Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Ling Zhu, Annalisa Pillepich, Glenn van de Ven, Ryan Leaman, Lars Hernquist | Summary: Galactic dynamical structures are fossil records of the assembly histories of galaxies. By analyzing the cosmological hydrodynamical simulation TNG50, we find that a dynamical structure that we call the "hot inner stellar halo," […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Hiromasa Nakatsuka, Kazunori Nakayama, , | Summary: The cosmic microwave background (CMB) observation by the Planck satellite precisely determines primordial curvature fluctuations on larger scales than $mathcal O(1),mathrm{Mpc}$, while the small-scale curvature fluctuation is still less constrained. The constraint on small-scale fluctuations is highly improved […]
Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Robert L. Cook, Liwen Ko, K. Birgitta Whaley, , | Summary: In this work we study the first step in photosynthesis for the limiting extreme case of a single photon interacting with photosystem II (PSII). We model our system using quantum trajectory theory, which allows us […]
Kavli Affiliate: Frank Wise | First 5 Authors: Yi-Hao Chen, Pavel Sidorenko, Enrique Antonio-Lopez, Rodrigo Amezcua-Correa, Frank Wise | Summary: We report a study of soliton self-frequency shifting in hydrogen-filled hollow-core fiber. The combination of hydrogen and short 40-fs input pulses underlies clean and efficient generation of Raman solitons between 1080 and 1600 nm. With […]

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, F. Abudinén, L. Aggarwal | Summary: We present a measurement of the Cabibbo-Kobayashi-Maskawa unitarity triangle angle $ phi_{3} $ (also known as~$gamma$) using a model-independent Dalitz plot analysis of linebreak $B^+to Dleft(K_{S}^{0}h^{+}h^{-}right)h^+$, where $D$ is either a $D^0$ or $bar{D}{}^0$ meson and […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Michele L. Silverstein, Joshua E. Schlieder, Thomas Barclay, Benjamin J. Hord, Wei-Chun Jao | Summary: We present the TESS discovery of the LHS 1678 (TOI-696) exoplanet system, comprised of two approximately Earth-sized transiting planets and a likely astrometric brown dwarf orbiting a bright ($V_J$=12.5, $K_s$=8.3) M2 dwarf […]
Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: The LHCb experiment at CERN has discovered a doubly charmed isoscalar tetraquark $T_{cc}$ with the quantum numbers of $c c bar u bar d$ and mass of about 3875 MeV/$c^2$, decaying to $D^0 D^0 pi^+$ through the […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Thomas Kupfer, Evan B. Bauer, Jan van Roestel, Eric C. Bellm, Lars Bildsten | Summary: We present the discovery of a new double detonation progenitor system consisting of a hot subdwarf B (sdB) binary with a white dwarf companion with an P=76.34179(2) min orbital period. Spectroscopic observations […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Mirko Curti, Connor Hayden-Pawson, Roberto Maiolino, Francesco Belfiore, Filippo Mannucci | Summary: We investigate which physical properties are most predictive of the position of local star forming galaxies on the BPT diagrams, by means of different Machine Learning (ML) algorithms. Exploiting the large statistics from the Sloan […]
