The James Webb Interferometer: Space-based interferometric detections of PDS 70 b and c at 4.8 $μ$m

Posted by Peking

Kavli Affiliate: Ruobing Dong | First 5 Authors: Dori Blakely, Doug Johnstone, Gabriele Cugno, Anand Sivaramakrishnan, Peter Tuthill | Summary: We observed the planet-hosting system PDS 70 with the James Webb Interferometer, JWST’s Aperture Masking Interferometric (AMI) mode within NIRISS. Observing with the F480M filter centered at 4.8 $mu$m, we simultaneously fit geometrical models to […]

OGLE-2015-BLG-0845L: A low-mass M dwarf from the microlensing parallax and xallarap effects

Posted by dbos April 19, 2024April 29, 2024MIT

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Zhecheng Hu, Wei Zhu, Andrew Gould, Andrzej Udalski, Takahiro Sumi | Summary: We present the analysis of the microlensing event OGLE-2015-BLG-0845, which was affected by both the microlensing parallax and xallarap effects. The former was detected via the simultaneous observations from the ground and Spitzer, and the […]

Improved Thermal Resummation for Multi-Field Potentials

Posted by April 18, 2024Chicago

Kavli Affiliate: Marcela Carena | First 5 Authors: Henning Bahl, Marcela Carena, Aurora Ireland, Carlos E. M. Wagner, | Summary: The resummation of large thermal corrections to the effective potential is mandatory for the accurate prediction of phase transitions. We discuss the accuracy of different prescriptions to perform this resummation at the one- and two-loop […]
