Hamiltonian approach to 2nd order gauge invariant cosmological perturbations

Kavli Affiliate: Misao Sasaki | First 5 Authors: Guillem Domènech, Misao Sasaki, , , | Summary: In view of growing interest in tensor modes and their possible detection, we clarify the definition of tensor modes up to 2nd order in perturbation theory within the Hamiltonian formalism. Like in gauge theory, in cosmology the Hamiltonian is […]

Ring objects in the equivariant derived Satake category arising from Coulomb branches (with an appendix by Gus Lonergan)

Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Alexander Braverman, Michael Finkelberg, Hiraku Nakajima, , | Summary: This is the second companion paper of arXiv:1601.03586. We consider the morphism from the variety of triples introduced in arXiv:1601.03586 to the affine Grassmannian. The direct image of the dualizing complex is a ring object in the equivariant […]

A pair of Calabi-Yau manifolds from a two parameter non-Abelian gauged linear sigma model

Kavli Affiliate: Kentaro Hori | First 5 Authors: Kentaro Hori, Johanna Knapp, , , | Summary: We construct and study a two parameter gauged linear sigma model with gauge group $(U(1)^2times O(2))/{mathbb Z}_2$ that has a dual model with gauge group $(U(1)^2times SO(4))/{mathbb Z}_2$. The model has two geometric phases, three hybrid phases and one […]

Constraint on the inflow/outflow rates in star-forming galaxies at z~1.4 from molecular gas observations

Kavli Affiliate: Naoyuki Tamura | First 5 Authors: Akifumi Seko, Kouji Ohta, Kiyoto Yabe, Bunyo Hatsukade, Masayuki Akiyama | Summary: We constrain the rate of gas inflow into and outflow from a main-sequence star-forming galaxy at z~1.4 by fitting a simple analytic model for the chemical evolution in a galaxy to the observational data of […]

Light yield of an undoped CsI crystal coupled directly to a photomultiplier tube at 77 Kelvin

Kavli Affiliate: Masaki Yamashita | First 5 Authors: Jing Liu, Masaki Yamashita, Arun Kumar Soma, , | Summary: A light yield of 20.4 $pm$ 0.8 photoelectrons/keV was achieved with an undoped CsI crystal coupled directly to a photomultiplier tube at 77 Kelvin. This is by far the largest yield in the world achieved with CsI […]

Visible camera cryostat design and performance for the SuMIRe Prime Focus Spectrograph (PFS)

Kavli Affiliate: Naoyuki Tamura | First 5 Authors: Stephen A. Smee, James E. Gunn, Mirek Golebiowski, Stephen C. Hope, Fabrice Madec | Summary: We describe the design and performance of the SuMIRe Prime Focus Spectrograph (PFS) visible camera cryostats. SuMIRe PFS is a massively multi-plexed ground-based spectrograph consisting of four identical spectrograph modules, each receiving […]

High purity NaI(Tl) scintillator to search for dark matter

Kavli Affiliate: Kunio Inoue | First 5 Authors: Ken-Ichi Fushimi, Hiroyasu Ejiri, Ryuta Hazama, Haruo Ikeda, Kunio Inoue | Summary: A high purity and large volume NaI(Tl) scintillator was developed to search for cosmic dark matter. The required densities of radioactive impurities (RIs) such as U-chain, Th-chain are less than a few ppt to establish […]
