A Detection of Circumgalactic Dust at Megaparsec Scales with Maximum Likelihood Estimation

open access: yesThe Astrophysical Journal
One of the more surprising astrophysical discoveries of the past decade has been the presence of enormous quantities of dust at megaparsec distances from galaxies, which has important implications for galaxy evolution, the circumgalactic and ...

Inhomogeneous Dust Biases Photometric Redshifts and Stellar Masses for LSST

open access: yesThe Astrophysical Journal Letters
Spectral energy distribution (SED) modeling is one of the main methods to estimate galaxy properties, such as photometric redshifts, z , and stellar masses, M _* , for extragalactic imaging surveys.

Theoretical Determination of the Binding Energies of Methanol and Related Species onto Amorphous Solid Water Ice

open access: yesThe Astrophysical Journal
The formation and survival of complex organic molecules (COMs) in cold interstellar environments depends on their interactions with icy dust grain surfaces.

Dust coagulation in ISM [PDF]

open access: yes, 1989
Coagulation is an important mechanism in the growth of interstellar and interplanetary dust particles. The microphysics of the coagulation process was theoretically analyzed as a function of the physical properties of the coagulating grains, i.e., their ...

Photocleavage of Aliphatic C–C Bonds in the Interstellar Medium

open access: yesThe Astrophysical Journal
Ultraviolet (UV) processing in the interstellar medium (ISM) induces the dehydrogenation of hydrocarbons. Aliphatics, including alkanes, are present in different interstellar environments, being prevalently formed in evolved stars; thus, the ...

Proposed Importance of HOCO Chemistry: Inefficient Formation of CO2 from CO and OH Reactions on Ice Dust

open access: yesThe Astrophysical Journal
With the advent of JWST ice observations, dedicated studies on the formation reactions of detected molecules are becoming increasingly important. One of the most interesting molecules in interstellar ice is CO _2 .

Interstellar and cometary dust [PDF]

open access: yes, 1989
Aspects of interstellar dust which are known from direct observation will be discussed. Some specific difficulties that various theories have in explaining the observations will be presented.

Sensitivity of Polarization to Grain Shape. II. Aggregates

open access: yesThe Astrophysical Journal
A previous study (Paper I) investigated the polarization properties of a variety of simple convex grain shapes, some of which were found to be consistent with the observed polarization properties of interstellar dust from far-ultraviolet to far-infrared.
