    Resolved observations at 31 GHz of spinning dust emissivity variations in ρ Oph
    The ρ Oph molecular cloud is one of the best examples of spinning dust emission, first detected by the cosmic background imager (CBI). Here, we present 4.5...

    SDC13 infrared dark clouds: Longitudinally collapsing filaments?
    Formation of stars is now believed to be tightly linked to the dynamical evolution of interstellar filaments in which they form. In this paper we analyze the...

    Small-scale clustering of nano-dust grains in supersonic turbulence
    We investigate the clustering and dynamics of nano-sized particles (nano dust) in high-resolution (1024 3) simulations of compressible isothermal hydrodynamic...

    Spectroscopy of the Earth Observed as a Distant Planet
    Through ground-based observations of the Earth's spectrum from California, satellite observations of clouds, and an atmospheric radiative transfer code, we have...

    Stellar Feedback and the Evolution of Young Embedded Star Clusters
    In this contribution we present the first results of an theoretical attempt to address the question of the evacuation time-scale but also the star-formation...

    Study of the GeV to TeV morphology of the γ Cygni SNR (G 78.2+2.1) with MAGIC and Fermi-LAT. Evidence for cosmic ray escape
    Context. Diffusive shock acceleration (DSA) is the most promising mechanism that accelerates Galactic cosmic rays (CRs) in the shocks of supernova remnants...

    Substellar objects in star formation regions: A deep near infrared study in the Serpens cloud
    We present near infrared (J, H and Ks) observations of a 5'× 10' sample field in the Serpens Star Formation region obtained with SOFI at the NTT. These...

    Super Star Clusters Versus OB Associations
    Super star clusters (M ecl > 105 M sun) are the largest stellar nurseries in our local Universe, containing hundreds of thousands to millions of young stars...

    Temperature fluctuations in H II regions: Ionization by cosmic rays as a key mechanism
    We present a detailed model capable of explaining quantitatively the temperature fluctuations observed in luminous, large H II regions. The model is based on...
