Analyzing interferometric observations of strong gravitational lenses with recurrent and convolutional neural networks

Kavli Affiliate: Philip J. Marshall | First 5 Authors: Warren R. Morningstar, Yashar D. Hezaveh, Laurence Perreault Levasseur, Roger D. Blandford, Philip J. Marshall | Summary: We use convolutional neural networks (CNNs) and recurrent neural networks (RNNs) to estimate the parameters of strong gravitational lenses from interferometric observations. We explore multiple strategies and find that […]

Expected Yields of Planet discoveries from the TESS primary and extended missions

Kavli Affiliate: Edward H. Morgan | First 5 Authors: Chelsea X. Huang, Avi Shporer, Diana Dragomir, Michael Fausnaugh, Alan M. Levine | Summary: We present a prediction of the transiting exoplanet yield of the TESS primary mission, in order to guide follow-up observations and science projects utilizing TESS discoveries. Our new simulations differ from previous […]

Planck 2018 results. X. Constraints on inflation

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Planck Collaboration, Y. Akrami, F. Arroja, M. Ashdown, J. Aumont | Summary: We report on the implications for cosmic inflation of the 2018 Release of the Planck CMB anisotropy measurements. The results are fully consistent with the two previous Planck cosmological releases, but have smaller […]

Planck 2018 results. VI. Cosmological parameters

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Planck Collaboration, N. Aghanim, Y. Akrami, M. Ashdown, J. Aumont | Summary: We present cosmological parameter results from the final full-mission Planck measurements of the CMB anisotropies. We find good consistency with the standard spatially-flat 6-parameter $Lambda$CDM cosmology having a power-law spectrum of adiabatic scalar […]

Planck 2018 results. I. Overview and the cosmological legacy of Planck

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Planck Collaboration, Y. Akrami, F. Arroja, M. Ashdown, J. Aumont | Summary: The European Space Agency’s Planck satellite, which was dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the microwave and submillimetre sky continuously between […]

Exclusive production of $B_c$ mesons in $e^+e^-$ colliders

Kavli Affiliate: Dan Luo | First 5 Authors: Yan-Bing Wei, Run-Hui Li, Dan Luo, Cai-Dian Lü, Yue-Long Shen | Summary: Within the framework of the perturbative QCD approach, we calculate the time-like $B_cB_c(B_c^*)$ form factors $F(Q^2)$ and $A_2(Q^2)$. We include relativistic corrections and QCD corrections, either of which can give about $20%$ correction to the […]
