Lack of Interaction between the Dust Grains and the Anomalous Radio Jet in the Nearby Spiral Galaxy NGC 4258 [PDF]

, 2010
We obtained Spitzer/IRAC 3.6-8 micron images of the nearby spiral galaxy NGC 4258 to study possible interactions between dust and the radio jet. In our analysis we also included high-resolution radio continuum, H-alpha, CO, and X-ray data.

The origin of dust in galaxies revisited: the mechanism determining dust content

, 2012
The origin of cosmic dust is a fundamental issue in planetary science. This paper revisits the origin of dust in galaxies, in particular, in the Milky Way, by using a chemical evolution model of a galaxy composed of stars, interstellar medium, metals ...

Collisional evolution of dust aggregates. From compaction to catastrophic destruction [PDF]

Astronomy & Astrophysics, 2009
The coagulation of dust aggregates occurs in various astrophysical environments. Each one is characterized by different conditions that influence the growth, e.g. relative velocities, composition, and size of the smallest constituents (monomers). Here we study the microphysics of collisions of dust aggregates in a four-dimensional parameter space.

Interstellar Carbonaceous Dust Erosion Induced by X-Ray Irradiation of Water Ice in Star-forming Regions

The Astrophysical Journal, 2023
The chemical inventory of protoplanetary midplanes is the basis for forming planetesimals. Among them, solid-state reactions based on CO/CO _2 toward molecular complexity on interstellar dust grains have been studied in theoretical and laboratory work ...

Modelling Dust Evolution in Galaxies with a Multiphase, Inhomogeneous ISM [PDF]

, 2016
We develop a model of dust evolution in a multiphase, inhomogeneous ISM including dust growth and destruction processes. The physical conditions for grain evolution are taken from hydrodynamical simulations of giant molecular clouds in a Milky Way-like ...

Dust destruction by the supernova remnant forward shock in a turbulent interstellar medium

Astronomy & Astrophysics
Context. While supernova remnants (SNRs) have been observed to produce up to 1 M⊙ of dust, the amount of dust destroyed by the forward shock is poorly constrained, raising the question of whether they are net dust producers or destroyers. Aims.

Genesis and evolution of dust in galaxies in the early Universe I. Modeling dust evolution in starburst galaxies

, 2011
We have developed a numerical galactic chemical evolution model. The model is constructed such that the effect of a wide range of parameters can be investigated.
