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. […]
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 […]
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 […]
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 […]
Kavli Affiliate: Brian Nord | First 5 Authors: Adam Shandonay, Robert Morgan, Keith Bechtol, Clecio R. Bom, Brian Nord | Summary: Searches for counterparts to multimessenger events with optical imagers use difference imaging to detect new transient sources. However, even with existing artifact detection algorithms, this process simultaneously returns several classes of false positives: false […]
Kavli Affiliate: C. L. Kuo | First 5 Authors: J. A. Sobrin, A. J. Anderson, A. N. Bender, B. A. Benson, D. Dutcher | Summary: SPT-3G is the third survey receiver operating on the South Pole Telescope dedicated to high-resolution observations of the cosmic microwave background (CMB). Sensitive measurements of the temperature and polarization anisotropies […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Vidya Muthukumar, Christos Thrampoulidis, , | Summary: The literature on "benign overfitting" in overparameterized models has been mostly restricted to regression or binary classification; however, modern machine learning operates in the multiclass setting. Motivated by this discrepancy, we study benign overfitting in multiclass linear classification. […]
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Hongyuan Li, Shaowei Li, Emma C. Regan, Danqing Wang, Wenyu Zhao | Summary: The Wigner crystal state, first predicted by Eugene Wigner in 1934, has fascinated condensed matter physicists for nearly 90 years2-14. Studies of two-dimensional (2D) electron gases first revealed signatures of the Wigner crystal […]
Kavli Affiliate: Ronald Hanson | First 5 Authors: Weiqi Ji, Xingyu Su, Bin Pang, Sean Joseph Cassady, Alison M. Ferris | Summary: Combustion kinetic modeling is an integral part of combustion simulation, and extensive studies have been devoted to developing both high fidelity and computationally affordable models. Despite these efforts, modeling combustion kinetics is still […]
Kavli Affiliate: Ariel Amir | First 5 Authors: Ahmad Zareei, Deng Pan, Ariel Amir, , | Summary: We study the dynamics of flow-networks in porous media using a pore-network model. First, we consider a class of erosion dynamics assuming a constitutive law depending on flow rate, local velocities, or shear stress at the walls. We […]
