Optically Pumped AlGaN Double Heterostructure Deep-UV Laser by Molecular Beam Homoepitaxy: Mirror Imperfections and Cavity Loss

Posted by September 22, 2021Cornell

Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Ryan Page, Vladimir Protasenko, Huili, Xing | Summary: We demonstrate the first optically pumped sub-300 nm UV laser structures grown by plasma-assisted molecular beam epitaxy on single-crystal bulk AlN. The edge-emitting laser structures fabricated with the AlN/AlGaN heterostructures exhibit multi-mode emission with peak gain […]

Anomalous elasticity of cellular tissue vertex model

Posted by klaurent September 21, 2021UCSB

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Arthur Hernandez, Michael F. Staddon, Mark J. Bowick, M. Cristina Marchetti, Michael Moshe | Summary: Vertex Models, as used to describe cellular tissue, have an energy controlled by deviations of each cell area and perimeter from target values. The constrained nonlinear relation between area and perimeter […]

The Compton Spectrometer and Imager Project for MeV Astronomy

Posted by September 21, 2021Tokyo

Kavli Affiliate: Tom Melia | First 5 Authors: John A. Tomsick, Steven E. Boggs, Andreas Zoglauer, Eric Wulf, Lee Mitchell | Summary: The Compton Spectrometer and Imager (COSI) is a 0.2-5 MeV Compton telescope capable of imaging, spectroscopy, and polarimetry of astrophysical sources. Such capabilities are made possible by COSI’s germanium cross-strip detectors, which provide […]

Formation and evolution of young massive clusters in galaxy mergers: the SMUGGLE view

Posted by klaurent September 21, 2021MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Hui Li, Mark Vogelsberger, Greg L. Bryan, Federico Marinacci, Laura V. Sales | Summary: Galaxy mergers are known to host abundant young massive cluster (YMC) populations, whose formation mechanism is still not well-understood. Here, we present a high-resolution galaxy merger simulation with explicit star formation and stellar […]

AutoGCL: Automated Graph Contrastive Learning via Learnable View Generators

Posted by klaurent September 21, 2021Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Yihang Yin, Qingzhong Wang, Siyu Huang, Haoyi Xiong, Xiang Zhang | Summary: Contrastive learning has been widely applied to graph representation learning, where the view generators play a vital role in generating effective contrastive samples. Most of the existing contrastive learning methods employ pre-defined view generation methods, […]

Hyper Suprime-Cam Subaru Strategic Program: A Mass-Dependent Slope of the Galaxy Size-Mass Relation at $z<1$

Posted by klaurent September 20, 2021Tokyo

Kavli Affiliate: Naoki Yasuda | First 5 Authors: Lalitwadee Kawinwanichakij, John D. Silverman, Xuheng Ding, Angelo George, Ivana Damjanov | Summary: We present the galaxy size-mass ($R_{e}-M_{ast}$) distributions using a stellar-mass complete sample of $sim1.5$ million galaxies, covering $sim100$ deg$^2$, with $log(M_{ast}/M_{odot})>10.2~(9.2)$ over the redshift range $0.2<z<1.0$ $(z<0.6)$ from the second public data release of […]
