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

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
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 ...

Sensitivity of Polarization to Grain Shape. II. Aggregates
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.
