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 […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Yves Benoist, Toshiyuki Kobayashi, , , | Summary: Let G be a real semisimple algebraic Lie group and H a real reductive algebraic subgroup. We describe the pairs (G,H) for which the representation of G in $L^2(G/H)$ is tempered. When G and H are complex Lie groups, […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Yuta Tarumi, Takuma Suda, Freeke van de Voort, Shigeki Inoue, Naoki Yoshida | Summary: We study the production of barium (Ba) and strontium (Sr) in ultrafaint dwarf galaxies (UFDs). Both r- and s- processes produce these elements, and one can infer the contribution of the r-process from […]
Kavli Affiliate: Melania Nynka | First 5 Authors: Mengjiao Xiao, Kerstin M. Perez, Maurizio Giannotti, Oscar Straniero, Alessandro Mirizzi | Summary: We use the first observation of Betelgeuse in hard $X$-rays to perform a novel search for axion-like particles (ALPs). Betelgeuse is not expected to be a standard source of $X$-rays, but light ALPs produced […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Kielan K. Wilcomb, Quinn M. Konopacky, Travis S. Barman, Christopher A. Theissen, Jean-Baptiste Ruffio | Summary: We present moderate-resolution ($Rsim4000$) $K$ band spectra of the "super-Jupiter," $kappa$ Andromedae b. The data were taken with the OSIRIS integral field spectrograph at Keck Observatory. The spectra reveal resolved molecular […]
Kavli Affiliate: Michael Turner | First 5 Authors: Gianmarco Mengaldo, David Moxey, Michael Turner, Rodrigo C. Moura, Ayad Jassim | Summary: We present a successful deployment of high-fidelity Large-Eddy Simulation (LES) technologies based on spectral/hp element methods to industrial flow problems, which are characterized by high Reynolds numbers and complex geometries. In particular, we describe […]
Kavli Affiliate: Naoki Yasuda | First 5 Authors: Dani C. -Y. Chao, James H. -H. Chan, Sherry H. Suyu, Naoki Yasuda, Tomoki Morokuma | Summary: We present a lensed quasar search based on the variability of lens systems in the HSC transient survey. Starting from 101,353 variable objects with i-band photometry in the HSC transient […]
Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, Nicholas P. Warner, , , | Summary: We consider the fate of a massless (or ultra-relativistic massive) string probe propagating down the BTZ-like throat of a microstate geometry in the D1-D5 system. Far down the throat, the probe encounters large tidal forces that […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Irham Taufik Andika, Knud Jahnke, Masafusa Onoue, Eduardo Bañados, Chiara Mazzucchelli | Summary: We present the discovery of PSO J083.8371+11.8482, a weak emission line quasar with extreme star formation rate at $z=6.3401$. This quasar was selected from Pan-STARRS1, UHS, and unWISE photometric data. Gemini/GNIRS spectroscopy follow-up […]
