Special issue of Journal of Quantitative Spectroscopy and Radiative Transfer

Following the well-established ELS practice, we are pleased to solicit papers for a topical issue of the Journal of Quantitative Spectroscopy and Radiative Transfer (JQSRT) and hope that you will want your state-of-the-art research to become part of yet another benchmark collection of papers on electromagnetic scattering and related topics.

This issue will consist only of full-size papers documenting research on the following topics:

150 years of Maxwell`s electromagnetics

new theoretical developments and numerical simulations of light scattering by nonspherical and morphologically complex particles and particle groups

laboratory and field experiments in light scattering by natural and artificial particles

single and multiple light scattering by cloud and aerosol particles in the terrestrial atmosphere

single and multiple scattering of light in various astrophysical objects

light scattering in densely packed particulate media

near-field and coherent effects in light scattering

optical trapping and manipulation

micro and nano-optics

applications of light scattering in remote sensing, particle detection, laboratory and field particle characterization

applications of light scattering methods in biology and biomedicine

light scattering methods to control material properties and technological applications

Your paper does not have to result from an ELS-XV presentation as long as it falls within one or more categories listed above. Each submission will be thoroughly reviewed by at least two independent referees to ensure that all accepted manuscripts satisfy the highest standards of scientific quality adopted for JQSRT. Importantly, this will be a topical issue of JQSRT consisting of full-size papers rather than a conference proceedings volume, which means that extended abstracts of ELS-XV presentations will not be considered.

 

To expedite the communication of your research results to the scientific community at large, our goal is to have the entire special issue published in about 10 months after the conference. This implies a tight review and production schedule. The JQSRT web site has been set up to accommodate your submission. You can submit your

manuscript by going to: http://www.elsevier.com/journals/journal-of-quantitative-spectroscopy-and-radiativetransfer/0022-4073/guide-for-authors and clicking on ``Submit your paper``. You will need to register in order to create a personal account in the new Elsevier on-line editorial system called Evise unless you have done that already.

FULL TIME CIVIL SERVICE POSITION IN RADIATIVE TRANSFER AT NASA GISS, New York, NY

The NASA/GSFC Goddard Institute for Space Studies in Manhattan, NY, is soliciting statements of interest for full-time PhD level civil servant scientist positions for early career through senior levels, in the following area:

Radiative Transfer - We seek a scientist with expertise in the design and development of line-by-line and multiple scattering radiative transfer models of solar and thermal radiation with application to terrestrial-type atmospheres. Specific experience in the use of numerical parameterizations (e.g., k- distributions) and analysis and interpretation of spectral and/or polarimetric measurements are highly desirable, as are interests in terrestrial climate, solar system planets, including exo-planet applications. Also highly desirable are programming skills in FORTRAN and/or similar computer languages.

The above position is intended for civil servant hiring for U.S. citizens. A PhD or equivalent experience in Earth sciences or related discipline is highly desirable. Interested scientists should send a cover letter, curriculum vitae, statements of research interests and names and contact information for three professional references to

Michele.r.ben-gera@nasa.gov by September 30, 2015. A subsequent job application process will be conducted through USAJOBS (www.usajobs.gov ). NASA GSFC is an Equal Opportunity Employer.

Postdoctoral position on debris disks

The Astrophysical Institute and University Observatory (AIU) of the Friedrich Schiller University, Jena, Germany, is seeking candidates for a postdoctoral position.

The position is to work in the Research Unit FOR 2285 ``Debris Disks in Planetary Systems``, newly established by the German Research Foundation (DFG). The successful candidate will join the theory group at the AIU and will work for the Research Unit`s project P3 ``Origin of the warm and hot dust and planetary system architecture``. The project goals are to obtain improved statistics for the occurrence rate and parameters of warm and hot dust disks, to work out plausible scenarios for the origin of the observed warm and hot dust, to derive constraints on planetesimals and planets and the overall architecture of the systems, and to make suggestions for future observational tests.

The postdoc will benefit from close collaboration with other projects of the Research Unit running in Jena, Braunschweig, Hamburg, and Kiel. The position is for three years and can start at any time, but no later than in the early 2016. The salary is standard for postdoc positions in Germany (TV-L E-13 of the German federal public service scale) and includes a number of social and family-related benefits.

The applicants should have a strong educational record and hold a doctoral degree or equivalent in physics or astronomy. Previous experience with astronomical research, preferrably with debris disk and/or exoplanet studies, would be a strong advantage. Applications as a single document in the PDF format should include a CV, a brief statement of research interests, and three names of reference. All applications received by September 30, 2015 will be given full consideration. The Friedrich Schiller University is an equal opportunity employer and explicitely encourages women to apply. Disabled persons with equal aptitude, competence and qualification will be given preference.

Two graduate student positions on debris disks

The Astrophysical Institute and University Observatory (AIU) of the Friedrich Schiller University, Jena, Germany, is seeking candidates for two graduate student positions.

The positions are to work in the Research Unit FOR 2285 ``Debris Disks in Planetary Systems``, newly established by the German Research Foundation (DFG). The successful candidates will join the theory group at the AIU and will work for one of the following two projects.

In the first project (P1, ``Collisional modeling of resolved debris disks``), we plan to extend our knowledge of planetary systems harboring debris disks with the help of state-of-the-art collisional models. Such modeling is a powerful tool to decipher information encrypted in the observed dust and to connect the dust to its parent bodies, directly unobservable planetesimals. Constraints can be placed on locations and masses of planetesimal belts, their size and radial distribution, degree of dynamical excitation, material properties, etc. The graduate student is expected to refine our collisional code, incorporate recent advances from theory and laboratory work, and use the code to study a suite of resolved debris disks.

The second project (P2, ``Sculpturing of debris disks by planets and companions``) aims at modelling of observed asymmetries in debris disks. Common disk features include, for instance, sharp radial boundaries, eccentric offsets, and azimuthal asymmetry. All these are signposts of underlying perturbations that shape the disks. A variety of possible mechanisms have been put forward to explain these phenomena. Many involve the gravitational influence of suggested but yet unseen planets and companions. To study this fascinating connection, the graduate student will combine the dynamical treatment (that describes these perturbations) with the collisional treatment (that describe the dust production) to construct a single numerical model.

Both students will work in close collaboration with other projects of the Research Unit that will provide key ingredients for the collisional models and calculation of observables. They will greatly benefit from the expertise available in the Unit, in general, and our group, in particular. The positions are for three years and can start at any time, but no later than in the early 2016. The salary is standard for postdoc positions in Germany (1/2 TV-L E-13 of the German federal public service scale) and includes a number of social and family-related benefits. The applicants should have a strong educational record and hold Master degree or equivalent in physics or astronomy. Previous experience with numerics and astronomical research, preferably with debris disk and/or exoplanet studies, would be an advantage.

Applications as a single document in the PDF format should include a CV, a brief statement of research interests, and two names of reference. All applications received by September 30, 2015 will be given full consideration. The Friedrich Schiller University is an equal opportunity employer and explicitely encourages women to apply. Disabled persons with equal aptitude, competence and qualification will be given preference.
