Infrared polarimetry and the magnetic field in external galaxies

Here researchers report for the first time infrared polarimetry of the normal edge on spiral NGC 4565 and the interacting pair NGC 3690/IC 694 (Arp 299). These observations, as well as previous observations, were made with the Minnesota Infrared Polarimeter on the Space Infrared Telescope Facility during the past year. The goal is to explore the magnetic field geometry in these galaxies and to determine the extent to which the field is ordered and uniform

Polarimetry in the Visible and Infrared: Application to CMB Polarimetry

Interstellar polarization from aligned dust grains can be measured both in transmission at visible and near-infrared wavelengths and in emission at far-infrared and sub-mm wavelengths. These observations can help predict the behavior of foreground contamination of CMB polarimetry by dust in the Milky Way. Fractional polarization in emission from aligned dust grains will be at the higher range of currently observed values of 4-10%. Away from the galactic plane, fluctuations in Q and U will be dominated by fluctuations in intensity, and less influenced by fluctuations in fractional polarization and position angle.Comment: To be published in the proceedings of "The Cosmic Microwave Background and its Polarization", New Astronomy Reviews, (eds.

Undocumented: The Stress of Status

From 2010 to 2012 researchers from Fairfield University, Loyola University Chicago, and Santa Clara University talked to students who were undocumented and attending Jesuit colleges. The project culminated in a book, Undocumented and in College: Students and Institutions in a Climate of National Hostility (Fordham University Press, 2017)

PREDICTING FEEDING COST OF GAIN WITH MORE PRECISION

Costs during the feeding period, commonly summarized as "feeding cost of gain", are primary determinants of cattle feeding profits. This study provides a method of generalizing information available at placement time into a suitable feeding cost of gain prediction, so that feeders and ranchers can make more informed placement decisions.Cattle-Feeding, Feeding-Cost-Of-Gain, Industrial Organization, Livestock Production/Industries,

Blacks in the American Criminal Justice System: A Study of Sanctioned Deviance

Almost since the beginning of Black history in America there have been differences of opinion as to what the role of Blacks should be in reference to the criminal justice system. In the beginning these differences centered around the issue of cooperation or resistance to the slave system and a criminal justice system that guaranteed slavery durante vita. Now, while the issue is no longer slavery, Blacks continue the debate over cooperation versus resistance to the criminal justice system. What should the role of Blacks be in reference to the criminal justice system? Can Blacks be of greater assistance to other Blacks by working within the system? Does working within this system imply support for it? Is resistance to the system a viable alternative to Blacks? Are there realistic alternatives to the present criminal justice system? Do Blacks have a choice as to what their role is or will be in this system? The pages that follow address the very complicated issue of Black involvement in a criminal justice system that many have labeled as inimical to Black development in America
