Kilonova and Optical Afterglow from Binary Neutron Star Mergers. II. Optimal Search Strategy for Serendipitous Observations and Target-of-opportunity Observations of Gravitational-wave Triggers

Posted by klaurent October 20, 2021Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Jin-Ping Zhu, Shichao Wu, Yuan-Pei Yang, Chang Liu, Bing Zhang | Summary: In the second work of this series, we explore the optimal search strategy for serendipitous and gravitational-wave-triggered target-of-opportunity (ToO) observations of kilonovae and optical short-duration gamma-ray burst (sGRB) afterglows from binary neutron star (BNS) mergers, […]

Machine Learning for Continuous Quantum Error Correction on Superconducting Qubits

Posted by October 20, 2021Berkeley

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Ian Convy, Haoran Liao, Song Zhang, Sahil Patel, William P. Livingston | Summary: We propose a machine learning algorithm for continuous quantum error correction that is based on the use of a recurrent neural network to identity bit-flip errors from continuous noisy syndrome measurements. The algorithm […]

TOI-2285b: A 1.7 Earth-radius Planet Near the Habitable Zone around a Nearby M Dwarf

Posted by klaurent October 19, 2021MIT

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Akihiko Fukui, Tadahiro Kimura, Teruyuki Hirano, Norio Narita, Takanori Kodama | Summary: We report the discovery of TOI-2285b, a sub-Neptune-sized planet transiting a nearby (42 pc) M dwarf with a period of 27.3 days. We identified the transit signal from the Transiting Exoplanet Survey Satellite photometric data, […]

Precision analysis of the redshift-space galaxy bispectrum

Posted by klaurent October 19, 2021Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Mikhail M. Ivanov, Oliver H. E. Philcox, Takahiro Nishimichi, Marko Simonović, Masahiro Takada | Summary: We study the information content of the angle-averaged (monopole) redshift space galaxy bispectrum. The main novelty of our approach is the use of a systematic tree-level perturbation theory model that includes galaxy […]

Momentum deposition of supernovae with cosmic rays

Posted by klaurent October 19, 2021Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Francisco Rodríguez Montero, Sergio Martin-Alvarez, Debora Sijacki, Adrianne Slyz, Julien Devriendt | Summary: The cataclysmic explosions of massive stars as supernovae are one of the key ingredients of galaxy formation. However, their evolution is not well understood in the presence of magnetic fields or cosmic rays (CRs). […]

One-loop Gluon Amplitudes in AdS

Posted by klaurent October 19, 2021UCAS

Kavli Affiliate: Xinan Zhou | First 5 Authors: Luis F. Alday, Agnese Bissi, Xinan Zhou, , | Summary: We initiate the study of one-loop gluon amplitudes in AdS space. These amplitudes were recently computed at tree level for a variety of backgrounds of the form $AdS_{d+1} times S^3$. For concreteness, we compute the one-loop correction […]

Full tunability enabled by Floquet engineering in a multilevel quantum dot system

Posted by klaurent October 19, 2021Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Yuan Zhou, Sisi Gu, Ke Wang, Gang Cao, Xuedong Hu | Summary: Tunability of an artificial quantum system is crucial to its capability to process quantum information. However, tunability usually poses significant demand on the design and fabrication of a device. In this work, we demonstrate that […]

The Simons Observatory: Constraining inflationary gravitational waves with multi-tracer B-mode delensing

Posted by October 19, 2021Tokyo

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Anton Baleato Lizancos, Naomi Robertson, Blake D. Sherwin, Anthony Challinor | Summary: We introduce and validate a delensing framework for the Simons Observatory (SO), which will be used to improve constraints on inflationary gravitational waves (IGWs) by reducing the lensing noise in measurements of the […]

Valley transport driven by dynamic lattice distortion

Posted by klaurent October 19, 2021UCAS

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Yuya Ominato, Daigo Oue, Mamoru Matsuo, , | Summary: Angular momentum conversion between mechanical rotation and the valley degree of freedom in 2D Dirac materials is investigated theoretically. Coupling between the valley and vorticity of dynamic lattice distortions is derived by applying the k.p method to 2D […]

TESS Hunt for Young and Maturing Exoplanets (THYME) VI: an 11 Myr giant planet transiting a very low-mass star in Lower Centaurus Crux

Posted by klaurent October 18, 2021MIT

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Andrew W. Mann, Mackenna L. Wood, Stephen P. Schmidt, Madyson G. Barber, James E. Owen | Summary: Mature super-Earths and sub-Neptunes are predicted to be $simeq$Jovian radius when younger than 10 Myr. Thus, we expect to find 5-15$R_oplus$ planets around young stars even if their older counterparts […]
