Kavli Affiliate: Linhua Jiang | First 5 Authors: Feige Wang, Jinyi Yang, Xiaohui Fan, Joseph F. Hennawi, Aaron J. Barth | Summary: Distant quasars are unique tracers to study the formation of the earliest supermassive black holes (SMBHs) and the history of cosmic reionization. Despite extensive efforts, only two quasars have been found at $zge7.5$, […]
Kavli Affiliate: Peter Graham | First 5 Authors: Benjamin Godfrey, J. Anthony Tyson, Seth Hillbrand, Jon Balajthy, Daniel Polin | Summary: We are building an experiment to search for dark matter in the form of dark photons in the nano- to milli-eV mass range. This experiment is the electromagnetic dual of magnetic detector dark radio […]
Kavli Affiliate: George Ricker | First 5 Authors: David V. Martin, Kareem El-Badry, Vedad Kunovac Hodžić, Amaury H. M. J. Triaud, Ruth Angus | Summary: We present TOI-1259Ab, a 1.0 Rjup gas giant planet transiting a 0.71 Rsun K-dwarf on a 3.48 day orbit. The system also contains a bound white dwarf companion TOI-1259B with […]
Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Yimin Xiao, , , | Summary: The generalized fractional Brownian motion (GFBM) $X:={X(t)}_{tge0}$ with parameters $gamma in [0, 1)$ and $alphain left(-frac12+frac{gamma}{2}, , frac12+frac{gamma}{2} right)$ is a centered Gaussian $H$-self-similar process introduced by Pang and Taqqu (2019) as the scaling limit of power-law shot noise […]
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: Richard Dubois | First 5 Authors: Adam Snyder, Aurelien Barrau, Andrew Bradshaw, Boyd Bowdish, James Chiang | Summary: Electro-optical testing and characterization of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) Camera focal plane, consisting of 205 charge-coupled devices (CCDs) arranged into 21 stand-alone Raft Tower Modules (RTMs) and […]
