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 […]
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: James Bock | First 5 Authors: Lionel Duband, Thomas Prouve, James Bock, Lorenzo Moncelsi, Alessandro Schillaci | Summary: In the field of astrophysics, the faint signal from distant galaxies and other dim cosmological sources at millimeter and submillimeter wavelengths require the use of high-sensitivity experiments. Cryogenics and the use of low-temperature detectors are […]
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: Daniel J. Needleman | First 5 Authors: Sebastian Fürthauer, Daniel J Needleman, Michael J. Shelley, , | Summary: Living matter moves, deforms, and organizes itself. In cells this is made possible by networks of polymer filaments and crosslinking molecules that connect filaments to each other and that act as motors to do mechanical […]
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 […]
