Kavli Affiliate: Roger W. Romani | First 5 Authors: Pavan R. Hebbar, Craig O. Heinke, D. Kandel, Roger W. Romani, | Summary: Redback millisecond pulsars (MSPs) typically show pronounced orbital variability in their X-ray emission due to our changing view of the intrabinary shock (IBS) between the pulsar wind and stellar wind from the companion. […]
Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: Theron W. Carmichael, Samuel N. Quinn, George Zhou, Nolan Grieves, Francois Bouchy | Summary: We report the discovery of two transiting brown dwarfs (BDs), TOI-811b and TOI-852b, from NASA’s Transiting Exoplanet Survey Satellite mission. These two transiting BDs have similar masses, but very different radii and […]
Kavli Affiliate: David A. Weitz | First 5 Authors: Peng Zhang, Christian Kern, Sijie Sun, David A. Weitz, Pai Wang | Summary: We demonstrate a new class of elastic waves in the bulk: When longitudinal and transverse components propagate at the same speed, rolling waves with a spin that is not parallel to the wave […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: J. R. Rigby, Michael Florian, A. Acharyya, Matthew Bayliss, Michael D. Gladders | Summary: For the extremely bright lensed galaxy SDSS J1723+3411 at z=1.3293 , we analyze spatially integrated MMT, Keck, and Hubble Space Telescope spectra that fully cover the rest-frame wavelength range of 1400 to […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Min Fang, Lynne A. Hillenbrand, Jinyoung Serena Kim, Krzysztof Findeisen, Gregory J. Herczeg | Summary: We present a spectroscopic survey of over 3400 potential members in the North America and Pelican nebulae (NAP) using several low-resolution ($Rapprox$ 1300-2000) spectrographs: Palomar/Norris, WIYN/HYDRA, Keck/DEIMOS, and MMT/Hectospec. We identify […]
Kavli Affiliate: Farhan Rana | First 5 Authors: Farhan Rana, Okan Koksal, Minwoo Jung, Gennady Shvets, A. Nick Vamivakas | Summary: We present a many-body theory for exciton-trion-polaritons in doped two-dimensional materials. Exciton-trion-polaritons are robust coherent hybrid excitations involving excitons, trions, and photons. Signatures of these polaritons have been recently seen in experiments. In these […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Hongjun An, Roger W. Romani, , , | Summary: We report on X-ray measurements constraining the spectral energy distribution (SED) of the high-redshift $z=5.18$ blazar SDSS J013127.34$-$032100.1 with new XMM-Newton and NuSTAR exposures. The blazar’s X-ray spectrum is well fit by a power law with $Gamma=1.9$ […]
Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yalong Cao, Yukinobu Toda, , , | Summary: Nagao-Nakajima introduced counting invariants of stable perverse coherent systems on small resolutions of Calabi-Yau 3-folds and determined them on the resolved conifold. Their invariants recover DT/PT invariants and Szendr"oi’s non-commutative invariants in some chambers of stability conditions. In this […]
Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Sebastian Baum, Marcela Carena, Nausheen R. Shah, Carlos E. M. Wagner, Yikun Wang | Summary: Electroweak baryogenesis is an attractive mechanism to generate the baryon asymmetry of the Universe via a strong first order electroweak phase transition. We compare the phase transition patterns suggested by […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Yves Benoist, Toshiyuki Kobayashi, , , | Summary: Let G be a complex semisimple Lie group and H a complex closed connected subgroup. Let g and h be their Lie algebras. We prove that the regular representation of G in $L^2(G/H)$ is tempered if and only if […]
