    The Nearest Ultra Diffuse Galaxy: UGC 2162
    We describe the structural, stellar population and gas properties of the nearest ultra diffuse galaxy discovered so far: UGC 2162 (z = 0.00392 {R}e,g=1.7(+/- 0...

    The Negative Baryon Acoustic Oscillation Shift in the Lyα Forest from Cosmological Simulations
    We present the first measurement of the Lyα forest baryon acoustic oscillations (BAO) shift parameter from cosmological simulations. In particular, we generate...

    The Number of Dwarf Satellites of Disk Galaxies versus their Bulge Mass in the Standard Model of Cosmology
    There is a correlation between the bulge mass of the three main galaxies of the Local Group (LG), i.e., M31, Milky Way (MW), and M33, and the number of their...

    The Number of Tidal Dwarf Satellite Galaxies in Dependence of Bulge Index
    We show that a significant correlation (up to 5σ) emerges between the bulge index, defined to be larger for a larger bulge/disk ratio, in spiral galaxies with...

    The Observational and Numerical Analysis of the Rayleigh–Taylor Instability beneath a Hedgerow Prominence
    Using Swedish 1 m Solar Telescope Crisp Imaging Spectro-Polarimeter 6563 Å (Hα) observations and MANCHA3D simulations, we analyze the formation and evolution of...

    The Observed Evolution of the Stellar Mass-Halo Mass Relation for Brightest Central Galaxies
    We quantify evolution in the cluster-scale stellar mass-halo mass (SMHM) relation's parameters using 2323 clusters and brightest central galaxies (BCGs) over...

    The Observed Mass Distribution of Galactic Black Hole LMXBs Is Biased against Massive Black Holes
    The discovery of gravitational-wave radiation from merging black holes (BHs) also uncovered BHs with masses in the range of ≍20-160 M ⊙. In contrast, the most...

    The Odd Offset between the Galactic Disk and Its Bar in NGC~3906
    We use mid-infrared 3.6 and 4.5 μm imaging of NGC 3906 from the Spitzer Survey of Stellar Structure in Galaxies (S4G) to understand the nature of an unusual...

    The OmegaWhite Survey for Short-period Variable Stars. V. Discovery of an Ultracompact Hot Subdwarf Binary with a Compact Companion in a 44-minute Orbit
    We report the discovery of the ultracompact hot subdwarf (sdOB) binary OW J074106.0–294811.0 with an orbital period of {P}{orb}=44.66279+/- 1.16× {10}-4 minutes...
