    The VLT-FLAMES Tarantula Survey. XVI. The optical and NIR extinction laws in 30 Doradus and the photometric determination of the effective temperatures of OB stars
    Context. The commonly used extinction laws of Cardelli et al. (1989, ApJ, 345, 245) have limitations that, among other issues, hamper the determination of the...

    Thermal emission from the amorphous dust: An alternative possibility of the origin of the anomalous microwave emission
    Complete studies of the radiative processes of thermal emission from the amorphous dust from microwave through far-infrared wavebands are presented by taking...

    Time-resolved infrared emission from radiation-driven central obscuring structures in active galactic nuclei
    The central engines of Seyfert galaxies are thought to be enshrouded by geometrically thick gas and dust structures. In this paper, we derive observable...

    Unveiling the inner Milky Way globular cluster system
    A serious limitation in the study of the Galactic inner halo and bulge globular clusters has been the existence of large and differential extinction by...

    Unveiling the Structure of the Planetary Nebula M2-48
    The PN M2-48 is formed by three main structures, namely, a bipolar central region (CR), a set of knots tracing a semicircular shell surrounding CR, and two...

    Very Small Array observations of the anomalous microwave emission in the Perseus region
    The dust complex G159.6-18.5 in the Perseus region has previously been observed with the COSMOSOMAS experiment on angular scales of ~1°, and was found to...

    Very small grain emission in NGC 7023.
    We observed the reflection nebula NGC 7023 at various positions using wide and narrow band photometry centred on the 7.7 and 11.3μm PAH emission features and...

    VVV WIN 1733-3349: a low extinction window to probe the far side of the Milky Way bulge
    Windows of low extinction in the Milky Way (MW) have been used along the past decades for the study of the Galactic structure and the stellar population across...

    Wavelength-dependent kinematics in the dusty inclined galaxy NGC 2146
    We present measurements of the apparent rotation curves of the dusty inclined spiral NGC 2146 taken using conventional long-slit spectroscopy in the red and...
