Astro2020 APC White Paper: The need for better tools to design future CMB experiments
G. Rocha, A. J. Banday, R. Belen Barreiro +27
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 in…
No Higher Criticism of the Bianchi Corrected WMAP Data
L. Cayon, A. J. Banday, T. Jaffe +4
Motivated by the success of the Bianchi VII_h model in addressing many of the anomalies observed in the WMAP data (Jaffe et al.), we present calculations in real and in wavelet spa…
A Unified Model for the Fan Region and the North Polar Spur: A bundle of filaments in the Local Galaxy
J. L. West, T. L. Landecker, B. M. Gaensler +2
We present a simple, unified model that can explain two of the brightest, large-scale, diffuse, polarized radio features in the sky, the North Polar Spur (NPS) and the Fan Region,…
Planck pre-launch status: the Planck-LFI programme
N. Mandolesi, M. Bersanelli, R. C. Butler +140
This paper provides an overview of the Low Frequency Instrument (LFI) programme within the ESA Planck mission. The LFI instrument has been developed to produce high precision maps…
Helicity in the Large-Scale Galactic Magnetic Field
J. L. West, R. N. Henriksen, K. Ferrière +4
We search for observational signatures of magnetic helicity in data from all-sky radio polarization surveys of the Milky Way Galaxy. Such a detection would help confirm the dynamo…
Cygnus Loop: A double bubble?
J. West, S. Safi-Harb, I. Reichardt +4
The Cygnus Loop is a well-studied supernova remnant (SNR) that has been observed across the electromagnetic spectrum. Although widely believed to be an SNR shell with a blow- out r…
SKA studies of in-situ synchrotron radiation from molecular clouds
Clive Dickinson, R. Beck, R. Crocker +16
Observations of the properties of dense molecular clouds are critical in understanding the process of star-formation. One of the most important, but least understood, is the role o…
Legacy Archive for Microwave Background Data Analysis (LAMBDA): An Overview
G. E. Addison, T. M. Essinger-Hileman, M. R. Greason +5
This is an overview of the data products and other resources available through NASA's LAMBDA site https://lambda.gsfc.nasa.gov/. An up-to-date version of this document, along with…
X-ray Observations of BL Lacertae During 1997 Outburst and its Association with Quasar-like Characteristics
G. Madejski, M. Sikora, T. Jaffe +3
This paper reports on the X-ray emission from BL Lacertae during its July 1997 outburst as observed with the Rossi X-ray Timing Explorer (RXTE), compares the RXTE data to previous…
When disorder looks like order: a new model to explain radial magnetic fields in young supernova remnants
J. L. West, T. Jaffe, G. Ferrand +2
Radial magnetic fields are observed in all known young, shell-type supernova remnants (SNRs) in our Galaxy, including Cas A, Tycho, Kepler, and SN1006 and yet the nature of these r…
The Connection between Supernova Remnants and the Galactic Magnetic Field: A Global Radio Study of the Axisymmetric Sample
J. L. West, S. Safi-Harb, T. Jaffe +3
The study of supernova remnants (SNRs) is fundamental to understanding the chemical enrichment and magnetism in galaxies, including our own Milky Way. In an effort to understand th…
Characterization of the L 98-59 multi-planetary system with HARPS: two confirmed terrestrial planets and a mass upper limit on the third
R. Cloutier, N. Astudillo-Defru, X. Bonfils +33
L 98-59 (TIC 307210830, TOI-175) is a nearby M3 dwarf around which TESS revealed three terrestrial-sized transiting planets (0.80, 1.35, 1.57 Earth radii) in a compact configuratio…
Simulating polarized Galactic synchrotron emission at all frequencies, the Hammurabi code
A. Waelkens, T. Jaffe, M. Reinecke +2
We present a publicly available code called Hammurabi for generating mock polarized observations of Galactic synchrotron emission for telescopes like LOFAR, SKA, Planck and WMAP, b…
Opportunities for Multimessenger Astronomy in the 2020s
E. Burns, A. Tohuvavohu, J. M. Bellovary +22
Electromagnetic observations of the sky have been the basis for our study of the Universe for millennia, cosmic ray studies are now entering their second century, the first neutrin…
