Rcosmo: R Package for Analysis of Spherical, Healpix and Cosmological Data Arxiv:1907.05648V1 [Stat.CO] 12 Jul 2019
CONTRIBUTED RESEARCH ARTICLE 1 rcosmo: R Package for Analysis of Spherical, HEALPix and Cosmological Data Daniel Fryer, Ming Li, Andriy Olenko Abstract The analysis of spatial observations on a sphere is important in areas such as geosciences, physics and embryo research, just to name a few. The purpose of the package rcosmo is to conduct efficient information processing, visualisation, manipulation and spatial statistical analysis of Cosmic Microwave Background (CMB) radiation and other spherical data. The package was developed for spherical data stored in the Hierarchical Equal Area isoLatitude Pixelation (Healpix) representation. rcosmo has more than 100 different functions. Most of them initially were developed for CMB, but also can be used for other spherical data as rcosmo contains tools for transforming spherical data in cartesian and geographic coordinates into the HEALPix representation. We give a general description of the package and illustrate some important functionalities and benchmarks. Introduction Directional statistics deals with data observed at a set of spatial directions, which are usually positioned on the surface of the unit sphere or star-shaped random particles. Spherical methods are important research tools in geospatial, biological, palaeomagnetic and astrostatistical analysis, just to name a few. The books (Fisher et al., 1987; Mardia and Jupp, 2009) provide comprehensive overviews of classical practical spherical statistical methods. Various stochastic and statistical inference modelling issues are covered in (Yadrenko, 1983; Marinucci and Peccati, 2011). The CRAN Task View Spatial shows several packages for Earth-referenced data mapping and analysis. All currently available R packages for spherical data can be classified in three broad groups. The first group provides various functions for working with geographic and spherical coordinate systems and their visualizations. -

Measuring Inflation with CLASS
Measuring Inflation with CLASS by Dominik Gothe A dissertation submitted to Johns Hopkins University in conformity with the requirements for the degree of Doctor of Philosophy. July 2015 Baltimore, Maryland c Dominik Gothe All rights reserved Abstract Using the Cosmology Large Angular Scale Surveyor (CLASS), we will measure the po- larization of the Cosmic Microwave Background (CMB) to constrain inflationary theory. The gravitational waves generated during the inflationary epoch imprinted specific polar- ization patterns – quantifiable by tensor-to-scalar ratio r – onto the CMB, which CLASS is designed to detect. Furthermore, we will be able to make assertions about the energy scale during inflation by discovering the features of the polarization power spectrum, providing a probe into physics of energy scales not conceivable in particle-accelerator physics. CLASS is a unique ground based experiment with extensive consideration given to mitigating sys- tematic uncertainties. A brief introduction into inflationary cosmology and review of current scientific results will be presented in the light of the upcoming measurements with the newly built CLASS de- tector. I will detail some of my technical contribution to the construction of this telescope. I have conducted my research under the advise of Prof. Bennett. Additionally the thesis was reviewed by Prof. Marriage, Prof. Kamionkowski, Prof. Chuss, and Prof. Strobel. ii Acknowledgments I would like to thank my wife, friends, members of the Johns Hopkins community, my mentors, teachers, supervisors, and dissertation committee.

How can we hack the Anthropocene to create the Aerocene? The first Aerocene Campus is an open invitation to explore, extend and imagine the Aerocene Epoch through the sculpture of the Aerocene Explorer. The Campus asks how community- driven practices with the Aerocene Explorer can inform environmental, social and mental ecologies in post-Anthropocenic worlds. On November 26th, experts from a wide range of disciplines will gather together for a full day of provocation, discussion, collaboration and 'hacking' to experiment with the Aerocene Explorer and to co-create the Aerocene epoch. To hack is to creatively overcome the limitations of a system, to improve or subvert the intentions of its original form in a spirit of playfulness and exploration. -

Refueling the Magic Furnace: Kilonova 2017 Rewrites the Story of Element Origins
Refueling the Magic Furnace: Kilonova 2017 Rewrites the Story of Element Origins Barry Wood University of Houston Abstract For more than half a century, we have understood element creation in the stars—described in Marcus Chown’s colorful image as “the magic furnace.” From 1958 until 2017, supernova explosions were thought to be the primary site of element creation above Iron, No. 26 on the Periodic Table. This assumption was radically overturned with the August 17, 2017, arrival of signals from a catastrophic collision of neutron stars. This paper traces the history of element-creation science leading to the striking discoveries attending “Kilonova 2017” that now call for a rewriting of the nucleosynthesis chapter of Big History.

View as a Web page ABOUT TALARC | JOIN TALARC | HAM RADIO EVENTS | LEGIONTOWN | CONTACT US American Legion Birthday to be celebrated worldwide, March 11, on shortwave radio Dear TALARC Members and Friends, March 15 is the designated birthday of The American Legion. It is the day in 1919 when the first American Legion caucus, held by members of the American Expeditionary Force, convened in Paris. Much as the birthday of the United States is celebrated on July 4 – for the day in 1776 when rebelling patriots declared the independence of the British colonies and the spirit of America was born – March 15 is the day on which the Legion came to life. Each year, Legion posts across the country hold events – public, private or both – to commemorate this anniversary. At the National Headquarters of The American Legion there also is an event conducted annually to observe the Legion birthday, and on a worldwide scale. Members of The American Legion Amateur Radio Club (TALARC) will operate a special event station to commemorate the Legion’s 98th birthday. Operating from the radio room at National Headquarters in Indianapolis, ham radio operators at club station K9TAL will celebrate the Legion’s 98 years of service to America’s veterans with both members and non-member amateur radio operators around the world on Saturday, March 11, 2017. Ham radio operators wishing to contact Special Event Station K9TAL should tune to 40 meters: 7.225 MHz (+/- 5 KHz) LSB; or to 2 meters: K9DC 147.315 Repeater at Indianapolis; or IRLP Node 9735; or, to EchoLink *CROSSRDS* Conference node. -
