Kavli Affiliate: George Efstathiou | First 5 Authors: Itamar Reis, Anastasia Fialkov, Rennan Barkana, , | Summary: We present the evolution of the 21-cm signal from cosmic dawn and the epoch of reionization (EoR) in an upgraded model including three subtle effects of Ly-a radiation: Ly-a heating, CMB heating (mediated by Ly-a photons), and multiple […]
Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Danial Shadmany, Benjamin Lane, Vivishek Sudhir, Nergis Mavalvala, | Summary: Controlling the quadrature measured by a homodyne detector is a universal task in continuous-variable quantum optics. However, deriving an error signal that is linear across theentire range of quadrature angles remains an open experimental problem. Here we […]
Kavli Affiliate: Michael McDonald | First 5 Authors: Taweewat Somboonpanyakul, Michael McDonald, Matthew Bayliss, Mark Voit, Megan Donahue | Summary: We present high-resolution optical images from the Hubble Space Telescope, X-ray images from the Chandra X-ray Observatory, and optical spectra from the Nordic Optical Telescope for a newly-discovered galaxy cluster, CHIPS1911+4455, at z=0.485+/-0.005. CHIPS1911+4455 was […]
Kavli Affiliate: Michael McDonald | First 5 Authors: Taweewat Somboonpanyakul, Michael McDonald, Massimo Gaspari, Brian Stalder, Antony A. Stark | Summary: We present optical follow-up observations for candidate clusters in the Clusters Hiding in Plain Sight (CHiPS) survey, which is designed to find new galaxy clusters with extreme central galaxies that were misidentified as bright […]
Kavli Affiliate: Alan M. Levine | First 5 Authors: Joseph E. Rodriguez, Samuel N. Quinn, George Zhou, Andrew Vanderburg, Louise D. Nielsen | Summary: We present the discovery and characterization of five hot and warm Jupiters — TOI-628 b (TIC 281408474; HD 288842), TOI-640 b (TIC 147977348), TOI-1333 b (TIC 395171208, BD+47 3521A), TOI-1478 b […]
Kavli Affiliate: Paul Alivisatos | First 5 Authors: Burak Guzelturk, Benjamin L. Cotts, Dipti Jasrasaria, John P. Philbin, David A. Hanifi | Summary: Nonradiative processes limit optoelectronic functionality of nanocrystals and curb their device performance. Nevertheless, the dynamic structural origins of nonradiative relaxations in nanocrystals are not understood. Here, femtosecond electron diffraction measurements corroborated by […]
