Kavli Affiliate: Nergis Mavalvala | Summary:The motion of a mechanical object — even a human-sized object — should be governed by the rules of quantum mechanics. Coaxing them into a quantum state is, however, difficult: the thermal environment masks any quantum signature of the object’s motion. Indeed, the thermal environment also masks effects of proposed […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Bradford Snios, Daniel A. Schwartz, Aneta Siemiginowska, Małgosia Sobolewska, Mark Birkinshaw | Summary: We present Chandra X-ray observations of 14 radio-loud quasars at redshifts $3 < z < 4$, selected from a well-defined sample. All quasars are detected in the 0.5-7.0 keV energy band, and resolved […]
Kavli Affiliate: Yevgeny Stadnik | First 5 Authors: Prateek Agrawal, Martin Bauer, James Beacham, Asher Berlin, Alexey Boyarsky | Summary: With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader particle and astrophysics community for exploring the physics […]
Kavli Affiliate: T. A. Shutt | Summary:LUX-ZEPLIN (LZ) is a dark matter detector expected to obtain world-leading sensitivity to weakly interacting massive particles (WIMPs) interacting via nuclear recoils with a ~7-tonne xenon target mass. This manuscript presents sensitivity projections to several low-energy signals of the complementary electron recoil signal type: 1) an effective neutrino magnetic […]
Kavli Affiliate: Mikhail Kapranov | First 5 Authors: Mikhail Kapranov, , , , | Summary: By Liouville’s theorem, in dimensions 3 or more conformal transformations form a finite-dimensional group, an apparent drastic departure from the 2-dimensional case. We propose a derived enhancement of the conformal Lie algebra which is an infinite-dimensional dg-Lie algebra incorporating not […]
Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Rodolfo Ostilla-Mónico, Ryan McKeown, Michael P. Brenner, Shmuel M. Rubinstein, Alain Pumir | Summary: At high Reynolds number, the interaction between two vortex tubes leads to intense velocity gradients, which are at the heart of fluid turbulence. This vorticity amplification comes about through two different instability […]
Kavli Affiliate: Xian Chen | First 5 Authors: Zucheng Gao, Xian Chen, Yi-Ming Hu, Jian-Dong Zhang, Shunjia Huang | Summary: Gravitational lensing of gravitational waves (GWs) is a powerful probe of the matter distribution in the universe. Here we revisit the wave-optics effects induced by dark matter (DM) halos on the GW signals of merging […]
Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Jia Liu, Navin McGinnis, Carlos E. M. Wagner, Xiao-Ping Wang, | Summary: We report on an interesting realization of the QCD axion, with mass in the range $mathcal{O}(10)$ MeV. It has previously been shown that although this scenario is stringently constrained from multiple sources, the […]
Kavli Affiliate: Donald G. York | First 5 Authors: Britt F. Lundgren, Samantha Creech, Gabriel Brammer, Nathan Kirse, Matthew Peek | Summary: We present the first results from a Hubble Space Telescope WFC3/IR program, which obtained direct imaging and grism observations of galaxies near quasar sightlines with a high frequency of uncorrelated foreground Mg II […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward W. Kolb, Andrew J. Long, Evan McDonough, , | Summary: We study gravitational particle production of the massive spin-$3/2$ Rarita-Schwinger field, and its close relative, the gravitino, in FRW cosmological spacetimes. For masses lighter than the value of the Hubble expansion rate after inflation, $m_{3/2} […]
