Dust-gas scaling relations and oh abundance in the galactic ISM
(IOP Publishing, 2018)
Observations of interstellar dust are often used as a proxy for total gas column density N-H. By comparing Planck thermal dust data (Release 1.2) and new dust reddening maps from Pan-STARRS 1 and 2MASS, with accurate ...
Polarization in Monte Carlo radiative transfer and dust scattering polarization signatures of spiral galaxies
(EDP Sciences, 2017-05)
Polarization is an important tool to further the understanding of interstellar dust and the sources behind it. In this paper we describe
our implementation of polarization that is due to scattering of light by spherical ...
A multifrequency study of the active star forming region NGC 6357
(Cambridge University Press, 2007)
We investigate the distribution of the ionized, atomic neutral and molecular gas, and of the interstellar dust in the complex star forming region NGC 6357, with the aim of studying the interplay between the massive stars ...
Infrared Spectroscopy of Carbonaceous-chondrite Inclusions in the Kapoeta Meteorite: Discovery of Nanodiamonds with New Spectral Features and Astrophysical Implications
(IOP Publishing, 2018-03-22)
We report the finding of nanodiamonds, coexisting with amorphous carbon, in carbonaceous-chondrite (CC) material from the Kapoeta achondritic meteorite by Fourier-transform infrared (FTIR) spectroscopy and micro-Raman ...
The dust properties and physical conditions of the interstellar medium in the LMC massive star-forming complex N11
(OXFORD UNIV PRESS, 2016)
We combine Spitzer and Herschel data of the star-forming region N11 in the Large Magellanic Cloud (LMC) to produce detailed maps of the dust properties in the complex and study their variations with the interstellar-medium ...
A multiwavelength study of the ring nebula SG 13
(Wiley Blackwell Publishing, Inc, 2009-05)
We investigate the morphology and kinematics of the interstellar medium in the environs of the open cluster Mrk 50, which includes the Wolf–Rayet star WR 157 and a number of early B-type stars. The analysis was performed ...
Angle-dependent radiative grain alignment: Confirmation of a magnetic field – radiation anisotropy angle dependence on the efficiency of interstellar grain alignment
(EDP Sciences, 2011-10)
Context. Interstellar grain alignment studies are currently experiencing a renaissance due to the development of a new quantitativetheory based on radiative alignment torques (RAT). One of the distinguishing predictions ...
Planck intermediate results. XV. A study of anomalous microwave emission in Galactic clouds
(European Southern Observatory., 2014-05-20)
Anomalous microwave emission (AME) is believed to be due to electric dipole radiation from small spinning dust grains. The aim of this paper is
a statistical study of the basic properties of AME regions and the environment ...
On the collisional disalignment of dust grains in illuminated and shaded regions of IC 63
(IOP Publishing, 2021-02)
Interstellar dust grain alignment causes polarization from UV to mm wavelengths, allowing the study of the geometry and strength of the magnetic field. Over the last couple of decades, observations and theory have led to ...
Redistribution of CO at the location of the CO ice line in evolving gas and dust disks
(EDP SCIENCES S A, 2017)
Context. Ice lines are suggested to play a significant role in grain growth and planetesimal formation in protoplanetary disks. Evaporation fronts directly influence the gas and ice abundances of volatile species in the ...
