TOI-1259Ab — a gas giant planet with 2.7% deep transits and a bound white dwarf companion

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 […]

Exact uniform modulus of continuity and Chung’s LIL for the generalized fractional Brownian motion

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 […]

The subtlety of Ly-a photons: changing the expected range of the 21-cm signal

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 […]

A Novel Modulation Scheme for Homodyne Detection Control

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 […]

Dynamic lattice distortions driven by surface trapping in semiconductor nanocrystals

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 […]
