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: Daniel C. Ralph | First 5 Authors: Arnab Bose, Rakshit Jain, Jackson J. Bauer, Robert A. Buhrman, Caroline A. Ross | Summary: We compare thermal-gradient-driven transverse voltages in ferrimagnetic-insulator/heavy-metal bilayers (Tm3Fe5O12/W and Tm3Fe5O12/Pt) to corresponding electrically-driven transverse resistances at and above room temperature. We find for Tm3Fe5O12/W that the thermal and electrical effects […]
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, 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 […]
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 […]
