Kavli Affiliate: Jing Wang | First 5 Authors: Kai Liu, Keke Bai, Jing Wang, Juntao Song, Ying Liu | Summary: Antimonene is a novel two-dimensional topological semiconductor material with strain driven tunable electronic structure for future electronic and spintronic devices, but the growth of clean antimonene is not fully understood. In this work, the growth […]
Kavli Affiliate: David A. Principe | First 5 Authors: Steven M. Silverberg, Hans Moritz Guenther, Jinyoung Serena Kim, David A. Principe, Scott J. Wolk | Summary: Empirically, the estimated lifetime of a typical protoplanetary disk is $<5-10$ Myr. However, the disk lifetimes required to produce a variety of observed exoplanetary systems may exceed this timescale. […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman, Abigail Lee, , | Summary: We present an absolute calibration of the J-region Asymptotic Giant Branch (JAGB) method using published photometry of resolved stars in 20 nearby galaxies observed with HST using the WFC3-IR camera and the F110W (Broad J-Band) […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, , , , | Summary: Handedness, or chirality, has been a continuing source of inspiration across a wide range of scientific problems. After a quick review of some important, instructive historical examples, I present three contemporary case studies involving sophisticated applications of chirality at the […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Wei-Yang Wang, Jin-Chen Jiang, Jiguang Lu, Heng Xu, Jiangwei Xu | Summary: Fast radio bursts (FRBs) are millisecond-duration signals, to be highly dispersed at distant galaxies, the physical origin of which is still challenging. Coherent curvature emission by bunches powered, e.g., by starquakes, has already been proposed […]

Kavli Affiliate: Jing Wang | First 5 Authors: Shun Wang, Jing Wang, Bi-Qing For, Bumhyun Lee, Tristan Reynolds | Summary: We study the tidal interaction of galaxies in the Eridanus supergroup, using HI data from the pre-pilot survey of WALLABY (Widefield ASKAP L-band Legacy All-sky Blind surveY). We obtain optical photometric measurements and quantify the […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Fangzheng Shi, Bocheng Zhu, Zhiyuan Li, Feng Yuan, | Summary: Super-massive black holes (SMBHs) spend most of their lifetime accreting at a rate well below the Eddington limit, manifesting themselves as low-luminosity active galactic nuclei (LLAGNs). The prevalence of a hot wind from LLAGNs is a generic […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Avi Kaplan-Lipkin, Bruce Macintosh, Alexander Madurowicz, Sowmya Krishnamurthy, Alexander Shapiro | Summary: Astrometric detection of exoplanets by stellar reflex motion will be made possible for giant planets by the recent Gaia mission and for Earth-like planets by proposed missions such as LUVOIR. At the theoretical limits, astrometry […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Avi Kaplan-Lipkin, Bruce Macintosh, Alexander Madurowicz, Krishnamurthy Sowmya, Alexander Shapiro | Summary: Astrometry has long been a promising technique for exoplanet detection. At the theoretical limits, astrometry would allow for the detection of smaller planets than previously seen by current exoplanet search methods, but stellar activity may […]
