Limitations of the modified blackbody fit method for determining molecular cloud properties
Astronomische Nachrichten, Volume 345, Issue 4, May 2024.Abstract Achieving a comprehensive understanding of the star and planet formation process is one of the fundamental tasks of astrophysics, requiring detailed knowledge of the physical conditions during the different phases of this process. During the earliest stages, that is, concerning physical processes in molecular clouds and filaments, the column ...

Chiroptical properties of membrane glycerophospholipids and their chiral backbones
Chirality, Volume 36, Issue 3, March 2024.Examination of the interaction of glycerophospholipids with circularly polarized light suggests that direct induction of symmetry breaking to membrane lipids by chiral photons is unlikely. However, anisotropy spectra of certain analogs indicate potential alternative mechanisms for the origins of membrane lipid homochirality, providing insights into the

Active Metasurfaces for Non‐Rigid Light Sail Interstellar Optical Communication
Advanced Theory and Simulations, Volume 7, Issue 1, January 2024.Non‐rigidity of the nanophotonic light sail deformation that leads to varying angles of incidence and polarization across the aperture, significantly impacting unit cells' performance. It proposes a reflective all‐dielectric, low‐power active metasurface that dynamically counteracts the deformations in the shape of the light sail caused by the non ...

Probing the Distinct Extinction Law of the Pillars of Creation in M16 with JWST
The Astrophysical Journal LettersInvestigating the extinction law in regions of high dust extinction, such as the Pillars of Creation within the M16 region, is crucial for understanding the densest parts of the interstellar medium (ISM).

The Global Structure of Molecular Clouds. I. Trends with Mass and Star Formation Rate
The Astrophysical Journal, 2023 We introduce a model for the large-scale, global 3D structure of molecular clouds. Motivated by the morphological appearance of clouds in surface density maps, we model clouds as cylinders, with the aim of backing out information about the volume density

Parameterizing the interstellar dust temperature [PDF]
, 2017 The temperature of interstellar dust particles is of great importance to astronomers. It plays a crucial role in the thermodynamics of interstellar clouds, because of the gas-dust collisional coupling.

SOFIA Observations of 30 Doradus. II. Magnetic Fields and Large-scale Gas Kinematics
The Astrophysical Journal, 2023 The heart of the Large Magellanic Cloud, 30 Doradus, is a complex region with a clear core-halo structure. Feedback from the stellar cluster R136 has been shown to be the main source of energy creating multiple parsec-scale expanding-shells in the outer ...
