Kavli Affiliate: Saul Rappaport | First 5 Authors: Samuel N. Quinn, Saul Rappaport, Andrew Vanderburg, Jason D. Eastman, Lorne A. Nelson | Summary: We report the detection of a single transit-like signal in the Kepler data of the slightly evolved F star KIC4918810. The transit duration is ~45 hours, and while the orbital period ($Psim10$ […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Sarah Pearson, Susan E. Clark, Alexis J. Demirjian, Kathryn V. Johnston, Melissa K. Ness | Summary: Stellar streams from globular clusters (GCs) offer constraints on the nature of dark matter and have been used to explore the dark matter halo structure and substructure of our Galaxy. […]
Kavli Affiliate: Grace Xing | First 5 Authors: Reet Chaudhuri, Zhen Chen, David Muller, Huili Grace Xing, Debdeep Jena | Summary: High-conductivity undoped GaN/AlN 2D hole gases (2DHGs), the p-type dual of the AlGaN/GaN 2D electron gases (2DEGs), have offered valuable insights into hole transport in GaN and enabled the first GaN GHz RF p-channel […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Sung-Yong Yoon, Jeong-Eun Lee, Seokho Lee, Gregory J. Herczeg, Sunkyung Park | Summary: Outbursts of young stellar objects occur when the mass accretion rate suddenly increases. However, such outbursts are difficult to detect for deeply embedded protostars due to their thick envelope and the rarity of […]
Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Samantha Lynn Stever, Tommaso Ghigna, Mayu Tominaga, Giuseppe Puglisi, Masahiro Tsujimoto | Summary: Systematic effects arising from cosmic rays have been shown to be a significant threat to space telescopes using high-sensitivity bolometers. The LiteBIRD space mission aims to measure the polarised Cosmic Microwave Background with unprecedented […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Wendy L. Freedman, , , , | Summary: Measurement of the distances to nearby galaxies have improved rapidly in recent decades. The ever-present challenge is to reduce systematic effects, especially as greater distances are probed, and the uncertainties become larger. In this paper, we combine several […]
Kavli Affiliate: Subo Dong | First 5 Authors: N. Elias-Rosa, P. Chen, S. Benetti, Subo Dong, J. L. Prieto | Summary: There is a wide consensus that type Ia supernovae (SN Ia) originate from the thermonuclear explosion of CO white dwarfs (WD), with the lack of hydrogen in the observed spectra as a distinctive feature. […]
Kavli Affiliate: Wei Gao | First 5 Authors: Zihao Xiao, Xianfeng Gao, Chilin Fu, Yinpeng Dong, Wei Gao | Summary: Face recognition is greatly improved by deep convolutional neural networks (CNNs). Recently, these face recognition models have been used for identity authentication in security sensitive applications. However, deep CNNs are vulnerable to adversarial patches, which […]
Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Joshua Eby, Satoshi Shirai, Yevgeny V. Stadnik, Volodymyr Takhistov, | Summary: Emission of relativistic axions from transient sources, such as axion star explosions, can lead to observable signatures. We show that axion bursts from collapsing axion stars can be detectable over the wide range of axion […]
Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Joshua Eby, Satoshi Shirai, Yevgeny V. Stadnik, Volodymyr Takhistov, | Summary: Axions constituting dark matter (DM) are often considered to form a non-relativistic oscillating field. We explore bursts of relativistic axions from transient astrophysical sources, such as axion star explosions, where the sources are initially non-relativistic. […]
