Cosmic-Ray Diffusion Suppression in Star-forming Regions Inhibits Clump Formation in Gas-rich Galaxies

Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: , , , , | Summary: Observations of the $gamma$-ray emission around star clusters, isolated supernova remnants, and pulsar wind nebulae indicate that the cosmic-ray (CR) diffusion coefficient near acceleration sites can be suppressed by a large factor compared to the Galaxy average. We explore the […]

The Balloon-Borne Large Aperture Submillimeter Telescope Observatory

Kavli Affiliate: Nathan P. Lourie | Summary:The BLAST Observatory is a proposed superpressure balloon-borne polarimeter designed for a future ultra-long duration balloon campaign from Wanaka, New Zealand. To maximize scientific output while staying within the stringent superpressure weight envelope, BLAST will feature new 1.8m off-axis optical system contained within a lightweight monocoque structure gondola. The […]

Characterization, deployment, and in-flight performance of the BLAST-TNG cryogenic receiver

Kavli Affiliate: Nathan P. Lourie | Summary:The Next Generation Balloon-borne Large Aperture Submillimeter Telescope (BLAST-TNG) is a submillimeter polarimeter designed to map interstellar dust and galactic foregrounds at 250, 350, and 500 microns during a 24-day Antarctic flight. The BLAST-TNG detector arrays are comprised of 918, 469, and 272 MKID pixels, respectively. The pixels are […]

W=0 Complex Structure Moduli Stabilization on CM-type K3 x K3 Orbifolds:—Arithmetic, Geometry and Particle Physics—

Kavli Affiliate: Taizan Watari | Summary:It is an important question in string compactification whether complex structure moduli stabilization inevitably ends up with a vacuum expectation value of the superpotential < W > of the order of the Planck scale cubed. Any thoughts on volume stabilization and inflation in string theory, as well as on phenomenology […]

In-flight performance of the BLAST-TNG telescope platform

Kavli Affiliate: Nathan P. Lourie | Summary:The Next Generation Balloon-Borne Large Aperture Submillimeter Telescope (BLAST-TNG) was a unique instrument for characterizing the polarized submillimeter sky at high-angular resolution. BLAST-TNG flew from the Long Duration Balloon Facility in Antarctica in January 2020. Despite the short flight duration, the instrument worked very well and is providing significant […]

Learning Vector Quantized Shape Code for Amodal Blastomere Instance Segmentation

Kavli Affiliate: Daniel Needleman | First 5 Authors: Won-Dong Jang, Donglai Wei, Xingxuan Zhang, Brian Leahy, Helen Yang | Summary: Blastomere instance segmentation is important for analyzing embryos’ abnormality. To measure the accurate shapes and sizes of blastomeres, their amodal segmentation is necessary. Amodal instance segmentation aims to recover the complete silhouette of an object […]
