Wind-Informed Rapid Flight-Planning in Complex Urban Topologies via Machine Learning and Experimental Validation

Posted by klaurent Caltech

Kavli Affiliate: Morteza Gharib| Summary:Advanced air mobility operations hold the potential to enhance and expand regional transportation of both people and goods in populated areas. However, hazardous flight conditions arising from interactions between wind and the built environment remain a significant challenge for aerial vehicles in urban settings. This work proposes a novel framework towards […]

SMA Observations Reveal Abundant HNC Chemistry in Transition Disks

Posted by klaurent Peking

Kavli Affiliate: Feng Long| Summary: The physical and chemical conditions of protoplanetary disks shape the properties of nascent planetary systems. The line ratios and relative abundances of the HCN-HNC isomer pair are well-suited for tracing these gas conditions, since isomer chemistry is linked to the underlying temperature, elemental abundances, and irradiation environment of the emitting […]

A Sulfur-Rich Atmosphere for the Young Jupiter Analog AF Lep b Reveals Significant Solid Accretion

Posted by klaurent Caltech

Kavli Affiliate: Dimitri Mawet| Summary:AF Lep b is one of the closest analogs to Jupiter in terms of mass ($3-4~M_rmJup$) and semi-major axis ($9$ AU) amenable to spectroscopic characterization. We present JWST/NIRSpec high-contrast spectroscopy of the planet from $2.85-5.3~μ$m at $Rsim3000$, which provide detections of CO$_2$, H$_2$S, CH$_4$, $^12$CO (and $^13$CO), and H$_2$O, as well […]

Buried germanium quantum well proximitised by magnetic field-resilient superconducting platinum iridium germanosilicide

Posted by klaurent Delft

Kavli Affiliate: Giordano Scappucci | Summary:Hybrid superconductor-semiconductor systems provide a versatile platform for quantum technologies, ranging from superconducting-spin interfaces to topological quantum devices. Progress toward scalable implementations requires superconductors that exhibit high critical fields ($>1$T) at accessible temperatures integrated with low-disorder semiconductor heterostructures. Here we demonstrate a superconducting platinum iridium germanosilicide (PtIrSiGe), with critical out-of-plane […]

Kratos-linerad: GPU-accelerated Monte Carlo radiative transfer of lines with efficient imaging

Posted by klaurent Peking

Kavli Affiliate: Lile Wang |Summary:Spectral lines encode the velocity, the temperature, and the chemical structure of astrophysical gas; interpreting them requires radiative transfer that is accurate at high optical depth, consistent with the local excitation, and efficient enough to synthesize velocity-resolved images. We present Kratos-linerad, a GPU-accelerated Monte Carlo radiative transfer code for spectral lines. […]
