We construct a SCUBA-2 450 μm map in the COSMOS field that covers an area of 300 arcmin2 and reaches a 1σ noise level of 0.65 mJy in the deepest region. We extract 256 sources detected at 450 μm with signal-to-noise ratios >4.0 and analyze the physical properties of their multiwavelength counterparts. We find that most of the sources are at z lesssim 3, with a median of $z={1.79}_{-0.15}^{+0.03} \% $. About ${35}_{-25}^{+32} \% $ of our sources are classified as starburst galaxies based on… Expand
ALMACAL VII: first interferometric number counts at 650 μm

Rotational Disruption of Astrophysical Dust and Ice—Theory and Applications
Dust is an essential component of the interstellar medium (ISM) and plays an important role in many different astrophysical processes and phenomena. Traditionally, dust grains are known to beExpand
Effects of rotational disruption on the evolution of grain size distribution in galaxies
Interstellar dust grains can be spun up by radiative torques, and the resulting centrifugal force may be strong enough to disrupt large dust grains. We examine the effect of this rotationalExpand

Variation of Dust Properties with Cosmic Time Implied by Radiative Torque Disruption
Dust properties within a galaxy are known to change from the diffuse medium to dense clouds due to increased local gas density. However, the question of whether dust properties change with redshiftExpand
