    A large sub-Neptune transiting the thick-disk M4 V TOI-2406
    Context. Large sub-Neptunes are uncommon around the coolest stars in the Galaxy and are rarer still around those that are metal-poor. However, owing to the...

    A large, long-lived structure near the trojan L5 point in the post common-envelope binary SDSS J1021+1744
    SDSS J1021+1744 is a detached, eclipsing white dwarf/M dwarf binary discovered in the Sloan Digital Sky Survey (SDSS). Outside the primary eclipse, the light...

    A late jet rebrightening revealed from multiwavelength monitoring of the black hole candidate XTE J1752-223
    We present optical monitoring of the black hole candidate XTE J1752-223 during its 2009-10 outburst and decay to quiescence. The optical light curve can be...

    A linear-filter approach to extracting the Rees-Sciama effect in merging clusters of galaxies
    We discuss the prospects for detecting the Rees-Sciama (RS) effect associated with merging clusters of galaxies in millimetric observations. Using the extended...

    A Link Between White Dwarf Pulsars and Polars: Multiwavelength Observations of the 9.36-minute Period Variable Gaia22ayj
    White dwarfs (WDs) are the most abundant compact objects, and recent surveys have suggested that over a third of WDs in accreting binaries host a strong (B ≳ 1...

    A logNHI = 22.6 Damped Lyα Absorber in a Dark Gamma-Ray Burst: The Environment of GRB 050401
    The optical afterglow spectrum of GRB 050401 (at z=2.8992+/-0.0004) shows the presence of a damped Lyα absorber (DLA), with logNHI=22.6+/-0.3. This is the...

    A long-term modulation in XTEJ1716-389: an SS433-like system
    We report on the properties of a 99.3-d periodic modulation in the X-ray transient XTEJ1716-389. We associate this source with the transient KSJ1716-389, first...
