    Infrared Properties of Star-forming Dwarf Galaxies. II. Blue Compact Dwarf Galaxies in the Virgo Cluster
    A sample of 16 blue compact dwarf galaxies (BCDs) in the Virgo Cluster has been imaged in the near-infrared (NIR) in J and Ks on the 2.1 m telescope at the...

    Infrared Space Observatory Investigates the Nature of Extremely Red Hard X-Ray Sources Responsible for the X-Ray Background
    We analyze very deep X-ray and mid-IR surveys in common areas of the Lockman Hole and the Hubble Deep Field-North (HDF-N) to study the sources of the X-ray...

    Inner and outer rings are not strongly coupled with stellar bars
    Rings are distinctive features of many disc galaxies and their location and properties are closely related to the disc dynamics. In particular, rings are often...

    Inner bars also buckle. The MUSE TIMER view of the double-barred galaxy NGC 1291
    Double bars are thought to be important features for secular evolution in the central regions of galaxies. However, observational evidence about their origin...

    Inside-out formation of nuclear discs and the absence of old central spheroids in barred galaxies of the TIMER survey
    The centres of disc galaxies host a variety of structures built via both internal and external processes. In this study, we constrain the formation and...

    Insights into the emission of the blazar 1ES 1011+496 through unprecedented broadband observations during 2011 and 2012
    Context. 1ES 1011+496 (z = 0.212) was discovered in very high-energy (VHE, E> 100 GeV) γ rays with MAGIC in 2007. The absence of simultaneous data at lower...
