3.8%, 1.8%, and 11.1%, respectively. We provide more limited data
    for 1624 additional stars that either have lower-quality data or are outside of
    our primary calibration domain. Using lower red giant branch (RGB) stars, we find
    a median age for the chemical thick disk of 9.14 ± 0.05(ran) ± 0.9(sys) Gyr with
    an age dispersion of 1.1 Gyr, consistent with our error model. We calibrate our
    red clump (RC) mass loss to derive an age consistent with the lower RGB and provide
    asymptotic GB and RGB ages for luminous stars. We also find a sharp upper-age
    boundary in the chemical thin disk. We find that scaling relations are precise
    and accurate on the lower RGB and RC, but they become more model dependent for
    more luminous giants and break down at the tip of the RGB. We recommend the use
    of multiple methods, calibration to a fundamental scale, and the use of stellar
    models to interpret frequency spacings."

  text: Studies of Galactic structure and evolution have benefited enormously from
    Gaia kinematic information, though additional, intrinsic stellar parameters like
    age are required to best constrain Galactic models. Asteroseismology is the most
    precise method of providing such information for field star populations en masse,
    but existing samples for the most part have been limited to a few narrow fields
    of view by the CoRoT and Kepler missions. In an effort to provide well-characterized
    stellar parameters across a wide range in Galactic position, we present the second
    data release of red giant asteroseismic parameters for the K2 Galactic Archaeology
    Program (GAP). We provide ${\nu }_{\max }$ and ${\rm{\Delta }}\nu $ based on six
    independent pipeline analyses; first-ascent red giant branch (RGB) and red clump
    (RC) evolutionary state classifications from machine learning; and ready-to-use
    radius and mass coefficients, κR and κM, which, when appropriately multiplied
    by a solar-scaled effective temperature factor, yield physical stellar radii and
    masses. In total, we report 4395 radius and mass coefficients, with typical uncertainties
    of 3.3% (stat.) ± 1% (syst.) for κR and 7.7% (stat.) ± 2% (syst.) for κM among
    RGB stars, and 5.0% (stat.) ± 1% (syst.) for κR and 10.5% (stat.) ± 2% (syst.)
    for κM among RC stars. We verify that the sample is nearly complete—except for
    a dearth of stars with ${\nu }_{\max }\lesssim 10\mbox{--}20\,\mu \mathrm{Hz}$—by
    comparing to Galactic models and visual inspection. Our asteroseismic radii agree
    with radii derived from Gaia Data Release 2 parallaxes to within 2.2% ± 0.3% for
    RGB stars and 2.0% ± 0.6% for RC stars.

  text: Brightness variations due to dark spots on the stellar surface encode information
    about stellar surface rotation and magnetic activity. In this work, we analyze
    the Kepler long-cadence data of 26,521 main-sequence stars of spectral types M
    and K in order to measure their surface rotation and photometric activity level.
    Rotation-period estimates are obtained by the combination of a wavelet analysis
    and autocorrelation function of the light curves. Reliable rotation estimates
    are determined by comparing the results from the different rotation diagnostics
    and four data sets. We also measure the photometric activity proxy Sph using the
    amplitude of the flux variations on an appropriate timescale. We report rotation
    periods and photometric activity proxies for about 60% of the sample, including
    4431 targets for which McQuillan et al. did not report a rotation period. For
    the common targets with rotation estimates in this study and in McQuillan et al.,
    our rotation periods agree within 99%. In this work, we also identify potential
    polluters, such as misclassified red giants and classical pulsator candidates.
    Within the parameter range we study, there is a mild tendency for hotter stars
    to have shorter rotation periods. The photometric activity proxy spans a wider
    range of values with increasing effective temperature. The rotation period and
    photometric activity proxy are also related, with Sph being larger for fast rotators.
    Similar to McQuillan et al., we find a bimodal distribution of rotation periods.

  text: We present deep unbiased spectroscopy of the Hubble Ultra Deep Field (UDF)
    carried out using the slitless grism spectroscopy mode of the Advance Camera for
    Surveys on the Hubble Space Telescope (HST). The GRIsm ACS Program for Extragalactic
    Science (GRAPES) achieves continuum detection as faint as zAB=27.2 using 40 orbits
    (9.2×10^4 seconds) on HST. The data were taken at four orientation angles to correct
    for the overlap of spectra. GRAPES data provide a unique, uninterrupted, low resolution
    (R=100) spectral coverage for 5500Å<λ<10500Å, and allow us to detect high redshift
    galaxies at 4<z<7 whether they have $\lya$ lines or just show the Lyman Break,
    as well as find low luminosity AGNs in an unbiased fashion. This paper describes
    in detail the observations and the data reduction, and examines the quality of
    the extracted spectra. Subsequent papers will deal with the analysis of the data.
    The extracted and calibrated GRAPES spectra will be available from MAST at STScI.

  text: The Sloan Digital Sky Survey has confirmed the existence of populations of
    broad absorption line (BAL) quasars with various unusual properties. We present
    and discuss 23 such objects and consider the implications of their wide range
    of properties for models of BAL outflows and quasars in general. We have discovered
    one BAL quasar with a record number of absorption lines. Two other similarly complex
    objects with many narrow troughs show broad Mg II absorption extending longward
    of their systemic host galaxy redshifts. This can be explained as absorption of
    an extended continuum source by the rotation-dominated base of a disk wind. Five
    other objects have absorption that removes an unprecedented ∼90% of all flux shortward
    of Mg II. The absorption in one of them has varied across the ultraviolet with
    an amplitude and rate of change as great as ever seen. This same object may also
    show broad Hβ absorption. Numerous reddened BAL quasars have been found, including
    at least one reddened mini-BAL quasar with very strong Fe II emission. The five
    reddest objects have continuum reddenings of E(B-V) ≃ 0.5, and in two of them
    we find strong evidence that the reddening curve is even steeper than that of
    the SMC. We have found at least one object with absorption from Fe III but not
    Fe II. This may be due to a high column density of moderately high ionization
    gas, but the Fe III level populations must also be affected by some sort of resonance.
    Finally, we have found two luminous, probably reddened high-redshift objects that
    may be BAL quasars whose troughs partially cover different regions of the continuum
    source as a function of velocity.
