    Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
    The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime...

    Pushing automated morphological classifications to their limits with the Dark Energy Survey
    We present morphological classifications of ~27 million galaxies from the Dark Energy Survey (DES) Data Release 1 (DR1) using a supervised deep learning...

    PyNeb: a new software for the analysis of emission lines
    We describe an ongoing project to migrate the emission-line analysis package nebular from its current environment, IRAF, to a modern programming environment...

    PyNeb: a new tool for analyzing emission lines. I. Code description and validation of results
    Analysis of emission lines in gaseous nebulae yields direct measures of physical conditions and chemical abundances and is the cornerstone of nebular...

    Pyodine: an open, flexible reduction software for iodine-calibrated precise radial velocities
    Context. Many telescopes use an iodine (I 2) absorption cell to measure precise radial velocities (RVs), but their data reduction pipelines are all tailored to...
  • Publication
    Qualitative Interpretation of Galaxy Spectra
    We describe a simple step-by-step guide to qualitative interpretation of galaxy spectra. Rather than an alternative to existing automated tools, it is put...

    Quantifying the coherent outflows of galaxies around voids in the SDSS DR7
    We report the detection, with a high level of confidence, of coherent outflows around voids found in the seventh data release of the Sloan Digital Sky Survey...
  • Publication
    Quantifying the evidence for resonant damping of coronal waves with foot-point wave power asymmetry
    We use Coronal Multi-channel Polarimeter (CoMP) observations of propagating waves in the solar corona together with Bayesian analysis to assess the evidence of...

    QUEST1 Variability Survey. II. Variability Determination Criteria and 200k Light Curve Catalog
    The QUEST (QUasar Equatorial Survey Team) Phase 1 camera has collected multibandpass photometry on a large strip of high Galactic latitude sky over a period of...
