Simulations of systematic effects arising from cosmic rays in the LiteBIRD space telescope, and effects on the measurements of CMB $B$-modes

Posted by klaurent June 30, 2021Tokyo

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 […]

Measurements of the Hubble Constant: Tensions in Perspective

Posted by klaurent June 29, 2021Chicago

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 […]

Nebular Halpha emission in SN Ia 2016jae

Posted by klaurent June 29, 2021Peking

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. […]

Improving Transferability of Adversarial Patches on Face Recognition with Generative Models

Posted by klaurent June 29, 2021Caltech

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 […]

Probing Relativistic Axions from Transient Astrophysical Sources

Posted by June 28, 2021Tokyo

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. […]

Probing Relativistic Axions from Transient Astrophysical Sources

Posted by klaurent June 28, 2021Tokyo

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 […]

The Simons Observatory microwave SQUID multiplexing detector module design

Posted by June 28, 2021Chicago

Kavli Affiliate: Jeffrey J. McMahon | First 5 Authors: Heather McCarrick, Erin Healy, Zeeshan Ahmed, Kam Arnold, Zachary Atkins | Summary: Advances in cosmic microwave background (CMB) science depend on increasing the number of sensitive detectors observing the sky. New instruments deploy large arrays of superconducting transition-edge sensor (TES) bolometers tiled densely into ever larger […]

The eROSITA Final Equatorial-Depth Survey (eFEDS): A multiwavelength view of WISE mid-infrared galaxies/active galactic nuclei

Posted by klaurent June 28, 2021Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Yoshiki Toba, Teng Liu, Tanya Urrutia, Mara Salvato, Junyao Li | Summary: We investigate the physical properties–such as the stellar mass, SFR, IR luminosity, X-ray luminosity, and hydrogen column density–of MIR galaxies and AGN at $z < 4$ in the 140 deg$^2$ field observed by SRG/eROSITA […]

Shot noise and scatter in the star formation efficiency as a source of 21-cm fluctuations

Posted by klaurent June 24, 2021Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Itamar Reis, Rennan Barkana, Anastasia Fialkov, , | Summary: The 21-cm signal from cosmic dawn and the epoch of reionization (EoR) probes the characteristics of the high redshift galaxy population. Many of the astrophysical properties of galaxies at high redshifts are currently unconstrained due to the lack […]

Reinforcement Learning-based Dialogue Guided Event Extraction to Exploit Argument Relations

Posted by klaurent June 23, 2021Caltech

Kavli Affiliate: Lihong Wang | First 5 Authors: Qian Li, Hao Peng, Jianxin Li, Jia Wu, Yuanxing Ning | Summary: Event extraction is a fundamental task for natural language processing. Finding the roles of event arguments like event participants is essential for event extraction. However, doing so for real-life event descriptions is challenging because an […]
