Low-loss amorphous dielectric metasurface mirror for precision optical cavities

Posted by klaurent MIT

Kavli Affiliate: Peter Fritschel | Summary:We report the design and experimental realization of a low-loss dielectric metasurface mirror operating at 1064 nm, the primary wavelength of interferometric gravitational-wave detectors. The mirror consists of a single layer of titanium dioxide nanopillars on a glass substrate, achieving high reflectivity via guided-mode resonance. The fabricated mirror has a […]

Minor Structural Differences Tune Functional Specialization of Antenna Subunits in the PSII Energy Transfer Network

Posted by klaurent Berkeley

Kavli Affiliate: Graham Fleming | Summary:Photosystem II (PSII) contains a diverse array of pigment-protein subunits with specialized roles in the antenna network. We investigate the functional significance of this subunit diversity in two structurally similar yet functionally distinct PSII subunits: minor light-harvesting complex CP29 and major light-harvesting complex LHCII. We combine two-dimensional electronic-vibrational spectroscopy with […]

CHAMPS: Data Reduction and Detection of ~3300 Dusty Galaxies at 1.2 mm

Posted by klaurent Tokyo

Kavli Affiliate: John Silverman | Summary:We present the reduction and source catalogs for the textitCOSMOS High-$z$ ALMA-MIRI Population Survey (CHAMPS), the largest Atacama Large (Sub)Millimeter Array (ALMA) blank field survey to date at 0.2,deg$^2$. With observing frequency centered at $250, $GHz ($1.2,$mm) and bandwidth of 7.5 GHz, CHAMPS covers the JWST/NIRCam+MIRI footprint in the COSMOS […]

Is rapid mixing stable?

Posted by klaurent Stanford

Kavli Affiliate: Jordi Montana-Lopez | Summary:Several physically interesting Lindbladians, such as those describing generic open quantum system models as well as engineered state preparation processes, are often rapidly mixing, that is, they relax to steady states in time scaling polylogarithmically with the system size. Owing to the short mixing times, it is physically expected that […]

CHAMPS: The COSMOS High-Redshift ALMA-MIRI Population Survey – A New Census of the Dusty Early Universe

Posted by klaurent Tokyo

Kavli Affiliate: John Silverman | Summary:Understanding how dust forms and evolves over cosmic time is a key open problem in extragalactic astrophysics. Galaxies in the early Universe were once thought to be mostly dust-poor, but recent discoveries of heavily dust-obscured galaxies near the Epoch of Reionization challenge models of early dust production and raise new […]

Toddlers in Resonance I: low masses and eccentricities of the 17 Myr giant planets HIP 67522 bc from transit timing variations

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | Summary:Infant ($<$100,Myr) transiting planet systems provide glimpses into the processes that shape the observed mature planet population. Masses for these planets are powerful data points for testing theories of planet formation and evolution. Because young systems tend to be in mean-motion resonances (MMR) and show higher rates of transit timing […]

COSMOS-3D: Diverse Environments and Hot-dust Signatures among Dusty Star-forming Galaxies at $z$ = 4.9-7.2

Posted by klaurent Peking

Kavli Affiliate: Linhua Jiang | Summary:Dusty star-forming galaxies (DSFGs) are expected to trace early massive-halo assembly, but the connection between dust-obscured star formation, morphology, hot dust, and environment remains unclear at $z$>4. We combine JWST/NIRCam F444W grism spectroscopy from COSMOS-3D with MIRI F1000W/F2100W imaging and a mixed ALMA-selected and ALMA-followed dusty-galaxy sample from CRISTAL, CHAMPS, […]
