Breaking the degeneracy between polarization efficiency and cosmological parameters in CMB experiments

Kavli Affiliate: W. L. Kimmy Wu | First 5 Authors: Silvia Galli, W. L. Kimmy Wu, Karim Benabed, François Bouchet, Thomas M. Crawford | Summary: Accurate cosmological parameter estimates using polarization data of the cosmic microwave background (CMB) put stringent requirements on map calibration, as highlighted in the recent results from the Planck satellite. In […]

CharacterGAN: Few-Shot Keypoint Character Animation and Reposing

Kavli Affiliate: Matthew Fisher | First 5 Authors: Tobias Hinz, Matthew Fisher, Oliver Wang, Eli Shechtman, Stefan Wermter | Summary: We introduce CharacterGAN, a generative model that can be trained on only a few samples (8 – 15) of a given character. Our model generates novel poses based on keypoint locations, which can be modified […]

Adiabatic waveforms for extreme mass-ratio inspirals via multivoice decomposition in time and frequency

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Scott A. Hughes, Niels Warburton, Gaurav Khanna, Alvin J. K. Chua, Michael L. Katz | Summary: We compute adiabatic waveforms for extreme mass-ratio inspirals (EMRIs) by "stitching" together a long inspiral waveform from a sequence of waveform snapshots, each of which corresponds to a particular geodesic […]

Two Massive Jupiters in Eccentric Orbits from the TESS Full Frame Images

Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Mma Ikwut-Ukwa, Joseph E. Rodriguez, Samuel N. Quinn, George Zhou, Andrew Vanderburg | Summary: We report the discovery of two short-period massive giant planets from NASA’s Transiting Exoplanet Survey Satellite (TESS). Both systems, TOI-558 (TIC 207110080) and TOI-559 (TIC 209459275), were identified from the 30-minute cadence […]

Quantized and unquantized zero-bias tunneling conductance peaks in Majorana nanowires: Conductance below and above $ 2e^2/h $

Kavli Affiliate: Michael Wimmer | First 5 Authors: Haining Pan, Chun-Xiao Liu, Michael Wimmer, Sankar Das Sarma, | Summary: Majorana zero modes can appear at the wire ends of a 1D topological superconductor and manifest themselves as a quantized zero-bias conductance peak in the tunneling spectroscopy of normal-superconductor junctions. However, in superconductor-semiconductor hybrid nanowires, zero-bias […]
