Kavli Affiliate: Michael S. Turner | First 5 Authors: Michael S. Turner, , , , | Summary: The $rmLambda$CDM cosmological model is remarkable: with just 6 parameters it describes the evolution of the Universe from a very early time when all structures were quantum fluctuations on subatomic scales to the present, and it is consistent […]
Kavli Affiliate: Ralf K. Heilmann | First 5 Authors: P. S. Athiray, Amy R. Winebarger, Patrick Champey, Ken Kobayashi, Sabrina Savage | Summary: The Marshall Grazing Incidence X-ray Spectrometer (MaGIXS) is a sounding rocket experiment that observes the soft X-ray spectrum of the Sun from 6.0 – 24 Angstrom (0.5 – 2.0 keV), successfully launched […]

Kavli Affiliate: Michael S. Turner | First 5 Authors: Michael S. Turner, , , , | Summary: I begin by briefly discussing the first two cosmological paradigms, the hot big-bang model and $Lambda$CDM. In discussing the third paradigm, I focus on the issues it must address, what its aspirations should be, and how it might […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: David Robinson, Camille Avestruz, Nickolay Y. Gnedin, , | Summary: Cooling and heating functions describe how radiative processes impact the thermal state of the gas as a function of its temperature and other physical properties. In a most general case they depend on the detailed distributions […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: James Hong, Matthew Fisher, Michaël Gharbi, Kayvon Fatahalian, | Summary: Human pose is a useful feature for fine-grained sports action understanding. However, pose estimators are often unreliable when run on sports video due to domain shift and factors such as motion blur and occlusions. This leads to […]
Kavli Affiliate: J. S. Villasenor | First 5 Authors: Fernando Barbero, Marc Basquens, Valle Varo, Eduardo J. S. Villaseñor, | Summary: The Hamiltonian description of mechanical or field models defined by singular Lagrangians plays a central role in physics. A number of methods are known for this purpose, the most popular of them being the […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Reed Essick, Amanda Farah, Shanika Galaudage, Colm Talbot, Maya Fishbach | Summary: As catalogs of gravitational-wave transients grow, new records are set for the most extreme systems observed to date. The most massive observed black holes probe the physics of pair instability supernovae while providing clues […]
Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Kanato Goto, Masahiro Nozaki, Kotaro Tamaoka, , | Summary: We introduce a subsystem generalization of the spectral form factor via pseudo entropy, the von-Neumann entropy for the reduced transition matrix. We consider a transition matrix between the thermofield double state and its time-evolved state in two-dimensional conformal […]
Kavli Affiliate: Emil J. Martinec | First 5 Authors: Bruno Balthazar, Amit Giveon, David Kutasov, Emil J. Martinec, | Summary: We propose a new $AdS_3/CFT_2$ duality, in which the bulk string theory has a target spacetime $AdS_3$ times a squashed three-sphere $S^3_flat$, and the dual $CFT_2$ is a symmetric product of sigma models on $R_phitimes […]
