Nature of novel moiré exciton states in WSe$_2$/WS$_2$ heterobilayers

Kavli Affiliate: Feng Wang | First 5 Authors: Mit H. Naik, Emma C. Regan, Zuocheng Zhang, Yang-hao Chan, Zhenglu Li | Summary: Moir’e patterns of transition metal dichalcogenide (TMD) heterobilayers have proven to be an ideal platform to host unusual correlated electronic phases, emerging magnetism, and correlated exciton physics. While the existence of novel moir’e […]

Cosmology with one galaxy?

Kavli Affiliate: David N. Spergel | First 5 Authors: Francisco Villaescusa-Navarro, Jupiter Ding, Shy Genel, Stephanie Tonnesen, Valentina La Torre | Summary: Galaxies can be characterized by many internal properties such as stellar mass, gas metallicity, and star-formation rate. We quantify the amount of cosmological and astrophysical information that the internal properties of individual galaxies […]

Tidally Tilted Pulsators

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Gerald Handler, Rahul Jayaraman, Donald W. Kurtz, Jim Fuller, Saul A. Rappaport | Summary: The tidally tilted pulsators are a new type of oscillating star in close binary systems that have their pulsation axis in the orbital plane because of the tidal distortion caused by their […]

A census of 163 large-scale (>=10 pc), velocity-coherent filaments in inner Galactic plane: physical properties, dense gas fraction, and association with spiral arms

Kavli Affiliate: Ke Wang | First 5 Authors: Yifei Ge, Ke Wang, , , | Summary: The interstellar medium has a highly filamentary and hierarchical structure, which may play a significant role in star formation. A systematical study on the large-scale filaments towards their physical parameters, distribution, structures and kinematics will inform us of what […]

Augmenting astrophysical scaling relations with machine learning : application to reducing the SZ flux-mass scatter

Kavli Affiliate: David N. Spergel | First 5 Authors: Digvijay Wadekar, Leander Thiele, Francisco Villaescusa-Navarro, J. Colin Hill, Miles Cranmer | Summary: Complex systems (stars, supernovae, galaxies, and clusters) often exhibit low scatter relations between observable properties (e.g., luminosity, velocity dispersion, oscillation period, temperature). These scaling relations can illuminate the underlying physics and can provide […]

Classification of solutions to several semi-linear polyharmonic equations and fractional equations

Kavli Affiliate: Feng Yuan | First 5 Authors: Zhuoran Du, Zhenping Feng, Yuan Li, , | Summary: We are concerned with the following semi-linear polyharmonic equation with integral constraint begin{align} left{begin{array}{rl} &(-Delta)^pu=u^gamma_+ ~~ mbox{ in }{mathbb{R}^n},\ nonumber &int_{mathbb{R}^n}u_+^{gamma}dx<+infty, end{array}right. end{align} where $n>2p$, $pgeq2$ and $pinmathbb{Z}$. We obtain for $gammain(1,frac{n}{n-2p})$ that any nonconstant solution satisfying certain […]
