Kavli Affiliate: Naoki Yasuda | First 5 Authors: Ichiro Takahashi, Nao Suzuki, Naoki Yasuda, Akisato Kimura, Naonori Ueda | Summary: The advancement of technology has resulted in a rapid increase in supernova (SN) discoveries. The Subaru/Hyper Suprime-Cam (HSC) transient survey, conducted from fall 2016 through spring 2017, yielded 1824 SN candidates. This gave rise to […]
Kavli Affiliate: Tom Melia | First 5 Authors: Andrew J. Larkoski, Tom Melia, , , | Summary: We covariantize calculations over the manifold of phase space, establishing Stokes’ theorem for differential cross sections and providing new definitions of familiar observable properties like infrared and collinear safety. Through the introduction of explicit coordinates and a metric […]
Kavli Affiliate: Yasunori Nomura | First 5 Authors: Kevin Langhoff, Yasunori Nomura, , , | Summary: In understanding the quantum physics of a black hole, nonperturbative aspects of gravity play important roles. In particular, huge gauge redundancies of a gravitational theory at the nonperturbative level, which are much larger than the standard diffeomorphism and relate […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Kohei Hayashi, Masahiro Ibe, Shin Kobayashi, Yuhei Nakayama, Satoshi Shirai | Summary: Self-interacting dark matter (SIDM) has gathered growing attention as a solution to the small scale problems of the collisionless cold dark matter (DM). We investigate the SIDM using stellar kinematics of 23 ultra-faint dwarf (UFD) […]
Kavli Affiliate: Tomoyuki Abe | First 5 Authors: Tomoyuki Abe, , , , | Summary: Bivariant theory is a unified framework for cohomology and Borel-Moore homology theories. In this paper, we extract an $infty$-enhanced bivariant homology theory from Gaitsgory-Rozenblyum’s six functor formalism. | Search Query: ArXiv Query: search_query=au:”Tomoyuki Abe”&id_list=&start=0&max_results=10 Read More
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: 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: 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 […]
