Kavli Affiliate: J. S. Villasenor | First 5 Authors: Juan Margalef-Bentabol, Eduardo J. S. Villaseñor, , , | Summary: We analyze in full-detail the geometric structure of the covariant phase space (CPS) of any local field theory defined over a space-time with boundary. To this end, we introduce a new frame: the "relative bicomplex framework". […]
Kavli Affiliate: Yasunori Nomura | First 5 Authors: Chitraang Murdia, Yasunori Nomura, Pratik Rath, , | Summary: Motivated by the understanding of holography as realized in tensor networks, we develop a bulk procedure that can be interpreted as generating a sequence of coarse-grained holographic states. The coarse-graining procedure involves identifying degrees of freedom entangled at […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Shin Kobayashi, Yuhei Nakayama, Satoshi Shirai, | Summary: Recently, the XENON1T collaboration reported an excess in the electron recoil energy spectrum. One of the simplest new physics interpretation is a new neutrino-electron interaction mediated by a light vector particle. However, for the parameter region favored […]
Kavli Affiliate: Moritz Guenther | First 5 Authors: Michihiro Takami, Tracy L. Beck, P. Christian Schneider, Hans Moritz Guenther, Marc White | Summary: For the active T-Taur star RW Aur A we have performed long-term (~10 yr) monitoring observations of (1) jet imaging in the [Fe II] 1.644-micron emission line using Gemini-NIFS and VLT-SINFONI; (2) […]
Kavli Affiliate: Aaron Roodman | First 5 Authors: Hung-Jin Huang, Tim Eifler, Rachel Mandelbaum, Gary M. Bernstein, Anqi Chen | Summary: Measurements of large-scale structure are interpreted using theoretical predictions for the matter distribution, including potential impacts of baryonic physics. We constrain the feedback strength of baryons jointly with cosmology using weak lensing and galaxy […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Ryota Tomaru, Chris Done, Ken Ohsuga, Hirokazu Odaka, Tadayuki Takahashi | Summary: We fit the observed high ionisation X-ray absorption lines in the neutron star binary GX13+1 with a full simulation of a thermal-radiative wind. This uses a radiation hydrodynamic code coupled to Monte Carlo radiation transfer […]
Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Roxana Rosca-Mead, Christopher J. Moore, Ulrich Sperhake, Michalis Agathos, Davide Gerosa | Summary: We compute families of spherically symmetric neutron-star models in two-derivative scalar-tensor theories of gravity with a massive scalar field. The numerical approach we present allows us to compute the resulting spacetimes out to infinite […]
Kavli Affiliate: John Silverman | First 5 Authors: Kentaro Nagamine, Ikkoh Shimizu, Katsumi Fujita, Nao Suzuki, Khee-Gan Lee | Summary: In preparation for the IGM tomography study by Subaru Prime Focus Spectrograph (PFS) survey and other large future telescopes such as TMT/ELT/GMT, we present the results of our pilot study on Ly$alpha$ forest and IGM […]
Kavli Affiliate: Chiaki Hikage | First 5 Authors: Chiaki Hikage, Ryuichi Takahashi, Kazuya Koyama, , | Summary: We explore the covariance of redshift-space matter power spectra after a standard density-field reconstruction. We derive perturbative formula of the covariance at the tree-level order and find that the amplitude of the off-diagonal components from the trispectrum decreases […]
Kavli Affiliate: Xian Chen | First 5 Authors: Manuel Arca-Sedda, Pau Amaro-Seoane, Xian Chen, , | Summary: We study the formation of intermediate-mass ratio inspirals (IMRIs) triggered by the interactions between two stellar black holes (BHs) and an intermediate-mass BH (IMBH) inhabiting the centre of a dense star cluster. We exploit $N$-body models varying the […]
