Large-Scale Spatial Cross-Calibration of Hinode/SOT-SP and SDO/HMI

Posted by klaurent Stanford

Kavli Affiliate: J. Todd Hoeksema | Summary:We investigate the cross-calibration of the Hinode/SOT-SP and SDO/HMI instrument meta-data, specifically the correspondence of the scaling and pointing information. Accurate calibration of these datasets gives the correspondence needed by inter-instrument studies and learning-based magnetogram systems, and is required for physically-meaningful photospheric magnetic field vectors. We approach the problem […]

Revealing AGNs Through TESS Variability

Posted by dbos MIT

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Helena P. Treiber, Jason T. Hinkle, Michael M. Fausnaugh, Benjamin J. Shappee, Christopher S. Kochanek | Summary: We used Transiting Exoplanet Survey Satellite (TESS) data to identify 29 candidate active galactic nuclei (AGNs) through their optical variability. The high-cadence, high-precision TESS light curves present a unique […]

Cosmic Reionization On Computers: Baryonic Effects on Halo Concentrations During the Epoch of Reionization

Posted by klaurent Chicago

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Hanjue Zhu, Nickolay Y. Gnedin, , , | Summary: Baryons both increase halo concentration through adiabatic contraction and expel mass through feedback processes. However, it is not well understood how the radiation fields prevalent during the epoch of reionization affect the evolution of concentration in dark […]

An old warm Jupiter orbiting the metal-poor G-dwarf TOI-5542

Posted by klaurent MIT

Kavli Affiliate: Robert F. Goeke | First 5 Authors: Nolan Grieves, François Bouchy, Solène Ulmer-Moll, Samuel Gill, David R. Anderson | Summary: We report the discovery of a 1.32$^{+0.10}_{-0.10}$ $mathrm{M_{rm Jup}}$ planet orbiting on a 75.12 day period around the G3V $10.8^{+2.1}_{-3.6}$ Gyr old star TOI-5542 (TIC 466206508; TYC 9086-1210-1). The planet was first detected […]

Charge transfer dynamics in MoSe$_{2}$/hBN/WSe$_{2}$ heterostructures

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Yoseob Yoon, Zuocheng Zhang, Kenji Watanabe, Takashi Taniguchi, Sefaattin Tongay | Summary: Ultrafast charge transfer processes provide a facile way to create interlayer excitons and to generate single-cycle THz pulses in directly contacted transition metal dichalcogenide (TMD) layers. More sophisticated heterostructures composed of TMD/hBN/TMD can enable new […]
