Wavelet-Based Characterization of Small-Scale Solar Emission Features at Low Radio Frequencies

Kavli Affiliate: Robert Goeke | First 5 Authors: Akshay Suresh, Rohit Sharma, Divya Oberoi, Srijan B. Das, Victor Pankratius | Summary: Low radio frequency solar observations using the Murchison Widefield Array have recently revealed the presence of numerous weak, short-lived and narrow-band emission features, even during moderately quiet solar conditions. These non-thermal features occur at […]

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 […]

Cherkis bow varieties and Coulomb branches of quiver gauge theories of affine type $A$

Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Hiraku Nakajima, Yuuya Takayama, , , | Summary: We show that Coulomb branches of quiver gauge theories of affine type $A$ are Cherkis bow varieties, which have been introduced as ADHM type description of moduli space of instantons on the Taub-NUT space equivariant under a cyclic group […]

S-folds and 4d N=3 superconformal field theories

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Ofer Aharony, Yuji Tachikawa, Kiyonori Gomi, , | Summary: S-folds are generalizations of orientifolds in type IIB string theory, such that the geometric identifications are accompanied by non-trivial S-duality transformations. They were recently used by Garcia-Etxebarria and Regalado to provide the first construction of four dimensional N=3 […]

Towards a mathematical definition of Coulomb branches of $3$-dimensional $mathcal N=4$ gauge theories, II

Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Alexander Braverman, Michael Finkelberg, Hiraku Nakajima, , | Summary: Consider the $3$-dimensional $mathcal N=4$ supersymmetric gauge theory associated with a compact Lie group $G_c$ and its quaternionic representation $mathbf M$. Physicists study its Coulomb branch, which is a noncompact hyper-K"ahler manifold with an $mathrm{SU}(2)$-action, possibly with singularities. […]

High-Q impurity photon states bounded by a photonic-band-pseudogap in an optically-thick photonic-crystal slab

Kavli Affiliate: Axel Scherer | First 5 Authors: Se-Heon Kim, Andrew Homyk, Sameer Walavalkar, Axel Scherer, | Summary: We show that, taking a two-dimensional photonic-crystal slab system as an example, surprisingly high quality factors (Q) over 10^5 are achievable, even in the absence of a rigorous photonic-band-gap. We find that the density of in-plane Bloch […]
