TOI-431/HIP 26013: a super-Earth and a sub-Neptune transiting a bright, early K dwarf, with a third RV planet

Posted by klaurent MIT

Kavli Affiliate: George Ricker | First 5 Authors: Ares Osborn, David J. Armstrong, Bryson Cale, Rafael Brahm, Robert A. Wittenmyer | Summary: We present the bright (V$_{mag} = 9.12$), multi-planet system TOI-431, characterised with photometry and radial velocities. We estimate the stellar rotation period to be $30.5 pm 0.7$ days using archival photometry and radial […]

$textit{TESS}$ Giants Transiting Giants I: A Non-inflated Hot Jupiter Orbiting a Massive Subgiant

Posted by klaurent MIT

Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Nicholas Saunders, Samuel K. Grunblatt, , , | Summary: While the population of confirmed exoplanets continues to grow, the sample of confirmed transiting planets around evolved stars is still limited. We present the discovery and confirmation of a hot Jupiter orbiting TOI-2184 (TIC 176956893), a massive […]

Optimal multifrequency weighting for CMB lensing

Posted by klaurent Cambridge

Kavli Affiliate: Blake Sherwin | First 5 Authors: Noah Sailer, Emmanuel Schaan, Simone Ferraro, Omar Darwish, Blake Sherwin | Summary: Extragalactic foregrounds in Cosmic Microwave Background (CMB) temperature maps lead to significant biases in CMB lensing reconstruction if not properly accounted for. Combinations of multi-frequency data have been used to minimize the overall map variance […]

The Secret Higgstory of the Highest Temperature during Reheating

Posted by klaurent Chicago

Kavli Affiliate: Wayne Hu | First 5 Authors: Samuel Passaglia, Wayne Hu, Andrew J. Long, David Zegeye, | Summary: We study the role of the Standard Model Higgs condensate, formed during cosmological inflation, in the epoch of reheating that follows. We focus on the scenario where the inflaton decays slowly and perturbatively, so that there […]

Stress tensor mesostructures for freeform shaping of thin substrates

Posted by dbos MIT

Kavli Affiliate: Youwei Yao | First 5 Authors: Youwei Yao, Brandon Chalifoux, Ralf Heilmann, Mark Schattenburg, | Summary: Stress-induced shaping, which deforms thin substrates utilizing stressed surface coatings, has enabled and enhanced a host of applications in past decades. Owing to the touchless fabrication process compatible with modern planar technology, the method has been applied […]
