    Galaxy Ages with Redshift z = 2–4: Stellar Population Synthesis for Candidates in FourStar Galaxy Evolution Survey
    Observations of large amounts of massive galaxies with relatively old populations found at high redshifts are challenging galaxy formation scenarios within the...

    Gamma-ray Excess from a Stacked Sample of High- and Intermediate-frequency Peaked Blazars Observed with the MAGIC Telescope
    Between 2004 and 2009, a sample of 28 X-ray selected high- and intermediate-frequency peaked blazars with an X-ray flux larger than 2 μJy at 1 keV in the...

    Gas and Dust Emission from the Nuclear Region of the Circinus Galaxy
    Simultaneous modeling of the line and continuum emission from the nuclear region of the Circinus galaxy is presented. Composite models that include the combined...

    Gasdynamics in NGC 5248: Fueling a Circumnuclear Starburst Ring of Super-Star Clusters
    Through observations and modeling, we demonstrate how the recently discovered large-scale bar in NGC 5248 generates spiral structure that extends from 10 kpc...

    GD-1 Stellar Stream and Cocoon in the DESI Early Data Release
    We present ∼115 new spectroscopically identified members of the GD-1 tidal stream observed with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We...

    Generalized T<SUB>e</SUB>([O III])–T<SUB>e</SUB>(He I) Discrepancies in Ionized Nebulae: Possible Evidence of Case B Deviations and Temperature Inhomogeneities
    The physics of recombination lines in the He I singlet system is expected to be relatively simple, supported by accurate atomic models. We examine the...

    Geometry Diagnostics of a Stellar Flare from Fluorescent X-Rays
    We present evidence of Fe fluorescent emission in the Chandra HETGS spectrum of the single G-type giant HR 9024 during a large flare. In analogy to solar X-ray...
