    A magnified compact galaxy at redshift 9.51 with strong nebular emission lines
    Ultraviolet light from early galaxies is thought to have ionized gas in the intergalactic medium. However, there are few observational constraints on this epoch...

    A Major Star Formation Region in the Receding Tip of the Stellar Galactic Bar
    We present an analysis of the optical spectroscopy of 58 stars in the Galactic plane at l=27^° , where a prominent excess in the flux distribution and star...

    A Major Star Formation Region in the Receding Tip of the Stellar Galactic Bar. II. Supplementary Information and Evidence that the Bar is not the Same Structure as the Triaxial Bulge Previously Reported
    This paper is the second part in a series, the first part of which presented an outline of the analysis of 60 spectra from a follow-up program to the Two Micron...

    A Mass Model for the Lensing Cluster SDSS J1004+4112: Constraints from the Third Time Delay
    We have built a new model for the lens system SDSS J1004+4112 including the recently measured time delay of the fourth quasar image. This time delay has a...

    A mass of less than 15 solar masses for the black hole in an ultraluminous X-ray source
    Most ultraluminous X-ray sources have a typical set of properties not seen in Galactic stellar-mass black holes. They have luminosities of more than 3 × 1039...

    A Massive Cluster of Red Supergiants at the Base of the Scutum-Crux Arm
    We report on the unprecedented red supergiant (RSG) population of a massive young cluster, located at the base of the Scutum-Crux Galactic arm. We identify...

    A Massive Hot Jupiter Orbiting a Metal-rich Early M Star Discovered in the TESS Full-frame Images
    Observations and statistical studies have shown that giant planets are rare around M dwarfs compared with Sun-like stars. The formation mechanism of these...

    A massive open cluster hiding in full sight
    Obscuration and confusion conspire to limit our knowledge of the inner Milky Way. Even at moderate distances, the identification of stellar systems becomes...

    A Maximum Likelihood Method for Bidimensional Experimental Distributions and Its Application to the Galaxy Merger Fraction
    The determination of the galaxy merger fraction of field galaxies using automatic morphological indices and photometric redshifts is affected by several biases...
