High-coherence hybrid-integrated 780 nm source by self-injection-locked second-harmonic generation in a high-Q silicon-nitride resonator

Posted by klaurent June 19, 2023Caltech

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Bohan Li, Zhiquan Yuan, Warren Jin, Lue Wu, Joel Guo | Summary: By self-injection-locking a 1560 nm distributed feedback semiconductor laser to a high-$Q$ silicon nitride resonator, a high-coherence 780 nm second harmonic signal is generated via the photogalvanic-induced second-order nonlinearity. A record-low frequency noise floor […]

A note on varieties of weak CM-type

Posted by dbos June 17, 2023Tokyo

Kavli Affiliate: Taizan Watari | First 5 Authors: Masaki Okada, Taizan Watari, , , | Summary: CM-type projective varieties X of complex dimension n are characterized by their CM-type rational Hodge structures on the cohomology groups. One may impose such a condition in a weakest form when the canonical bundle of X is trivial; the […]

No thick carbon dioxide atmosphere on the rocky exoplanet TRAPPIST-1 c

Posted by dbos June 16, 2023Stanford

Kavli Affiliate: Laura Schaefer | First 5 Authors: , , , , | Summary: Seven rocky planets orbit the nearby dwarf star TRAPPIST-1, providing a unique opportunity to search for atmospheres on small planets outside the Solar System (Gillon et al., 2017). Thanks to the recent launch of JWST, possible atmospheric constituents such as carbon […]

Outshining by Recent Star Formation Prevents the Accurate Measurement of High-z Galaxy Stellar Masses

Posted by dbos June 16, 2023MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Desika Narayanan, Sidney Lower, Paul Torrey, Gabriel Brammer, Weiguang Cui | Summary: In this paper, we demonstrate that the inference of galaxy stellar masses via spectral energy distribution (SED) fitting techniques for galaxies formed in the first billion years after the Big Bang carries fundamental uncertainties owing […]

Filamentary Dust Polarization and the Morphology of Neutral Hydrogen Structures

Posted by dbos June 16, 2023Stanford

Kavli Affiliate: Susan E. Clark | First 5 Authors: George Halal, Susan E. Clark, Ari Cukierman, Dominic Beck, Chao-Lin Kuo | Summary: Filamentary structures in neutral hydrogen (HI) emission are well aligned with the interstellar magnetic field, so HI emission morphology can be used to construct templates that strongly correlate with measurements of polarized thermal […]
