Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Andrew Vanderburg, Saul A. Rappaport, Siyi Xu, Ian Crossfield, Juliette C. Becker | Summary: Astronomers have discovered thousands of planets outside the solar system, most of which orbit stars that will eventually evolve into red giants and then into white dwarfs. During the red giant phase, […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Stefania Amodeo, Nicholas Battaglia, Emmanuel Schaan, Simone Ferraro, Emily Moser | Summary: The thermal and kinematic Sunyaev-Zel’dovich effects (tSZ, kSZ) probe the thermodynamic properties of the circumgalactic and intracluster medium (CGM and ICM) of galaxies, groups, and clusters, since they are proportional, respectively, to the integrated […]
Kavli Affiliate: Tomoyuki Abe | Summary:We construct proper pushforwards for partially proper morphisms of analytic adic spaces. This generalises the theory due to van der Put in the case of rigid analytic varieties over a non-Archimedean field. For morphisms which are smooth and partially proper in the sense of Kiehl, we furthermore construct the trace […]
Kavli Affiliate: Farhan Rana | First 5 Authors: Farhan Rana, Okan Koksal, Minwoo Jung, Gennady Shvets, Christina Manolatou | Summary: Optical absorption and emission spectra of doped two-dimensional (2D) materials exhibit sharp peaks that are often identified with pure excitons and pure trions (or charged excitons), but both peaks have been recently attributed to superpositions […]
Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: Structure in the di-$J/psi$ mass spectrum observed by the LHCb experiment around 6.9 and 7.2 GeV is interpreted in terms of $J^{PC}=0^{++}$ and $2^{++}$ resonances between a $cc$ diquark and a $bar c bar c$ antidiquark, using […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: D. Kandel, Roger W. Romani, Alexei V. Filippenko, Thomas G. Brink, WeiKang Zheng | Summary: We analyze photometry and spectra of the "redback" millisecond pulsar binary J2339$-$0533. These observations include new measurements from Keck and GROND, as well as archival measurements from the OISTER, WIYN, SOAR, […]
Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Anna V. Payne, Benjamin J. Shappee, Jason T. Hinkle, Patrick J. Vallely, Christopher S. Kochanek | Summary: We present the discovery that ASASSN-14ko is a periodically flaring AGN at the center of the galaxy ESO 253-G003. At the time of its discovery by the All-Sky Automated […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward W. Kolb, Andrew J. Long, , , | Summary: Starting with the de Broglie–Proca Lagrangian for a massive vector field, we calculate the number density of particles resulting from gravitational particle production (GPP) during inflation, with detailed consideration to the evolution of the number density […]
Kavli Affiliate: Katia Bertoldi | First 5 Authors: Gabriele Librandi, Eleonora Tubaldi, Katia Bertoldi, , | Summary: Nonreciprocity can be passively achieved by harnessing material nonlinearities. In particular, networks of nonlinear bistable elements with asymmetric energy landscapes have recently been shown to support unidirectional transition waves. However, in these systems energy can be transferred only […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Hiroki Yoneda, Kazuo Makishima, Teruaki Enoto, Dmitry Khangulyan, Takahiro Matsumoto | Summary: To understand the nature of the brightest gamma-ray binary system LS 5039, hard X-ray data of the object, taken with the Suzaku and NuSTAR observatories in 2007 and 2016, respectively, were analyzed. The two data […]
