Radio Supernovae in the Local Universe
Atish Kamble, Alicia Soderberg, Edo Berger +3
In the last three decades, about 50 radio supernovae have been detected as a result of targeted searches of optically discovered supernovae in the local universe. Despite this rela…
Magnetism in the Brown Dwarf Regime
Melodie M. Kao, J. Sebastian Pineda, Peter Williams +8
A suite of discoveries in the last two decades demonstrate that we are now at a point where incorporating magnetic behavior is key for advancing our ability to characterize substel…
High-Precision APT Malware Attribution with Out-of-Scope Resilience
Peter Williams, Adam Sobey, Erisa Karafili
Early attribution of Advanced Persistent Threat (APT) activity can help defenders prioritise investigation, select countermeasures, and reduce the impact of an intrusion. Malware p…
QCD Corrections to Higgs Pair Production in Bottom Quark Fusion
Sally Dawson, Chung Kao, Yili Wang +1
We present a complete next-to-leading order (NLO) calculation for the total cross section of inclusive Higgs pair production via bottom-quark fusion () at the CERN…
Explosive Growth in Large-Scale Collaboration Networks
Peter Williams, Zhan Chen
We analyse the evolution of two large collaboration networks: the Microsoft Academic Graph (1800-2020) and Internet Movie Database (1900-2020), comprising and $1…
EarthFinder Probe Mission Concept Study: Characterizing nearby stellar exoplanet systems with Earth-mass analogs for future direct imaging
Peter Plavchan, Gautam Vasisht, Chas Beichman +52
EarthFinder is a NASA Astrophysics Probe mission concept selected for study as input to the 2020 Astrophysics National Academies Decadal Survey. The EarthFinder concept is based on…
Scientific opportunies for bERLinPro 2020+, report with ideas and conclusions from bERLinProCamp 2019
Thorsten Kamps, Michael Abo-Bakr, Andreas Adelmann +38
The Energy Recovery Linac (ERL) paradigm offers the promise to generate intense electron beams of superior quality with extremely small six-dimensional phase space for many applica…
Parametric Analysis of Network Evolution Processes
Peter Williams, Zhan Chen
We present a comprehensive parametric analysis of node and edge lifetimes processes in two large-scale collaboration networks: the Microsoft Academic Graph (1800-2020) and Internet…
The Development of Energy-Recovery Linacs
Chris Adolphsen, Kevin Andre, Deepa Angal-Kalinin +46
Energy-recovery linacs (ERLs) have been emphasised by the recent (2020) update of the European Strategy for Particle Physics as one of the most promising technologies for the accel…
Preliminary Results of the CASCADE Hidden Sector Photon Search
Nathan Woollett, Ian Bailey, Graeme Burt +10
Light shining through a wall experiments can be used to make measurements of photon-WISP couplings. The first stage of the CASCADE experiment at the Cockcroft Institute of Accelera…
Population mixtures and searches of lensed and extended quasars across photometric surveys
Peter Williams, Adriano Agnello, Tommaso Treu
Wide-field photometric surveys enable searches of rare yet interesting objects, such as strongly lensed quasars or quasars with a bright host galaxy. Past searches for lensed quasa…
A Modular Path Length Corrector for Recirculating Linacs
Hywel Owen, Peter Williams
We present a novel modular magnetic system that can introduce a large and continuously-variable path length difference without simultaneous variation of the longitudinal dispersion…
Astronomy Career Profiles from the AAS Newsletter Archives
Travis Metcalfe, Leila Belkora, Liam McDaid +8
This is a collection of articles that were originally published in the Newsletter of the American Astronomical Society (AAS) between May 2008 and September 2011 by the Committee on…
Arc and Chicane Bunch Compression Schemes for Hard and Soft X-Ray Free Electron Laser Facilities: A Comparison
Adam Dixon, Peter Williams, Sara Thorin +4
X-ray free-electron laser (XFEL) facilities require progressive compression of electron bunches as they are accelerated from an injector to the undulators. This is necessary to ach…
HERA Phase I Limits on the Cosmic 21-cm Signal: Constraints on Astrophysics and Cosmology During the Epoch of Reionization
The HERA Collaboration, Zara Abdurashidova, James E. Aguirre +81
Recently, the Hydrogen Epoch of Reionization Array (HERA) collaboration has produced the experiment's first upper limits on the power spectrum of 21-cm fluctuations at z~8 and 10.…
Intermittent Jolts of Galactic UV Radiation: Mutagenetic Effects
John M. Scalo, J. Craig Wheeler, Peter Williams
We estimate the frequency of intermittent hypermutation events and disruptions of planetary/satellite photochemistry due to ultraviolet radiation from core collapse supernova explo…
