    Panchromatic Observations and Modeling of the HV Tau C Edge-on Disk
    We present new high spatial resolution (lsim0farcs1) 1-5 μm adaptive optics images, interferometric 1.3 mm continuum and 12CO 2-1 maps, and 350 μm, 2.8 and 3.3...

    Parsec-scale Dust Emission from the Polar Region in the Type 2 Nucleus of NGC 424
    Advancements in infrared (IR) interferometry open up the possibility to spatially resolve active galactic nuclei (AGNs) on the parsec-scale level and study the...

    Pattern Speeds of Bars and Spiral Arms from Hα Velocity Fields
    We have applied the Tremaine-Weinberg method to 10 late-type barred spiral galaxies using data cubes, in Hα emission, from the FaNTOmM and GHAFAS Fabry-Perot...

    Peculiar Transverse Velocities of Galaxies from Quasar Microlensing. Tentative Estimate of the Peculiar Velocity Dispersion at z ~ 0.5
    We propose to use the flux variability of lensed quasar images induced by gravitational microlensing to measure the transverse peculiar velocity of lens...

    Peering into the Dark Side: Magnesium Lines Establish a Massive Neutron Star in PSR J2215+5135
    New millisecond pulsars (MSPs) in compact binaries provide a good opportunity to search for the most massive neutron stars. Their main-sequence companion stars...

    PG 1553+113: Five Years of Observations with MAGIC
    We present the results of five years (2005-2009) of MAGIC observations of the BL Lac object PG 1553+113 at very high energies (VHEs; E > 100 GeV). Power-law...
