The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems II: A 1 to 20 Micron Spectrum of the Planetary-Mass Companion VHS 1256-1257 b

Posted by dbos September 1, 2022Stanford

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Brittany E. Miles, Beth A. Biller, Polychronis Patapis, Kadin Worthen, Emily Rickman | Summary: We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is a $<$20 M$_mathrm{Jup}$ widely separated ($sim$8arcsec, a = 150 au), young, planetary-mass companion that shares photometric colors […]

GPI 2.0: Characterizing Self-Luminous Exoplanets Through Low-Resolution Infrared Spectroscopy

Posted by dbos August 29, 2022Stanford

Kavli Affiliate: Arlene Aleman | First 5 Authors: Arlene Aleman, Bruce Macintosh, Mary Anne Limbach, Mark Marley, Jeffrey Chilcote | Summary: Direct imaging characterization of extrasolar planets is often done at low spectral resolution. We model the spectrograph for the Gemini Planet Imager upgrade (GPI 2.0) and assess the instrument’s potential for allowing observers to […]

Supercooling of the A phase of $^3$He

Posted by dbos August 25, 2022Cornell

Kavli Affiliate: Jeevak Parpia | First 5 Authors: Yefan Tian, Dmytro Lotnyk, Anna Eyal, Kuang Zhang, Nikolay Zhelev | Summary: Because of the extreme purity, lack of disorder, and complex order parameter, the first-order superfluid $^3$He A-B transition is the leading model system for first order transitions in the early universe. Here we report on […]

Microwave-optics Entanglement via Cavity Optomagnomechanics

Posted by dbos August 23, 2022Delft

Kavli Affiliate: Simon Groblacher | First 5 Authors: Zhi-Yuan Fan, Liu Qiu, Simon Gröblacher, Jie Li, | Summary: Microwave-optics entanglement is a vital component for building hybrid quantum networks. Here, a new mechanism for preparing stationary entanglement between microwave and optical cavity fields in a cavity optomagnomechanical system is proposed. It consists of a magnon […]

Limits and prospects for long-baseline optical fiber interferometry

Posted by dbos August 19, 2022MIT

Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Christopher Hilweg, Danial Shadmany, Philip Walther, Nergis Mavalvala, Vivishek Sudhir | Summary: Today’s most precise optical instruments — gravitational-wave interferometers and optical atomic clocks — rely on long storage times for photons to realize their exquisite sensitivity. Optical fiber technology is the most widely deployed platform for […]

The Atacama Cosmology Telescope: limits on dark matter-baryon interactions from DR4 power spectra

Posted by dbos August 18, 2022Cambridge

Kavli Affiliate: Blake Sherwin | First 5 Authors: Zack Li, Rui An, Vera Gluscevic, Kimberly K. Boddy, J. Richard Bond | Summary: Diverse astrophysical observations suggest the existence of cold dark matter that interacts only gravitationally with radiation and ordinary baryonic matter. Any nonzero coupling between dark matter and baryons would provide a significant step […]
