Kavli Affiliate: Oskar Painter | First 5 Authors: Hengjiang Ren, Tirth Shah, Hannes Pfeifer, Christian Brendel, Vittorio Peano | Summary: Recent advances in cavity-optomechanics have now made it possible to use light not just as a passive measuring device of mechanical motion, but also to manipulate the motion of mechanical objects down to the level […]
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: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, , , | Summary: We consider Weyl gauge theories of gravity (WGTs), which are invariant both under local Poincar’e transformations and local changes of scale. Such theories may be interpreted as gauge theories in Minkowski spacetime, but their gravitational interactions are most often […]
Kavli Affiliate: Tomoyuki Abe | First 5 Authors: Tomoyuki Abe, Christopher Lazda, , , | 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 […]
Kavli Affiliate: Tomoyuki Abe | First 5 Authors: Tomoyuki Abe, Christopher Lazda, , , | Summary: For any separated, taut, locally of $^+$weakly finite type morphism $f:Xrightarrow Y$ between finite dimensional, analytic adic spaces, we construct the higher direct images with compact support $mathbf{R}^qf_!mathscr{F}$ of any abelian sheaf $mathscr{F}$ on $X$. The basic approach follows […]
Kavli Affiliate: Gregory Herczeg | First 5 Authors: Yong-Hee Lee, Doug Johnstone, Jeong-Eun Lee, Gregory Herczeg, Steve Mairs | Summary: While young stellar objects sometimes undergo bursts of accretion, these bursts usually occur sporadically, making them challenging to study observationally and to explain theoretically. We build a schematic description of cyclical bursts of the young […]
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: Yukinobu Toda | First 5 Authors: Yalong Cao, Yukinobu Toda, , , | Summary: Let $X$ be a Calabi-Yau 4-fold and $D$ a smooth divisor on it. We consider tautological complex associated with $L=mathcal{O}_X(D)$ on the moduli space of Le Potier stable pairs and define its counting invariant by integrating the Euler class […]
