Associations between Scattering Screens and Interstellar Medium Filaments [PDF]

open access: yesThe Astrophysical Journal
Pulsar scintillation can be used to measure small-scale structure in the Galaxy, but little is known about the specific interstellar medium (ISM) features that cause scintillation.

Deep Learning for Position Angle Quantification Applied to Interstellar Filaments

open access: yesThe Astronomical Journal
Studying filamentary structures opened a door for understanding the conditions of star formation and interstellar medium properties. Present-day algorithms for identifying filaments and their orientations require careful individual parameterization for ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight. [PDF]

open access: yesExp Physiol
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Turbulence in the interstellar medium [PDF]

open access: yes, 2014
Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and ...

Technology requirements of exploration beyond Neptune by solar sail propulsion [PDF]

open access: yes, 2010
This paper provides a set of requirements for the technology development of a solar sail propelled Interstellar Heliopause Probe mission. The mission is placed in the context of other outer solar systems missions, ranging from a Kuiper Belt mission ...

Formation and evolution of interstellar filaments; Hints from velocity dispersion measurements [PDF]

open access: yes, 2013
International audienceWe investigate the gas velocity dispersions of a sample of filaments recently detected as part of the Herschel Gould Belt Survey in the IC 5146, Aquila, and Polaris interstellar clouds.

Planck intermediate results XXXIII. Signature of the magnetic field geometry of interstellar filaments in dust polarization maps [PDF]

open access: yes, 2015
Planck observations at 353 GHz provide the first fully sampled maps of the polarized dust emission towards interstellar filaments and their backgrounds (i.e., the emission observed in the surroundings of the filaments). The data allow us to determine the

Aspect ratios of far-infrared and H i filaments in the diffuse interstellar medium at high Galactic latitudes [PDF]

open access: yes, 2023
Dusty magnetized structures observable in the far-infrared (FIR) at high Galactic latitudes are ubiquitous and found to be closely related to HI filaments with coherent velocity structures. Considering dimensionless morphological characteristics based on

Characterization of cells of amniotic fluids by immunological identification of intermediate-sized filaments: Presence of cells of different tissue origin [PDF]

open access: yes, 1981
Antibodies against intermediate-sized filaments, of the prekeratin or vimentin type, were used to investigate the presence of these filaments by indirect immunofluorescence microscopy in cultured and non-cultured amniotic fluid cells, in frozen sections ...

Profiles of interstellar cloud filaments

open access: yes, 2012
Context. Sub-millimetre observations suggest that the filaments of interstellar clouds have rather uniform widths and can be described with the so-called Plummer profiles.
