We present six nearly full-sky maps made from data taken by radiometers on the Juno satellite during its 5 yr flight to Jupiter. The maps represent integrated emission over ∼4% passbands spaced approximately in octaves between 600 MHz and 21.9 GHz. Long-timescale offset drifts are removed in all bands, and, for the two lowest-frequency bands, gain drifts are also removed from the maps via a self-calibration algorithm similar to the NPIPE pipeline used by the Planck Collaboration. We show that, after this solution is applied, statistical noise in the maps is consistent with thermal radiometer noise and expected levels of correlated noise on the gain and noise drift solutions. We verify our map solutions with several consistency tests and end-to-end simulations. We also estimate the level of systematic pixelization noise and polarization leakage via simulations.

SPHEREx, the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and ices Explorer, is a NASA MIDEX mission planned for launch in 2024. SPHEREx will carry out the first all-sky spectral survey at wavelengths between 0.75µm and 5µm with spectral resolving power ~40 between 0.75 and 3.8µm and ~120 between 3.8 and 5µm At the end of its two-year mission, SPHEREx will provide 0.75-to-5µm spectra of each 6."2x6."2 pixel on the sky - 14 billion spectra in all. This paper updates an earlier description of SPHEREx presenting changes made during the mission's Preliminary Design Phase, including a discussion of instrument integration and test ow and a summary of the data processing, analysis, and distribution plans.

This study falls within the scope of the fatigue design of handling machines manufactured by the Manitou Group, which are usually composed of a chassis and a boom. These welded assemblies are subjected to fatigue loading conditions and include highly stressed zones acting as crack initiation sites. In view of the geometrical complexity of the structures, the degree of conservatism incorporated in design methods based on the usual international standards is difficult to evaluate. Alternative design approaches based on the structural stress are being developed and used by other companies such as PSA and LOHR. The present work focuses on developing a numerical approach to take into account the local stiffness of welds. The proposed strategy is based on shell finite element modelling of the assembly and an equivalent stiffness matrix for welds. This makes it possible to describe the local mechanical behaviour of seam welds with the computational cost of a shell element based model. To validate the proposed approach, a comparison in terms of stiffness is undertaken for three welded structures using solid finite element models as a reference. The proposed approach is also compared to the Manitou, Fayard and Lohr approaches.

This white paper addresses key challenges for the design of next-decade Cosmic Microwave Background (CMB) experiments and for assessing their capability to extract cosmological information from CMB polarization. We argue that it is critical to develop more robust analysis and simulation tools if any of these experiments is to realize its promise.

Joint WFIRST/Subaru observations have the potential to enable transformative science that cannot be done by either telescope alone. WFIRST will image the near-infrared sky to unprecedented depth and area. Subaru, with its wide field and unique instruments for both imaging and spectroscopy, is a superb complement.

Aspen Center for Physics Project Summary DE-SC0007313 Budget Period: 1/1/2012 to 12/31/2012 The Hunt for New Particles, from the Alps to the Plains to the Rockies The 2012 Aspen Winter Conference on Particle Physics was held at the Aspen Center for Physics from February 11 to February 17, 2012. Sixty-seven participants from nine countries, and several universities and national labs attended the workshop titled, The Hunt for New Particles, from the Alps to the Plains to the Rockies. There were 53 formal talks, and a considerable number of informal discussions held during the week. The weeks events included a public lecture-Hunting the Dark Universe given by Neal Weiner from New York University) and attended by 237 members of the public, and a physics cafe geared for high schoolers that is a discussion with physicists conducted by Spencer Chang (University of Oregon), Matthew Reece (Harvard University) and Julia Shelton (Yale University) and attended by 67 locals and visitors. While there were no published proceedings, some of the talks are posted online and can be Googled. The workshop was organized by John Campbell (Fermilab), Patrick Fox (Fermilab), Ivan Furic (University of Florida), Eva Halkiadakis (Rutgers University) and Daniel Whiteson (University of California Irvine).

Inflationary Theory and its Confrontation with Data in the Planck Era The 2012 Aspen Winter Conference on Astroparticle physics held at the Aspen Center for Physics was Inflationary Theory and its Confrontation with Data in the Planck Era. It was held from January 30 to February 4, 2012. The 62 participants came from 7 countries and attended 43 talks over five days. Late mornings through the afternoon are reserved for informal discussions. In feedback received from participants, it is often these unplanned chats that produce the most excitement due to working through problems with fellow physicists from other institutions and countries or due to incipient collaborations. In addition, Shamit Kachru of Stanford University gave a public lecture titled The Small (and Large) Scale Structure of Space-Time.There were 237 members of the general public in attendance. Before the lecture, 65 people attended the physics cafe to discuss the current topic with Matthew Kleban (New York University) and Chao-Lin Kuo (Stanford University). This workshop was organized by Olivier Dore (Jet Propulsion Lab), Fabian Schmidt (Caltech), Leonardo Senatore (Stanford University), and Kendrick Smith (Princeton University).

Gravitational lensing of the cosmic microwave background by large-scale structure in the late universe is both a source of cosmological information and a potential contaminant of primordial gravity waves. Because lensing imprints growth of structure in the late universe on the CMB, measurements of CMB lensing will constrain parameters to which the CMB would not otherwise be sensitive, such as neutrino mass. If the instrumental noise is sufficiently small (<~ 5 uK-arcmin), the gravitational lensing contribution to the large-scale B-mode will be the limiting source of contamination when constraining a stochastic background of gravity waves in the early universe, one of the most exciting prospects for future CMB polarization experiments. High-sensitivity measurements of small-scale B-modes can reduce this contamination through a lens reconstruction technique that separates the lensing and primordial contributions to the B-mode on large scales. A fundamental design decision for a future CMB polarization experiment such as CMBpol is whether to have coarse angular resolution so that only the large-scale B-mode (and the large-scale E-mode from reionization) is measured, or high resolution to additionally measure CMB lensing. The purpose of this white paper is to evaluate the science case for CMB lensing in polarization: constraints on cosmological parameters, increased sensitivity to the gravity wave B-mode via lens reconstruction, expected level of contamination from non-CMB foregrounds, and required control of beam systematics.
