On the Origin of the North Celestial Pole Loop

The Astrophysical Journal, 2023
The North Celestial Pole Loop (NCPL) provides a unique laboratory for studying the early-stage precursors of star formation. Uncovering its origin is key to understanding the dynamical mechanisms that control the evolution of its contents. In this study,

Mapping the Milky Way bulge at high resolution: the 3D dust extinction, CO, and X factor maps

, 2014
Three dimensional interstellar extinction maps provide a powerful tool for stellar population analysis. We use data from the VISTA Variables in the Via Lactea survey together with the Besan\c{c}on stellar population synthesis model of the Galaxy to ...

X-ray Halos and Large Grains in the Diffuse Interstellar Medium [PDF]

, 2001
Recent observations with dust detectors on board the interplanetary spacecraft Ulysses and Galileo have recorded a substantial flux of large interstellar grains with radii between 0.25 and 2.0 mu entering the solar system from the local interstellar ...

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 ...

The mid-infrared extinction law in the darkest cores of the Pipe Nebula

, 2012
Context. The properties of dust grains, in particular their size distribution, are expected to differ from the interstellar medium to the high-density regions within molecular clouds. Aims.

The global dust SED: Tracing the nature and evolution of dust with DustEM [PDF]

, 2010
The Planck and Herschel missions are currently measuring the farIR-mm emission of dust, which combined with existing IR data, will for the first time provide the full SED of the galactic ISM dust emission with an unprecedented sensitivity and angular ...

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

Probing the Distinct Extinction Law of the Pillars of Creation in M16 with JWST

The Astrophysical Journal Letters
Investigating 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).
